I'm also having temp problems at new apartment
My humidors are also seeing some high temps (77-80 degF), and they are already in the coolest part of my apartment. I have no A/C, and have a fan circulating the air. Can't really leave the windows fully open while wife and I are away at work since they are only a knee-length from the ground walkway.
Do you folks think wrapping a blue ice pack in a towel, and placing it on top of the [desktop-style] humis would help? I have no coolers, and have absolutely no place for one either.
I'm thinking of getting a cheap laptop cooler (twin fans that you place under the laptop) for the sides of the humis to help circulate more air around it.
Only good thing is that my rh is holding steadily at 67-69% throughout the day.
