I was overclocking my 3.0E Prescott 20% to 3.6GHZ and then my fans started dying. My CPU fan went from 3700rpm to 2280rpm and my 120mm rear case fan dropped from 1800 to 1100. I reverted back to original setting and they are still underpowered...any thoughts as to why this happened and how to correct it?

Underclocker

Check your that BIOS fan speed control settings aren't set to automatically lower speeds according to temperatures.

I don't see any fan control setting other than the low temp that ranges from 11/16 to 15/16 @ idle temp. All the way up it is still way low and the temps get high the fan doesn't spin any faster.

Your PSU is probably to weak to support your OC'ing. This seems like a voltage drain. Which could indicate you have pushing your PSU too far and is overloading.

Damn, but I've changed everything back to its default specs and it is still underpowereing the fans...Everything was fine before this...should i reset cmos to see if that does anything?

Aus_Karlos

You can try there's nothing to loose if you clear the Cmos as long as you dont have a custom configured Cmos setting.
Also download everest from my sig, it will tell you voltages and temps

I dont have anything custom configured so I'll try it. Also, I have ASUS Probe and my voltages look fine, but when i try it i'll postem.

Delsym

well the CMOS worked like a charm, but I would still like to achieve overclocking with this. Please read my system info and then help me determine my max...Note: I popped it up to 20% and the fans gave out:

Here are my specs @ idle!

Aus_Karlos

20% OC is a big jump. Up the FSB 5mhz, see if it boots and test with a program like Prime95. Continue to do so until it fails to boot or the fans slow down.

I would like to see those Voltages under load before you OC. Run a video converter or something that uses juice on your system. This will determine whether your PSU is capable of a stable OC.
Keep a close eye on the +12v and the +5v.

if I were you I would forget overclocking as long as you are using the thermaltake pure power


prescotts are not good overclockers you are not going to see an inprovement worth the risk you are going to run overclocking a cpu that runs so hot to begin with ???? 15% OC on a prescot is about all I would advise, especially when you are only using overclocking software which is the least desirable way to overclock >>>>> manual overclocking is far more productive


BTW: which cpu cooler are you running

Well I'm @ 10% because during a gaming session it crashed. I'm encoding a movie with highest priority. I'm using a Masscool Cooler

dai

your fan speeds are normal in the probes you posted

I reset the CMOS and it worked. Sorry if i didn't clearly state that.
