Temp control in humidors

[Steve OB]

I am new to the forum. I( have read many threads about what temperature and RH should be (70/70%). I was wondering, how does one control the temperature in cooler humidors and most desktop wood box humis? I am converting a Magic Chef wine cooler into a humidor. It will hold about 22 boxes of my favorite smokes (Oliva Serie V Churchhills) I know that compressor driven cooling systems tend to suck the humidity out of the box, so I don't intend to use the cooling system. I will unplug it. I intend to use beads to control RH. I learned that the mean annual RH where I live (San Diego) is 69%. The unit will be inside. In the summer the temp inside varies between 65 and 75 (no A/C). That means the temp inside the unit will be 65-75. Occasionally, it gets up to 80, but it doesn't last long. The winters average between 60-65 indoors. If I maintain a 70% RH inside the unit, will my 3 cigars be OK?
