Temperatures Setup page
To show disk temperatures, you must run CrystalDiskInfo in the background. You can download CrystalDiskInfo. But it is not enough. You must set up CrystalDiskInfo properly. First go to Function -> Advanced Feature and check Gadget Support.
Choose refresh time. Go to Function -> Auto Refresh and select desired time to refresh. If you select “Disable” temperatures will not be refreshed.
When you add a new disk, you must press the F6 button for quick rescan. Drives Monitor shows this disk immediately, but CrystalDiskInfo no.
