My appliance fans are very noisy

Vectra Cognito appliances achieve high performance throughput in software.  This is achieved by dedicating system CPUs exclusively to packet processing.  These CPUs normally run at 100% utilization and the resulting cooling demand causes the system fans to run at very high speeds.

The high speed operation of system fans do cause an increase in noise for the appliance.  This is normal and should not concern a system administrator.
