Why Your CPU Is Overheating For No Reason? Here’s How To Fix It

Have you ever thought about why your CPU is overheating for no reason? At billions of cycles per second, the CPU computes multiple complicated algorithms. It is okay to produce some heat when functioning at such high speeds.

CPU temperatures of 50-60 degrees Celsius during regular operation and 80-90 degrees Celsius while heavy activity are relatively frequent. However, if the CPU temperature surpasses this level, it is overheating. Unless your CPU is old or overclocked, overheating is generally caused by poor heat dissipation.

Whatever the cause, we’ll teach you how to properly care for your CPU and keep it from overheating.

Causes of an Overheating CPU

When a CPU overheats, it begins thermal throttling, which reduces performance. But what causes the CPU temperature to exceed its limit? Let’s take a look at some of the causes.

  • CPU fan failure
  • Dust accumulation, Inadequate air circulation
  • Thermal paste depleted
  • Reduced fan speed
  • Processor Overclocking
  • Malware infection is caused by heavy programs running in the background.

Why is your CPU overheating For No Reason?

First, ensure that your BIOS or temperature monitoring program displays the right reading. You can use applications such as HWMonitor, Open Hardware Monitor, and others to monitor the temperature. Check to see whether any of these indicate that your CPU is overheating.

If that’s the case, let’s get started on the fixes straight immediately.

Find Processor-Hogging Programs

Most of the time, the CPU is built to manage heavy loads. However, certain applications require a substantial amount of computing power. The CPU becomes extremely hot when such applications run in the background or forefront indefinitely.

You can discover and terminate such apps using Task Manager.

  • To launch Task Manager, press Ctrl + Shift + Esc.
  • Look for apps and background processes that consume a lot of CPU power in the Processes menu.
  • Select the software and then click Finish task.
  • Apply this to all similar applications and procedures. However, be certain that no system processes are terminated.

Sometimes apps operate in the background, silently utilizing the CPU. You can disable background programs in this instance.

  • To open Settings, press Windows + ‘I’.
  • Inside, you’ll find Apps and Apps & Features.
  • Select Advanced options by clicking the three dots at the right end of an application. This functionality may not be available in all apps.
  • Locate the Background applications permissions setting.
  • Set the Allow this software to operate in the background option to Never.

Look for malware

Not all CPU-intensive apps are malicious. Malware may consume your CPU without mercy if your system is infected. As a result, the CPU load increases and it heats up beyond its maximum.

You should use the Windows Defender utility to do a full virus scan on your PC. A third-party antivirus might be used, but it will cost more processing power. Let’s use Defender to do a virus scan.

  • To launch Windows Security, press Windows + ‘R’ and type ms-settings:windowsdefender.
  • Go to Scan settings after selecting Virus and Threat Protection.
  • Scan now after selecting Full scan.

It may take some time to finish the scan and eradicate the virus. Check to see whether the CPU temperature drops following the malware scan.

Use a Dedicated Graphics Unit

When you run graphics-intensive software or a demanding application, it consumes a significant amount of computing power. The CPU will be taxed much more if you use such programs with integrated graphics. To render pictures, the integrated graphics unit uses the CPU’s processing power.

If you often use heavy programs and play high-end games, you should consider adding a dedicated GPU to your machine. The dedicated GPU is outfitted with its own CPU, memory, and cooling system.

A GPU relieves the CPU even more strain if the Hardware Acceleration function is enabled. This functionality offloads some of the processor’s workload and runs it on other system resources such as the GPU.

Let’s have a look at how to enable Hardware acceleration on your machine.

  • To open Settings, press Windows + ‘I’.
  • Scroll down to locate Graphics options by clicking on Display.
  • At the top, choose Default graphics settings.
  • Change the toggle bar to On to enable Hardware-accelerated GPU Scheduling.

You should notice a considerable reduction in CPU temperature.

Reduce Maximum Processor State

Windows allows you to modify your power plan and customize your system’s power use parameters. You can adopt a balanced power plan or power-saving settings if your laptop’s CPU is overheating. When compared to the High-performance level, this gives a more balanced performance and power utilization.

You can also reduce your Maximum processor state. If your processor is growing older and can’t handle greater loads, lowering the CPU utilization % can assist.

Let’s look at how you may configure these settings on your PC.

  • To launch Power Options, press Windows + ‘R’ and type powercfg.cpl.
  • Choose between the Balanced and Power Saver plans.
  • On the selected plan, click Change Plan Settings.
  • Change the advanced power settings.
  • Alter the advanced power settings
  • Look for processor power management.
  • Set the processor’s maximum state to 60-70%. It depends on how much performance loss you will accept in exchange for reduced CPU temperature.

Stop overclocking

Most of us overclock our CPUs to maximize performance. It also performs a fantastic job. However, overclocking might cause the CPU to throttle to maintain its integrity.

Overclocking your CPU might be a key cause of its excessive temperature. As a result, you should return the overclocked settings to their default defaults. Let’s see what you’re capable of.

  • After the machine boots, hit the appropriate key repeatedly to enter the BIOS page.
  • Press F9 or the corresponding button to load the default settings.
  • Save your changes and restart your computer.

If you utilized software to overclock your CPU, you may simply remove the application.

  • To launch Add or Remove Programs, press Windows + ‘R’ and type appwiz.cpl.
  • Choose the software and then click Uninstall.

Your CPU should now work at regular clock speed and at normal temperature. Aside from overclocking,

If you are involved in bitcoin mining and utilize other demanding apps, they will take significant computing power. So, you can remove such apps to observe whether the CPU temperature changes.
