I never turn down the fans to decrease the noise. I'd rather have a noisy computer than a fried one.
All fans are spinning fine, that was the first thing I checked.
Case is a Antec Nine Hundred Gaming case and everytime I check it and the fans, it always feels cold with good circulation.
I quite literally put the board together a couple of weeks ago, I still haven't put the sound card in yet. I had some problems with connecting the hard drives (I had followed the advice of a friend and RAIDed them, they didn't take to the new hardware very well).
After the drives were fixed I connected all the cables in the box and switched it on. Problems with the computer switching off were almost instant.
I've used the case before, but I cleaned the dust out of the case before putting in the new hardware.
I'll clean the CPU and fan block when I get home from work and apply some thermal paste, ensuring it's the size of an an uncooked grain of rice.
White rice or Brown? Are we talking long grain or basmati rice? Risotto rice is also kind of fat.
I'll let you know how it goes. Fingers crossed.
Thanks to everyone!
