the fact that the temps are higher than those with the stock cooler shows that something, somewhere has gone wrong.

like the suggestions above, you should remove the cooler and reapply a nice layer of AS5. make sure you clean both the NF4's core and the cooler's base properly, preferrably with isoprophyl alcohol.

what were your previous temps Fluxs?

i had no reduction in temps whatsoever. i think it must be the settings i use in the BIOS to lower the speed when the temp is less than X degrees...
