I recently upgraded to a Noctua NH-D15 for my stock i7-4790K 4.0GHz CPU.
After applying MX4 thermal paste, the size of an uncooked grain of rice, I was receiving excellent temps. In Prime95 v26.6 on SmallFFT I was receiving 64c after 15mins. As you can imagine I was very happy with this.
A couple hours later I decided to give it another shot for some reason and now I was receiving much worse temps in SmallFFT at 73c. My ambient room temperature barely changed being in the mid-to-high 20c.
Anyone know what just happened or why this happened? Surely the thermal paste should still be working optimally like it was. Is it possible that the huge heat sink some how loosened after standing on it's side for a while and if so is this not a problem? Or is my CPU busted or something, is this an RMA concern I should be looking into?
