Summary: i got it for 6$ when it was on sale, it does the job to keep the cpu cool like a stock cooler. i had an old 775 cpu that i didn't want to throw in the garbage so i decided to make a cheap computer that i would use as a file sharing server.
Pros: cheap, does the job if you have an old 775 cpu that you don't have a cpu cooler for.
Summary: The fan, is quiet and pushes a fair amount of air. My only problem was due to my motherboard being mounted on a plate, I had to remove the push pins and use threaded screws to secure it to the board. I have since replaced that tower re-installed the push pins and it still performs great. As my nick imply s I'm 68 yrs old and still love building computers.
Summary: Ignore the first reviewer named 'patch', this heatsink-fan device works perfectly on a 775 socket, and all 775 sockets follow a standard, they ar all the same size. When one has no idea of what one is talking about, one should abstain from writing a review.
