Thread: sli 7900gt's need better air cooling...help me out plz

    As casecutter said, Swiftech is just about the only manufacturer of decent, all inclusive, kits.

    But for putting a watercooling system together, frozencpu.com has everything you'll need. You may be able to find some parts cheaper if you shop around...but the extra shipping charges may negate the lower costs.

    You'll want to go with 1/2" tubing, a dual 120mm radiator(minimum), and a pump that flows over 300GPH. I've got the Apogee CPU/GPU blocks, they are hard to beat for the price.

    Ati came out recently with a universal cooler that got a kick-ass award from maxpc, it is only 30$ too! I will notify you when the name comes to mind.(i forgot it.) You might not need the water cooler with them unless you want to spend more $.

    I have a slightly older Koolance Exos and I'm perfectly happy with it. Still I realize that the Exos II and Koolance newer products are pricy. Alternatively, I might suggest a Thermaltake Bigwater. The price isn't too bad.

    But First, I would just try to modify your case for better cooling. I use slot coolers to help keep my heat build up down. You might also think about mounting a Blower and directing it at your cards. Just make sure you have good air intake, or leave the side of the case off. (oh and clean that puppy out regularly as well )

    thansk guys

    55-58c is screaming hot...go water dude,my 7900gtx idles 39-load after 8 hours bf2 48 tops.7900gts been known to complety fail due to these temps.'

    "A few 7900GT users have reported that on back side of 7900GTs 2 components are getting boiling hot and they believe this is related to memory voltage regulators. They can reach boiling point like temps. Putting a heatsink on them helps alot apparently.

    But this could explain 7900GTs working on day 1 etc and later developing the problems with needing to lower memory clock speed, due to tearing/artifacting and freezes in apps. Maybe the voltage regular dies and doesn't give memory chips the voltage it needs to run at particular speeds ?"

    ........There have also been many issues with the 7900GT, paticularly EVGA 7900GTs. I had my 7900GT KO for 3 days before it started crapping out.....lock ups in games, really nasty artifacts, and flickering monitor then "no signal" message. I RMAd the card, and am waiting for a replacement.....but Ive read people going through several RMAs before getting a working card which really worries me <!-- --><!-- -->

    as far as the artic cooler...it wont fit the 7900gt.myabe the 7900gtx..my buddy gave me one to see if i can mod it to fit the 7900 but you have to cut the heat pipes and some fins to make it work and thats not worth it...but i also heard artic cooling is supposed to release one for the 7900gt..
