BIOS Not detecting Power Fan

Hi guys,

You can view my build here:
[SOLVED] $1300+ PC Finally here!

I got the PC working and everything seemed fine until today when I hopped on WoW for the first time, and after 2 minutes of game play it shut my computer down. I started it up and tried again but it shut it off again.

In my BIOS, it is not detecting my power fan speed. I opened the case, and my PSU fan is running but I don't know why it's not detecting it.

Also the CPU temperatures keep going up and up when I'm just sitting there looking at the BIOS. All 4 fans (stock) are running, but the CPU temperature gets in the 80's Celsius and keeps going up, but I turn my computer off.

I have no clue what to do, I don't want to damage anything and overheat.

Any idea on how to fix this?

Stock Intel fan? Check to make sure all 4 legs are fastened tight to the motherboard.
Is the CPU fan spinning? plugged into the CPU fan header and not a chassis or power fan header?

I added some Thermal Paste and everything seems to be fine now :)

That'll do it.
