CPU Fan Issues

Didn't know where to put this, so i've put it somewhere else too.

Hi guys.

I am having some issues with my CPU fan.

I have an MSI 760gm-E51 FX motherboard, and for some reason it seems like my cpu fan is running at a constant 100% (very noisy)

The ONLY way i have been able to change this (including enabling smart fan and disabling etc in the bios) was by turning down PWM1 in Speedfan 4.49.

After turning the fan down, under idle my temps dont change (they always hover around 44-47 degrees C )

Even the automatic fan speed in speedfan doesnt do anything, nor does the fan utility in AMD overdrive (even by switching the fan control to manual, it does nothing)

Id like my fan speed to only ramp up when it needs to, any ideas?

Thanks in advance.

P.S Buying a new cooler isn't an option at the moment

Also, seem to have some conflicting temp readings. (not overclocked)

It is the "right hand" PWM1 that i change to step down cpu fan, the left one doesnt seem to do anything.

UPDATE: when i turned it on this morning, it stayed at the level speed fan left it at (i think) and sped up when it got warm, but didnt slow down again (had to do it in speed fan again)

Maybe it's a mobo thing. The MSI 760gm-E51 is a budget mobo so odd fan control would be an issue.

Have you tried looking in the BIOs and look for fan speed control options? something like PWN.
 
Yep, tried looking through the bios. Regardless of motherboard, it should have at least basic fan control surely? not just 100% all the time. That still doesnt explain why other software cant control fans

Yeah the setting that controlled your fan speed was call "CPU Smart FAN target"

Not really. While fan control does exists on most mobos from 2006 and onwards, a lot of times the fan control setup weren't that good. In this case, since you have stated that you have enabled CPU Smart FAN target, it may mean you might have gotten a mobo with not-so-good fan control. Then again, it might be due to your FX CPU since those do run a bit hotter than past AMD CPUs and so your mobo thinks the fan needs to be kept on at all times.

With that said, clean your heatsink, clean your case, and reapply thermal paste if you can.

Some software require specific drivers and additional firmware information in order to be able to access
