CPU fan is running at full speed all the time HELP !!

the musicman · 08-15-2006, 11:44 AM

my CPU fan is running at unsually high speeds for simple tasks.when my fan is working at 100% all the time it causes my P.C to run alot slower and creating alot of noise. i measured the temperature of my CPU and it was around 70 degrees celcius, sometimes it becomes hotter but sometimes its slightly cooler.
heres the spec of my P.C -

Advent T9402
Windows XP home edition
Intel pentium 4 HT processor 570 3.8GHz
500GB hardrive (2x 250GB)
just over a GB of ram
ATI 256mb graphics card

does anyone have any ideas about what might be causing this ?

Ditto...take the fan off the heat sink of your cpu and blow it out as well!

Indeed. There was a similar problem like this on a friends graphics card, all the fix was is to blow out all of the crap that was clogging the heatsync on it. Although if it continues then I'd be a little worried because thats quite a high temp to be running at for that model processor.

What heatsync are you using? How old is it?

that is meltdown territory, is the system stock cooling. May need to consider and upgrade... quick

Yeah that's exactly what I thought. Might be time to purchase a better heatsync and thermal paste. Is that the temp when under heavy stress or when idle? Whats the room temp like?

the musicman · 08-15-2006, 05:29 PM

the room temp is only about 20-25 celcius at the most.

when idle the temp is about 60 celcius
when i'm actually using it runs anywhere between 70-75 celcius

so just blowing out the dust on the fan and giving it a clean just fix it ?

thanks for your help so far

I take it that it was the dust and other crap gathered up within your heatsync that was causing the problem then? If you would have ran it at that temp for any longer without having cleaned it (which would most likely make the temp go higher), you would have seen a square shaped hole in your motherboard where your processor once sat.

yes it was, as soon as i cleaned it all out the CPU temp dropped by about 25 degrees celcius.
