How to Monitor Fan Speed on macOS 13 Ventura

Monitoring your fan speeds on macOS 13 Ventura is essential for managing thermal performance, identifying cooling issues, and preventing hardware throttling during resource-heavy tasks. Because Apple does not include a native utility in macOS to display real-time fan revolutions per minute (RPM), you must rely on trusted third-party software. This guide covers the best third-party utilities available for macOS 13 and outlines the straightforward steps to install and use them to check your fan speeds.

1. Macs Fan Control

Macs Fan Control is the most widely used utility for monitoring and adjusting fan speeds on both Intel and Apple Silicon Macs running macOS 13.

  1. Download Macs Fan Control from the developer's official website.
  2. Open the downloaded DMG file and drag the app into your Applications folder.
  3. Launch the app. If prompted by macOS 13 Ventura security, go to System Settings > Privacy & Security to allow the application to open.
  4. Once open, the main window displays a list of your Mac’s fans, their current RPM, minimum RPM, and maximum RPM alongside temperature sensor readings.
  5. To monitor speeds continuously, click Preferences within the app, select the Menubar display tab, and choose your fan to display its real-time speed in the menu bar.

2. Stats (Open-Source Option)

Stats is a lightweight, open-source system monitor that lives entirely in the macOS menu bar, providing detailed information on CPU, GPU, memory, disks, and fans.

  1. Download the latest release of Stats from GitHub or install it via Homebrew using the terminal command: brew install --cask stats.
  2. Launch Stats from your Applications folder.
  3. Open the Stats settings by clicking its menu bar icon and selecting the gear icon.
  4. Navigate to the Sensors tab and enable the module.
  5. Under the Fans section, toggle on the option to display current fan speeds directly in your menu bar.

3. TG Pro

TG Pro is a premium, feature-rich utility designed specifically for Mac temperature and fan diagnostics, fully optimized for macOS 13 and Apple Silicon architectures.

  1. Download and install TG Pro.
  2. When prompted, install the required helper tool to grant the application permission to interface with your Mac's internal hardware controllers.
  3. View the Fans section in the main dashboard to check current speeds against target speeds.
  4. Enable the menu bar icon to keep an eye on hardware temperatures and fan RPMs at a glance without keeping the main application window open.

Understanding Your Fan Speed Readings

  • Idle Speeds: On most Mac laptops and desktops, baseline idle fan speeds range between 1,200 and 2,000 RPM, depending on the specific model. Apple Silicon MacBook Air models do not have internal fans, meaning third-party utilities will show no fan hardware present.
  • Maximum Speeds: Under sustained CPU or GPU workloads (such as rendering video or 3D modeling), fan speeds can ramp up between 5,000 and 6,500 RPM.
  • Sensor Communication: If an application reports 0 RPM on a device equipped with a fan while the Mac is hot, restart your Mac and ensure that the third-party app has been granted necessary permissions under macOS Ventura's Privacy & Security settings.
