Hi everyone! I’m new to it, so this is going to be a very basic question. I just set up my first cabinet, and I'm not sure if I'm overthinking this, but I got two cooling fans and I ran into a couple of issues. First, the USB cord is not long enough to reach outside the hole I drilled on the bottom of the cabinet, so I would need a USB extension cord. The cord also has that switch, speed controller in the middle of the cord. I was asking AI for help with this, and it basically said that I would need to make sure that this USB connection and the controller are both properly covered, “ideally with marine grade heat shrinking tubes”, because of the humidity in there. But then I look at pictures of other people's setups, and I don't really see any of that. Am I overthinking this? Should this really be a concern? I'm hoping to keep the humidity in there between 70 and 80 percent. Please let me know what you think. How do you have yours set up? Thank you!
