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

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.

It is a little expensive (as most Noctua fans are), but it is well worth it. I had a lot of trouble finding a similarly sized fan with PWM control, and I know this fan will outlive my computer so I can reuse it again for my next build. It moves a good amount of air and is completely silent, plus you can adjust the flow as needed with the PWM control. Very high quality, but then... would you expect anything else from Noctua?

Good job Noctua.

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.

I bought this fan to replace a failing Cooler Master A20030-10CB fan that was mounted to the top of my Cooler Master HAF 922 case. It turns out the presence of 170mm mounting points on this fan prevent it from fitting into this particular case, which uses 154mm hole spacing. I did not know this before I bought the fan. Nothing some marking and quick Dremeling couldnt solve, though! Now that the fan is in the case I love it. Almost silent and moves a lot of air. Huge improvement over the fan I removed, although that one was 8 years old. Well see how this one holds up.

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.

I bought a new Cougar case because it had a solid side panel with a perforated inlet for a 200mm fan. My system is air cooled. However, the size of the CPU cooler that was on my mobo, this would not fit inside, so I opted to mount outside as in the picture. I was worried about the noise at first. But top speed is 800rpm, and the fan is really quiet. Even while gaming it doesnt whine. Also, it comes with an extender cable and rubber corner pads. Im really happy with it.

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

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

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.
