Help!!! CPU Fan not going over 2200...any ideas?

[r¡sê ºƒ çhaös]

Any ideas on this would be most appreciated...
My CPU Fan isn't going over 2200 RPMs and the CPU is going into the Red Zone... normally the Fan should be well over 3000-3500 RPMs. Fan Control(power saving) is OFF in the BIOS... unfortunately my bios /main board doesn't allow for further adjustments/thresholds etc.

I am just wondering if anyone has experienced this and knows of a solution or where the problem could be coming from.

So, if you connect it with the adapter to a 12v line, it should run full speed.

Read first, and correct me if i am wrong :D

I've got Intel Desktop Utilities and it shows the voltage etc so there is no problem with the power its recieving. My BIOS has a power saver feature called "Fan Control" which limits it and is a definite no no for any gamer. When Fan Control is on it limits the fan to like 1200 RPM's max. So its definitely off. Normally the Fan has always worked well over 3000 RPMs and it made a big difference in keeping the CPU out of the red zone etc. Now it won't go past 2200 and its well into the Red Zone... so something is wrong for sure.

The 12 volt meters look normal, like at 12.250

If your processor is overheating, the you may need to remove the fan and replace the thermal paste and reset the fan. The paste could be old (or non-existant) or the heat sink could have become mis-aligned.

You fan could also be going and needs replacement, cleaning or checked for abstructions (ie. wire touching it).

If the fan speed is slower than usual, replacing of paste would not make it faster.

I'm thinking of the over all heat issue, not just fan speed.

My fan never exceeds 2k rpm, 3000-3500 is it's max rpm. Plugged into the MB too, not a direct PSU connection. If a fan is constantly at max, then there are other issues.

Yes. Half speed, lower cooling. Quiet obvious.

Unless one knows better.

This is what I figured out. My video card just went bad and I am getting my new one in a few days, its on its way. In the meantime I was playing some old titles that don't require a video card, i.e. from 2003 etc. I then figured I'd install my motherboard Intel Express Graphics since at least its a 3D Accelerator. This is what is happening and I'm not sure if this is supposed to work like this or what. After installing the Intel Express Graphics (from the motherboard CD drivers etc that came with it), and then going to play a game, I see two things now
1) when playing a game, I get two big processes in Task Manager, one of course being the game,( i.e. unreal2004.exe) etc, and the other is, strangely enough, the explorer.exe (which is Windows Explorer), that is suddenly using like 50% of the processor along with the game.. so I'm assuming this is maybe how the Intel Express Graphics works (big "if" there). The second thing is now, the CPU fan no longer goes into its definitive 'airplane jet take off mode'... I think everyone knows what that means.. i.e. when the fan goes up to and over 3000 RPMS and it gets loud. And of course I'm watching the processor when I'm playing these games and its going really high into the red zone, i.e. where the Fan should definitely be kicking in. So I'm wondeirng if this isn't some kind of power issue , i.e. where as before the power from the two 6 pin connectors were powering the video card (it was big 8800GTX from several years back) but now maybe there isn't enough motherboard power to bring that fan into overdrive since its being utilized for graphics? And I'm thinking this is some kind of setting or something that was installed with the Intel Express Graphics? Any ideas or thoughts highly appreciated.

Correct solution right here. Not enough power to the MB is a possibility, easy to check but a bad fan is most likely and easiest to check. I would replace that thermal paste no matter what.

Right but the problem is my Intel Desktop Utilities is detecting the CPU going into the Red and that also controls the Fan and the fan is no longer doing its 'jet take off' mode thing where it gets loud. I.e its not even attempting it. If the CPU was getting hot from bad thermal grease etc, woudln't the Fan still go into its loud/high mode since its being detected as getting hot? And its not even attempting it.. its not like its getting loud but the fan just isn't getting the RPM's that it did... its not even going into that loud mode that I can easily recognize.

Most likely it would. The reason I would replace the thermal paste is because it has already overheated and the paste is likely bad by now. It does not last forever and it is a good preventative measure.

Like I said, the most likely thing is the fan. I replace CPU fans on a regular basis, the same with case fans and video card fans. They all go bad eventually. None of them last forever.

But if the fan went bad wouldn't I still hear that distinctive extremely loud volume increase still and maybe the fan just wouldn't get as high as it used to? Or is it something like when the fan goes bad, that entire mode just fizzles out and its unable to even accept that command?

The fan reaching MAX speed is what is making that noise. If the fan is bad and dragging it can not reach max speed and you will not hear the noise. Why are you trying to make this complicated when it is not?

I'm pretty sure it isn't a hardware issue, but some kind of power management issue. I'm reinstalling everything I'll be happy to let you know if I was right if your interested for your own knowledge. Thanks for your help.

have you tried re-installing the intel program your running that controls all of this? I had ASUS program like it that out of the blue the other month it turned off all my fans that were connected to motherboard fan headers, i removed said program and re-installed it and all is good again.

I went to update to the latest Intel Desktop Utilities and now suddenly it no longer works because the service is not running. I go to start the service in services.msc and it times out saying it failed to start in a timely fashion... unbelievable. I then restored the system back to before the utility update and the service still fails to start even for the prior Desktop utilities. Seems intel is pretty intent on ensuring that I need to get a new motherboards/processor one way or another. Going to completely reinstall everything and I have a feeling it will all work again.

get an aftermarket cooler

2200rpm sounds like an amd cpu stock fan
if its noisy at 2000+ rpm its bushing could be going bad

depending on teh cpu, a tx3 or 212evo will cool it nicely at stock speeds, or allow for a decent overclock
