Why Do My GPU Fans Run for a Few Seconds Then Stop? (what should I do? Explained)

Usually, when you turn on your computer, it is perfectly normal. Graphics card fans will turn around and then stop after a few seconds.

It is a “security” when the PC gets electricity so that the ventilators can avoid overheating and regulate after a few seconds. It takes long enough for the temperature sensor to identify no particular problem.

So don’t worry if you’re in this situation; most graphics cards do when you turn on the computer. 

This article will focus on spinning and stopping graphics card fans. It is a very common phenomenon that can upset some people.

We’ll explain why your PC’s fans turn on and off, and then we’ll show you how to control their functioning.

Why Do Graphics card fans run for a few seconds and then stop?

An attitude that may seem unusual, especially if you don’t have any special computer skills. Rest assured, you are not alone in seeing this behavior, and many people ask the same question.

If the graphics card’s fans start spinning, the card is warming up. Their job is to create airflow to cool the GPU and allow it to function properly.

If a board gets too hot, it will shut down, a phenomenon called “thermal throttling,” Over time, it can damage components.

GPU Fans that turn On when I launch a Game And then stop

It usually happens when you launch the game if it’s in a game that drives your graphics card fans away. There is almost the same procedure involved.

When you start a video game, your card is pressed for a while, then when you are in the menu, its temperature stabilizes, and the fans are under less pressure.

However, a crash can occur when the graphics card fans start running, and the screen goes black.

Solution for Your graphics card fan isn’t working.

Suppose you ever get the impression that your graphics card’s fans aren’t moving enough, and they only turn on temporarily.

In that case, you’ll have to check all the important information to ensure your GPU is working properly. Everything must work properly. Otherwise, you will feel the disadvantages or performance of FPS in using it for your favorite software or video games, here are some solutions: 

1. Check the temperature of your graphics card.
2. Manage your graphics card fan speed

   

1. Check the temperature of your graphics card.

The graphics card temperature mustn’t rise too much, assuming that the maximum temperatures depending on the states and cards are: 

• Graphics card useless: on average, between 45 and 55 degrees
• The fixed PC graphics card in games or over-use: Between 70 and 95 degrees; above 95 degrees, you must follow the ventilation as your card gets hotter.
• The laptop graphics card in use: between 80 and 100 degrees

So checking this data, nothing could be easier; download MSI Afterburner, the free software popular for gamers and cryptocurrency miners. It lets you control your graphics card’s fan, temperature, and power.

You will be able to see the temperature of your graphics card during T and the temperature curve at the last minute.

2. Manage your graphics card fan speed

Finally, thanks to the same software, MSI After Burner, you can control the power of your graphics card fan.

That way, you’ll be able to adjust the fan’s operation percentage according to the latter’s temperature.

If you want them to operate hard at low temperatures, you can, and the inverse is true.

The first rectangle in the upper right corner displays the GPU temperature curve at T; the second rectangle shows the fan speed % at T; and the third rectangle displays the temperature curve at T., the temperature curve of your graphics card.

To adjust your fan curves and thus reduce their noise and power, you’ll need to go to Settings:

Then in the settings window, you can edit the fan curves for:

• Step 1: Go to the “Fan” section
• Step 2: Check the “Enable Auto Fan Control User Mode” box.
• Step 3: Set the fan curve to “Custom”
• Step 4: You can edit and add points on the curve by holding and dragging the mouse. That way, you can turn your fans on more slowly or when the temperature rises. Keep in mind that keeping the operating temperature between 70 and 95 degrees is advisable.

Final Thought

There is a part of the motherboard called the BIOS. BIOS is responsible for booting the system. When you power the PC, the BIOS takes a while to launch, and during that time, GPU fans get no commands to keep up with their speed so they can rotate as fast as they can.

As soon as the BIOS starts, the fan speed returns to normal. The motherboard manufacturers considered this issue a concern, but then they realized that it would not be a problem and could benefit. Fast startup fans can help remove dust or sediment from the GPU.
