Adding Usb fans to hood.

[wonroc]

So Sometimes i need to run usb fans in the rear on the aqaurium hood to cool the h2o down on hot days even with the centra l AC on. I have a hygger temp controller for the heater but i havent seen a way to control the fans. I came home the other day and tank was cooled way too much. Has anyone solved this issue and can inform? Thanks

The green inkbird temp controller has a cooling and heating outlet. It controls my heater and fan and I have been happy with it for the past ~5 yrs
