While having dimension of 140 x 140 x 25 mm, which are standard for fans of this form-factor, the SlipStream 140XT fans feature two separate sets of mounting holes, which enable users to install them into blowholes with either 120 mm or 140 mm spaced mounting holes. These new fans are based on sleeve bearings and nine blade impellers, having MTBF of 30,000 hours. SlipStream 140XT fans also feature cable length of 50 cm, making it easy to connect them to a power source even in large enclosures, without the need to use cable extenders.
