Do GPU Fans Always Spin – Causes And Fixed – 2024

Think about playing a fun game, and then it becomes very quiet. The noisy fans stop. This happens because sometimes your computer doesn’t need the fans to spin fast.

No, GPU fans do not always spin. They typically only spin when the graphics processing unit (GPU) reaches a certain temperature threshold to maintain optimal cooling.

In this article, we’ll find out why GPU fans sometimes don’t make noise. We’ll look into how graphics cards stay cool and share some cool secrets.

GPU Fans Not Working – Causes And Solutions:

If your GPU fans are not working, several potential causes could be at play:


1. Fan Failure: The most obvious reason is that the fans themselves have malfunctioned or failed. Over time, dust buildup or wear and tear can cause the fans to stop working properly.

2. Dust Accumulation: Dust can accumulate inside your GPU, obstructing the fan blades and preventing them from spinning efficiently. This can lead to overheating and eventually cause the fans to stop working altogether.

3. Disconnected Or Loose Cables: Sometimes, the cables connecting the fans to the GPU or the motherboard can become loose or disconnected, leading to the fans not receiving power or control signals.

4. Software Settings: In some cases, software settings or configurations may prevent the GPU fans from spinning. For instance, if the fan curve is set too low or if there’s a software glitch preventing fan control, the fans may not activate when needed.

5. Driver Issues: Outdated or corrupted graphics card drivers can sometimes cause issues with fan operation. Updating to the latest drivers or reinstalling the existing ones may resolve the problem.

6. Hardware Damage: Physical damage to the GPU, such as bent fan blades or a broken fan motor, can also cause the fans to stop working.

7. Overheating: If the GPU is overheating, it may shut down the fans as a safety measure to prevent further damage. Overheating can be caused by inadequate airflow in the case, a malfunctioning heatsink, or excessive overclocking.

8. BIOS Settings: In rare cases, BIOS settings related to fan control may cause the fans to stop working. Checking and adjusting these settings in the BIOS can potentially resolve the issue.


1. Check Connections: Ensure that the GPU fan power connector is properly connected to the GPU and that there are no loose connections.

2. Dust And Debris: Dust and debris can accumulate on the GPU fan blades, causing them to stop working. Use compressed air or a soft brush to clean the fan blades and remove any obstructions.

3. Software Settings: Sometimes, GPU fan settings in software like MSI Afterburner or your GPU manufacturer’s control panel may be set incorrectly. Check the fan settings in these programs and ensure they are configured to spin the fans when necessary.

4. Driver Updates: Make sure your GPU drivers are up-to-date. Outdated drivers can sometimes cause issues with fan control.

5. BIOS Update: Check if there are any BIOS updates available for your motherboard or GPU. Sometimes, BIOS updates can fix compatibility issues or bugs related to fan control.

6. Fan Failure: If none of the above solutions work, it’s possible that the GPU fan itself has failed and needs to be replaced. Contact the manufacturer for warranty support or consider replacing the fan if your warranty has expired.

7. Temperature Monitoring: Use temperature monitoring software to check the GPU temperature. If the temperature is within safe limits even without the fans running, it may not be an immediate issue. However, it’s still recommended to have the fans operational for better cooling efficiency.

8. Professional Assistance: If you’re not comfortable performing hardware troubleshooting yourself, consider taking your computer to a professional technician who can diagnose and repair the issue.

Are GPU Fans Supposed To Spin Constantly?

GPU fans are not supposed to spin constantly under normal circumstances. They typically spin up when the graphics card is under heavy load to cool it down. During idle or low-demand tasks, the fans should stop spinning or run at a lower speed to conserve energy and reduce noise.

When Do GPU Fans Start Spinning?

GPU fans start spinning when the temperature of the graphics processing unit (GPU) rises to a certain threshold, typically set by the manufacturer. This occurs during periods of heavy load or when the GPU is under stress to help maintain safe operating temperatures.

What Might Cause The GPU Fans To Always Spin?

Several factors might cause GPU fans to always spin:

1. High Temperatures: If the GPU consistently runs hot due to poor airflow, dust accumulation, or inadequate cooling, the fans may spin constantly to dissipate heat.

2. Software Settings: Incorrect fan settings in the graphics card’s control panel or driver software may cause the fans to run continuously.

3. Hardware Issues: Faulty temperature sensors or a malfunctioning fan controller can also lead to continuous fan operation.

4. Heavy Workloads: Intensive tasks such as gaming or video rendering may keep the GPU under constant load, causing the fans to spin continuously to maintain optimal temperatures.

5. Incorrect Fan Curve: The fan curve settings may not be optimized, causing the fans to spin more aggressively than necessary even under moderate loads.

How Can You Control The Fan’s Spinning Speed?

To control a fan’s spinning speed, you can use a device called a fan controller. It adjusts the power supplied to the fan, which changes its speed. Fan controllers often come with knobs or buttons to easily adjust the speed according to preference.

GPU Fan Will NOT Stop Spinning At Idle!

If the GPU fan does not stop spinning at idle, it could be due to settings or issues with the GPU drivers. Check the graphics card settings and update the drivers to ensure proper functionality. If the problem persists, consult manufacturer support or seek technical assistance.

Is GPU Fan Supposed To Spin Always?

No, the GPU fan is not supposed to spin always. It typically adjusts its speed based on the GPU’s temperature. At idle or low usage, the fan may stop or spin at a very low speed to conserve energy and reduce noise.
