Question AIO not detected in bios/no fan spin

[Blok13]

My arctic cooler randomly turned off today while i was playing a game and it caused my cpu to overheat and shut down. I tried seating the cables and checking bios but the cpu fan in bios says none detected. I had a similar issue a few months ago but was able to fix it but switching which cable was in which slot. it is a Arctic Liquid Freezer II 240 connected to my ASRock X570 PG Velocita ATX AM4 Motherboard. Any ideas or help would be great.

So what turned off? The fans? The pump? Everything?

Try connecting an extra case or CPU cooler fan to the CPU_FAN header. If it won't work then it's likely a problem with the PWM circuit on the board. If it works, then it's probably a failure of the cooler electronics in some way, which really doesn't matter in regard to WHAT failed on it, because if any part of the cooler isn't working the whole thing isn't working and needs to be warrantied or replaced.
