Hi all,
I've just swapped the wasted fan of my Radeon 9800 for the fanless Zalman zm80d-hp. Though it's quite a hassle to install, it seems quite efficient. However, as the thing gets hot when operating. Not much than with a fan, but I'd like to treat this card well

Under Windows I use Radlinker to downlock it to 250/250, and I'd like to know if there were the same kind of program under linux, or if I could modify something so that it would boot at slower frequencies. All the OpenGL I need under Linux is tuxracer, so I don't think I need all the horsepower
Thanks for your help !
