Delidded my K, are the temps OK, or should I expect better?
My main preoccupation is with the delid process itself and if I applied the LM correctly (since this is the very first time I do this), not with how far I can OC the chip. To be completely fair, I mostly bought the whole thing because I was bored and wanted something new to tinker with. The 5GHz literally makes no difference with the ti in the few games I rarely play, and for my work which is mostly Indesign, Photoshop, Illustrator etc., there's no way I can notice +MHz.
Your temperature and voltage for a delidded K are pretty average

The chip is either a dud or half decent I guess, depending on who you are talking with. Almost nobody uses AVX2 for stresstesting OCs, although I've seen some with incredible chips that can do 5GHz at V even with AVX. This chip is nowhere near that. I'd say it's mostly on par with the 5GHz chips Sillicon Lottery sells, that run at V and -2 AVX offset, so AVX at V basically, maybe a bit better, as for me V at GHz seem to be stable with AVX2.
The memory is a super weird ADATA wityh Spektek chips, it gave me 1 year of troubles, without exaggeration. I was unable to get things stable at its XMP of MHz and CL16 at all for months, because I made the mistake to try and increase voltages. It was exactly the DRAM voltage that made things unstable. It's at V now and manually entered XMP timings, fully stable, no app crash in months, 0 BSODs, 48 hrs of stresstesting in both LinpackX and Blend with AVX2 and 10GB RAM used, also with the memory test suggested by ASUS inside Linux.
Run system stock and test the memory then apply cpu oc.
Most errors I get are fro. Memory tweaking more so than cpu overclock, however this is my experience while I do Not use the pc everyday but for benchmarking only. So errors for me are much less concern.
mhz cas 14 bench stable but immediately throws errors.
Cas 15 can get minutes before errors.
Cas 16 mhz much more stable longer duration without errors.
All this at stock cpu speeds during my testing.
I use Aida for latency test.
Pimod for effeciency. (32m)
This generally how I test.
OCCT AVX and AVX2 and none. Test all 3.
Then Linpack for heavier memory loads and stability testing can choose amount of memory used.

In short, the RAM is rock solid stable (now). Had to compromise in a few places to get everything I wanted when I got this in , and this RAM was cheapest, I guess for obvious reasons.
I think I will see if everything remains stable at +V adaptive and no AVX offset, 5GHz, in day to day usage. If I see apps crashing or BSODs I'll probably use an AVX offset. The CPU seems to have dropped 25C or so at higher OC/power draws (W+). I remember very well having it thermally throttle if I tried SmallFFTs no AVX at 5GHz/V, reaching C. Now it tops at 74C max core temp and the core averages are Package temp peaks at 75C like this, average 72C. The C seems in line with the expectations for LM I guess?
Below is SmallFFTs no AVX, 5GHz/+V, increased it a bit to make the CPU hotter, see how the LM does.
Safe CPU Temps: How Hot Should My CPU Be?
In this guide, weve detailed how you can check your CPU temperatures and determine whether or not your processor is operating in a safe range.
Whether you have just built your own computer, or youve got an older system that you want to check up on, it is always a good idea to monitor you CPUs temperature
But monitoring your processors temperature wont do you any good if you dont know what temperature it should be running at. In this guide, well show you how to check your processors noprmal temperature range. Well also help you figure out how hot your CPU should be running.
Because, ultimately, every processor is built to run at slightly different temperature ranges. And, there is really not a one-size-fits-all approach to determing normal CPU temperature ranges.
(If you are looking for a quick answer, we have attempted to give you a one-size-fits-all answer below. But, just know that it will never be a great way to determine whether or not your CPU temps are too high or not.)
In any case, though, after reading through this guide, youll have a solid understanding of safe CPU temps. Youll also learn how to determine whether or not your processor is running at the appropriate temperature.
The Quick Answer Are Your CPU Temps too High?
Again, there is no way to give you an accurate one-size-fits-all answer to whether or not your CPU temperatures are too high or not. Normal CPU temps are going to vary quite a bit depending on the processor. I suggest that you read this guide in full to gain a better understanding on how you should proparly check and see what temperature your CPU (or, rather, your CPUs cores) should be running at.
But, as a generalization that might help you identify a serious problem, if you have an Intel processor, you could say that a CPU core temperature of over degrees Celsius while idling and/or a temperature of over degrees Celsius while under full load is probably a cause for concern.
