I've never understood why cooling fans on most PC kit pack up after a year. It's one of the most common failures, and yet no-one seems to realise that it appears to be the way the industry is geared - to make more money by forcing people to upgrade often!
I have a NVidia 7300 GT graphics card that is now about 14 months old. I have no complaints about it- but the fan died.
Anyway, quick call later I'd asked our resident techi at work to get me a replacement - which I picked up when I was in the office yesterday .. and fitted today.
Wow - I think he kind of went overboard :) At least there are no moving parts ;)
