What Running 55 GPUs in One Room Taught Me About PC Cooling
Running 55 RTX 3080s and RTX 3090s simultaneously in a 12×12 bedroom in South Florida generates between 12,000 and 17,000 watts of continuous heat. Standard fans accomplished almost nothing because fans move air but do not remove heat from a room. The solution was a 1.5-ton ductless mini split blowing cold air at GPU level combined with a whole-house exhaust window fan pulling hot air out at ceiling level. That complete thermal loop is the foundation of everything on this site. Read the full story.
