You gotta remember that the 920 pulls almost 200watts at load, stock speeds. The 965 (3.2GHz stock) pulls ~250w. Add another 800MHz and you guys may well be using around 270watts under load; that's a heck of a lot more than penryn/wolfdale.

As far as power consumption goes we're back in the Q6x00 days, in the 2xx watt region. It was common back then to see 50-60 degC under load.
