This has really been a fun experiment. I pulled out the infrared thermometer that I picked years ago when in Korea, new battery and checked the temp on the ice as a base to make sure it was still somewhat calibrated.

I closed up the bedroom earlier so it was d*mn hot with no air flow, around 86-89 and over 90 at the ceiling.

Looking at a 8" exhaust fan with a 3" PVC exhaust against a 6" fan with a 2" outlet. The temps I have read over the past few hours have been fairly consistent, the temps are lower with the 2" outlet but the air flow is a bit less than the other one.

I put 20 pieces of ice in each cooler at 5 PM and with the ambient temps they were putting out air around 74 degrees. To me that is a pretty decent for sleeping.

I'll let them both run through the night (with windows and doors closed) and see how the ice/water is in the morning. My initial thoughts are that they are great when blowing straight on you, I will sleep comfortably tonight, very cheap to build but doubt they could cool anything short of a very small room.

On a side note, the vulca seal product I use on the first one, don't remember the name off the top of my head. It was in a mostly black package with a diagonal cut; anyway it did not react too much with the Styrofoam. The last 2 I did I used the vulca seal and it melted the Styrofoam a bit, not a big deal as you can use a second coat for the exhaust. I used silicon caulk to secure the fan and that had no interaction, so it could be used as well for the exhaust pipe.
