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.
