I accidentally plugged my CPU fan into the RGB header on my ROG STRIX Z370-E motherboard. I turned on my PC and it started smoking so I immediately shut it down. I couldn't tell where the smoke was coming from but I noticed that I plugged the CPU fan into the wrong header.
Tried plugging it into the correct header and turned the computer back on. Sure enough, the fan no longer works so I'm assuming that's where the smoke came from. I replaced the fan and everything is working fine now. My limited understanding is that the RGB header supplies less power than the fan requires, so why would that have fried the fan instead of just not powering it? Also, is it possible that I damaged anything else on the motherboard by doing that? My computer has been running fine now but I'm guessing that RGB header is probably fried too. I don't have anything to plug in to test it, unfortunately.
