Summary: I have been through 2 of these and they just get louder the more they are used. They didn't stop working, I just pulled them because of the noise that it makes. Thermaltake should take there name of of this re-branded fan. There are plenty of liquid cooled fans on this site and I would recommend them to the people that want a silent cooling fan!
Summary: A word of caution tho' since no instructions were given I had to do some fansy thinking to figure out how this heatsink with Fan was mounted. Probably a UTube place explains it all, but didn't have access to net when I was installing.
Summary: Received an Intel fan and heatsink with the CPU. This combo is 50% larger ! Quiet and came with heatsink compound on it. Don't know how long a life it will have but right now, would recommend this very highly.
