On Windows, use MSI Afterburner or GPU-Z to monitor GPU temperature, with Task Manager offering limited support on newer systems. 2. On macOS, use iStat Menus or Macs Fan Control for temperature readings, though Apple Silicon Macs may not provide separate GPU temperatures. 3. On Linux, use nvidia-smi for NVIDIA GPUs, lm-sensors or radeontop for AMD, depending on hardware. 4. Ensure drivers are updated, maintain proper cooling, and consider temperatures above 90°C under load as potentially problematic due to cooling or airflow issues.

Checking your GPU temperature is important for monitoring system health, especially during gaming or heavy workloads. Here’s how to do it on Windows, macOS, and Linux.

Using Software Tools on Windows

Most users rely on third-party software to monitor GPU temperature on Windows. Here are the most common and reliable options:

• MSI Afterburner
  This is one of the most popular tools. It overlays real-time stats (including temperature, usage, and fan speed) directly on your screen while gaming.
  Steps:

  
  • Download and install MSI Afterburner.
  • Launch the program and enable the on-screen display (OSD) in settings.
  • Add temperature monitoring via the monitoring tab.
  • Use a hotkey (default is Ctrl O) to show/hide the overlay.

• GPU-Z
  A lightweight utility that provides detailed GPU information.

  • Download and run GPU-Z (no installation needed).
  • Look at the "Sensors" tab to see real-time temperature, clock speeds, and fan speed.
  • It doesn’t run in the background by default, so open it when you need to check stats.

• Task Manager (Windows 11 and 10, 20H2 and later)
  Windows now includes basic GPU monitoring.

  
  • Press Ctrl Shift Esc to open Task Manager.
  • Go to the “Performance” tab.
  • Click on “GPU” — you’ll see usage, dedicated memory, and sometimes temperature (limited to certain drivers and GPUs, especially NVIDIA and AMD recent models).

On macOS

Apple doesn’t provide built-in GPU temperature monitoring, and access is limited due to system architecture. However, you can use:

• iStat Menus or Macs Fan Control
  These third-party apps can read GPU temperature on Intel-based Macs (Apple Silicon support is limited and may not show discrete GPU temps).
  • Install one of these apps.
  • Check the menu bar or sensor panel for GPU temperature readings.

Note: On M1/M2 Macs, GPU is integrated into the SoC, and temperature readings may not be separated from the overall chip temperature.

On Linux

Linux users have several command-line and GUI options:

• nvidia-smi (for NVIDIA GPUs)
  Open a terminal and type:

  nvidia-smi

  This shows GPU utilization, memory, and temperature. For continuous monitoring:

  watch -n 2 nvidia-smi

• lm-sensors (for AMD and some NVIDIA)
  Install and configure sensors:

  sudo apt install lm-sensors
  sudo sensors-detect
  sensors

  This may show GPU temperature if supported by your hardware and drivers.

• radeontop (for AMD GPUs)
  Useful for monitoring AMD Radeon cards:

  sudo apt install radeontop
  radeontop

General Tips

• Make sure your GPU drivers are up to date — older drivers may not report temperature correctly.
• Normal GPU temps under load are usually between 60–85°C. Above 90°C may indicate cooling issues.
• Dust buildup or poor airflow can cause high temperatures — clean your system regularly.

Basically, use GPU-Z or MSI Afterburner on Windows, nvidia-smi on Linux, and iStat Menus on macOS. It’s not complicated, but the right tool depends on your OS and hardware.
