I've had good experiences with the thermalright heatsinks. I just recently upgraded from a xp-90 w/ 90mm quiet panaflo to a xp-120 w/ a 120mm panaflo and the xp-120 blows the xp-90 away. I can turn off the fan completely and have idle temps of 28-30c and with my panaflo fan on very low settings it would stay around 27c but if i put my panaflo fan at max settings it doesn't really make a difference. My room temperature is around 27c. My a64 3700+ SD is at 2.85ghz @1.4v
btw i have a lian li v1000b so that might play a big part in my temps as well.
