Hi,

I've just built a new pc with intel i7 10700k and Mag z490 tomahawk motherboard.
Running with auto settings in UEFI, motherboard uses different settings than intel recommendations for this CPU.
I want to try intel specs to lower down temperatures a bit since I don't need additional performance right now.
I disabled "Enhanced turbo" and set PL1=125 and PL2=229. Is it enough or are there any other changes needed?

Thanks.

Lower CPU ratio to bring down your CPU freq
I would choose to upgrade CPU cooler instead of lowering CPU frequency to cool it downo_O

Thanks for suggestion but I don't want to lower CPU frequency but only turn off (at least for now) all the default "auto oc" features applied by motherboard.
I have scythe fuma 2 cooler which should handle stock 10700k. Temps are quite ok but seems a bit higher at load than I expected based on reviews so I thought that maybe there are other less obvious uefi settings which I missed.

Hi
What are your temps under full load?
If auto oc applies higher frequencies, then it means that there's still headroom in terms of temps.

Hi

If auto oc applies higher frequencies, then it means that there's still headroom in terms of temps.
With power limits enabled temps aren't that bad - during single cinebench r20 run I got max 72-74C (depending on ambient temp), if I run it multiple times it goes up to like 78C then boost drops from 4.7GHz to 4.5 GHz what lowers temps (power limit kicks in as I understand).
While gaming it rather stays below 65, BFV peaking 70 - I'm gpu limited so cpu usage isn't very high though.
Idle temps are good 30-32C.

I was wondering if there isn't any other auto "overvoltage" feature which is ramping up core temp?

70, 80 degree is not extreme temperature for CPU, it can easily go that high under loading. Honestly speaking, if you don't your CPU to go "turbo", why would you even bother buying a rather high tier CPU. The main problem now is your CPU fan is not strong enough to deal with your CPU, locking CPU performance imo is not a good way to work your situation out :shocked: what kinda CPU cooler you're using right now? if you can afford a 400 dollars CPU why not upgrade your CPU fan?? just my 2 cents!

Thanks you all for help but I'm afraid that you misunderstood my initial question and discussion went off to temperatures problem but it wasn't my intention.

I don't want to downclock cpu but rather use it (for now) within intel guidelines with default turbo and power limits behaviour - as far as I know only Asus boards do it on auto settings (there are few articles about it already).
"Enhanced turbo" feature with disabled power limits causes core overvoltage and increases temps and power consumption above specification.
It's hard to know if I'm running stock if mobo applies OC on "auto" out of the box settings. There should be at least some info in manual.

I may try to manually OC in future and upgrade cooler (fuma 2 is considered as rather good air cooler...), case etc. if really needed.

Normally automatic OC is applied with Game Boost if you enable it.
What you are seeing appears to be normal behaviour for Intel turbo boost.
