Recently my GPU has given up the ghost so ive installed my old GPU, but this cards fan is slightly audible even when not gaming, so i downloaded speedfan as i know you can adjust fan speeds on it, but my question is HOW do i do this? theres loads of options on speedfan, and % boxes which ive moved up and down trying to guess which one it is but nothing happened so i guess ive not found it?
The card in question is a XFX 7600GT
speedfan question 
Linear Mode
