I've spent two months, many hours and $ trying to optimize cooling of my new P4 3.6GHz system. After buying a 2nd case suggested by Intel, and trying two CPU coolers, the best temperature I've achieved is 57C at idle, on a cool day - wait until summer! If someone knows of a tried and tested solution for better cooling, please let me know. I'm driving an ASUS P5AD2 Premium, Corsair XMS2 (533) and a cheap graphics card while the PCIX market matures. I can tell you the Gigabyte CPU cooler (PCU21-VG) dropped the temp from 65C to 60, and the Thermalright XP-120 dropped it to 57C (all on cool days at idle according to BIOS).
FYI: The Thermalright XP-120 will work with the ASUS P5AD2 Premium MOBO with their 775 adapter and longer screws than what comes with the adapter.
