Intel i9 10850K is too hot.

[Kai-]

I bought my PC in June 2021. After 3-4 months my CPU started running so hot. I disabled boosts (I mean my CPU is working at 3.6GHz), ASUS Multi Core Enhancement etc. but it didn't work. It works 50-55C in idle (my room is like 20-25C) and 90+C while playing CS:GO or Valorant or any game. I don't know what should I do. I need help, please.

Thank you.

NOTE : I don't know so much thing about PC parts.

Motherboard :ASUS PRIME Z590-P, Z590, DDR4, SOCKET 1200 ATX

Graphic Card (idk if you need) : ZOTAC GTX 3070Ti AMP HOLO 8GB, GDDR6X

Cooler : MSI MAG CORELIQUID 360R 360mm

Computer Case : Cooler Master Mastercase H500 2x200mm ARGB MidTower Case

Improper applicatation of thermal paste and/or incorrect installation of fan/cooler.

Re-do those, and update your bios.

If you do not know how, take it to a repair shop.

[Kai-]

I already updated the BIOS. It's still same. 

My thermal paste is not dry so I think remove all the paste can be a bit hard. Should I do this?

I don't know If there is a problem with my cooler/fan so if there is anything I can do except cooler/fan I need to try and if that thing doesn't work, I can go to the repair shop for my cooler/fan.

My English is not so good, sorry for that too.

Kai-, Thank you for posting in the Intel® Communities Support.

The T-junction of the Intel® Core™ i9-10850K processor is 100°C, any temperature results equal to or below that value is considered normal and expected for this unit, especially while playing games which is a high intensive task, even though you are using a dedicated graphics card:

In order to rule out a possible hardware problem with the processor itself, please install and run the Intel® Processor Diagnostic Tool, it does an overall test on the unit and if it passes the test it means it is working properly:

Also, in the link below you will find additional details about overheating symptoms on Intel® processors:

It passed all tests. Thanks for your answer. I've relaxed a bit. Have a nice day!

If your idle temperature is above, say, 55c, then yes, I think you should redo your TIM (thermal paste). After removing cooling solution from processor, use dry cloth to thoroughly remove old paste from the top surface of the processor and the bottom surface of the heatsink. Apply new paste (I use Arctic Silver 5) to top surface of processor and reinstall heatsink. Here is reasonably good summary of what to do: https://www.microsi.com/blog/applying-thermal-paste-4-things-you-need-to-know/.

Hope this helps,

I'll try this. I bought Arctic too and I'm waiting for the shipping. I hope it works... Thank you.

Kai-, You are very welcome, thank you very much for your response.

"It passed all tests", perfect, excellent, now we can make sure and rule out a possible hardware issue with the processor itself.

Any other inquiries, do not hesitate to contact us again.

N. Scott Pearson, Thank you very much for your comments and suggestions.

One thing worth mentioning that could be causing this unwanted CPU heat, make sure none of your liquid cooling lines are touching anything hot like your GPU for instance. If the cooling lines are touching your hot GPU it will heat up the liquid that is supposed to be as cool as possible before it gets recycled to your CPU to cool it off.

Another thing you may want to check if you yourself didn't build the computer is to make sure there is nothing foreign in between your CPU heatsink and the CPU. Of course you want thermal paste between these two but you don't want anything that shouldn't be there like a sticker or something left from the factory. Any foreign object between the two could definitely cause your CPU to heat up.

[Kai-]

I checked but there is only thermal paste between heatsink and CPU; and liquid cooling lines are "free", they are not touching anything. 

Anyway, thank you for your answer.

[n_scott_pearson]

It is not a good practice to separate the heatsink (or, in the LQC case, the water block) from the processor without also replacing the TIM (heatsink paste). Rarely would the result be anything but poorer operation and higher temperatures.

If you did replace it, great. Otherwise,...

[Kai-]

No I didn't.... My new thermal paste will arrive tomorrow I'm still waiting for it.

But, even I didn't change anything, my temps are better than before. According to HWMonitor my idle temps are between 37-43C and in game temps are between 70-80. I really don't know why, I think it is so strange...

Tomorrow or next day, I'll apply new thermal paste and I'll check the temps again. For now, everything seems good. 
Thanks a lot for your answer.

[n_scott_pearson]

Hhmmm, this usually means that the heatsink (or water block) was incorrectly installed previously (possibilities include too much thermal paste, poorly spread thermal paste, heatsink (or water block) improperly attached to processor, etc.). Whatever you have done has indeed improved things - but you should still replace the existing thermal paste when the new thermal paste arrives.

...S

[Kai-]

I replaced thermal paste with the new one. Now, on idle its 35C but still 85-90C while playing video games. Is there anything I can do about it? Or should I buy new cpu cooler?

[computeman]

Are all your fan's are pushing air in the right direction? Intake fan pushing air into case and exhaust fan's pushing the air out.

[n_scott_pearson]

Provided temperatures are in the 80's and not spending any significant time (i.e., only occasional short-duration spikes) in the 90's, then you are within normal operating parameters. If you want to lower the temperature even more when under load, then you will need to use a better cooling system.

[Kai-]

No, I just don't want to damage the CPU. As I said, I don't know much about computer parts so, sorry for repeated questions.

Thanks all of your support.
