Ive had my computer for around 2 years now and the cpu fan has started to sound really loud! Does this mean my fan needs changing or does it need cleaning because i havent ever cleaned it (or really got into the computer) since i bought it.

BINGO! :D

On mine, have to clean it every couple of months thanks to a dusty house & crap case (no filters). 2-years I can imagine its picked up quite a few 'landfills' & dust is know to be a fire hazard inside computers, but don't quote me on that :)

Can of compressed air while hold the fan blades to stop them spinning or take it out and blow on it.

I heard from somewhere that using clean compressed air wasn't safe as some liquid came out with the air. Is that true? because I would really like to clean out my case.

I was told instead to just hold the nozzle of the vacuum cleaner over the heatsink but in the end I just used a soft paintbrush.

Well most people would advise you not to open the PSU, even when its off, the capacitors can still give off a dangerous charge. I opened up 2 PSU's and didnt even know what i was doing :p But yeh, if i were you, i would be careful if you do open it. But if you do, just unscrew the fans, and dust them off. Get a hoover and put a paper cone over the end, and just clean it up inside

If you're gonna clean your case with any form of air, either unplug fans or preferably stop them. If the fan spins too quickly and it's still connected it can blow the mobo.

And please be careful if you decide to open up PSUs. They can easily hospitalise you even when unplugged. Use a bulb or something across each connector to discharge the capacitors before you open it... and don't touch anything that looks unsafe.

Fantastic way of further quitening your fans after cleaning is to get a can of 3-in-1 oil and put one or two drops on the fan spindle, works especially well on older fans ;)
