    My 7800 is hitting some silly temperatures. It is probably a case of poor airflow, but when I migrate my system into a better cooled case that should be fixed.

    In the meantime... do you guys think this looks feasible?

    Here's where I found it.

    It's just the fan taken from the stock cooler that comes with A64 chips. Do any of you guys think there could be any problems with this? Because it looks and sounds like a good idea.

    Feedback would be appreciated.

    Yeah I've done that, and got an Arctic Cooler on the bottom one too.

    Strings, I don't see why that wouldn't work as a temporary measure

    Nice lads, keep the temp results coming.

    I know water cooling is a little more forward but it cant be beaten on the GPU,
    my 7800GT hits 35oC max and 30oC idle with a DD Maize 4 block. Thats with the clock speeds at 560/1300.

    Artic Silencer are awsome as im sure u all know.

    Done that mod with the fan that came with my stock H/S, 37C idle and never went above 50C during 3DMark05 and is very quiet. Thats with fan at a permanent 100%.

    I tried water on 2x7800gtx with a PD 3ghz & my resinator croaked with steam venting out the top, not tried with AMD but reckon would need put fans around the resinator, lol.

    Thats the best thing about this mod, the fans we have used are very thin thus dont interfere with any other slots.

    Well the update is, I couldnt get a fan to screw on top of the GTXs heatsink.

    SO!

    I just got a couple of your average elasticated bands, and just bound the fan to it.

    Temps are now 45 load, instead of 70-80 load.

    That is a ridiculous improvement, and this is still with the stock fan causing a little bit of turbulence.

    So aye, if your looking for a curious way to try and lower temps, give this a go. It really is quite spectacular :)

    A friend did a similar thing with an artic cooler, he removed the plastic bit and just put an 80mm fan on top of the heatsink, lowered the temps by about 20c i think.

    All too much effort for me. The hardest part about my little trick was removing the stupid plastic cover that cases the 7800s heatsink. Due to the fact I couldnt find a small enough screwdriver.

    Oh aye, and it's also quite quiet... I dont seem to be able hear the noise my 7800 used to make. Tis all good when you use your imagination a bit :)

    Why even by a Zalman when you can remove the plastic cover from the stock case, unplug the stock fan and screw on a thin 80mm fan (the one that comes with the stock A64 HSF is ideal).
    im running 516/1.37 rock solid.