If you have an AMD Ryzen processor, you could say that a CPU core temperature of over degrees Celsius while idling and/or a temperature of over degrees (depending on the Ryzen generation) Celsius while under full load is probably be cause for concern.
So, in other words, if your CPU is hitting those temperatures on a regular basis, you will likely want to dive into the problem further and see what is going on.
Again, this is a generalization. Its probably not the best way to figure out if your temperatures are appropriate or not. For a better way to check and understand whether or not your processors temperatures are acceptable or not, keep reading this guide.
How to Check Your CPUs Temperature
First off, before you can determine whether or not you are getting safe CPU temperatures, you will need some way to check and see what temperature your processors cores are actually running at.
There are quite a few different ways to do this.
You can check your CPU core temperature directly through your motherboards BIOS. However, this reading will only give you the idle temp for your CPU and wont help you when stress testing your system. And, the temperature shown in your BIOS will always be a bit higher reading than what it will be when the system is idling in Windows, because BIOS will always boot your processor using higher voltage levels in order to make sure that it will initialize.
To get a better reading on the temperature range that your processors runs at (at both idle and under load), youll want to use third-party software.
There are quite a few different programs out there that will let you monitor your CPU temperatures (and some will monitor the temperature on your other components, too.)
- Core Temp
- Open Hardware Monitor
Check CPU Temp with Core Temp
Ill use Core Temp to check my processors temperature.
As you can see, I have an Intel Core iK processor, which is a six-core CPU. Core Temp shows you what the individual temperature is on each one of those six-cores. At the time of taking this screen shot you can see that my processors cores are running at an average of about ~degrees Celsius.
And, since Core Temp also shows me what the processors load is, I can tell that these temperature readings are coming from when the CPU is idling (the screenshot shows that my CPU is at less than 5% load, which means it is idle.)
So, we can say that my temperature is idling at about degrees Celsius.
To check what my temperature is under a heavier load, you could play a demanding game (like PUBG, or Battlefield 1), or render a video, or do something else taxing. But, in order to guarantee a proper % load on your processor, youll want to use a stress-test benchmark tool.
Using Prime95 to Stress-Test
There are a number of stress-test tools out there and there is a lot of discussion on which one is the best to use. I use the SmallFFT test on Prime95 v The SmallFFT test on newer versions of Prime95 will actually push your processor past realistic levels and, therefore, is not a great method to use if you are trying to determine whether or not your CPU temps are safe or not.
You can disable the feature that causes the test to push your processor the extreme by adding a line of code to a specific file in the program, but for meand likely for other usersits easier to just download the older version.
But, the general consensus is that Prime95 v gets about as close to a true % load as any CPU stress-test tool out there. So, thats what I use.
Now, using Prime95s (v) SmallFFTs stress-test to put my system under full load, I get the following temperatures:
Here you can see that under % load, my CPUs cores are running at about an average of ~degrees Celsius.
So, now that I have those numbers, how do I know if degrees Celsius while idling and degrees Celsius under full load is a good range of CPU temperatures for my processor?
While I can tell you that those are generally safe CPU temperatures for the K (at stock settings and with the cooler I have), there are a few things that I had to consider first before declaring that those are CPU temperatures I can live with.
You Know Your CPUs Normal Temp at Idle and Under Load Now What?
Step one is finding out what your processors average temperatures are at idle and while under load. Once you have those temperatures, then you can seek out whether or not they are normal.
However, Intel and AMD do not provide specific numbers of what are considered normal temperatures for your processor. And, there really isnt anywhere on the web that will give you that information outright, either.
That is partly because there are many factors that will determine what temperature your processors cores should be running at. And, if a CPU manufacturer suggested a one-size-fits-all recommended operating temperature, it would likely cause more harm than good.
So, one of the only ways that you can get a good idea of what your CPU temps should be, is just by comparing the temperatures you are getting to the temperatures that others who have the same processor and similar setups are getting. Whether thats by checking forum posts, or by reading/watching others conduct reviews on the processor you have.
Fortunately, there are so many enthusiasts out there that there is likely enough information available for you to determine what the proper range of temperatures your CPUs cores should be running at for various use-cases.
Now, Intel does provide a maximum operating temperature, which we will get into in just a moment. And, if you have an Intel processor, that maximum operating temperature will help you determine whether or not your temperatures are approaching (or hitting) a level that is definitely too high.
But, before we get into that, lets first go over some of the many factors that will play a role in determining what temperature your processors cores should be running at.
