Athlon X3 fan running a little high?

post #1 of 6
Thread Starter 
So, I built my parents their rig(which I am always tweaking) and the fan/heatsink was running, up until 5 minutes go, maxed out around 5000 rpm. I mounted my 965's stock heatsink when I built it, which is a little beefier than the 435's x3 stock.
Went into bios, and put the setting onto "performance". I picked that out of "quiet" and some other option..but the fan right now is running around 4,000 rpm. It doesn't really bother me, but I'd always suspect that with the chip running around 28c right now, the fan wouldn't be spinning near has high.

Assuming it is an Asus board,
try the "optimal" setting if you have it.
That will run slower and ramp up/down with cpu temps.

Go into the BIOS and enable the Cool 'n' Quiet option and C1E also, and check around for the CPU fan setting and set to AUTO or by tempature

I have the same problem and have read a few others with similar issues too.I have to use speedfan to reduce the speed.Also my gigabyte board set the vcore by default to 1.425v which i reduced to 1.3 and the temps dropped 20 degrees C and fan slows down a bit.

I stay in a hot place so fan slows down with the A.C on.

Can you check your vcore?

It is a Biostar 880G board. Vcore is 1.3 I believe....

Which Gigabyte board are you using? I'm using the 880GM-UD2H, and it is set at 1.400-1.425 on AUTO. I had to manually lower it to 1.38 for my 965BE. I'm betting all of those boards automatically set to 1.4.....

Mine is a 785 gm us2h. Vcore of 1.4 seems way too high and and o.1 v reduction brought down my idle temps by 20 degrees.I can run it at 1.2 v also which seems to also run fine.
