Ubiquiti UDM PRO UniFi Dream Machine 4-Pin Fan Adapter

Swap the fan in your Unifi Dream Machine Pro for a standard PWM connector fan. This enables you to replace it with a quieter fan, like a Noctua, which uses a standard 4-pin header. Note that this adapter is a direct replacement for the BFB0712VHD-SM fan from Delta Electronics. Ensure this is the fan you're replacing. The header is a small 4-pin connector, measuring approximately 6.8mm. Carefully check your dimensions to ensure it fits.
