Silent 120mm Fans

post #1 of 9
Thread Starter 
I am building a water cooled system soon and I want it to be silent. I will have a 4 fan radiator installed in the top of my case and I wanted some silent fans. These fans are 8-12 dB but they are low CFM. Anyone know what a good dB is for silence or very low noise?

Noctuas (54 CFM) and SilenX (18dB at 72CFM) make quiet fans with a decent CFM. i bought a SilenX and it was a little louder than 18dB but still very quiet. put these on a fan controller and you could adjust them as you pleaser. 20 bucks each for both brands. i heard yate loon has some quiet ones, but low CFM. lower than 20dB is great though. 25dB is about whisper quiet.

Doesn't SilenX take their db readings from 10 meters out?

Stay away from Silenx, they don't test their fan noise the same and actually produce more noise on radiators than many others.

One of the quietest fans I've ever used:

Vapors testing had the Silenx fans nearly in last place for cfm vs noise performance even in open air...yikes!

And similarly in last on a radiator.


Yate loons are really hard to beat, particularly the curve blade types from Petra's.

Fans definately don't fit the old you get what you pay for scenario. Granted loons are just a sleeve bearing, but they work and hold up pretty well. The higher speed fans a different story though.

Petra's Tech Shop. Yate Loons. Conversation ended haha.
I purchased 5 120mm's thinking I would have 2 Extra but ended up needing 2 more. Best Fans I have ever purchased. They are near silent and have amazing CFM even when maxed. I have trouble finding out if the non-visible ones are on because the other fans in the case drown them out and I have to feel for air flow. These are mediums maxed at 12v.

Noctua NF-P12 currently have the best noise to CFM ratio. They're amazing fans!

Noctua's if price is no object and you can handle the color scheme.....otherwise Yate loons are it.
