    My motherboard (EP-8K7A+) has a small fan on it about 4cmx 4cm (picture here: http://www.pchardware.ro/Reviews/review.php?id=114)

    It sounds like it's on its last legs as it's making strange whining noises.

    I've had a quick search but can't seem to find anywhere that stocks them.
    Anyone know where I can get one from?
    Alternatively, is it possible to replace this with a heatsink?

    BTW, what is this fan cooling? Obviously not the CPU but I guess some kind of additional processor?

    Its cooling the Northbridge chip, you should be able to replace the fan with a heatsink. Have a look on www.quietpc.com\uk at the zalman northbridge cooling heatsink £15 (you'll probably get it cheaper elsewhere)

    It's your northbridge chipset fan. I went through 2 of the lousy things on my old PC. I actually got a replacement firstly from the mobo manufacturer, but that failed too! (they really are cheap and nasty), so I ended up sourcing a better generic one.

    I think this is the one you want, but I'd phone them up to check (Chillblast are very helpful)

    Thanks guys.
    Before I order a replacement, which is the better option - fan or heatsink?
    I guess the fan will give better cooling but the heatsink will be quieter?
    If I'm not playing games, etc. will this chip get really hot under 'nromal' use?

    Under normal use the northbridge doesn't get that hot, and many mobos just have a large heatsink. Given a choice on a new board, I always go with the passive cooling to keep the noise down.

    If you don't mind the hassle of attaching the new heatsink (never changed one on a northbridge, so I can't help you there), then go with the passive option. If you want the easiest route, put on the 40mm Papst fan. They're nearly silent anyway, and just attach by screwing down onto the heatsink fins. Check that the power connector is the right flavour though. I've just looked at my old Northbridge fan and it's 2 pin, compared to 3 pin on the Papst ones, and it looks like yours is too from your piccy. If so, you'll need a 4 pin to 3 pin molex adapter (see below) and just run it straight from your power supply.

    Thanks Yandros.
    I think I'll go for the heatsink option then as it's less noise and also one less thing to break in the future.

    Just need to work out which one I need.
    Guess I'll have to remove the old fan and see if it's glued or pushpin?
    Looks like pushpin to me but I'd better check.

    Thanks Steve - already ordered one after checking the links Yandros provided earlier :smashin:

    I just unplugged the fan to get an idea of what it will sound like when I get the heatsink and I swear I heard a pin drop...;)
