    CPU fan problem


    (sigh) ok then...

    I tried to turn my pc on this morning and all I got was a series of constant beeps, with the warning on screen '!CPUFAN NOT WORKING CORRECTLY' I unplugged my system whipped the back off to investigate, all seemed fine though just to be sure I gave the heatsing and fan a clean, it was a bit dusty.

    I plugged everything back in and still the same thing happened, so unplugged everything again took the back off left the power supply in and the noise from the fan was terrible. (I have noticed that the fan is getting nosier in the AM but after about 10-15 mins continues at normal sound levels.) I slackened the screws holding the fan down, turnedon and still the annoying beeps hmphh!

    After about 2hrs of messing and trying to slacken screws and tighten gradually to eliminate noise, I decide to try something, I took the fan from the cpu holding the fan in my fingers, switched the damned thing on only to hear the reasuring single bleep and the pc go to normal startup routine. I promptly switched the pc off and reattached the fan only to be back at sqaure one!!! could it be that by screwing the fan back on I am putting too much pressure on the CPU? Just seems very odd that when I remove the fan from the HS it goes into the normal routine, as soon as I reattach it goes into devil mode!

    Any help would be appreciated

    Was it working fine yesterday ? As you have noticed the fan getting louder at times, this could point to either an overheating problem or a faulty fan.


    I would replace the fan if I were you.

    yes was working fine yesterday, no power downs or anything, just a little load first thing in the morning for about 10 - 15 mins.

    What I cant work out is that it starts up perfectly if i hold the CPU fan in my fingers not attached to the Heatsink, as soon as I seat the fan and screw it down it plays silly buggars

    Is a strange one. You have to ensure that the fan is tightly secured down on the heatsink - does it clip in tightly ?

    It could be a bearing going bad, if the fan sped drops below a certain threshold, most mobos will declare the fan faulty. Try watching the fan in the bios and checking what it's speed is when it sounds an alarm vs. when there is no alarm.

    Well thanks to both you guys aitken and sam. I decided to go and buy a new fan (baah humbug!) and everything is working just fiine. A lot quieter and cpu temp when using autocad and excel together along with WWW is only rising to a max of 63 c.

    Many thanks
