Well not literally. Assembled everything today. Powered on and no bad POST beeps. Entered BIOS. Went to the hardware monitor and the CPU temp was at 85 deg cel/ 185 deg feh!!! The motherboard temps were fine. I immediately shut it down. I opened it up and placed my hand around the CPU are and CPU Fan area, no hot temps at all.

I'm pretty sure the BIOS was right and I probably didn't feel any heat because it wasn't on for too long.

Obviously, its probably a problem with installing the heatsink correctly. I have the ZEROtherm ZEN FZ120 and used MX-2 Artic Cooling thermal paste. The only thing I can think of is that the heatsink isn't close enough to the CPU. Isn't the copper suppose to touch the CPU?

This is my first build, so I am still a novice. I knew if I was going to have any problems it would come from the CPU heat sink...

Let me know what you guys think it is, and how I can fix it. Thanks!

Did you try re-seating the heatsink? Yes, the copper on the bottom of the heatsink should be touching the cpu (w/ the MX-2 in between obviously). Make sure you have the heatsink properly installed.
