Issue Details

The fan speed for my PXI/PXIe chassis can be set to either automatic or high. Is there an indication of when high should be used?


We recommend selecting the high speed option as it offers maximum cooling performance. While with the auto setting the fan speed is determined by the intake air temperature and hence offers a quieter operation. 
If the power usage and volume of the noise (from the fans) is not a concern then we recommend using the high setting. 

Additional Information

It is also important to note that the specifications also assume that you have selected the high fan speed option.