1. Optimal CPU Temps Will Vary Depending on the Processor You Have
An Intel Core iK is going to run at different temperatures than an older Intel Core i at idle and when under load.
An AMD Ryzen 9 X is going to run at different temperatures than an AMD Ryzen 3 at idle and when under load.
The iQM processor in an old laptop is going to run at different temperatures than a desktop processor, or than a newer Intel Core iG7 laptop CPU.
Most processors run at different temperatures, whether by slightly differing amounts, or by significant temperature differences.
So, the first thing you need to understand is that you shouldnt compare the temperatures you are getting to the temperatures someone else is getting who has a completely different processor.
2. You Must Take Ambient Temperature Into Consideration
The next thing you need to consider is ambient temperature (or room temperature).
Lets say you just built a new computer with an iK and you fire it up and you see that your processor is idling at degrees Celsius. You think to yourself, I guess thats okay, because I saw someones benchmark on YouTube where they were running their K at about degrees Celsius. But, why is my processor running 3-degrees Celsisus higher than theirs?
Well, its possible that the room temperature where your computer is operating is higher than the room temperature where the benchmark you saw took place. And, that difference in room temperature is why your processor is running at a higher temperature than the benchmarked processor.
So, before you freak out, make sure you take into account the room temperature your computer is operating in and factor that in.
And, this is especially true if youre going to start Googling what temperatures others are getting their processor to run at. Because if you stumble onto a forum where someone is posting that they are getting lower temperatures than you are with the same processor, you dont want to jump to conclusions. It may just be that that person has their computer in a much cooler room than yours.
Generally speaking, Id guess that most people run their computers in rooms that have temperatures of degrees Celsius. But there are definitely others who will prefer rooms much cooler or warmer, depending on their preferences.
In any case, ambient temperature (or room temperature) is an incredibly important factor to consider when trying to determine whether or not your CPU temps are too high.
Of course, you could be getting higher or lower CPU temperatures than others for a few other reasons, too. And, one of those reasons could be that you or they are using a better CPU Cooler and/or thermal paste.
3. The Better Your CPU Cooler, the Better Your CPU Temps
Right now I am using a mm AIO cooler. My cooler is quite a bit better than the stock cooler that came with my processor and, as such, I expect to see lower CPU temperatures from my system than someone else who is using the stock cooler will see.
However, there are also system builders out there who have the iK under an extreme custom-loop water-cooled setup. And, those builders will be getting lower temperatures than I am.
So, its important to factor in what CPU cooler you have before determining whether or not your temperatures are appropriate or not.
And, the same is true for the thermal paste you are using. Generally speaking, the stock thermal paste that comes applied on Intels stock coolers is not going to give as good of heat transfer as a high-end thermal compound will and, as a result, the stock thermal paste will produce higher CPU temperatures.
So, be sure that if you are comparing your temperatures with others who have the same processor as you, that you are taking into consideration the cooler your are using and the quality of the thermal paste that you have applied.
4. A Better Case With Higher Airflow Will Mean Better CPU Temps
Another thing to consider in determining whether or not your temperatures are appropriate or not is the amount of airflow you are getting in your case.
You may have an identical processor and CPU cooler combination as someone else, but you may be getting higher CPU temperatures because that someone else has a better case that is pushing more air over their processor.
So, again, if someone is posting that they are getting better temperatures than you, be sure that you are considering the fact that they could have a setup that allows for more airflow (and, thus, lower temperatures.)
5. Overclocking is Going to Produce Higher Temperatures
Another factor that you should be aware of when determining your processors temperatures, is overclocking.
Overclocking is the act of setting your CPU to run faster than it runs at stock settings. The faster you run it, the hotter it will get.
Of course, that extra heat can be offset by better cooling.
However, if you have overclocked your processor, you are going to have to look at your CPU temperatures with that in mind. You wont want to compare your overclocked CPUs temperatures to the temperatures that someone else who has the same CPU running at stock speeds is getting.
Max CPU Temperatures How Hot is Too Hot
Ive basically run you through the gauntlet of a number of things to consider if you are monitoring your processors temperatures and trying to determine whether they are higher than they should be.
Perhaps that was a bit more information than you came for. So, with that in mind, lets take a step back and lets determine whether or not your CPU is running extremely hot.
If you have an Intel processor, thats actually a pretty easy task to do, as Intel provides the maximum operating temperatures of their processors on their website.
If you have an AMD processor, figuring out what the maximum operating temperature is is a bit more difficult. That is another scenario where you have to search and see what others are getting.
