The 9 Best Laptop and PC Temperature Monitor Apps

Heat causes havoc on computers, particularly laptops. Tight cases and dust accumulation might cause poor air circulation. The heat created within has nowhere to go if there is no circulation.

Ignoring heat issues is the most certain way to ruin a laptop. Did you think it slowed down because it was old? That is somewhat correct, but it is not the whole tale.

Heat may drastically degrade the performance of computer components, with hard drives being particularly vulnerable. Check the internal temperature of your hard disk first if it seems to be dying. Thankfully, monitoring temperatures is as simple as downloading one of these free heat monitor apps.

1. CrystalDiskInfo

Look no farther than CrystalDiskInfo if your main laptop temperature worry is an overheated hard disk. This is a specific software for maintaining HDD and SSD health, and it is so handy that we consider it a must-have diagnostic tool for Windows users.

You’ll have no issue accessing all the information it offers for you, revealing your laptop’s hard disk temperature in a flash, thanks to its straightforward and easy-to-use layout. And, with all of its complex capabilities, it’s useful for power users as well as beginners.

Notable features include:

  • Temperatures for all system HDDs and SSDs are monitored.

HWiNFO is a little diagnostic tool for gathering detailed hardware information and monitoring systems in real time. It’s much simpler to use than it sounds. Furthermore, it is continuously updated—a new version is released every 1-2 months, which is ideal for cutting-edge systems.

Notable features include:

  • System tray icon displaying real-time data.
  • CPU, RAM, HDDs, SSDs, battery, and more reports are available.
  • Remote monitoring of sensor data is possible.
  • Available in 32-bit and 64-bit versions, both installed and portable.
  • For older computers, an MS-DOS version is available.

4. HWMonitor

HWMonitor is one of the most dependable laptop temperature monitoring applications available today. The free version is more than enough for monitoring temperature, but a Pro edition with enhanced capabilities (such as graph production) is available for €20.

Notable features include:

  • Read any voltage, temperature, or fan sensor.
  • Save monitoring data to a log for future reference.
  • Updates the BIOS and drivers.
  • Available in 32-bit and 64-bit versions, both installed and portable.

5. Macs Fan Control

When running Windows on a Mac, things get a little more complicated since Mac hardware has a few unique idiosyncrasies.

The good news is that there is a free program called Macs Fan Control that was created particularly for you. It’s simple to use and highly recommended for monitoring a broad variety of hardware temperatures.

Notable features include:

  • The system tray icon displays the current temperature.
  • Choose which sensor to show in the system tray icon.
  • Set custom minimum and maximum fan RPMs depending on sensor results.
  • Sensors for third-party HDDs and SSDs are supported.
  • Every model is supported, including the iMac, MacBook, Mac Mini, and Mac Pro.

6. SpeedFan

In addition to the risk of hardware damage, excessive system temperatures force your laptop’s fans to work overtime. A hardworking fan lasts longer, but more importantly, fast-spinning fans are noisy. Much louder than you’d expect. It’s one of the reasons we recommend getting a good laptop cooling pad.

The simplest approach to hush loud laptop fans is to use SpeedFan to manually regulate fan revolutions per minute (RPM). SpeedFan also provides temperature monitoring functions, making it a 2-in-1 app—albeit not as powerful as the others listed above.

Unfortunately, Speedfan hasn’t been updated in many years, but it’s still a capable hardware monitoring tool.

Notable features include:

  • System tray icon displaying real-time data.
  • Read any voltage, temperature, or fan sensor.
  • Set custom minimum and maximum fan RPMs depending on sensor results.
  • Sensor temperature measurements should be adjusted and corrected.
  • For troubleshooting, plot values over time.

7. Open Hardware Monitor

Open Hardware Monitor is a free and open-source alternative to HWiNFO and HWMonitor. In truth, Open Hardware Monitor was thought to be a defunct project since it has not been updated since 2016. (which stopped Open Hardware Monitor from working with some of the latest hardware).

However, in early 2020, Open Components Monitor updates started to be released, bringing the laptop temperature monitoring application up to date with the most recent CPUs, GPUs, and other hardware.

Notable features include:

  • Most voltage, temperature, and fan sensors can be read.
  • Save sensor data to a log for future reference.
  • Data is displayed on a distant web server.
  • Because it is portable, no installation is required.

Tips for Reducing Laptop Temperatures

Check your CPU and other hardware temperatures both while your laptop is idle (no programs running) and when it is under stress (with performance-heavy apps running).A high idle temperature may be just as damaging as a high load temperature.
