Humidor Temperature

Hi. I've been smoking cigars for a year and a half now and just recently aquired my first humidor. It is a craftsmen's bench bayport 100 ct. I bought a digital hygrometer and calibrated it, it happens to be dead on with the 75% boveda test. The humidity in my humidor stays at 69 to 71 whenever I check it but the darn temperature is too high. I'll open it in the morning and it will be at 71 and by noon it will have gone up to 75. I live in a dorm room that loves to be 10 degrees hotter than it is outside no matter what. Is there anything I can do short of sticking the humidor inside of my mini fridge set at low? I'd really hate to entertain the thought of getting a beetle infestation. I've searched the internet and I can't find anything meant to maintain temperature of the humidor. There's gotta be something. Thanks
