I disassembled an AMD CPU Wraith Cooler, meaning, I took the fan off of the heatsink, because I want to attach the fan on top of a Raspberry Pi that I'm using as a router. The Pi runs quite hot because it transmits several hundred megabytes per second, non stop, and I want to give it some cooling. (It already has its own heatsinks on its various chips inside the chassi and I don't want to use the little shitty Okdo fan, because it's loud.)
Is there any smart solution to how I could power this 4-pin fan? It needs 12V DC.
This is the Pi with its chassi.
And I'm considering something barbaric like this.
~~Are there perhaps conveniently positioned GPIO pins on the Pi that the 4-pin connector could just slide on to and just work?~~ Never mind this. The Pi 4 that I'm using can only output 5V:
Or would I need to cut off the 4-pin connector to expose the individual wires and attach them to a 12V DC adapter?
Or any other genuis solutions? :)
If you decide you wanna go the easy route there are quiet 5V fans out there

Thanks! That lead me to discover this: https://www.noctua.at/en/products/nv-ps1/specifications Which I guess would have the fan blast away at full speed, but maybe I could force a potentiometer in between somewhere somehow...?
Or, I just go the easy way, as you said. I just hate to know that the Wraith is sitting in my closet, unused... XD
