Swiftech GPU block question

[darkzephyrin]

The background information: Swiftech has a fairly nice and relatively cheap waterblock for the GPU with an 80 watt pelt as an option. My watercooling loop can fairly easily manage the extra heat from the pelt so that is not an issue. Currently my GPU is aircooled and reaches temps upwards of 75C on hot days. This is unacceptable - i would like to bring it much closer to the 40C marker - and if possible - below that. I am fairly confident that I could do a good job insulating the video card .

My question is: Will I get any benefit from the choosing peltier option as opposed to the simple waterblock? Or rather yet - is it possible that the peltier will actually raise the gpu temps? The pelt is rated at 80Watts - The radeon 9800 XT (well - a flashed pro) gpu which this will be cooling puts out what? 80 watts of heat under full load? From what I know about peltiers - which is not much - they do not operate very efficiently under heavy load. Will a load like that defeat the pelt?

Thank you for your advice - it is appreciated!

not to say anything bad about this forum or it's folks (because they rock) but you're probably going to way to try a more extreme forum if you're looking for peltier+ options. You're sure about that the loop can handle the extar heat by the pelt? If you're CPU/NB is on the same, you'll see some unhappy decline in cooling on those. A lot of folks decide to do single wb loops when they decide to go pelt and above. I'd recommend the DD Maze4 w/o a pelt for that gpu. slap some ramsinks on it too and perhaps a cross-card fan to help cook them. If you mod the card for more voltage, you'll absolutely need extra cooling on it. If i'm not mistaken the bios mod that you've done has already increased the core voltage btw.

All that aside, if u just don't want to deal with it, slap some heatsinks on the ramsinks and then get a vga silencer. i know a lot of ppl who've had good luck with that. just measure correctly so your sinks will fit.
