GFX card heatsink problem?

    In theory it should only be ugly rather than dangerous. Helps if there's a fan in there blowing on the card's heatsink of course.

    I still don't get why passive cards are too flippin' wide for 99% of PC cases... that HD4670 looks like it'd have trouble fitting snugly in anything narrower than a HAF922! :eek:

    Thanks Solitaire, the case has 2 fans on the right side of the case, with the cpu between them and the gfx card.

    IIRC those are exhausts, at least on the early Fusions. They should pull down air from the top (kinda backwards) across the GPU and CPU and then out the side. You'd have more issues if they were the other way around as then the card would have to rely on the whole "hot air rises" bit for any air movement at all :o

    I got a passive card in my PC, it was a bit of a mistake as I had to point a fan at it in the end. They do need airflow around them or they'll just cook although your's is a smaller card, mine is a full sized HD4850 I really don't think they where meant to come with a passive heat sink, especially since mine is supposed to be a gaming PC. I've gotten around the problem with a small fan and a fan controller so it can speed up the fan when needed.

    If you can get a small little fan and point it at it. It doesn't need to shift much air just get some airflow over the heat sink. You should be able to get temperature readings from the cards software in windows that will tell you whether you need a fan or not.

    The temp seems fine. Its holding steady at 43-44 degrees, which is the same as the cpu. System temp from 34-37.
    I have not put it under heavy load yet.

    43 is fine, mine runs slightly hotter than that with a fan pointed at it, around 47 degrees. It can go all the way up to 100 and crash if there's no fan though.

    Yours does dissipate well over twice as much heat though :P

    Thanks guys, i will keep an eye on the temp monitor & hopefully i will not need another fan.
