under clocking will lower temps, but as far as how low u can go, im not sure... i may be wrong but i would think u would underclock in the same fashion u do to overclock... go a little at a time

and please fill in your system specs under user cp, it helps us better help you, thanks

ok, so i would try underclocking it in the same fashion as overclocking it, do you know how to do this? do u have atitool or a similar program, and also a temp. fix could be run a tube from one of your intake fans directly over the gpu hsf,but leave just a few inches of space over it, it will help with cooling

ok so underclock your gpu using atitool, take it only about 5-8 mhz at a time, testing each incrament to see if its stable...and your temps should drop a bit...

ps: my room used to get hot as hell too, it sucked. but a hot room will also raise your temps... so a cool room would be best

yea well as i cant change my room ill haveto make do with lowering the temps produced

do u have any idea if underclocking has the same risks of damage to your card as overclocking?

ok so start by underclocking, and be warned u will loose performance...
if you havent overclocked read through this real quick, except do the opposite, turn them down not up, and maybe not go to your max, just go untill u see the temps drop some...u be the judge on how far to underclock
