[QUOTE="Pheasant Surprise, post: 5509214, member: 1103"] Dangle control box out the back window for a bit of fresh air eh :cool: They probably didn’t do any heat soak testing on the finished article. Who would run a hedger all day? nah that would never happen :LOL: A lot of control boxes and screens get pretty toasty, especially if they’re in the sun. Typically they’ll have ribbed or finned heatsinking built into the back of the enclosure/screen and that seems to do the trick nicely without needing fans etc. Same sorts of tricks employed for engine, trans etc ECUs, sealed up tight as a drum, no hope of any external air for cooling, but the PCB is attached to a usually alloy enclosure which acts as a giant heatsink for the goodies inside. Plastic sucks if you’re trying to get rid of heat. [/QUOTE]
