I do the same swamp cooler, rotating water bottles thing. If you have a wall unit put it in front of that. Beats the hell out of a fan. Even when its 90f+ outside I can keep my carboys at 63-65f.

I will concur with the above, especially the fact that temp control is most critical during ACTIVE fermentation, say the first few days until the kreusen drops, then I usually drain or remove the kettle from the tub. Also a tiny splash of bleach will keep the water in the tub from getting funky and slimy...that's nasty and is nice to avoid, especially a problem during the hot summer months!

Sometimes I will use the swamp chiller to chill from boiling as well...I have a large fridge keezer with the fridge on top, freezer on bottom and I keep around 12, 2 liter soda bottles frozen, that's a lot of ice and will knock a hot batch down to temp quick!

also you might need need to run the fans at night 5 gallons takes alot of energy to eat it up in the ester range. Turning the fan off at night in a water bath should be fine. At least that is my method during the summer. I live in a tent with limited access to elec so i only run the fan in the day time. we have highs of up to 100 F, the ice bottles are a nesectiy.

I don't think I'd trust a basement in the low 60s with S-04. It seems to produce some serious esters if you let it get much higher than 65.

Here's my ghetto lagering set up. I use it for lagering in the winter, and for cooling fermentation in the summer:

A water bath with frozen water bottles rotated in and out, and I'm in business. Of course, this is a cool climate so it's not all that warm here anyway most of the time.
