Hi Everyone !
I’m working on a cheap way to make sure everything is cooled down and went for a direct cooling of the Esc (a VESC 4.12 in my case). I’ve bought a supposedly “non conductive” thermal fluid (conductivity < 2µs/cm) https://www.amazon.fr/gp/product/B00AXW07TE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1.
I’ve put the Vesc in a casing filled with this fluid. Unfortunately, eventhough everything worked fine without fluid poored in, as soon as I put the liquid, it stopped working.
What I don’t understand: this fluid is meant for PC watercooling and some use it to fill an aquarium with it and drop ALL the computer’s components on it, so it should work in my case too right ? Maybe it only works with low power ?
After removing the liquid and drying the Vesc, everything works again, meaning there is no short and the PCB isi not damaged.
Does anybody have any idea on what could have happened ?
