I would like people on the forum to help me choose what would be the best option to go for to control my environment.

The sms twin fan control looks pretty nice. Funny I was looking for a control that also controls fan speed. great for intake when the ambient temp is cooler outside. The evolution is what I would get based on reading about it. Nice to control everything on one control.

true thats what i have my eyes set on for now but would prefer feedback from users though

bump any body use ruck fans with built in controllers?

what are they compared with separate fan controllers?

no one using ruck temp controlled fans?
