Subject:	ASI/TRACEGAS/M1 - Exterior inlet fan box failed
Affected Datastreams:	asiaosnoxM1.01
Description	The exterior fan on inlet box failed. Initial concerns were for converter efficiency, but efficiency has stayed constant. The temperature of the box has been monitored (and recorded). Data should be considered ok.
