Your cubic feet area it's 384 cf and a 6" or 8" fan will cover the ventillation area .

You have only 384 c/f and I would go with the bigger of the two... The 110 or bigger.. But what I would look at is the quiet rating of the fan. I made the mistake of not doing that and noise it made is unnerving.GL

I wasn't too impressed with the 80...go with the 110...

Both will replace the air in roughly 4 minutes.. Like noted before the sound may be your biggest factor here.

80 would probably do it, but 110 would do it quicker. Here's a calculator.
