Mine sits nicely at:

Idle:

CPU: 32 Degrees C
Mobo: 18 Degrees C

Load:

CPU: 38 Degrees C
Mobo: 22 Degrees C

Bit of a weird cooling method, at the moment, though, until I get the new case......case-side removed, 12" deskfan directed inside the case, and regular clean-outs with a "dust-buster" compressed-air canister!
