Summary: This little 80MM fan is moves much more air than most of my other case fans. It is not loud at all either. The fan comes with a 3-pin and a 4-pin connector that are both sleeved with grey fabric, which is a very nice touch. Overall, a very solid product from MassCool
Summary: This fan includes connectors for the motherboard or the 4 pin power supply connector. A must for system builders or overclockers. Works great and noise is minimal. I recommend using sound dampners for better noise reduction.
Summary: Good fan, provides connectors for motherboard and 4 pin PSU connector. Good noise control in the mid 20's. For the money, you can't go wrong. Better fans available, but for about 2 bucks, if your happy, you can look elsewhere.
Summary: This case fan isn't that bad. I prefer the silent fans. This one verges on noisy. ST makes a good product and provides a good option fan with power connectors for both 3 pin and 4 pin connections. Decent option if you have no others.
