yeah... either point the Evo toward the back of the case and the exhaust fan or the top of the case (if you have a mesh top or exhaust fan up there)
don't blow the hot air back down on your gpu.
with 45% load on gpu its goin 50c
ya i have top mesh n top fan also . now to replace the fan to topwards i need to remove everything from or just remove the fan n replace it ??
