Is 70/70 really the “ideal” temperature/humidity mix?
Although “ideal” temperature/humidity for cigars is supposedly, 70° temperature / 70% humidity, your cigars are actually better off at a cooler temperature. 62° to 65° is quite acceptable and will help prevent mold. Mixes of 62°/72%, 63°/68%, even 65°/65% are fine. If you can maintain 70° / 70% with no problems, more power to you. In general, keeping your humidor in a relatively cool spot is a good idea. From my own personal experience I’ve found that an average temperature/relative humidty of 65°/ 68% works best.
