I dont believe there is, but you could rig something up?? If it is something that you already have...You could hook up a fan controller with the three temperature cables. Usually one is for your hard drive, one for CPU, and one for your case. That is for a computer of course, but you could put one of those next to the box to monitor it closely for a day or 2. If its not overly hot then you could just keep that fan out of there? I know thats not practical if you dont have a fan controller with temp outputs on it already, but its just an idea. Maybe if a friend has one they would let you use it?
