Noctua NF-S12B redux-1200, High Performance Cooling Fan, 3-Pin, 1200 RPM (120mm, Grey)

No air flow

If your case fan is noisy, just replace it with this one. It is super quiet. Your computer shouldnt sound like a jet taking off.

.... and a good one too

I think this is a good fan, but its not perfect. As part of the redux line from Noctua, its got a more basic package. I think these fans are probably not the best value in the about $14 dollar or so range. But I was going with a gray & silver build so they are really nice. I think asthetically they look very nice. It does, due to its design, move air well through open spaces. I use Noctuas low noise adapter with this and it works well, and is very quiet at about 900RPM or so. At stock speed I think its a little loud, but thats just me and your mileage may vary. As with other Noctua fans, it makes a low pitched hum. In all, it works for me and I look forward to many years of service with it.

works fine

This fan is an amazing replacement for any fan, it is super quiet, and it has lasted me almost a year now! Worth the $20 for sure!

Fans work great and pretty damb quiet.

Good fan just wish it came in all black. Its quiet and works very well. No issues. I would order it again. Its a fan and blows air.

Had to replace a stock case fan in my Cooler Master Cosmos (2007) case. Installed without difficulty; running silently. Over the years, all the fans Ive installed were made by Noctua - always had top reviews at the time I needed them. Totally recommend Noctua.

so far they have done exactly what they are supposed to do. i did end up purchasing the vibrations isolators. there really wasnt any excess vibration to begin with, but because of the contruction of my case, i could hear them. after those went on there was no noticeable vibration noise or even the feeling of vibration coming from the case.
