The SF120M measures 120mm x 120mm x 25mm, has a dual ball bearing motor, and delivers up to 62CFM with a maximum air pressure of 2.40mmH2O and a noise level of up to 22dBA.
Sounds pretty good but unfortunately Cooler Master wants $29.99 for this fan.
MasterFan SF120M is an innovation leading fan from Cooler Master that comes with patented anti-vibration motor and damping frame design. The performance, stability, and durability of this fan comes from the industrial grade materials used during the production process. The double ball-bearing reduces the rotational friction for enhanced performance and longevity of the fan. Premium metallic shields are integrated into the fan frame for an industrial grade toughness to the fan. Along with multi-fan connection design and fan speed control, the SF120M is the obvious choice for performance and durability.
