Alphacool announces ES 80 mm 800-6.000rpm Fan ( 80 mm x 80 mm x 25 mm) - Two Ball Bearing - PWM fan, and SL-15 PWM Fan 600-1800rpm (120 mm 120 mm x 15 mm). The Alphacool ES fans have been specially developed for use in servers and workstations and, unlike usual, do not offer a 2 or 3-pin DC power connection, but a 4-pin PWM control. Unlike classic plain bearing, Alphacool ES fans use a double ball bearing for increased service life under full load. All Alphacool Enterprise fans have multiple protection circuits.

The Alphacool 120 mm SL-15 fan is a special slim fan for use on radiators. With a frame height of only 15 mm, it is particularly suitable for use in ultra-compact housings, also known as SFF housings. Alphacool refrains from using a cheap sleeve bearing and relies directly on a high-quality and durable ball bearing.Data for ES 80 mm
