I would have to say yes. I drilled a 2 1/4" hole in the lid of the chest freezer. I placed a 1 1/4" outside diameter tube into the blower and fed it 3/4 of the way up the tower (just below the tap actually) I cut a small hole in the hose and fed the beer line inside the 1 1/4" hose up the tower to the tap. When I place my hand over the hole on the underside of the lid I feel a decent airflow coming out. I also tested the temp inside the hose where I fed the beer line through (which is still inside the chest). The temp there was about 40 degrees also. That's why I think the blower may be heating the air slightly.
