Hello,

2 days ago i switched to this cpu and used my old one - arctic cooling pro esports red duo.
I've been told that this cooler will be enough for this cpu, but in real time gaming the cpu actually going up to 100c and the computer shuts down after a short time in games.

To save you from asking - I've done it several times(put it with new thermal paste) , it looks like the cooler works as it's supposed to, but even on max rpm, the cpu goes up to 100c.

Do you think mybe i did something else wrong, or the cooler isn't simply good enough?

You'll only see that in 2 scenarios:
-Single threaded, light tasks.
-Keeping Thermal Velocity Boost active, aka, keeping thermals below 70C.

That isn't the problem though.
These are hot chips, but Intel mitigated this with conservative power limits... but they're a little too conservative.
Raising/removing those power limits shows just where Intel got by squeezing more and more speed out of the same process node...


TL; DR: No.
280mm. Preferably 360mm.

Too many words in this, I think. I'm going to assume you're referring to this one: https://www.arctic.ac/en/Freezer-34-eSports-DUO/ACFRE00060A
I'm going to trust you mounted the cooler correctly.
1)That kind of cooler is designed to handle up to - but not exactly - some 200w of heat.

2)On Intel stock settings, an 10900KF can easily exceed what the Freezer 34 is designed for. FYI, 10th gen power tables below:

View: https://imgur.com/YwqWtBb

Power limit 1 is what's allowed across all threads at the cpu's base frequency.
Power limit 2 is what's allowed regarding Turbo Boost.
Tau is the duration PL2 is allowed to run, after which it is forced back down to PL1, and depending on the kind of load:
-it will either sit at PL1 until the work is finished; generally, heavy, steady tasks
-if the load is constantly changing, PL1 'breaks' will be very short, and PL2 will be available pretty much all the time.

There's also the i9's exclusive Thermal Velocity Boost, but that has a limit of 70C.

3)Some motherboards don't follow Intel stock operation out of the box, opting for performance tweaks - but that equates to power consumption and higher operating thermals
I can't tell you which boards do this. The best thing to do here is to monitor clocks and power consumption yourself.

4)LGA 1200 = LGA 115x. No difference in socket sizes.

The measurements are in delta T over ambient... which means:
If that test was done in a 20C room, the Freezer 34 was hitting 85.5C and 96.9C respectively. But this was a worst case scenario: OC'ed 5930K(6c/12t) in Prime 95, Small FFT, with AVX on.

LGA 1200 and LGA115x are the exact same socket mount size for coolers.


I haven't retested the Arctic 34 eSports DUO cooler on our overclocked i9-10850k.

However, stock settings, I don't see why there would be an issue, so it sounds like an incorrect mount or there is an issue elsewhere.



Edit: I did retest it, just checked my data.

i9-10850k, all 10 cores at 4.60ghz -

Arctic Freezer 34 eSports DUO:
100%: 55.2 C (above 23.7C ambient)
50%: 62.6C (above 23.2C ambient)

So, something is wrong for you.

You are all probably right, i need to double check if the cooler sits tight enough on the cpu i think

itaym178,

You're attempting to use a mid-range cooler on a very high-end processor ... so of course it runs too hot.

The Arctic 34 eSports DUO is a single tower 2 fan cooler with 4 direct touch heat pipes. Although the heat pipes are arranged in the cooling fins differently the Cooler Master Master Air MA410M, both are still single tower 2 fan coolers with 4 direct touch heat pipes, which is essentially a Hyper 212 EVO with a 2nd fan.

The i9-10900KF is an i9-10900K without an Integrated Graphics Processor Unit (IGPU). The i9-10900K(F) is a 10 core 20 thread blast furnace which demands, at minimum, the best of the high-end air coolers, such as the Noctua NH-D15, which is a dual tower cooler with 6 heat pipes ... or ... a 280mm AIO ... or preferably a 360mm AIO or a custom loop.

