How to check laptop cooling fan most accurately

The cooling fan is an important device in the laptop components when ensuring the laptop dissipates heat better to ensure the best performance of the machine. Let's learn how to check the laptop cooling fan most accurately.

The role of the cooling fan

Laptops are different from PCs and desktops in that they are much smaller in size, but their functions and accessories are not much less. Therefore, the cooling fan plays a very important role in helping to ensure that the laptop's temperature is always within the appropriate level so that the machine's performance is maximized.

When operating at high intensity, the machine temperature increases rapidly and affects the working frequency of the components, and can even cause short circuits and damage to some important components. Therefore, a cooling fan will help the laptop operate at its best.

How to check laptop cooling fan

Method 1: Listen to the noise

The simplest and most basic way to check a laptop cooling fan is to listen to the sound coming from the laptop cooling fan. Most types of cooling fans have a standard noise when operating, but when the fan is starting up, if the fan noise is louder than when it is operating stably.

Therefore, it is necessary to determine the noise level that the laptop cooling fan has emitted compared to the standard noise level to determine whether the fan's performance is stable or not.

Note that with some modern laptop products, the cooling fan is turned on and off more flexibly. When the machine is working a lot, requiring more processing power, the machine temperature is hotter than the allowed level, the laptop cooling fan will be activated. Some activities can make the machine heat up quickly such as: creating digital content, editing Photoshop images, videos, playing games, .

The purpose of starting the cooling fan when needed is to save power and focus on working more efficiently.

Method 2: Feel the radiator fan

Feeling the cooling fan is a basic way to check the laptop cooling fan that almost everyone has used. Determine the location of the cooling fan blowing air out of the computer, the cooling vents of the laptop are usually on the left side or the back, bottom of the laptop.

If you can't hear the fan running, you can place a very light piece of paper next to the vent. If the paper flies, the fan is running.

However, most of the current laptop models are designed to be quite thin and light, so the size of the ventilation fan is also very small, and cannot blow away small papers.

Method 3: Check the radiator fan via software

The most popular software used to check laptop cooling fans is SpeedFan. It helps to check the operating status of the laptop, quickly and safely detect possible problems with the cooling fan.

One of the main and most important features of SpeedFan is that it can check the temperature of many hardware components inside a laptop.

The first screen that appears when SpeedFen is activated is the Readings tab selected. This is where metrics such as fan speed, CPU speed , GPU speed, etc. are displayed. If the GPU has multiple cores, the temperature of each core used can be displayed.

In fact, some graphics cards have their own fans, so SpeedFan can check each specific GPU. From the temperature table provided, users can evaluate the performance required for the fan and have appropriate solutions for their laptop.

When the laptop cooling fan is running but the laptop still generates a lot of heat, it needs to be fixed immediately to ensure the best performance of the machine. Try cleaning the laptop cooling fan immediately to improve the situation.

Above is basic information about the simplest, most accurate and effective ways to check laptop cooling fans . Hopefully, the article has provided readers with basic knowledge so that their laptops can operate at their best.
