Cheers for the replies
Did you guys have the h80 set as a intake or exhaust
You'll see similar temperatures either way, because although the MX4 is slightly better, the pre-applied Corsair stuff is perfectly spread out, which counts for a lot.
Isn't this another one of those things were it doesn't make much difference either way?
Changing TIM and how it is applied can save, what, maybe 5C? Does it even save that?
MX4 is not actually better.
