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

Incredibly quiet, typical Noctua quality.

They seem like solid, quiet fans and at a reasonable price

Like every Noctua fan, this one is excellent.

The fan exceeded my expectations, excelent for the price

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.

super quiet fans - you know this already. Cool well too have several Noctua fans in different sizes and series, will continue buying.

These are excellent fans. Unlike their brown counterparts, these are grey and fit most build color schemes quite well. They also contain bearings suitable for industrial applications and are extremely quiet . I dont think Ill own another brand of fan now that Ive experienced the excellence this brand has to offer.

Super quiet and very high performance!

This fan lives up to the Noctua reputation for quiet fans providing good airflow and static pressure. It should serve well as a radiator fan or general purpose case fan.

Really nothing to dislike. Works well and is quiet.
