Quiet and cool
Although large and heavy, it runs several degrees C cooler than the heatsink/fan delivered with the Intel Quad Core CPU. Running Core Temp, all 4 cores run under 40 C where as the Intel factory provided system was running 44 and higher at idle temps and 65 C + under load, which is what prompted me to purchase a larger heatsink.I rarely hear the fan spin up faster and never see temps over 45 C even while running gaming applications.CON: It is large and may require a little caution when installing depending on how your power wiring in your PC is setup. I had to tie one power wire to the case to keep it from touching the heatsink. Also it's own power wire for the fan needs a little care when installing. It can be pulled to tight and interfere with the fan.Install was simple but does require you remove the motherboard as there is a back plate you must install to support the weight. It does not use the horrible push pin locking system that the factory...

Excellent Cooler. Works flawlessly on LGA1155.
I was a bit confused because of the mixed reviews and the conflicting information in Amazon.com's product description. Contrary to what Amazon.com states above, they are actually shipping the *current* model of this cooler, which is the Zalman CNPS9900A LED. This latest model of the cooler comes with a mounting bracket for socket LGA155/1156. One of the reviews is from 2009, well and perhaps that is why the information is inaccurate. This is the *latest* version of the cooler, and it is *beautiful* and *effective!*However, assembling the cooler is a bit trickier than the instructions report. The instructions correctly state that one has to remove the protective shroud before using the cooler. What the instructions do *not* say is that the protective shroud must be removed *before* one can install the base bracket on the cooler to mount it in the case. I wasted quite a bit of time trying to install base bracket on the fan before I realized that simply cutting off the...
