GMKTec K6 120mm fan adapter + external (RP-)SMA antennas

Hello,

This part allows you to install a 120mm fan on the GMKTec K6 and two SMA or RP-SMA antennas for better WiFi and Bluetooth connectivity (the antennas supplied with the device are very poor quality, especially for Bluetooth).

You will need:

• 1 x 120mm PWM fan
• 4 x 10mm M3 screws
• 4 x standard 120mm fan screws
• 1 x 12V step up module
• 2 x RP-SMA (or SMA) to IPEX4/MHF4 antennas
• soldering equipment

If you reverse the blue and yellow wires as I did on my first attempt, the fan will run at 100% all the time and be very noisy, but if you make the connection correctly, the motherboard will be able to adjust the rotation speed according to the heat/use of the PC.

If you are using the same fan as me, an Arctic P12 PWM PST, there is some extremely well-done documentation online to help you identify and solder the right wires together: https://support.arctic.de/fr/p12-pwm. Click on “Mounting the fan” and then “Mounting in a DIY project.”

To complete this mod, I also printed this fan filter: https://makerworld.com/fr/models/967259-80-92-120-140mm-fan-dust-filter as well as these feet: https://www.printables.com/model/1309654-gmktec-nucbox-m5-plus-k6-height-extension-stand.
