84 hot end and 73 cool end. I just got a temp gun today and found my hottest surface temp to be 87. My thermostat is set at 89 on the heat tape. My room temps are about 67. Not much I can do about my room temps until my living arangments change. I'm going to raise my thermostat to 92 and see what that does in my boaphile ballroom rack. Any advice on this?
