Dear Dr Bhattacharya,

thank you very much for your comments. However, it is unclear why you didn't use the built-in contact feature of Hardware Monitor to send your technical support question directly to us? We usually answer such questions within 90 minutes.

A Mac Pro usually doesn't contain any graphics card temperature sensors. It is also technically impossible that you receive a message like "Sensor disconnected" as a reading, because readouts can never contain any text messages. So something must be definitely wrong with your technical description of the problem.

I can only guess you are not displaying readings at all but the display preferences for a second computer. You may have used the remote monitoring feature of the application to monitor a different computer on your network via your Mac Pro. The remote computer is currently offline, but the Mac Pro still keeps your display preferences in case the remote system will go online again later. This would be the correct and normal behavior.

For further questions on Hardware Monitor please contact us directly.
