The Aerocool DS 120mm x 25mm Extreme Cooling Fan is one of world’s most silence fans with breakthrough technology and innovation. These fans come with dual-layered fan blades - combination of plastic and rubber fan blades to absorb “wind” noise. The “Golf Ball” surface design on the back rubber side of the fan blades is to minimize the air turbulence. The fan frame incorporates four silencer blocks and anti-vibration rubber pads on each mounting hole. Along with the silent treatment these fans also have a super low starting voltage of 3V making them great for controllers.

I put 6 of these into my new PC build, and they rock. I can''t hear my PC with my headphones on, and my temps are holding steady at 30 Celsius idle, and I peaked at 61 Celsius doing some benchmarking. These are also very attractive and light weight. I''ve not heard any rattle yet. Great, great product!

Aerocool has made another fan (out of me that is)! Without a doubt, a significant sound improvement from my previous fan and although I don''t have a meter to determine the dba of this fan, it''s quite silent with a slight hum. Amazed at how this moves a ton of air without the mini-jet noise so well worth the cost. Can''t imagine going back to older fan technology with these on the market.
