Cpu fan running at full speed constantly.

kol12 · Mar 21, 2015

My cpu fan is running at almost full speed constantly. I have never seen this happen before.
Has the fan sensor or something died?

I'm pretty sure this happened right after getting a Mantle Api error crash from within a game.
Asus q fan still seems to be able to control the fan but even when using a q fan profile then running a game the cpu fan ramps right up.

Help whats wrong?

Have you checked your CPU temps?

kol12 · Mar 21, 2015

Yes they seem normal..

kol12 · Mar 21, 2015

actually I'm not sure, I just checked core temp and they quite high. Have disabled q fan and fan has ramped up again..

What does core temp say your temps are?

Also, download HWMonitor, and tell me what it says your temps are.

temps are now dropping but fan still running about 2000 + rpm..

kol12 · Mar 21, 2015

Core temp 40 40 36 38

kol12 · Mar 21, 2015

HW Monitor same temps.

Ok, that seems fine. Maybe download HWMonitor just to make sure it is reading close to the same.

kol12 · Mar 21, 2015

cpu fan 2445 rpm!

kol12 · Mar 21, 2015

Yes HW Monitor same temps.

kol12 :

Ok then. I would say your temps are fine.

I would guess that either your sensor on the motherboard that controls the CPU fan speed has gone, or there is something wrong with your CPU cooler.

Maybe do something on your computer that is CPU intensive and see if temps shoot up past 70C.

kol12 · Mar 21, 2015

Ok. What next?

kol12 · Mar 21, 2015

running prime95 not climbing past 60 very quickly. Up to 67 now.

kol12 · Mar 21, 2015

I will be back soon.

Have you rebooted the computer after the error occurred?

kol12 · Mar 21, 2015

yes..

kol12 · Mar 21, 2015

If I set asus q fan to optimal the fan speed drops to 1562rpm but cpu temps are going to 45.

kol12 · Mar 21, 2015

somethings definitely wrong.

Cpu fan running at full speed constantly.