But, lets take a look at Intels maximum operating temperatures to give you some more insight on the matter.
TJunction (TJ Max) or Max Temperature
Intel defines TJunction (TJ Max) as the maximum temperature allowed at the processor die. When most modern processors hit their TJunction (TJ Max) or maximum temperature, the CPU will throttle and slow down so as to prevent the chip from going over that maximum temperature.
Up until the processor hits that maximum temperature, for the most part, it will run as expected (unless it runs at a level close to its TJ Max for extended periods of time.)
So, ultimately, if your processor is running close to its maximum allowed operating temperature, it is fine for the time being. Over the long run, it will wear down faster, but for the short term, you arent going to blow your processor (and your system) up if it is operating close to its maximum temperature.
However, if your processor is consistently operating near its maximum operating temperature while under load, that could be a sign that something is wrong.
The good news about an Intel processors maximum temperature is that, unlike determining a processors ideal idle and under-load temperatures, each Intel processor has a clearly defined maximum operating temperature that can be found on Intels website.
So, the good news is that, if you have an Intel CPU, you finally have a concrete number to work with.
Simply go to your CPUs specification sheet on the manufacturers website and check and see what your processors maximum operating temperature is.
For my iK, the TJunction (TJ Max) is degrees Celsius. That means that as long as my processor stays under degrees Celsius, it should be fine for the short term.
However, for the health of my processor and my system, Id prefer that my processor operated at temperatures far below that number.
Again, while getting close to that number is okay in a one-time situation, continually operating close to it is going to shorten the life of your processor.
So, perhaps the easiest way to tell if your Intel CPU is, in fact, running too hot, is to monitor how close it runs to the maximum operating temperature when it is under load.
The closer it runs to the maximum operating temp (on a consistent basis), the more cause for concern you should have. And, if its continually reaching levels close to the TJ Max, there is likely something wrong (whether that be an incorrectly installed CPU cooler, poor air flow, or old thermal paste, etc.)
AMDs Max Temps Arent Specificated
What if you have an AMD processor? How can you check and see if its operating at too high of a temperature?
Well, unfortunately, AMD doesnt provide a specific maximum operating temperature for their processors. If you want to see what I mean, Google Ryzen 5 X max temp.
What youll find is a bunch of people guessing what those processors maximum temperatures are, and nobody really knowing % for sure what number specific AMD CPUs will start to throttle at.
But there is typically a general consensus temperature range on when throttling will occur on a given AMD processor. And, so, after Googling to find that range (youll have to sort through forum posts and reviews and see what temperature levels others are seeing), you can use it in the same manner that you can use Intels TJ Max specification.
If your AMD CPU is consistently operating at temperatures near that maximum range, then there could possibly be something wrong.
How to Fix High CPU Temps
We have already discussed a few different ways that you can improve your processors temperatures. We outlined all of the different factors that contribute to what temperatures your processors cores run at.
So, now, Ill give you a quick list of ways that you can improve your CPUs operating temperatures, with some accompanying resources
- Re-install your CPU cooler
- Use better thermal paste
- Buy a better CPU cooler
- Buy a better case
- Reconfigure your case fans for better air flow
- Add more case fans
- Clean out your computer
- Delid your CPU (for extreme users who want high overclocks)
Applying any (or all) of these tips should help give you more optimal temperatures for your CPU.
If you have a laptop, your only real options are to get a laptop cooler or to get a new laptop.
Wrapping it Up: What Having Good CPU Temps Really Means
Let me finish this up by saying
For most users, there is no need to try and push your processor to operating at extremely low temperatures.
Yes, theoretically, the cooler your processors cores run, the better.
Where having really good CPU core temperatures matters most is when you are planning on overclocking your processor. In the simplest of definitions, the cooler you can get your processor to run, the higher you can overclock it.
If you have no plan on overclocking your processor, then as long as your processor runs at an average (or even slightly above average) temperature while under load, then thats completely fine.
Though, you might not get as many years out of your system as someone who uses better cooling. But, since youll likely upgrade your system within years, you probably wont miss the added lifespan that better cooling offers.
So, in other words, if you landed on this article because you are freaking out that your iK (as an example) is running at degrees Celsius when playing PUBG, and Joe Bob the extreme PC builders CPU is at degrees Celsius when running PUBG, that doesnt mean that there is anything wrong with your system.
It just means that Joe Bob the extreme PC builder has taken their cooling to the well extreme. And, your normal temperature only looks hot in comparison, when, in fact, it is actually fine.
