First impressions:
WOW!
Specs:
Q6600 @3600 (9x400)
Asus P5K Premium(Black Pearl)
memory:2x1 gig Crucial Ballistix Tracers DDR2-8500
PSU:Corsair HX550
Cooling TRUE w/zalman 55CFM 120mm fan

Ambient temps are 68F
"Old" temps running WCG with all settings the same using AS5
49-49-48-47
New temps running WCG:
45-45-45-44
and this is not burned in..
3 mins after initial boot and right into WCG after checking system temps,etc.
TIM applied as I always do on the Quad: A medium "line horizontally and the same vertically and "seat" and move the HS 15 degrees side to side.
That's a average 3.5C decrease across the cores from what I thought was a very respectable temp.
I'm sold.

Forgot: idle temps at 3600mhz were in the high 20's.. Amazing!
