Noctua NF-S12B redux-1200 PWM, High Performance Cooling Fan, 4-Pin, 1200 RPM (120mm, Grey)

It Noctua; just what you would expect.

This thing moves some air, no doubt. I have Corsair HD-series intake fans on my case and use this one as the exhaust fan - I can watch temps dip when it fires up. At up max speed, its almost silent. Anything under 1000rpm and it is silent. Highly recommended if you need to move some air.

Love it.

I didnt really believe the hype on Noctua fans, but after installing 2 of these Im a believer.

I want a fan to last a long time 6 year warrante.

I bought four of these to replace my two loud stock Corsair case fans along with the Noctua anti-vibration pads. These run more quiet and at a lower tone than the high pitch of my old fans. The side mounted fan should help with my GPU thermals, and I installed two more intakes at front and bottom of the case, with one exhaust out the rear. Ill pick up a fifth fan for top exhaust.

The Redux fans are every bit as quiet as Noctuas premium fans and seem to move equal amounts of air. All at about half the price.

These fans were a great improvement over my Yate Loons. Those were 8 years old, so that may have been the cause. Not silent, but a substantial difference. The only reason this is 4 stars is because the corners do not match the image and thus the chromax anti-vibration rubber mounts I purchased do not fit. They have two long rubber extensions to go through the two outer holes (while the screw goes through the center hole), but these two holes dont exist on the fans I received. I had to jerry-rig the things, cutting off the extensions and 2 mm from each end to make them somewhat fit. Very strange.

Even their less expensive models are great.

Nice rear fan. Its quiet and does move air, great choice for quiet PC system. Since I dont need much of air pressure to pull the heat out of case, this type of fan become top choice. You can lower the rpm by software if you still sense noise.
