Yeah, I'm not having any joy with the big coolers with a cool room and ductwork either, whereas making a hot loop with the industrial heaters and ducting is working perfectly fine.
Some weird is going on with the cooling, those big coolers just dont seem to be cooling correctly, its real hard to drop the temperature significantly when using them to create usable cool air for the ducts. Heaters on the other hand, plonk one down in an 8x8 Room, add an intake duct, and outlets where you need 'em, crank that thing up to +100 and you get tons of heat pumping.
