Summary: good replacement for stock intel cooler. it's very affordable and you don't need a backing plate to install it, which means you don't have to remove the motherboard from your case to install it. that saved me a lot of trouble.
Summary: Performs well, but does not fit a majority of aftermarket motherboards due to close proximity of capacitors to the 775 socked. This is true of both older and newer 775 mobos--I've only see a few that it does fit on. If you don't have a good half inch clearance around the socket, steer clear.
Summary: Bought this to replace the OEM Intel fan for my media system, because I could hear the "whining" sound when running my machine. Thought this would take care of the issue. It works fine and is quieter than before, but still some sound when movie scenes are silent.
Summary: Being retired I needed a low-cost solution to a custom media server that I built in that the original CPU fan was noisy. Previous reviewers stated this replacement fan to be silent and efficient... It is both.
