NoctuaNF-A15 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Bought this because my PC build was running a but too warm. Adding this fan to the case to exhaust the heat lowered the CPU temperature by about 10°C

Never bought Noctua before and sure enough they are as good as everyone has said. High quality and quite. I bought this Case Fan as a suppliment to the D-15 cooler (which comes with two of these fans).I have two fans pulling air inside the case from the front and one in the middle of the dual radiators cooling block, all fans on one CPU fan header for one point of control depending on the CPU temperature, all fans working together.No need for the in-line lower-RPM adapters, I took them all off and decided that the fan curves that I set, should decide if the fans go to full speed if needs be on the rare occasion the CPU goes over 95 (its an intel 8 core at 4.5).Brilliant.

Easy to install used a second fan to support their threadripper cooler.Mounted in Fractal case it is as quiet and efficient as one can ask for.Well pleased. Contacted their tecnical to to confirm the cooler would be fine on Threadripper 3rd generation good speedy response.

One of my bug bears is paying a premium price and not getting any customer services. I emailed them as one of the fans was damaged,The fan itself is a beast. This is a lot bigger than I expected and just about fits in my mid tower. 2 of the memory slots can be used on used but the other 2 on the atx board maybe too close to the fan. The fan at the front I fitted further to the right so it’s not near the ram. The fan slso,make it difficult to uncoil your graphics card as it’s hard to get to the clip. One of my m2 slots has been taken away from me also.Cooling wise this is brilliant and seems to keep my amd 7900x3d cool. The maximum the processor has reached is 76c and the processor is known to give out loads of heat. The fan is quiet and has no vibration and is really good quality. This would have had 4 stars as the fan is large and I think more suited to an e-atx.Edit: I broke a fan by fitting it the wrong way. Noctua were a little slow getting back to me. They are replacing the fan as a gesture of goodwill. Great customer services.

use 2 of these to cool my zalman cnps14 heatsink and it does a great job and almost silent most of the time even when fan is up full it is not too noisy.specs msi z87 mpower , intel 4770k oc to 4.2 ghz idle 30 to 33 degs full prime 95 58 to 60 deg, Corsair Carbide Series Air 540 High Airflow ATX Cube Case. asus 6950 graphics.

Another excellent fan from Noctua. I’v used it to replace the stock 14 cm fan on my Noctua twin towers and it does a bit difference reducing the noise inside my PC. The temperatures of the cpu in idle or under stress are the same but the RPM of the fan has dropped from 1100-1200 constant to as low as 380 in idle and 600-700 under load.It is an excellent upgrade if you’re pc is noisy

this was bought for the front intake on my zalman z11 case but sadly does not fit so had to use as a bottom intake. this fan just oozes quality from the minute you touch it you know noctua have designed these with perfection in mind. even at low rpm this fan pushes a lot of air, and at max rpm is the quietest fan in my case. my gentle typhoon makes more noise.amazing product just make sure it will fit as the dimensions are 140x150.

Bought this to use it as chassis fan on Silverstone FT03 Mini to replace the Air Penetrator fan that it came with it (because of noise). Its definitely one of the quietest fan I have ever used and the pressure of wind is quiet impressive too. However it does not have the distance (or penetration!) as Air penetrator does so I feel less wind coming out of the case at the top with NF-A15. (FT03-Mini only has exhaust at the top of the case) But because its rather packed inside the effect of the chassis fan is rather limited so it does not effect the cooling so much. Besides because there isn't much of noise I can keep it on at 60% duty cycle even at low temperature so that I can continually keep my components cool and thus, hopefully, extend its life.
