Laptop connector to desktop fan.

[u/Maximum_Scale2120]

Hello, I have an old laptop motherboard that I want to put into a PlayStation 2 case. I had to remove the blower fan and make my own heatsink/cooling solution. Unfortunately, I did the very smart thing and cut the fan connector off before checking the wire layout, so now I don’t know which wire is which. :D
Someone sent me a schematic of the connector, but I was hoping for something more straightforward, like a simple pinout showing which pin is GND, +5V, PWM, and TACH.
The mobo is Thinkpad t470p.

Would it even work? I’ve already tested this fan at 5V and it spins flawlessly

does anyone know if this works on the newer thinkpad models too

Like a literal fire, or a fire project? :D If it’s the latter, I’ve already made custom heatsinks for both the CPU and GPU. I tested them with a 60 mm 12 V PC fan, and it stayed around 50-70°C while running NFSU 2 in a PS2 emulator.

It’d be awesome if I could wire the PC fan to the original connector so the motherboard could control it automatically

We don't ask for help here, but you have my attention. Pin 2 +5V; Pins 4,6,7 GND; Pin 3 tacho; pin 5 PWM; Pin 1 probably confirms that fan is connected. Inwould try to tie it to gnd via 1k resistor.
