Noctua NF-A20 PWM, Premium Quiet Fan, 4-Pin (200x30mm, Brown)

Pros:-Silent due to pushing good air at low RPMs-comes with an extension and even a low noise adapter to force its max RPM to be lower if needed-Price isn't bad considering the qualityCons:-Very thick which can cause an issue in some casesAwesome quality fan that I have no issues recommending to people if that are in the market for a good quality low noise fan.Side note for fitting in the Cooler Master h500 case:It fits in the top if you remove the rubber bits on the corner (other wise they'll fold due to pushing), then line it up so when you shove it in then it'll basically be where the holes are lol Yes I said shove it in. You have to force it in, but no worries it won't break the case nor the fan. Secure it with screws in the fan box instead of the silicone options. The Case wasn't made to accommodate a 200mm of this thickness, but it will still work. Just make sure you have the fan oriented the right direction ahead of time so you can have enough room to plug it in, though it does come with a nice extension that I did use for tidy cabling purposes.I did not try the front fan section since there are no mounting standards for 200mm fans. Since the top was a very tight squeeze, there was obviously no planning around making Noctua's 200mm fans fit.

- I was sick of a hearing an 300k mile Camry trying to get into 5th sitting under the desk. (That'sright, that's where the box belongs, not on top right next to your screen with the design aesthetic of a TijuanaNightclub.) Noctua fans are QUIET. I CANNOT HEAR MY BOX AT ALL ANYMORE AT IDLE, and even at full RPMthey are so much more bearable, and move more air, than any other brand that I have had. Pretty muchthe quietest case fans on the market.- The build quality is exceptional. Noctua specializes in case fans, and they make them better than anyone. Thebest bearing setup. The best fin design. The tough plastic. The tightest assembly. Looong Lifespans.- PWM control option for all models. Set the curve, ride the silence, or unleash the fury.- Braided cord, extensions, and y adapter included. Also silicone standoffs and stainless grubs. Nice.- The packaging. You can feel the love these people put into their product just oogling the cardboard it comes in.- I like the look of the dreaded Noctua Beige + Brown. It's pure function over form. Extreme efficiency andutilitarianism.

This is a perfect drop in replacement for the stock 200 mm fan in the Thermaltake Core V1. No modifications to the case or fan were required.Performance and Quality. The fan is well built, attractive and performs excellently, as one would expect from Noctua. Even at full speed, the fan is barely audible - much quieter than my stock Intel CPU fan even at idle speeds. As a PWM fan, of course, it doesn't have to run at full speed. I'm normally running it at about 60% and I never even hear it. It effectively cools my system built on an Intel 65W Core i5 running at stock speeds, 16 GB RAM, Samsung 970 Plus M.2 SSD and 2 Samsung 860 SATA SSDs.Installation: Use the inner set of mounting holes on the Noctua NF-A-20. They align perfectly with the mounting holes used for the stock fan and make it possible to use the original mounting screws that came with the case. The Noctua fan is a hair thicker than the stock fan, potentially bumping it up against the front cover of the case. I removed the rubber vibration dampers from the Noctua fan just to be sure I had sufficient clearance. Absolutely no issues with vibration noise. I mounted the fan so that the wiring passed through front wall of the of the case by the small rectangular cutout at the bottom. It was close, but the wiring can enter this way with no pinching or rubbing of the wires. If you are happy with the wires entering through the top of the case, that path is wide open. Mounting the fan with the wiring on the side, though, may pinch the wires. Mounting the fan as I did, I needed the included 4 pin extension cable to reach the fan header on my motherboard.

I bought this as a replacement for the stock fan in my CM Trooper since it started making a horrible grinding noise which kept getting worse over the last few months.I was hesitant to buy this particular fan due to many reviews stating this fan being oversized and not fitting, plus my case wasn't listed on the official compatibility table either.But there are not a lot of good options for 200mm fans and most had some kind of flaw.The Noctua's are touted as the best on the market and the only flaw seemed to be its size. So I went ahead and chanced it, with the plan to return it for 2 smaller fans if it didn't fit.To my surprise, it fit great! The screw holes were only slightly off and I was able to install with no issues.The fan comes with several different mounting options - standard mounting screws and also 2 styles of anti-vibration mounts. I went with the anti-vibration mounts which made installation even easier since you just pull the flexible strands thru the holes, no tools required. It took longer to figure out how to take my case apart to get to the top fan than actually installing it.Turned on the PC and no more grinding sound! I'm about a week in, so will be interesting to see how things are a month/year down the road, but so far this thing is quiet and provides great airflow. Definitely lives up to its reputation.

I learned of Noctua when building my pc and had to try a few fans. I already owned a bunch of low price decent fans. I upgraded my water cooling since I was running a I9 13 series chip and needed a little more cooling in my MicroATX case... since I maxed out all my options with having a 240 and 280 radiator I only had two intake fans... My solution was to cut out a spot for the NF-A20 because of its massive static pressure and air flow @ near silent. Now my Rx 580 never turns on doing office stuff running a 4k and 1080 monitors. Plus I did the math and the power usage on this thing compared to any other 200mm fan is saving $40 per year. The thing pays for itself in half a year!!
