With the P18x case that should be fine. You have a 10deg drop in temps which
is pretty admirable. The only way you might improve that is to reverse the
top/rear fan to blow in and face it that direction for some direct airflow.
My P182 is modded by Swiftech with a watercooling system and I have the top
fan reversed to bring a bit more air to the radiator (which is where the
normal top/rear fan is) and the chipsets. As far as the HS moving a few
degrees, I wouldn't worry much. My waterblock moves a tiny bit the same way
and it works great and I tightened it as much as I could. Just as long as it
is making even contact across the CPU it is fine.
