Previously been using a Lampton F5 v2 for the past 8 years but recently one of the buttons has become unreliable despite my attempts at repairing it. That's where the Askasa FC Six comes in.
Despite being a little slow, around 2-3 seconds, when making adjustments it's a good solid fan controller.
LED's are a little too bright but I swapped out to higher value resistors to compensate for this.
It can handle 8 Noctua NF-A12x25, four per channel, easily.
