Unfortunately, my thermostat only has one outlet. I got a cheaper one to hold me through until tax time, when I plan on upgrading everything to the setup I originally had planned. I'll be getting a herpstat then. And no, I sadly don't have an infrared thermometer yet. I'm waiting on payday to pick that up. Its a planned expense, I just ran out of funds in the short time I had to put everything together.
I'll look into getting some of that foam. It was something I was considering to "black out" the back and sides of the enclosure anyway, as I currently have the enclosure sitting right next to my computer. I should probably turn that thing on too, it puts out some decent heat, might help the ambient a bit lol.
