Wish this was available when I built my house. Way nicer than the earlier metal version. Plenty of option for configuraion. Only improvement I can think of would be to add small magnets to hold the cover, vice plastic tabs. May add those myself. Excellent option if you want a bit more space behind your flat panel TV for a switch, Roku, Nuc etc. It fits well with our furniture setup. The quality really stands out.
I've been using this in my entertainment center for over 2 years and it is still doing a great job. I have it controlling (4) 120mm fans total through a (2) splitters.
This controller is set to power on the fans at 87* and I set a high temp of 100*. I love the auto feature since my electronics are in an enclosure and I don't have to worry about them overheating.
It takes a little tinkering to find the right temperatures to set, my setup stays at 83* when everything is on standby. So be careful when setting the alarm temp so it won't stay on all night. It fits well with our furniture setup.
