I'm a new user and have recently purchase a Pi4, I am using it for games emulation and seeing as it gets hot I bought a fanshim, which is installed on the GPIO pins, it works great and once booted up there is a service that runs switching it on and off at the desired temp threshold.
On to my actual issue, when the pi is in standby mode this fan runs continuously and the only way to stop it is to pull the usb-c power cable out. I've spend the past few days researching how to add a power switch to the Pi4 to turn off the power when not in use. I am using the official power adaptor and where its plugged in behind the TV is not easily accessible to switch the power off at the outlet.
I've seen on earlier models using the micro usb connector that inline switches are available but nothing like that seems to be available for usb-c due to the way its wired. Any pointers in the right direction of how to solve my problem would be greatly appreciated
