Installed a new MB (Sabretooth Z87), RAM (32G Corsair) and CPU (i7-4770K). With expectations of eventually overclocking it, I bought a Corsair H80i liquid cooler.
At max load (Prime95) it ran 100C. The pump didn't seem to be working on the H80i, so I exchanged it. Same deal.
Went back to the factory Intel fan included with the CPU. Same deal. About 50C idle and 100C under Prime95.
Is it possible for a CPU to be defective in such a way that it runs extremely hot even at stock voltages and clock speeds? Otherwise, I'm at a loss. My old 2600 ran at 4GHz colder than this thing does at its 3500K stock speed.
I have redone the thermal compound a couple of times. I've tried to dab in the center as well as the business-card skim coat of Artic Silver 5. Good contact, but it hasn't helped. I've verified the fan is mounted properly and the pegs come out the back side of the board, etc.
Thanks for any tips.
