Preface This post describes: My success at cooling fan lubrication on an NVIDIA GeForce GTS240 PC display adapter to silence it when it became noisy.
Introduction This post is about the RING Automotive Air Compressor RAC900 which is an excellent pump for inflating anything with a Schrader valve, (e.g. car tyres, bicycle tyres, etc.) or balls, airbeds, etc. (3 Inflation Adapters are supplied). It has to be powered by a 12 volt (30 amp peak) supply such as a car battery (not provided).
