I have the Freezer7, which looks like the exact same unit for socket LGA775.
I've never seen my P4 3.4GHz temperature go over 50C. I used Arctic Silver thermal compound instead of the stuff that came with the fan. It's very quiet too.
One thing to be careful about is the motherboard fan speed monitor. My ASUS P5GDC Deluxe powered down 10 seconds after turning it on when I installed the fan. I didn't know what was going on until I read that this can happen when the motherboard determines that the CPU fan RPM is too low and shuts down to protect the CPU from overheating. The Freezer7 fan is designed to run at a lower RPM than the stock fan, but the mobo didn't know this. The solution was to hook up the stock fan long enough to boot into the setup menu and turn off CPU fan monitoring, and then install the Freezer7. It was a pain, but after that everything was fine. Never boot it up without a heatsink/fan installed though, even for a few seconds. Those Prescotts heat up *fast*.
Overall I'm really happy with mine. Got it from Directron.com for $23.
