You mean there's 2180s which are NOT on the M0 stepping?
Nope, I'm just saying that the M0 stepping seems to reduce the temps somewhat.

I'd say M0 runs very cool compared to L2. Not sure how it compares with E6xxx range but unlikely to be much in it.
Here's my E2180 M0 with 1.4125v at 3.2GHz cooled by a Tuniq Tower and the system is running reasonably quiet:
It can do multi-core prime95 at 3.33GHz with 1.475v for over 6 hours but eventually fails and was running a little too hot.
