    K8N NEO4 fan making noise... what does that chip do?

    I got the K8N NEO4 motherboard like you see here:

    The fan on the little chip is starting to go bad. But I'm curious what that chip is for. Is it the onboard graphics card or what?

    Nah, this thing's got no onboard graphics, according to spec. It looks like a southbridge strategically positioned to provide additional cooling to the video card. It's unusual for a southbridge to require cooling, though.
    All the buzzt!

    It's a combined South and part-northbridge (since the other part of the northbridge is in the CPU), and I don't think it's unexpected that a dual-PCIe bridge would require a bit of cooling.

    If your box is running hot (that is, the ambient temperature in the box is above, say, 30'C, then you probably need a fan there). If the box isn't fully loaded and running cool, you can probably just have the heatsink [although I do not take any responsibility for that].

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.
