I've got a 5R Pro fixture that I finally figured out had an intermittent fan speed issue that was causing the fixture to overheat and burn out lamps after just a couple shows. Replaced the fan and it runs cooler, out of the danger zone.
But still too close to the danger zone, it gets as high as 200F (93C) even though the ambient temperature is low. I feel like I can hear the fan change speeds when the head flips over. Is that a real thing?
The manual says there's a fan control setting (High, Low, Auto) but my fixture doesn't have it. Do I need to enter a code to see it? Or is it for newer (or older) firmware? I have V2.1
