If the tower fan is the noisy kind, check whether it is the noise keeping you up rather than the heat. I swapped mine for a slower, larger-bladed fan on a lower setting and slept better at the same room temperature, purely because it stopped whining at 3am.

Home recording in a bedroom with bad acoustics and decent headphones. Gain staging, mixing on a budget, and knowing when a track is finished.
