Aerocool DeadSilence Series Fans Now Available

Aerocool began selling its DeadSilence line of 120 mm and 140 mm fans, which are designed to strike a balance between performance and noise output. Available in four color options - blue, red, white, and gray, these fans are characterized by vibration-dampening frames, and impellers with rubberized layers that absorb noise caused by whipping through the air on one side, and golf-ball dimples on the other. The inner edges of the frame have "silencer blocks" that absorb noise caused by whiplash of the edges of the impeller. The motors of these fans feature fluid dynamic bearings, that offer greater lifespan.

By the numbers, the 120 mm variant spins around the 1,500 RPM mark when supplied with 12V, and around the 1,100 RPM mark when supplied with 7V. At its top speed, it pushes 81.5 CFM (138.1 m³/h) of air, with a company-tested noise output of 23.1 dBA. At 1,100 RPM, it pushes 62.5 CFM (105.9 m³/h) of air, with 14.8 dBA noise output. The 140 mm variant, on the other hand, offers similar rotational speeds at the given voltages, but push greater amounts of air, since they're bigger. At 1,500 RPM, it pushes 93.4 CFM (158.3 m³/h) of air, with 23.4 dBA noise output, and 71.2 CFM (120.7 m³/h) at 1,100 RPM, with 15.5 dBA noise output.

Kind of pointless when most of the noise from fans still come from air going trough the vents and vibration on the case caused by the fan spinning.

Go go go Dead Space.....uhhh I mean Dead silence :) I would give a spin to one of those if they come available around. I am sure they won't cost as much as Noctua's :)

Sweet, been waiting for these. These or Phanteks 140mm will be replacing my 750D stock 140mm fans.

Thats why most of thr frame is rubber, to transmit less vibrations to the case.

@btarunr any word on pricing?

I used dozens and always satisfied for the $5 they cost and the air pressure they make.

They were the first fans I ever bought and they are still my favorites it's just too bad they don't have them in the color scheme I want. (orange translucent blades + white LEDs) Though I might go back to using them since I'm annoyed at how damn loud the Xigmatek XAFs are at full speed.

Finally a product from competitors that can at least come closer to Noiseblocker fans. I love their Multiframe fans. Zero vibrations due to silicone corners, very low air noise and pretty much zero motor noise. I'd love to hear these from Aerocool if they are really better. Any info on the bearings used?

EDIT:
I see it's FDB on their webpage. That's good as well.

It's a very legitimate design, similar concepts have been used in luxury automobiles for nearly 2 decades, possibly longer.

I'm referring to the blocks on the edge and the dots on the blades themselves. Nice to see there is still some "engineering" in this world.
