@bh6 Hello, apologies for reaching out this way, but would it be possible for you and I to discuss a previous project you did? Specifically this one right here https://electronics.stackexchange.com/questions/555541/12v-4-pin-noctua-nf-a8-on-raspberry-pi-4b

I have some questions about how you got the external power supply working. Please reach out to me at [email protected], thank you in advance!
