Temperature Monitoring FAQ

What Can I Do To See My CPU Temperature?

It’s unlikely that your operating system contains a default way to monitor the temperature. To get to your CPU temperature manually, you’d have to scour through the BIOS. Instead of this, most opt to simply get a temperature monitoring tool, as there are some excellent tools out there(even if you’re looking for freeware)

What Is A Normal CPU Temperature

During very active use, it’s normal for a PC to reach up to 70-75 degrees Celsius. On the other hand, an idle PC should be at around 45 degrees. A high temperature implies that there’s a lot of background tasks running. Alternatively, you might be having issues with your fan.

Why Am I Not Getting A Temperature Reading?

If your temperature monitoring tool isn’t giving you a reading, the most likely cause is that the tool is incompatible with your CPU’s temperature gauge’s output mechanisms. Looking for a different tool that’s compatible is the most common solution.

Is It Possible For Readings To Be Faulty?

Like with all things, it’s always possible for a reading to be inaccurate. This happens when one of the many factors that go into determining the temperature correctly goes wrong. To find these, you should look for illogical outcomes. An example of this is if your CPU isn’t registering any activity, the fan is working, but the monitor says that you’ve got overheating issues.

Wrapping Up

Having temperature monitoring solutions can alleviate many problems with running large server rooms, office spaces, or even home computers. Avoiding a crash is crucial for day-to-day operations, so having a quality tool that will alert you if something goes wrong.

As always, the most crucial factor is your needs. Our number 5 pick might be your first pick if you’re looking for the specific features it offers. However, always keep your needs in mind, and use lists only as a guideline.
