Noctua NF-A20 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (200x30mm, Black)

Set and forget at 700 rpm, at that speed these fans are dead silent, if you go higher they become a little loud.

This was easy to install and very quite to operate

This product comes with less than 12 of wiring to extend to and hook it up to your motherboard. In my case that was not near enough to reach the plugin port. It sits in my PC unused and worthless.

Ordered this fan to replace the 200mm front panel fans on my lian li 215 case. They would fit if they came with 35mm screws, however Noctua felt that was not necessary. All standard long fan screws are 30mm, this fan is 30mm thick. Its really cheap to not include 20 cents worth of screws with a $36 fan, very disappointed with Noctua right now. Best I can tell a M3x35mm screw is what you need, guess I am going to home depot to find screws now.

Exactly what I needed for my audio video receiver.
