Case fans aren't the most celebrated computer components, but they are quite widespread, even though they aren't really necessary for a PC to run well.Still, better ventilation means lower in-case temperatures and, thus, higher stability and longer product life.
The two new fans that Scythe has released are called 140XT and the 140XT PWM and are part of the SlipStream line.
The latter has a top rotary speed of 1300 RPM and will speed up or down according to temperature.
The former does not have automatic adjustment, which is why Scythe prepared four versions of it, of 500, 800, 1200 and 1700 RPM.
The noise increases with each level, so PC owners should keep this in mind when browsing.
As for design, Scythe went with a diameter of 140 mm, square frames, mount hold for both 140 and 120 mm fan standards, and cables of 500 mm. The sleeve bearing gives the fans an MTBF of 30,000 hours.
