Since the update/overhaul a couple versions back with Precision XOC, there was a significant change made to how the hardware monitor works and the settings you can use.
 
The feature that was dropped during that update, would be nice to have back. That feature is the ability to adjust the chart of each item that is being monitored.
 
For instance, at no point will my GPU ever hit 0*c, nor will it ever hit 100*c. My GPU also sits from 600mhz to 2075 mhz. But that chart starts at 0mhz and goes to 2500mhz, two frequencies that my GPU will never see. Why does the monitor have those? Its useless space on the chart. Prior to the major change you could set the min/max values for each item being monitored so the chart's top and bottom were useful.
 
I really hope to see more work put into the HWM.
