Japanese peripherals maker Scythe announced a pair of cost-effective 140
mm fans, the SlipStream 140XT and the 140XT PWM. The 140XT (3-pin,
non-PWM) is available in four variants based on their top speeds, the
500 RPM SM1425XT12SL, the 800 RPM SM1425XT12L, the 1200 RPM SM1425XT12M,
and the 1700 RPM SM1425XT12H. The 140XT PWM (4-pin PWM connector),
comes in just the one flavor, the 1300 RPM SM1425XT12M-P. Both fans
feature the same basic-looking design, measuring 140 x 140 x 25 mm, with
square frames that feature mount-holes for both 140 mm and 120 mm
fan-size standards. Both feature 500 mm-long cables for those hard to
reach headers on your motherboard, and sleeved bearings that yield
30,000 hours MTBF.
The SM1425XT12SL has a speed tolerance level of ±30%, can push 27.2 CFM
of air at its rated speed of 500 RPM, with a noise output of 9.6 dBA.
The SM1425XT12L tolerates ±20%, pushes 43.5 CFM of air, with a noise
output of 14.3 dBA. The SM1425XT12M pushes 65.2 CFM of air, with a noise
output of 23.2 dBA. The SM1425XT12H is the most pushy fan of the lot,
driving 92.4 CFM of air, with 36.4 CFM noise output. The SM1425XT12M-P
pushes a maximum of 70 CFM of air at 1300 RPM, with 24.7 dBA noise
output.
