The page has a couple shots of the heatsink used on Penryn at IDF. Notice those black plastic locking tabs commonly found on Intel's current HSF that everyone seems to hate. If this is truely a new oem heatsink design, It looks like a pretty nice unit.
Great find. I thought it looked familiar, but I didn't have time to go through all the HSFs at newegg to see if it was indeed an aftermarket unit. Yep, I would agree that it's the Coolermaster. I guess Intel doesn't have an updated HSF after all.
The AMD heatsinks were really good at what they did. Especially the higher end AM2 and FX cpu's that included heatsinks.
Intel pretty much packages a standard heatsink that does what its supposed to, keep the cpu from frying.
I second that. AMD's K8 heatsinks do work pretty well, even the old-school aluminum-brick one like on my socket 939 X2 4200+. It's pretty quiet and my chip never got above 45 C running at full load. I've not had as good of luck with stock Intel heatsinks. The heatsink on my parent's P4 1.8 Willy doesn't work very well and the chip is usually in the 50s. A dual Irwindale Xeon unit with the 1150 g copper heatsinks works pretty well as the chips stay under 50 but those suckers are L-O-U-D. Intel would not do badly to go with the Cooler Master heatsink in the future.
the dissipation area matters as well + noise. ive found with one build the stock coolers fan doesnnt even need to run at full speed when you start up+ its quite quiet. i do hope intel does go with everyone else in this heat piping matter. love to see new ones for the higher end procs as well as different ones for lower end because right now, all they doing is shipping built up inventory from the pentium ds.
