ガイド/Best temperature monitors for Mac
The 6 best temperature monitors for Mac
結論
Vitals is the best temperature monitor for Mac if you want the temperature and the reason for it. It reads the CPU, GPU, SSD and battery sensors, puts the CPU, the GPU or the hottest sensor in the menu bar, names the apps heating the Mac with Quit beside each, tells you when the Mac stays above a temperature you choose, and can set each fan's speed. TG Pro is the specialist: fan rules by temperature, email alerts and CSV logs. Stats is the best free one, and Macs Fan Control is the free pick for fans.
How to check a Mac's temperature without an app
- 01 Open Terminal: press ⌘Space, type Terminal and press Return.
- 02 On a Mac with Apple silicon, run
sudo powermetrics --samplers thermal -n 1. It reports the thermal pressure, such as Nominal or Heavy, not a temperature in degrees. - 03 On an Intel Mac, run
sudo powermetrics --samplers smc -n 1. It prints the CPU temperature and the fan speed. - 04 To find what is producing the heat, open Activity Monitor, click CPU and sort by % CPU.
macOS has no temperature readout in Activity Monitor or System Settings, which is why these apps exist. Apple's own advice is to use a Mac laptop where the room is between 10° and 35° C (50° to 95° F).
A Mac measures its own temperature in a dozen places and shows you none of them. A temperature monitor reads those sensors: the CPU cores, the GPU, the SSD, the battery, the air moving through the case. The good ones also put a reading in the menu bar, warn you at a limit you set, and let you run the fans harder. Only one says which app is behind the heat. The apps below are ranked on all of it, and each is labeled with the job it does best.

Most temperature monitors stop at the number. Vitals goes on to the cause. Its Temperature & Fans panel shows the CPU, the GPU and the hottest sensor, then every sensor it reads: efficiency and performance cores, GPU, SSD, battery, Wi-Fi and airflow. When the Mac is hot or the fans are working, a card names the apps responsible, by the power each is drawing, with Quit beside each. The menu bar can show the CPU, the GPU or the hottest sensor, in Celsius or Fahrenheit. It notifies you when the Mac stays hotter than a limit you set, from 70 to 105 °C, and keeps the average and peak temperature for 30 days, or up to a year. Each fan can stay on automatic or run at a speed you set, and every fan goes back to automatic when Vitals quits. It runs on Apple silicon and Intel Macs. Reading temperatures needs no extra permission; setting a fan needs Full System Metrics turned on.

TG Pro is the specialist. It reads CPU temperatures, including single cores on Apple silicon, the GPU, internal and external drives, the battery, and more, and keeps the highest reading for each sensor. Its Auto Boost rules raise the fans when a sensor you choose passes a temperature you choose, and fans can also be set by hand. It sends notifications and email alerts at your own limits, logs temperatures and fan speeds to CSV, and checks the hardware: fans, sensors, battery health and the last shutdown. It runs on Intel and Apple silicon, macOS 10.14 to 27. Version 2.104.
良い点
- Fan rules by temperature, for any sensor
- Notifications and email alerts at your own limits
- CSV logs of temperatures and fan speeds
- Hardware checks for fans, sensors and battery

When you do not need a temperature monitor
A Mac looks after its own temperature. It speeds up the fans, and if that is not enough it slows the chip down, long before anything is damaged. If your Mac is quiet and quick, you do not need to watch a number, and a high reading during a video export or a game is the chip doing its job.
A monitor earns its place when the Mac is hot or loud and you do not know why, or when you want to hear about it before it slows down. Start with why a Mac's fans get loud, and see how to control fan speed on a Mac before you set a fan by hand.

価格と機能はすべて、2026年10月12日にメーカー自身のWebサイトで確認したものです。価格ページ、製品ページ、App Storeのページ、オープンソースのツールについてはGitHubのREADMEとリリース履歴を見ています。メーカーがアプリの機能について明記していない場合は、このページでも“ある”とも“ない”とも書いていません。価格は変わることがあるので、購入前にメーカーのWebサイトで確認してください。
iStat Menus and Stats were checked on September 22, 2026. Vitals is first because it is the only one here that names the app behind the heat, which is what a hot Mac needs fixed, and it covers the rest: sensors, the menu bar, an alert at your own limit, and fan speed. TG Pro is second because nothing here does more with fans and alerts, and if fan rules by temperature are what you want, it is the better pick; the entry says so. Every other app is ranked for how well it does the whole job. If something here is out of date, email us and we will fix it.
よくある質問
How do I check my Mac's CPU temperature?
macOS does not show it. On an Intel Mac, sudo powermetrics --samplers smc -n 1 in Terminal prints it. On Apple silicon, Terminal reports only the thermal pressure, so you need an app: Vitals, TG Pro, iStat Menus and Stats all show CPU temperature.
What is the best free temperature monitor for Mac?
Stats. It is free and open source and puts temperatures in the menu bar. Macs Fan Control is free and adds fan control, and mactop is free in the terminal on Apple silicon.
Is there an app that shows which app is heating my Mac?
Vitals. When the Mac is hot or the fans are working, it names the apps responsible, ranked by the power each is drawing, with Quit beside each. On a Mac without fans the same card is called Heating This Mac.
Can I see my Mac's temperature in the menu bar?
Yes. Vitals shows the CPU, the GPU or the hottest sensor. TG Pro, iStat Menus, Stats and Macs Fan Control put temperatures in the menu bar too.
What temperature is too hot for a Mac?
Apple does not publish a limit for the chip. A Mac protects itself: it runs the fans faster, then slows the chip down. What matters is a Mac that stays hot with nothing heavy running, which means an app is busy when it should not be. Vitals' own alert starts at 90 °C held for 3 minutes, and you can change both.
Does a MacBook Air have temperature sensors?
Yes. A Mac without fans still measures its temperature, and Vitals and TG Pro both read it. There are no fans to control, so the Mac cools itself by slowing down.
