Zalman CNPS9500 LED Ultra-Quiet CPU Cooler with Blue LED (Socket 478, 775, 754, 939, 940)

Average customer rating: 5.0

Good performer at price
Love it.... bought 4 of them
So quiet you can hardly hear it. Cools very effectively and on some systems pushes hot air out of the back of the case.
Great for overclocking
Cooling down the fire of Pentium D.

Performs well for me. Never allows CPU to go above 47C on load. Like the switch to control fan speed. Can't hear fan but then I have a pretty good case.

I really like the CPU cooler. I've purchased four of them for my various computers. It is super-quiet and works well. Installation isn't super easy but it isn't difficult either. Just be careful not to slice yourself on the very thin copper fins. Also, make sure to install the fan so it blows in the correct direction (see the documentation as it may not blow in the direction you think it does--the fan blows into the fins).

Typically the loudest thing in your PC is the CPU fan. When I set about to make my PC quiet for the living room the CPU fan had to go. Enter the CNPS9500, a truly outstanding product from Zalman.

I attached this fan to an external power supply for testing and was amazed at the mass of air being pushed through the heatsink blades while there was nearly no noise at all. Comparatively my Intel heatsink fan that came with my P4 HT screams like a jet engine. More realistically it sounds rather like a dust buster set on low. Regardless that amount of constant noise can become grating.

The installation was very simple on my ASUS P4P800 Motherboard. The heatsink is a bit heavy so I was prepared for the worst. Apparently on some AMD boards you must install a support plate on the opposite side of the motherboard which almost certainly means removing the board from the PC case. Fortunately for me th CNPS9500 attaches to the standard heatsink brace found on motherboards for socket 478.

Cooling appears to work well. My CPU does operate at roughly the same temperature as before. Perhaps on a few occasions the temperature is down by a few degrees. I would imagine that the sheer size of this cooler would appeal to overclockers because the heat dissipation probably has enormous potential.

A not-so-obvious benefit of the CNPS950 in most PC cases is that the fan is oriented perpindicular to the motherboard so it will help blow air toward the rear exhaust fan or out through vents.

I purchased a Zalman VF700 for my video card at the same time as the CNPS9500. The two Zalman heatsinks are finely crafted and look like they meet some exacting tolerances. Both of them are very quiet and made me realize how loud the fan on my power supply is now that it's not being drowned out by my old CPU fan.

Some of the edges are a little sharp. I think it isn't from poor manufacturing but rather because the blades are fairly thin and there are many of them, smoothing them individually would be an expensive process I'm sure.

Nearly a perfect product. Before purchase check the dimensions and verify that you have enough room in your PC for the CNPS9500. Also consider that some motherboards will require you to access the area of the board behind the CPU making it likely you will need to remove the board from your PC to install this heatsink.
It may also be heavy enough to wreck a poorly constructed motherboard.

This fan is great as the CPU temperature is always low even with the overclocking.

try it as its worth the money no need to buy liquid cooling unless you are going to extrem overclocking.

Cooling down the fire of Pentium D........2007-04-25

Purchased it in Aug 2006, to cool Pentium D 840. I bought the CPU knowing that it had heating issues, but I wasn't prepared to see it going over 70 C! My PC halted twice in its first day, once during a heavy install and the second during partitioning of and old hard drive that I attached, both due to overheating. I had initially both Mascool cooler and I called the manufacturer, they told me to return it right away.
So there I was, with a newly built PC full of bang and no cooler. Sad picture. I did a heavy search of both user reviews and benchmarks of over clockers.
I ended up baying the Zalman 9500 without even realizing it had the LED :) since I was so caught up in the temp charts. Used Arctic Silver and not the included paste.
Installation: Can be tricky.. be sure to read the quick install guide. Also the design of the bracket and the unit itself does not prevent it from rotating, so be sure to tighten up good. Make sure it blows the air out of your case and not on the chip set or memory.
Result: Down to ~48 C, and doesn't let it over ~55 C. No noise, no system halts :).
Heavy coper design, only thing better would be liquid cooling.
