Pros: Wow, I honestly couldn't even tell these fans were turned on when I powered them up. I bought 4 Scythe F and 3 Scythe E because I thought the F's would be too loud for not being on a fan controller.....wow was I suprised. I actually called Newegg that day and returned the 3 lower speed fans because THESE 1600rpm fans were dead silent. I couldn't even tell they were turned on until the Air started to hit my arm. They are fairly powerful and I am in love with fluid bearings now!

Cons: The 3-pin wire isn't as long as I would like, but to understand my circumstance I had to buy additional 24" 3-pin extenders.

Overall Review: If you need to plug them into a 3-pin fan controller you will def need extensions...but most fans do. Don't worry about the price, this fan will last you several computers. By the end of August I will have 1 on my processor heatsink and 7 as case fans.