Bottom line? You need to upgrade the cooler.

What is the make/model of your case.
What is the fan arrangement?
Any cooler needs an ample source of fresh air to let it do it's job.

Run HWmonitor
It will give your current, minimum and maximum cpu temperatures.
Look at the minimum.
If your cooler is mounted well and running properly, then I would expect to see idle or minimum temperatures in the range of 10-15c. over ambient.

A common mistake is to use too much paste which acts as an insulator.

Your processor, even at stock will turbo up quite high if the load is low and your cooling is effective.
With such a nice processor, I think you should look at a cooler upgrade.
My pick would be a noctua NH-D15s.

Go to the noctua web site and access their motherboard compatibility section.
It will tell you what coolers are compatible, and what the overclock potential is.

Update - i doubled checked the cooler, put a thermal paste again, double checked the screws and everything sits as it is supposed to. The airflow is good and even on full speed the cpu hits 100c

So how do you explain the other comments that said the cooler is good enough?

Anyway i thought i needed to upgrade, so i ordered the asus rog strix lc 240, is it good enough?

My case is antec nx600, im aware that this case is not that good for airflow, and i dont think it is the thermal paste because i did it exactly as it says in the arctic's manual.

Even though i dont have a good case, i dont think it is suppose to go up tp 100c because with my old cpu( 9700k ) I've reached to 72c in games with this cooler

Hold on... is it like that, even in bios? Like, is it over 50C in bios?
There's definitely a mounting problem if it is.

It is over 50 in the bios it's really okward ....anyway, i dont have the box or instructions for this cooler so i followed a youtube video...thats all i have.

I bpught the asus rog strix lc 240 i think it will be more than enough am i right?

Something isn't right...
That is a hot cpu, but if it's just running in bios and on stock settings, it shouldn't be that high...
Perhaps the back plate wasn't installed correctly?
Fans not setup correctly? Facing the wrong way, or fighting against each other?
I want to believe that the video told you how to install the cooler correctly, but...

Intel stock operation, and nothing more... though anything with AVX/AVX2 may still be a slap in the face.

I just nned to know if it is enough for gaming in case the cpu goes up to 5.3ghz

On default CPU/BIOS settings, that cooler should be 'OK', but if heavy usage is going to be maintained, something better should be considered.

These i9's get really hot, depending on how they are setup and environment they are used in. Read: need for great airflow.

This is especially true if you get to all-core overclocking and static frequency instead of default options to fluctuate.

For example, at 5.0Ghz across 10 cores on the 10850k, it was starting to really push larger AIOs where core temps were rather high, especially at lower fan speeds, which is why I had to resort to a lower clock speed of 4.6Ghz so that smaller coolers wouldn't melt....and even then, some coolers throttled CPU at 50% fan speeds.

Nails on the chalkboard....that voice.

I think OP didn't have anything set beyond defaults, but I still agree with a better cooling being the best option, but I haven't seen temps like that on any tests I've done with the 10850k unless it was 5ghz across all 10 cores.

The 10900kf and 10850k are pretty similar parts with the 10900kf just a bit higher in terms of stock clock and turbo.


Question:

Does the CPU cool down immediately when load is removed and allowed to return to idle, or is it a bit sluggish for up to 10 seconds? Ideally, you should see a drop of 20-30C almost immediately, depending on idle/load and ambient temps.

What does the CPU idle at on the desktop?
Are you using any reporting software to see temps?

One last note:

Depending on which EXACT Arctic Freezer cooler you are using, I did get 2 bad samples from Arctic at one point where each had one or more bad heatpipes. When I shipped back to Arctic after testing, they said their lab confirmed that each of the coolers had at least one bad/non-working heatpipe, possibly more than 1. This was on a couple of the older '33' models of coolers, but did not have this happen on more recent ones. This would not be as apparent on lower TDP CPUs but certainly are seen when greater thermal loads are present.
