Small temp swings or set heater higher?

[lastlight]

Yeah it's funny because when it started getting hot here I looked all over on the thermostat for a fan switch. I did that when I had a house all the time to freshen things up. I can't see anything on there to do that but maybe I'm an idiot. I can only get the furnace to blow when it's heating?

I'm going to get fans today for a start but I'm still thinking thicker drapes in the kitchen would help out a lot. If someone with small fans can suggest either a 2 fan or 4 fan unit for a 34g I'd appreciate it.
