[SOLVED] CPU usage low CPU fan and frequency high

[Masonwhite]

New build and not sure why my cpu usage is under 20% and yet my cou fan is 90-100% and frequency is very high. Any recommendations on why this is happening?

Until you list your parts it would be just wild guessing that wouldn't be of any help. Also under which circumstances does it happen ?

What are your temps looking like on the CPU? Don't know? Download this utility and it will let you know:

It happens playing games usually in balanced mode not extreme performance and temps 55-65.

What do you mean when you say:

usually in balanced mode not extreme performance

Do you mean the windows power plan balanced and high? I think your issue is that you need to set a custom fan curve so that the CPU temps dont cause the fans to go towards 90-100% when its only at 55-65 c temperature.

This is probably because 1 or 2 cores are been taxed at 100%, thats why you see the CPU fan at 90~100% RPM. Your gaming is most likely using only 1 or 2 cores. Those cores are boosting really high and so the temp from those needs to be kept under control and so -> CPU fan goes to 90~100% speed.

What I meant with that it is with the MSI motherboard and CPU you can have profiles of silent, balanced, or extreme performance where the CPU and fan will run at different levels.

Is there any way to avoid boosting 1 or 2 cores high and instead keeping all at relative same level?

Nop, this is something that its related to how the game was writen in the first place.
Newer, and more demanding games are usually able to use as many cores and threads a CPU can have (once again as long as the developers wrote and desingned the game this way, which is usually the case lately), but some more "modest" games and/or old ones, only use between 1 ~ 4 cores, maybe 6 but thats it.
Your CPU comes with 8 physical cores and 16 threads (this last number is equal to the total of physical cores = 8 + the amount of "logical" threads available through the SMT function = 8 logical threads).

Its a little bit more complicated than that but I tried to keep it simple, I hope it helps.
