Question 11900k idle power problem, cant go below like 50w even at 4ghz

[Paulie walnuts1888]

why is 11th gen power draw so horrible lol? 10600k at 4ghz could idle below 1w, why tf the 11900k at even 3500 mhz can not go below 11 watts doing literally nothing. pretty insane. putting 10600k back in i think

11900K was/is not known for being cool running or easy to cool, although most folks were more interested in keeping temps manageable at load, vice measuring their min power draw under no load as indicated by HWmonitor or similar.

Check the BIOS to see if the low power C states are enabled. This can help reduce idle temperatures significantly. You can use ThrottleStop to see what core and package C states your CPU is using when your computer is idle at the desktop with nothing besides ThrottleStop open.

Are your cores averaging 99% in the C7 state like they should be? Many users have piles of stuff running in the background so the CPU is a lot busier than they realize. One poorly written app can create a lot of excess power consumption and excess heat.

How are you measuring power consumption? The power consumption data coming from Intel CPUs is only an estimation. In some situations, this data is not accurate at all. Avoid using this data to compare different CPUs, especially ones from different generations.

Use HWiNFO to see what your VCore voltage is. Using default settings can set the CPU voltage much higher than it needs to be. This will increase power consumption and heat.

Do some testing. If your idle C0% is much higher than 0,5%, look in the Task Manager Details tab and find out what is running on your computer. Windows can be very lean when it is properly setup.

So i just put 10600k back in and i am back down to 1 watt power use with the exact same bios current/c state/voltage settings, 11900k was not getting below 12w lmao

ur on 10900k?

ur on 10900k?

10850K which is the same CPU die as a 10900K. It is slightly overclocked to 5.0 GHz all core.

the exact same

The exact same does not mean anything. The BIOS might setup different CPU models differently. You need to check C state activity and VCore voltage for both processors.

11900k was not getting below 12w

Intel power consumption data is a meaningless number. Go buy a Kill-a-Watt meter or something similar to see if there is any difference in actual power coming from the wall when your computer is idle at the desktop.

yea bruh u gtta use a rocket lake we on that mega efficient per watt comet lake rocket lake a diff <Mod Edit> crazy dawg

i could tell the heat was real judging by my room temp lol
