Theres a pic of my Thermometer , i bought it for like 15 bucks at a hardware store , and im thinking i might put 2 more pc fans in my box , 1 on each side , i have one fan on the bottom blowing air in the box then i think ill put 1 on the left side blowing more air in and one on the right blowing air in , and i have 1 fan on the top back blowing air out , but i think all that might be too much air? i think lol
