As the title says, I am not getting verry good contact on the fan shim PCB against the GPIO pins. The fan itself works but because the contact isn’t good enough, the LED on the shim PCB cant be controlled. I have the Raspberry Pi 4 sitting in the pibow case. Does anyone have any tips on how to ensure that there is sufficient contact between to two components?
Its not ideal but you could try plugging a female header in on top of the fan shim.
Or solder the fan shim to a female header. It will raise it up a bit though’
Take a good look at the male pins on your Pi’s GPIO header. Look down the length for any pins the fan shim uses that are bent. even very slightly. Then carefully straighten them if they are bent
