The SickleFlow 120 (R4-C2R-20AC-GP)
is probably the most popular of the three Cooler Master models included into this review. It comes in a
transparent plastic pack that protects it against any hazards and allows to see the fan without opening the package.
The accessories are limited to a PATA power adapter and four self-tipping screws.
The fan is manufactured in China and has a recommended price of $7. The warranty period is 1 year. This fan is employed in Cooler Master’s V8, V10, GeminII and other coolers as well as in system cases.
To me, the SickleFlow looks gorgeous. Its glossy black frame is a perfect match to the 9-blade impeller with sickle-shaped opaque blades.
The impeller and electromotor are 113 and 40 millimeters in diameter, respectively. Three of the fan spokes are 5 millimeters wide; the cable spoke is 12 millimeters wide.
There are two ribs on the interior of the frame. The gap between the impeller and the frame is about 3 millimeters.
This fan has a constant speed of 2000 RPM. Its air flow of 69.7 CFM is somewhat lower compared to the previous two fans from Cooler Master at the same speed. Its noise level is specified to be a highly implausible 19 dBA. The static pressure is 22.94 millimeters of water, which is lower than that of the BladeMaster and Excalibur.
The start-up voltage of this fan proved to be the lowest among the tested products at only 2.4 volts. Its power consumption is less than 2.9 watts, i.e. lower than the specified 4.2 watts. The sleeve bearing is rated for 40,000 hours of operation. The fan’s 3-wire cable is very short. It’s only 290 millimeters. There is a PATA power adapter in the box but it deprives the user of the monitoring and speed control features. The SickleFlow weighs 113 millimeters.
never thought of running them together; Furmark & Prime95... Thanks for the tip. 
Never used it before!
