NZXT AER P 140mm - Winglet Designed Fan Blades - Fluid Dynamic Bearings - PWM Static Pressure Fans - Gaming Computer Fan

I've gone through a bunch of fans in my time, but I am very pleased with these NZXT 140MM fans. They move air quietly in just about every configuration I've put them in. I currently have 2 running as intakes for one case and they keep the temps in check easily without having to go full speed. In my gaming rig, I've got 3 of them pulling air in to my Kraken X73 cooling my graphics card, and another two exhausting out the top. The only thing I could say bad about them was they were expensive when I got the first two; The other 3 I got for $10 each, which is a steal in my book!

For performance, I used this particular one as a top exhaust fan. I have the speeds adjusted for GPU temperature. When idle, my system temperatures have plenty of headroom, and the fans are silent. They keep everyday PC performance where it needs to be - and quietly. When gaming, I may be overshooting my speeds precautiously. Four total fans get pretty loud - within reason - at around 1,500 RPM x4. However, they definitely move air.The RGB setup for NZXT was kind of a pain - connecting to the controller box, figuring out which of the ten wires works in what direction, and then figuring out how you can cable it all. A little annoying that I had to set up both color and power for all four fans. But I understand there are limitations in engineering, etc...I would knock the app if anything. My GPU temps were well understated (62c v 84c true). Now I cannot even see the GPU temp at all, so I had to reconfigure my fan program to anything but the most important reason I want them running. I cannot find a fix on this anywhere I look.Color scheming is pretty customizable. There are also some dynamic variables (CPU temp, GPU, temp to color ranges, etc...). Where I was annoyed: if you daisy chain your color control cable, anything dependent to the first fan (or light) can only be given a different color if you change each individual LED color. This makes trial-and-error a way longer than necessary process.Overall though - I think very good. No regrets. If anyone is buying JUST the fan, I have no reason to believe anything under perfect.

I bought a 3 pack to replace the 2 front fans and the back fan on my Corsair case ever since some of the fan stopped working. I'm not sure if it's because of my case but the screws weren't cooperating with the fan so that's why I rated the installation 3 out of 5. After that was handled, though, it functioned properly and has kept my PC very nice and cool. You can barely hear the fans spinning and white blades looks alright.

very pleased of these fans they are nearly dead silent and only about 80% you will start hearing a little hum but the amount of air they move is crazy
