High speed Alphacool fans in the racks!

The solutions, which come in sets of 120 and 40 mm, have been given PWM control and will tolerate for three days if something inhibits their rotation.

Alphacool ES series fans are specifically designed for servers and workstations, but they have 4-pin, PWM control, so not only can you save energy with them, but you can also stop them completely from software if needed. The novelty double ball bearings are equipped with multiple protection circuits; if the blades are stopped by something, the automatic stop will be initialized and then the engine will try to restart at a lower gear after a few seconds. The point is that the agitator can be obstructed for up to 72 hours without damage, and this is guaranteed by the manufacturer.
