Passive Cooling for the TX Enclosure
After running the receiver station in its new enclosure for almost a week now, I had noticed that the top of the case was a little warm on the rear LHS, which is right above the heatsink on the powersupply. Nothing too concerning, but warm none the less. So I decided to cut open a 52mm hole and install a 60mm fan guard. For now it is merely an air vent, as the case has absolutely no ventilation otherwise. I think this should be enough to solve the problem. If I cut over to battery power and run down the battery somewhat, and also turn on the LCD backlight, the power supply heatsink runs at about 38 degrees when the chargig circuit comes in. So not too bad. If it is an issue next summertime, I'll simply install a 60mm fan directly below this fan guard.
