I don't think it is possible to get <80 C on air cooling at that voltage and clockspeed. Even the Noctua D14 cannot cool that much at 4.4 GHz with 14C ambient temps.

Well, I got pretty close with semi-lapped cooler and lapped cpu. Will have to work on more later.

It is a higher clock speed... frequency adds some heat as well.. my PWM fan is not running as hard either...

It did not make as much of a difference as I thought it would... even though I have not got the cooler base perfectly flat yet and the cpu might need some 2000 grit to put a better polish on it. I guess it has helped my idle temps so far. Will probably work on the cooler a bit more tonight and take a few pics of progress. Has anybody sucessfully lapped an Armageddon or equivalent cooler perfectly flat...??

I wrote down the batch # before lapping the cpu, in case I decide to sell it in the future. The cooler is not the only factor allowing me to these high clocks in 20-25c ambient room temps.
