I just recieved my new Q9300 processor today and i was a little shocked when i first seen the new design of the heatsink. This thing looks like a U1 server HSF.
I thought it might be because the new 45nm proc's generate less heat but while talking with Lucas, his E8400 has the older (thicker) style HSF. If this HSF is enough to cool this processor, I imagine i'll be able to overclock this processor pretty high with my WC setup.
