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

Its a Noctua Fan so it just works great & runs quiet.

Fan works fine I have been using this for a few weeks now. Hopefully it will last as long as Noctua claims.

Extremely smooth, Incredibly silent.!

Fantastic quality fan that runs super quiet. Im glad I found this lower end line of fans from Noctua as it saved just a tad bit of money and I actually like the color way better than their tan/brown combos on the more expensive versions.

Fast and quiet... like a ninja.

Its Noctua, need I say more?

I used these to replace the two on the radiator for my CPU that were starting to make noise. Theyre virtually silent even at 100% power. They move air like a fan should. Temps are as low as with the stock fans, so good in my book.

Great fan for the price. Added a 120mm and a 92mm replacing the stock case fans. Sounds better and moves way more air. The cable is extremely long and I had to get creative with cable management to avoid a sloppy look.

Great fan, updating my old cases 3Pin fans to proper PWM. Silent, look acceptable in a black case.

Very quiet but do not move as much air as I had hopped but the silence makes up for this
