VapedG13 Reviewed by VapedG13 on . CAN-FAN IS WORKING TOO GOOD!! Hi All, MERRY CHRISTMAS!! Well the temp in my tent never gets above 71, tent is downstairs where the temp in the house is lower (about 4-5 degrees) I keep the house at 70 when home and 64 at night and when away, my therms memory shows that the lowest temp so far was 61.4 and the highest temp was 78 (one day when the filter fan didn't kick on) but normally the temp is right around 70 give or take a degree! example right now the temp in the tent is 70.4 and outside the tent it's 65.8! I'm running Rating: 5
