Wth, when you're not at load the Fzr7pro is almost silent, you can even tune the fan speed in BIOS to change with the temps.
I think you must have installed that wrong in the first place, the fact you think that this new one is bending your mobo isn't exactly much reassurance either.
edit: just noticed i already posted same thing lol.... a while back. funny how my opinion hasn't changed since then
my frz7pro is in my brothers computer silent, my Ultima-90 is in my computer being bloody noisy. The fan on it is sooooooooo getting replaced lol. Want my computer to do under 20DBA
