Upon opening the application, you will see a list of all detected sensors in your system.
View Sensors: Expand the items in the list (CPU, GPU, Motherboard) to see detailed statistics.
Understand the Data: For every component, you can see the Current reading, Min, and Max values.
Monitor Temperatures: Look under your CPU (e.g., Intel Core or AMD Ryzen) and GPU (e.g., NVIDIA or AMD Radeon) sections for “Temperature” or “Package” temperatures.
Monitor Voltages: Look under the motherboard section to see voltage readings for the CPU (Vcore), RAM, and 12V/5V/3.3V rails. 3. Essential Settings and Customization
To make the best use of the tool, you can customize how it runs.
Start Minimized: Go to Options -> Start Minimized to have it open in the background.
System Tray: Select Options -> Minimize to System Tray to keep your taskbar clean.
