I purchased this fan to go with my Pentium D 830 on Intel's D955XBK motherboard. I used as many "silent" components as possible, including the Antec Phantom 500 and Lian Li's PC6070 Plus silent case. All great if you aren't on a budget.
In any case the Zalman cooler may be the best purchase of all. It was easy to install, though it is very large and may not fit on all motherboards/cases. It came with some decent thermal grease too, rather than one of those cheap little squares that even good fans sometimes come with.
When I first installed it I also connected the little speed controller, but the fan was so silent that I realized that I would never manually take it off of the highest speed and ended up disconnecting it. The motherboard has its own automatic controller anyway, but even if it didn't I would just let the fan run on high all of the time.
Shortly after installing I noticed that when the CPU ran at full load the system overheated. Once I was satisfied that the case and PSU fans were functioning fine and weren't the culprit I removed the Zalman and replaced it with the Intel fan that came with the chip. Not only did it sound like a 747 but it actually did a poorer job of cooling the system than the Zalman, with temperatures averaging 4 or 5 degrees higher under full load.
So in short the Zalman does a better job of cooling than the stock Intel fan and at a much lower volume. I've come to realize that short of water cooling there really isn't a whole lot you can do with a Pentium D, they just run so hot. I'm considering using Zalman's silent water cooling in the near future, but for those people who don't want to go that route or for people with single core processors I highly recommend the Zalman CNPS770-Cu.

108 degrees F with a P4 3.0ghz cpu
BIG COOLER, BIG FAN, BIG TEMP DROP. On a P4 cpu this cooler clips right on mobo plastic bracket.It's no harder to install than the factory cooler. My factory cooler with a P4 2.4ghz cpu steaming video ran at 122 degrees..A used P4 3.0ghz with this Zalman 7700 runs at 108 degress F steaming video and 85/90% cpu usage. Easy install..Lots of brackets for other processors..You can order a spare fan and bracket from zalmanusainc. for 7 bucks delivered to your door. But you'll never get it. I know I paid twice, once wrong fan and once nothing.
