GPU Fans Stop Spinning: Fixing Common Causes

GPU Fans Stop Spinning

Has your computer suddenly started sounding like a jet engine during even simple tasks, or is stuttering or crashing more frequently during gameplay? If that is the case, your graphics card (GPU) could be overheating.

Fans are an essential component to keeping your GPU cool, so if GPU fans stop spinning it could indicate an issue.

But don’t panic just yet; solutions exist! Before giving in and going straight for repairs (or worse yet a new graphics card), there may be a few things you can try yourself to bring the fans back online.

This guide provides simple yet straightforward troubleshooting steps you can follow to identify and potentially correct non-spinning GPU fan issues without resorting to costly tools or technical expertise.

From dust accumulation issues to software solutions and clear explanations of their operation – everything is covered here for you in an easily understood fashion.

GPU Fans Stop Spinning – Why?

There could be several reasons why your GPU fans have stopped spinning. Some of the more common issues faced by users include:

  • Feature, Not a Bug
  • Fan Curves
  • Power Supply
  • Obstruction
  • Software or Driver-Related Bugs
  • Faulty GPU Fan

How To Fix?

Follow these fixes exactly as directed if you want your GPU fans to spin at full speed once again.

1. It Might Not Be A Bug But A Feature

Don’t panic if your GPU fans aren’t whirring away all the time! Just like turning off the lights when you leave a room to save energy, your graphics card might be doing the same thing with its fans. 

When your computer isn’t working super hard or getting really hot, the fans might be programmed to stop spinning to keep things quiet and save some electricity. 

Many graphics cards even have settings you can adjust to control this behavior.  However, some cards might have these settings locked down, so you can’t change them. 

The key thing is, if the fans kick in when your computer needs a little extra muscle, everything is working as expected! 

The engineers who designed your graphics card knew it wouldn’t always need to be on full blast, so they built it to be smart about its cooling needs.

2. Restart Your Device

If there was a software conflict causing your fans to stop spinning, restarting may help remedy it quickly and easily.

Once your PC or laptop is off, simply remove all plugs for an extended period and hold down the power button until all residual power has been used up before plugging everything back in and restarting it all.

3. Verify Fan Power

Does your graphics card remain completely silent even during intense gaming sessions? It could be a power issue!

Just like every component in your PC, the fans on your graphics card need power in order to work. There are two areas you should check:

  • The main power cable: To ensure maximum performance from your graphics card, ensure the main power cable is tightly plugged into both ends.
  • Extra Power Connectors: Graphic cards that require extra juice may have extra power connectors on either the top or back, which have separate cables connecting back to your power source and should always be plugged securely into place. Please make sure these are connected before operating your graphics card!
  • The power connector on the card itself (for some models): For some graphics cards, there may even be a smaller power connector directly attached to them that supplies power directly to fans – this cable could be loose or damaged and be the reason your fans won’t spin properly.

4. Clear The GPU’s Dust

Since you already have your computer open to tinkering around, this is a great time to give your graphics card a little dusting! 

Just like a dirty air filter makes your furnace work harder, a thick layer of dust can make your graphics card’s fans struggle to spin. 

Of course, if you just bought your computer or graphics card recently, you can probably skip this step for now.

5. Reset Your Fan Curves

Did you know some graphics cards come with their own special program?  Think of it like a personal assistant for your graphics card’s fans.

This program lets you control how fast the fans spin depending on how hard your computer’s working and how hot it’s getting.  This is called a “fan curve.”

You can use this program to find the sweet spot between keeping your computer cool and keeping it quiet.  But sometimes, these programs can get a little confusing. 

If your fans are acting weird, try giving them a reset with this program and see if they don’t go back to normal.  It’s like rebooting your phone when the apps start acting buggy!

6. Update Graphics Driver

Your fan not spinning issue may be due to an outdated graphics driver; visit NVIDIA or AMD websites and download and install their correct installer before updating manually.

  • Download and install Driver Easy.
  • Launch Driver Easy and press the Scan Now button; Driver Easy will then scan your computer for any missing or outdated drivers, and notify you.
  • Click “Update All” to automatically download and install all drivers that are missing or outdated on your system.

Once your drivers are updated, restart your PC and check that the fans spin freely now.

How Do I Check My GPU Temperature?

You can check your GPU temperature using the following methods:

Windows Task Manager: Built into Windows 10 and 11, this feature can help monitor GPU temperature.

Here are the steps for monitoring GPU temperature using Task Manager:

  • Press Ctrl + Shift + Esc to access Task Manager.
  • Once open, click on the Performance tab
  • and then GPU Temperature on the left-hand side.
  • It should be displayed on the right as well.

NVIDIA GeForce Experience: If you have an NVIDIA graphics card, the GeForce Experience software allows you to monitor its temperature.

AMD Radeon Software: If you own an AMD Radeon graphics card, use the Radeon Software to monitor its temperature.

Third-Party Tools: Third-party tools also allow for monitoring GPU temperature. Popular examples are MSI Afterburner, EVGA Precision X1, and HWiNFO64 – each offering more precise information as well as features such as overclocking or recording temperature data.

Conclusion

Don’t sweat a silent GPU fan! This guide took you through easy fixes to get those fans whirring again, saving you money and a trip to the repair shop.

From checking for dust bunnies to software updates, we’ve got you covered.  So grab some compressed air and follow these steps to get your computer running cool and quiet in no time.
