turning on the parts fan causes all temperature measurements to go haywire #83

When I turn on the parts fan, the temperatures for the heated bed, extruder, raspberry pi, and the mcu start going up or down or jumping. Each percent I increase the parts fan causes changes in the temperature readings. Sometimes, they jump so high or drop so low that Klipper shuts down. The fan itself doesn't come on. In fact, this occurs even when the fan is not attached to the Spider. That means that something is happening on the board itself (or, I suppose in the firmware).

Purchased Spider board on Aliexpress in the Fysetc store. I'm running the latest Klipper and RatOS. Thank you.

I rewired the parts fan into a vacant extruder port and now it works as expected. But, that doesn't solve the problem, it just works around it. I think I may have a shorted out board.
