Re: 5V 4-pin Noctua A4X10 on Raspberry Pi

I'm trying to learn so please don't bite my head off even if I am being extremely stoopid! I have a similar fan. I see people using a 2 pin fan constantly.

Only running SSH and pihole.

No HDMI out, no wifi on and no Bluetooth on.

Has been running at this clock speed since it's been on.

Not sure why?
