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

This was easy to install and very quite to operate

I really wanted to like these fans and in the hands, they appeared to be of excellent quality. The only problem is that they will not fit into the 200 mm fan slots in the Coolermaster H500m case. Their additional depth (or thickness) is the issue. Please fix this Noctua and give them more than 800 rpm, and Ill give them another try.

Very quiet, easy to install and just enough rpm’s to do a good job pulling the hot air out of my computer case with out sounding like it’s going to take off. Second Noctua fan I’ve purchased.

Great fans. One of the best or if not the best. Cooled my PC great and quietly.

As they state in the description.... Please Note: The NF-A20 has a 200mm diameter (7.8 inches), and a thickness of 30mm (1.18 inches). Please make sure you have sufficient space in your case.

good !!!

I got this last september to put in on my next complete clean. Well I lucked out on a 6900 XT for cheap. So cleaning. Put it in and hooked computer back up. All the fans came on but this one. It trys to start. On the third or forth time it spins up. Not sure what to make of this. Never had a fan do this and its my only noctua fan so I have no experience with them. I was going to swap all four but not sure now. Im using a thermaltake chaser mk I. Full tower....huge.

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.

Really quiet and just feels like a well built fan, also 30mm width fits in thermaltake core v21

Excellent 200mm fan using it on a thermaltake view 51 and at full speed its quiet.noctua fans are the best in the market..
