your CPU at stock runs at 3.4ghz and will turbo boost up to 3.8ghz by default. what he meant was that he believes the CPU down-clocks at 80 degrees...that's completely false. it downclocks to 1.6ghz when idle as a power saving feature by default. but nevermind that.
but either way 80C for stock. there got to be something wrong there. unless he lives somewhere very hot.
and since they have the thermal system on the new boards i asumed they dropped of turbo when temps or power went out of spec.
