Cooling 12900k

[MCFC_ANDY]

having issues keeping it from throttling under load when benchmarking with cinebench 2024 with PL removed, im hitting 105.
ive got 2 240mm AIO, both decent but neither can keep it cool. a DeepCool LE520 and Arctic Liquid Freezer II.

could getting one of those Thermalright mounting frames maybe help, or does the 12900k need a minimum 280 aio

Contact frame if my first go to, it made a huge difference to my temps even on my 12700k on a custom loop. Use to sit in the mid 60's, now it sits in the mid to low 50's.

Your 240 aio should be more than enough tbh unless your motherboard is doing something weird and not enforcing limits and allowing more voltage to be pumped through.

cheers will try the contact frame to start with for sake of a tenner

Let us know how you get on.

What do you do with the PC? Most of the recent i7/i9 CPUs will reach silly temps in Cinebench when they're power unlimited even with great cooling.

 

[MCFC_ANDY]

will do, i just ordered one should be here in next few days

How many watts is it using ?

240.9w was max i believe on HWinfo i

Definitely shouldn't be seeing those kind of temps, my 12700K overclocked hits around 230w and it sits around 75c full tilt on cinebench with an ambient of 21c.

Can you let me know how you get on please? If it helps I'll give one a go, its always nice to have lower temps!

will update thread when frame arrives n fitted, properly tues as off work

Yeah i noticed a drop on my 12900k using the frame. Can't remember exactly but was around 3 - 4c drop.

 

[MCFC_ANDY]

frame arrived earlier, somehow it was that quick, have installed temps have dropped by 10 degrees. still throttling a little at 95 degrees , but not as bad,

well yes... obviously. you have to tune power limits to what you do to hold boost. im going to assume you do work running cinebench 2024 all day. test in a way that suites the system you made

 

[MCFC_ANDY]

generally only a 10min run. just to see temps

 

[Wing-Man]

What is the system to be used for on a day to day basis?

Bench is good for feasting if stable. But the load is 90% of the time and unreal load.

If you game than game. And monitor. Also drop the PL limits to about 10% over what the max seen load is when you test.

Also defo under volt. At a minimum 0.0500v but most can do 0.1v

 

[MCFC_ANDY]

just gaming, just wanted see the 12900k stretch its legs, no issues gaming, temps fine, just being being inquisitive

 

[Wing-Man]

Even in games you should still under volt a little.

 

[MCFC_ANDY]

ok cheers for that

Good to know, very similar to my results with the contact frame. It's well worth having for the sake of a few quid.
