If you are a computer user, then a CPU cooler is the common thing you come across every time. There are two types of CPU coolers, i.e. the Liquid Cooler and the Fan cooler. Liquid coolers are used in the high-end Pcs, while Fan coolers are used in the low-end Pcs. The work of the cooler is to keep the processor cooler, so the performance of your pc gets a boost. But often, the CPU cooler stops working for many reasons, and the user is unaware of it. So here is a context focusing on the stoppage of working the CPU cooler. So be with the steps to identify it.

What is a CPU cooler?

A CPU cooler is a coolant that helps your processor, i.e. the chipset of your pc, to cool down. While using the pc, you come across many high-end tasks that use a huge processor unit and heat up. After heating up, there are chances that the components may get damaged and lead to the failure of performance. So to avoid this, the CPU coolers are used. CPU coolers come with a built-in mechanism, i.e. either a fan or liquid that brings down the heat of your processor.

How to tell if the CPU cooler is working or not?

So here are some software and techniques that will help you understand the functioning of your CPU cooler;

Using the NZXT software:

NZXT software is useful software for monitoring your CPU temperature. The reading of CPU temperature above 97 degrees Celsius indicates that either your CPU cooler isn’t working properly or your thermal paste is expired. So here are the steps to download and install the NZXT software on your system.

  • Open your web browser.
  • Then enter “NZXT Download” in the search bar.
  • Now just go to the first result appearing after you enter the search button.
  • Then you will get a free download button.
  • Click on it, and your file will download within a few seconds.
  • Now go to the download location and double-click on the NZXT setup file.
  • Then simply follow the on-screen process to get the software installation steps.
  • Now open the NZXT software.
  • Click on the continue in guest mode button.
  • Then go to settings and then to overlay.
  • Select the size as large and opacity as 50%.
  • Then apply changes.
  • Now open any high-end game or some applications.
  • Click on “Ctrl + O”.
  • So in this way, you can check for the CPU temperature as well as heating.
  • If the readings are above 97, then replace or check for the CPU cooler.

Checking the CPU temperature using the BIOS:

BIOS provides you with all the details of your system. It also provides you with the health of your CPU as well as all the components. So here are the steps to check the CPU temperature;

  • Go to the start button of your windows Pc.
  • Then click on the restart button.
  • Now, as your PC boots up, press the del button or the F2 button frequently.
  • Now the bios of your pc will open up.
  • Use the arrow keys to scroll the options on the bios.
  • Go to the PC health option.
  • Here you will get the CPU temperature along with other CPU health fields.
  • So in this way, you can compare the CPU temperature readings with the normal readings and find out the Cooler problem.

Checking the CPU cooler components physically:

There are many components, such as the CPU cooler Fan, coolant, and Cooler Pads, that prevent the heating up of your processor. Here is how you can check all these components one by one;

CPU cooler pads:

There are thermal pads provided with the CPU cooler that is in place in contact with the processor. Sometimes these pads are faulty, and you need to check whether the pads transmit the heat properly or not. There are also many reasons behind the dysfunction of thermal pads. So, first of all, turn on the cooler and then check for the thermal pads of your CPU cooler.

CPU cooler Fan:

If you are using a Fan cooler, properly working the CPU fans is essential. If your Fan is not set to proper RPM, i.e. revolutions per minute, then the cooling will not take place properly. So CPU Fans must rotate in a particular RPM. There is some inbuilt software for the ASUS and HP laptops that help check the Fan speed. But you can also download some external software to check the Fan speed. Also, you can run the CPU cooler manually and check whether the RPM of the Fan is normal or not.

CPU cooler Coolant:

The liquid cooler contains the coolant. So you need to check the expiry date of the coolant. Generally, the coolant needs to be replaced every 2 to 3 years, depending on your usage. The coolant helps transmit heat from the processor to the cooler. If the coolant expires or consists of any air bubble, then the cooling done by it will not be efficient. So if you come across such a condition, then you can simply replace the coolant or fill up fresh coolant.

Leakage in the liquid cooler:

The liquid cooler consists of tubes made up of fiber or glass material. Sometimes due to manufacturing defects, you may come across that the tubes consist of pores, and the liquid drains through them. So first remove the CPU cover, then check whether the liquid cooler is leaking. If yes, then try to stop the leakage or else change the tube or the component that leaks up.

Checking of the Thermal paste:

As the thermal paste is an important component in transmitting heat between the processor and the cooler sink, checking whether the thermal paste has expired is important.

So in this way, these are all the techniques and software that will help you find out the actual problem existing with your CPU cooler. And also answers to your question, i.e. How to tell if the CPU cooler is Working? (Liquid & Fan).
