Hi all, first post. I have made a "Homebrew" temp controller for the egg. I was having trouble finding a fan that would attach well and look nice. I broke down and bought the Pit Viper 10cfm and adapter plate. My problem is I didn't get an adapter from 110 VAC. What is the voltage on the fan? I realize it is DC but cannot find the voltage anywhere. Very great forum, I have learned a bunch.
