Since i put my Zalman heatstink on my Vid Card it hassn't gone above 55C but i think anything 65-70 should be looked at as a concern. Even 55 is kinda hot but i have no problems.
ok well im gonna stick with thinkign its the psu thats messed up then bine hasnt passed 45c and it is the drivers so i guess ill i have to inverst in a new psu....
