Don't forget mine is a shoebox size SFF HTPC which will run hotter than a large OC rig, and I'm also going on this guide:

If I've interpreted this correctly a CPU case temp of upto 50C is fine & cores at 65C. The temps I posted in previous post are at 3.6GHz OC. The auto speedfan control on my Shuttle defaults to keeping fan speed low until cores get to 75C I think and usually only running at 750-900RPM
