I would use a pc fan of any size really. They're cheap, quiet, long lasting, and have low power consumption. You really only need a flow of air, it doesn't have to be like a vacuum cleaner in reverse. When trying to push air through basically a 1" hose, PC fans are pretty inefficient in that they allow air to escape back through them if they're pushing more air than can get through the hose. They're not really designed to force air through a space. So a bigger fan doesn't really help too much.

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
