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

These fans are fan-tastic as I heard. Great cooling power and low noise. Only note that this is 3 pins model.

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.

I have a sleeper build that I utilized both this fan add well as its big brother. Works well and cant complain with noise. Good product.

Airflow is great, very pleased compared to the old fans I replaced. Fans feel rock solid too, not flimsy at all.

These come with such great add-ons. The extension cables and power dampener (spin slowing effect) cables can be mixed and matched with your existing cables (use these as the base, for instance). I daisy chained some door and top exhaust additions with no problem. They have been running for months now just fine.

Only about 1/2 the air flow of the previous fans that were 5 times louder. No overheating so far.

I love these. Theyre quiet and last forever.

great fan, works well and very quiet

I purchased this fan to replace a garbage stock fan. The fan performs much better than the stock fan. It is quiet and moves a lot of air. I am currently using it as an intake fan attached to a Corsair all-in-one water cooler (a different Noctua is used for exhaust).

VERY quiet compared to my other fans, and the high flow blade design is a great option. It runs at reasonably high speeds, so its quietness is not created just by reducing the maximum speed. And its a reasonable price for a premium fan. I expect Ill stock up on these for my next build!
