Pros: I have a Pentium D system (2.8 GHz). The stock intel fan was unbearably loud...you can hear clearly in the next room. According to the "sensors" utility (linux), the fan ran at 4,500 RPM, with the temp about 45 C. In January, 2012, I moved the computer into a cabinet which only served to make it louder. So I spent several hours shopping for a replacement heatsink. I chose this model because it seemed to be a newer design, and was well reviewed. My main criteria, noise, was completely resolved. The computer is now whisper quiet. My wife, daughter, and I all thought the computer was not running (when it was left powered on). The fan runs at 1900 RPM with a temp of 35 C. The cost of this heatsink was less than half the others I had considered. In addition, installation was easy. It was not necessary to remove the motherboard (my system is LGA 775).

Cons: None so far.

Overall Review: I guess my computer doesn't have to sound like a jet plane taking off after all.

Pros: I eventually got the product working, and working at "N" speeds, under linux (Ubuntu). The speed is 130 Mb/S.

Cons: Although the produce worked out of the box, it was not at the higher speed ("N" speed, I bought a matching "N" router to use with this adapter). It took several sessions over several days of browsing forums and re-compiling the proprietary driver with different fixes and hacks. Apparently, most users did get the driver to work, some quicker than others.
