New Guide - Changing fans in a CyberPower UPS

Just a quick update. I recently wrote a guide on how to replace dead fans in a CyberPower UPS. They use high speed (4000RPM+) fans in the factory, which you just can't easily get.

This guide shows you how to fool the UPS into thinking it has a high speed fan and still operate.

Be careful though, this is messing with mains voltage and reducing airflow - you might burn your house down.
