Do you notice a temp change between what you set your kegerator/keezer to and the beer that comes out? I just tested with a Thermapen and my beer comes out at 58 but the controller is set for 45. I used the Thermapen to make sure the controller was working and it seems to be accurate. One keg on the hump is 2 degrees warmer than the others and I expected it to be since it was higher. But I thought the kegs on the bottom would be closer to the controller temp.
I should say I haven't installed a fan yet so maybe that will help, unless this is typical.
