  1. Hi folks! Some problems later I just build my ethereum-node using the FriendlyARM NanoPC T4 (Reddit project Ethereum on NanoPC T4). Using it indoor the temperature climbs to 80° celsius with the passive cpu-heatspreader. So I decided to install a fan and found the specs for the 'Cooling Fan interface'. The connector is named BM03B-GHS-TBT. Where can I buy a fan (40x40mm)? I only find fans with 3-pole-molex-adapter. All I know is the name of the male connector (in german): "JST Buchsengehäuse-Kabel GH Polzahl Gesamt 3 Rastermaß: 1.25 mm GHR-03V-S".

    NanoPC T4 - Fan-connector

    This is my setup. big.LITTLE load %cpu %sys %usr %nice %io %irq Temp 600/1512MHz 1.40 17% 5% 7% 0% 4% 0% 31.1°C 1992/1512MHz 1.37 18% 4% 8% 0% 5% 0% 31.7°C 1992/1512MHz 1.39 21% 5% 10% 0% 5% 0% 31.7°C Attached the fan direct to a power supply.

    Today I received an answer from techsupport@friendlyarm.com:

    Meanwhile I gave up building a connector. How did you succeed building a connector? Do you have a crimp-tool? The parts are so small (and my fingers so clumsy). Just sent a mail to friendlyarm. Maybe a preconfigured fan or adapter exists. Otherwise I will apply a separate power supply only for the fan. Ugly and sad solution.

    @suka Postet in another subchannel:
  6. Hello ! Same problem, another forum: https://forum.armbian.com/topic/9105-nanopc-t4-fan-connector Meanwhile I received the parts to build the connector/cable: On board: JST BM03B-GHS-TBT plug-housing: JST GHR-03V-S plug-contacts: JST MINI-SSHL-002T-P0.2 Soldering? Just forget it. The parts are so small. I just ordered a preconfigured cable via eBay. But the main problem seems to be that the fan is runnig at highest speed, ignoring the PWM signal.

    Thank you! I found the parts and I'll report how it worked out.
