Any ideas on this would be most appreciated…
My computer 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. This is recent as I know for a fact that the fan regularly operated over 3000 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. Searching around hasn’t found anything that anyone knows of.
It’s either the fan or the power supply that feeds it. Most likely it’s the fan. Have you opened the computer up and looked at it? The first thing to look for is pet hair or other types of dust and debris clogging up the fan and slowing it down. If you’ve cleaned the fan out and it still runs slow then it could be the bearings in the fan. Check the blades to make sure that they aren’t cracked and that there is no damage that is causing the fan to spin unbalanced (which will also slow it down considerably). If you are handy with a voltmeter you can use that to check the fan’s supply voltage.
Let’s start with the basics. What OS are you running? And what fan control software are you using? How old is the fan? How clean are the fan and heatsink? Is the fan control cable plugged in correctly?
I have enough machines that I really should know this but I’m not sure. I think that normally fan speed is either maxed out or determined by CPU temperature which is based on what is reported by the bios. However I’ve run into this problem with engineering samples of CPU’s and perfectly good motherboards but it was the other way around. The temp being reported was dangerously high - over 90C - and the fans spun up to sound like jets on take off.
The utility that most overclockers use, or at least used to use, is speedfan by Almico. I’m pretty sure it’s still a free utility, but be careful. IIRC it will let you manually control the fan speed an might be of some use in troubleshooting the problem.