So, the bottom line is that you shouldnt freak out if your CPUs core temps arent extremely low. You should only freak out if your CPUs core temps are extremely high. And, with the information in this guide, I think youll have a better idea of how to figure that out.

Spikes of just over 90c and a max "common" temp of around 80c would be ok. Most overclockers are happy if they hit mid 80's running aida64, so those values I mentioned are conservative.
You can improve the temps some by having a higher airflow in to the case. This pushes the air out the path of least resistance, which in your case would be the radiator.
https://siliconlottery.com/ offers a delidding service which will drop your temps down.
Consider if you got the thermal paste right. Your temps are not a problem, so you probably got it right. But too much thermal paste is such a common mistake. I recently swapped from Arctic Silver to Kryonaut and that dropped it around 2 degrees.
1. Would you suggest I delid my CPU? I wouldn't have a problem doing it at all and would actually want to so I could OC higherif it didn't void my warranty But it does. What would you do if you were in my shoes?
2. So just for clarity. As long as I only see random spikes just over 90C, and at average im from C, I should be safe; correct? This should allow my CPU to last the 5 years I would want it to last?
3. Would I be able to send you a picture of my computer so you could tell me what the optimal fan configuration should be? I use ALL Noctua RPM PWM Industrial Fans and I'm not AT ALLafraid to run them at RPM 24/7 while I'm gaming because I do not care about noise AT ALL.
4. I know the Noctua NF-F12 is the Static Pressure Fan that should be used on radiators. However, I looked for an hour and I couldn't find a mm version of them. Only the mm version. Do they make these, and if so, could you send me a link?
And by the way, thank you so much for all the help so far.
Idle, Load and Max CPU Temperatures
What is a normal and safe CPU temperature range? Join us as we reveal Intel and AMD CPU temps during idle, normal and maximum load.
All temperatures listed on this page are for CPUs running at default (non-overclocked) speeds with stock coolers. To give you a better understanding of Intel and AMD CPU operating temps, we have included their temperatures at different usage levels:
- Idle Temperature - Computer idling at Windows desktop (no open windows or programs)
- Load Temperature - Computer under heavy use (heavy gaming, video editing, stress tests)
- Max Temperature - Highest safe CPU temperature (as stated by Intel or AMD)
Running your CPU near its max temperature for long periods will affect its performance and may shorten its lifespan. Once most CPUs hit 90 to °C, they will begin throttling (lowering their clock speeds) to avoid overheating. If temperatures rise further, the CPU will shut itself down to avoid permanent damage.
We recommend that you measure the temperatures for your own CPU and compare them with the values below - Click here to learn how to check CPU temps.

Other Factors That Affect Your CPU Temperature Range
Even with default clock speeds and stock coolers, there are still other factors that will affect your normal CPU temperature:
Ambient room temperatures can affect CPU temps by 5 to 10°C. As a rough gauge, 1°C rise in room temperature = 1 to °C rise in CPU temps. That's why experienced hardware reviewers and overclockers will factor in their ambient room temperature when taking temperature readings.
Computer Case Cooling
A CPU can run 8 to 10°C cooler in a spacious computer case with excellent ventilation vs a small, cramped case filled with dust bunnies. Here's how to check if your computer case is doing a proper job of keeping the CPU cool:
Measure the temperature of your CPU with its side panels removed (see image below):
Close the computer case (put back the side panels) and check its temperature again. If the average CPU temperatures rises more than 5°C when the case is closed, then your computer case lacks adequate cooling. You'll need to organize your computer cables, get more (or better) case fans and consider using a modular power supply to minimize clutter.
We know what you're probably thinking at this point "Why don't I just leave the side panels open or go all out for an open air rig?"
While this method will indeed lower temperatures in the short run, dust will quickly clog up your heat sinks and fans (leading to even high temps than before). Therefore it only works if you're prepared to clean your heat sinks and fans every two to four weeks. In fact, a good computer case with directed air flow and pressure difference will run even cooler when closed.
CPU Build Quality
Due to their complex manufacturing process, even CPUs of the same model and batch can have notable differences in quality. While defective CPUs are discarded and inferior ones are rebadged, there is still a quality difference in those that make it past factory inspections.
Getting a high quality CPU from a store is a matter of luck (which is why overclockers get so excited when they chance upon a CPU of exceptional quality). All things being equal, a high quality CPU will run cooler and overclock better than a typical sample.
