They didn't mean freeze the humi - they meant freeze the sticks!
I live in Southern Georgia and refuse to pay a $250 electric bill, so during the 8 months of summer I usually keep my AC at 85 while I'm gone, and 75 once I get home. I used to freak out about my cigars getting beetles too (they actually usually start hatching above 80). Then I just realized "You know what, there's nothing I can do about this." So I stopped panicking.
In the last 2 years my cigars have spent about 8 months out of the year above 75 degrees. I just check on a regular (weekly) basis for beetle holes. Only had 1 cigar ever, and I froze then smoked it later.
If you don't have beetles, and you like how your cigars are smoking, don't worry so much about temp or humidity. If your cigars taste great, then it's all good. Too much worrying takes away from the relaxation of the hobby!
