Is it 65/63 or 64/73?
Doesn't matter anyways.
You have your cigars boxes and stuff all jammed up against the walls and it's constricting air flow. The thing needs room to breathe.
Remember, these are wine coolers, they aren't cigar coolers. We just re-purpose them.
Regardless of what our desires are, refrigeration requires it's own principles.
One very basic one is that airflow be maintained.
For instance, you can't jam stuff all the way against the back wall of your fridge. The shelves end short and generally have a ledge.
That's what they refer to as idiot-proofing.
When we build out wine coolers, a lot of times we bypass many years of idiot-proofing and make problems.
Make sure you have at least an inch of space in the back of the unit that is completely unobstructed by shelves or boxes and you'll be good to go.
