Pc Monitor PC Monitor displays your computer’s CPU and GPU temperatures and loads, along with system RAM usage, on MeowKit. Keep essential readings in view while you work or play.

​
Before you start

You need a 64-bit Windows 10 or 11 PC, a USB data cable, and HardwareSerialMonitor. Windows 7 SP1 can run the client with .NET Framework 4.8, but it is a legacy system and has not been verified with every hardware configuration. Download and install the v1.4.4 installer. You can also use the MeowKit Windows package. Extract the entire ZIP before opening HardwareSerialMonitor.exe.

​
Connect MeowKit

1

Turn on and connect MeowKit.

Turn on MeowKit normally and connect it to your PC with a USB data cable.
2

​
Read the screen

The top-left panel shows the CPU model, clock speed, temperature, and load. The top-right panel shows total RAM and the percentage in use. The lower panel shows GPU details, including temperature, load, clock speed, VRAM, and available fan readings. The meters update as MeowKit receives data from your PC. -- means the Windows client has not supplied a usable reading for that field. Sensor availability depends on your hardware and the Windows client. Press and hold B to leave PC Monitor.

​
If readings do not appear

Check the USB data cable and the COM port selected in HardwareSerialMonitor. Close any serial monitor using that port. If you reconnect MeowKit, Windows may assign it a different COM port; select the new port in the client. If data stops arriving, MeowKit clears the old readings after five seconds. The display updates again when valid data returns.
