Summary: Used this on an AMD 6000+ Dual Core. It installed nicely. I usually have trouble locking these fans down the first time but this one was easy despite my initial perception. It has a speed controller which I set at high and don't touch. For some folks noise is a problem but for me I want a cool chip. All in all this is a decent product though I think fans in general are overpriced.
Summary: This thing is BIG and heavy. When I first took it out of the package, I wasn't sure it was going to fit on the MSI K9N board with the RAM installed but this just cleared the RAM and bridge cooling fins on the board. Fan is silent even at full speed and also moves enough air to help cool the RAM and surrounding chipset fins and heatpipes. Temps on my AMD Phenom x4 stay around 27C at idle and around 40C at load. (not OC'd). Highly recommended.
Summary: all in all this fan was an ok fan. comes with a little tube of thermal grease which is just enough to get on ur CPU. I am 14 and I got this fan for my new and first build. works like a charm. Comes with a speed adjuster. a little loud but keeps my computer runnin cool. I am 14 and like I said this was my first build with my first fan so I have nothing to compare it to. The fan is pretty big btw just a heads up looks way smaller in the picture :x. I'd recommend though.
Summary: You can't go wrong with this fan. Used it with Athlon II X4, and CPU temp's below 32 dec C. Power Up Black Mid T ATX case had cooling duct that aligned perfectly over the fan to pull cool air in from outside the case.
Summary: It's impossible for me to rate the performance of this cooler. From all accounts, it does what it is designed to do, IF you can get it mounted. I don't think I would have any complaints, if I was able to use it but the tie down clip interfered with a capacitor on my board and prevented me from installing it appropriately. I'm looking for another solution.
Summary: It fit and installed easily. Performs well and is fairly quiet in operation. I especially like the feature that allows the adjustment of fan speed. I would buy this one again although the price seems a little high.
