How I activly cool a Tracer4210an

I use a 24v to 12v converter that is powering a temp sensor with a relay on it that will turn on a 12v 120mm computer fan when the controller gets over 30C (I can set it what i want). I got the fan angled so it hits the back heatsink when it runs (which is rare) in sure it will run more as i add panels. I also made a custom lenght eithernet cable that extends the USB adapter to about 40 feet to my server.

I would have used a thermal switch that closes at 80-90F but those are hard to find at that rating. But they are really cheap.
