Pros: My old fan were running loud and slowly wearing out one by one so I figured I would just replace all 5. I also bought a VANTEC NXP-205-SL Silver Fan Controller Panel so that I could controll the fan noise when I wasnt working on the computer. Well let me tell you, I wasted 16 bucks on the fan controller becuase I cant hear these fans on high speed let alone low. These fans are great. My onboard temp monitor is actually lower then what I normally run too so they cool very well also. Two birds with one stone.

Cons: NO Cons. These fans come with screws and 4 pin to 3 pin connectors. They are ultra quite and very inexpensive. What more could you ask for in a fan.

Overall Review: Heat is the biggest killer to computer hardware so buying a few fans is cheap perventive maintenance in my opinion. These are awesome and I would recommend them to anyone.

Pros: I havent owned it long but so far it works great. Plus the lights are a very nice touch. I bought 5 VANTEC SF8025L 80mm 2 Ball Case Cooling Fan to hook up to it and unfortunitally they are very quite so it kind of defeats the purpose of the controller but oh well.

Cons: It could used a light switch. The model up from it has one so I guess its my own fault for being cheap.

Overall Review: All in all it worth the money and a must have if you have noisy fans that dont need to run all the time.
