I've recently started mining and I'm adding more and more equipment to my small mining operation. There are high end GPUs and high end ASIC machines running pretty constantly. The room is slowly gaining temperature as I add more pieces of hardware, this is to be expected because of CFM and all of that. I'm wondering if there are any simple ways to combat this heat increase that are also financially painless. Can I add an Air Conditioning unit to the room or does the method of cooling add too much moisture into the air? Would I be able to combat that moisture with a dehumidifier? How much help would leaving a window open do?
