How hot is too hoy for a PWM. I just added a custom liquid cooling radiator to my system running 3 fans on top of the 7 that I have cooling HDD's RAM ETC plus 2 Vid Cards. I dropped my CPU temps under full OC by another 11 to just above room temps but my PWM went CRAZY hot while running orthos I hit 70 (AND CLIMBING?). I know vid cards get hot but what is the tolorance of the PWM? I have found no info on this after 2 hours of searching for hours on the web.
