After realising my mirror is 2" thick, I figured I may have thermal problems while observing so decided to get the fans on my dob working. It has an RCA jack, but the question what do I need to get it working?
From what I've researched, a 12V power supply will work but not sure what type. Looking at the DSE website I found this:
