Maybe fried my mobo. Is the firmware thermal security feature really this abysmal?
I'm used to working with Mini-PCs I moved my trusted setup of usb C hub, powerbank and booted steamdeck mobo with fresh nvme drive. I got to Ventoy menu to select my ISO to install linux, but my keyboards weren't working. I tried wireless as well as simple wired one. (some boards don't like wireless)
I couldn't get it to work so I rebooted, suddenly I got 3 reboots without screen popup, finally screen showed up, I got graphical glitch of stripes with noise and different colors, Fan turned off, and the GPU kept drawing power so the board started heating up. I Unplugged it but this is really stupid design.
They must have a bug in firmware where the fan stops spinning but the chip doesn't cut the powerdraw so it keeps heating up.
USB-C spec is really advanced and due to the handshake, the device shouldn't accept any other voltage than what it can't handle so that part is secure.
