Nevermind. The 38°C is according to the BIOS. Asrock's tuning utility shows 29°C - 30°C. Excellent. I'm gonna overclock this baby later on after the 200 hr break-in.

I have a Thermalright HR-02 Macho heatsink mounted on the 3770K cpu using AS5. My idle temp is around ~38C. Is this normal? I've seen others get it in the low 30s or upper 20s (air cooling). Bear in mind it's a new desktop. I heard AS5 needs to be broken in. Will it improve much?
