Pros: At the highest speed of 2,000 rpm, the fan is still fairly quiet. The build quality is solid. The fans are reliable and keep the system running cool.
Cons: The wires can be very confusing, and there is no manual that comes with the product. Fortunately, there is a manual online which is a little helpful, but pictures showing a diagram would be ideal.
Summary: I mainly chose this fan because I wasn't sure how much CFM I wanted or how loud a large CFM would be, and because my motherboard at the time didn't have the capability to control fan speed. The highest setting is pretty loud, as can be expected.
Pros: This fan can move a ton of air, and is about as quiet as a fan moving a ton of air can be.
Summary: Pros: Blue, Bright, Easy install, switchable speeds, quite Cons: None so far Other Thoughts: I do like that they come with both a 3 PIN PWM system board connector and the ability to attach to the Power supply using a standard peripheral connector.
Summary: The fan looks nice till you try to install it. The 4 screws that come with the fan are all rusty or were not threaded properly. had to to go out to buy the 4 fan screws a fresh. Once, I was able to add the fan in the desktop case - I realized it was too noisy and air that it was pulling out was too...
Summary: Love this fan! I use it as the 80mm exhaust fan on my micro atx gaming computer. Very bright, and might be a little too bright if used for a fan on the front of the case that was not covered. But for being on the back of the case it is perfect.
