Works great, but man is it big

I am a small neighborhood WISP and I have several weatherproof boxes that contain routers and other equipment. With summer approaching, I was worried about heat and cooling. But, I didn't want a fan on 24/7. I bought a computer case fan as well as this temperature-controlled fan box. It does exactly what I need. My only complaint is it's pretty big; much larger than I thought it would be, especially for the low voltage output. With that said, so far it has worked flawlessly.
