Chalk up a 3.0 Ghz E2180 OC to the list. Board is an XBX2, cooler is a Tuniq with a low-speed fan 7 volt'ed (just a spare parts internet box for the gf).

A couple observations...

I can really see the difference in thermal transfer from the die to the IHS to the cooler with this series processer. Not like the higher-range cpu's wiith their soldered die/IHS interface at all. Very interesting how the temps ramp up under Orthos load with the paste style die/IHS interface on these things compared to my E6600. Almost seems a waste of time to lap the cpu and cooler & use Coolaboratory LM like I did, but I'm sure it helped some anyway.

The 2180 could probably do 3.1 Ghz but Orthos load temps were running in the ~70c range with the silent cooling solution I want to use, 3.2Ghz=unhappy machine, so I didnt really play with that speed too much.

All in all, not too shabby getting Core2 at 3.0Ghz for $90 delivered
