I'm guessing you stress about keeping the temp so low because you're worried about beetles?
When tobacco is fermented, the internal bale temp reaches over 118 degrees. Proteins denature at 106 degrees. That means beetle eggs should all die in the process.
That's why when we get cc's that never see any air conditioning or cooling whatsoever, seldom if ever do we see any beetles.
It's because their process and product absolutely requires that the tobacco be cured properly and carefully. If not, the ambient temperature in their storage and processing would be overrun with beetles.
The only time a beetle egg gets through is when the bales aren't pulled apart and resorted and restacked inside out often enough or completely enough.
In all the years I've smoked, and all the thousands of cigars that have passed through me, I've seen exactly one beetled cigar, and it came that way.
I keep a cabinet at 75 degrees all summer.
I keep a humidor outside on the back porch all summer.
I keep a humidor in my shed all summer. (It gets brutally hot in there at times.)
Not once have I ever hatched a beetle.
All that was to get to this...
I hate smoking cold cigars. I've watched all this stuff just so I'd be comfortable keeping my cigars at any temperature.
I keep my vino at 70 degrees, because that's as high as I can get it to go.

Still no beetles, and the cigars are so much more inviting.
