Humm. One thing I never understood about this "quiet" vrs. "performance" argument is that the higher the block performs the quieter you should be able to get the system. :shrug: If the block can remove MORE heat (higher performance) then you will need a smaller/slower/quieter fan on the rad.... This holds true if the high performance block works better at lower flow rates than a lesser block.
I don't know. Hell right now I got an XP1700+ running on a $5 HS with a 60mm to 80mm fan adapter with a 25CFM 80mm fan and it runs comfortly at 45-50C. That is also my gaming system. I can hear the hard drive over the HSF and I got a fairly quiet hard drive. Sure I probably couldn't do that with a faster processor but I don't need a faster processor. Plays all the games I play just fine UT2003/4 included.
I guess it is up to the user and their requirements.
