Fire up your predator and go to modify parameters (in which ever tune you used). Scroll to the cooling fan section (You will have 2 locations AC Off and AC On). In the OFF section you will have 6 locations to change the fan temps, toggle to each one and change as you feel fit.
For myself
at the Hi Speed locations I picked 191 Deg.
at Med Speed I picked 185 Deg
at low speed I picked 181 Deg.

In the AC On section you'll have 3 locations to change the fan temps....I worked it the same way. After all your adjustements are made...you'll have to load again!
Good Luck
