I have a 3 Year Old PC (Athlon XP 1800+, 1.2Ghz Appx) And recently the CPU fan has been making these strange 'buzzing' sounds, on startup, but gradually die down. On the temperature monitor, it first reads 40*C, but then increases to over 65*C in around 5-10 Minutes, even when I do non-processor intensive work (like web browsing). To avoid damage, I then shut it down. Should I buy a new CPU fan?

CPU fans are about the most common failures in a computer. Fortunately replacements are cheap. If you get a heatsink with the same size fan, you can even replace just the fan by unscrewing the old one and screwing the new one in its place. Have a look at what is available here click here

Check nothing is interfering with the fan i.e. a cable to a CD or HDD.

Case air vents are free, PC not sat on carpet.

A system fan may also help approx £4

I totally agree with Gongoozler, however, if you do replace just the fan, make sure there isn't a load of dust and fluff left between the fins of the heatsink.

A build up of dust and fluff will reduce the heatsink/fan's cooling capacity.

Be careful what way you remove any build up, static electricity must be avoided at all costs.

Thank you for all of your help. New PC fan is as quiet as a mouse. It doesn't have the problem anymore, and the temperature is on a safe 45*C.
