GPU Fan Not Spinning [Resolved]

Everything You Need to Know

gpu fan not spinning

When you switch on your brand-new computer and see there is something wrong with the GPU’s fans, it is obvious that you’ll panic. Also, in some instances, you may notice that the fans are no longer functional when your game shows a slower performance and the graphic cards are starting to stutter. 

There can be multiple reasons behind the graphic card not being functional, besides just the GPU’s fan; for instance, the graphic card may not be adequately seated or connected to the power supply. 

If you have just invested in the best GPU, it is natural for you to be concerned for the first build not to function correctly. There can be various ways to solve the problems with the GPU fans, which are at times very simple and can be easily fixed. 

You can fix them at home without opting for a new fan or an upgrade. Let us explore why the GPU fan of your computer is not spinning and its possible fix. 

GPU Fans Are Not Spinning? Few Things to Know

The first and the most common mistake that a first-time builder makes is to check if the fan is connected correctly to the power supply. You will often come across the term ‘idle’ while you are web browsing for a possible solution to fix your GPU’s fan on the internet. 

The term idle is associated with GPU fans is because it is a common characteristic of modern GPUs to sit on idle mode. Graphic cards are designed to function when they hit a specific temperature. It is designed with a passive cooling system to save power and to keep the noise down.

Now, if you wish to check whether your GPU fans are functional, you can put it to a stress test by turning on a graphically demanding game. This is put some load on the GPU software and should make it startup. You can also install an MSI afterburner if you wish to raise the speed of the fan manually. 

The MSI afterburner is the best thing to install alongside a program as it often acts as a catalyst and might help to get away from the problem. It is genuinely used to overclock the GPU, but in this case, you can use it for monitoring too.

Post this if the graphics card fan does not start even after the card gets hotter, there is likely a problem. At this point, you may want a pc restarting which at times works wonders. 

The Other Issues That Can Stop Fan from Spinning

It often happens with most first-time builders that the PCIe cable is not correctly connected to the power supply or is not precisely ‘seated.’ The first thing to do is to disconnect the cable and remove the side panels to take a closer look. You must also check if the graphics cards are well connected to the power supply unit. 

There are, however, a few exceptions, like GTX 1050 and GTX 1050 Ti do not have a 6 or 8-pin PCI e slot as they can run solely off the power provided through the PCIe lane. 

Therefore, if you do not have a graphics card that needs to get connected to a PCI e slot and the GPU fan not spinning, there is a probability that it can be a faulty one. 

It is a no-brainer that you must double-check all the connections are properly connected and seated correctly. If all other components in your pc are working and just the GPU fan is not spinning, there is a possibility that it can be a faulty component. 

Next Steps of Detecting the Issue

If you are finding no fault in the connections are everything looks as it’s supposed to. There is still no rotation in the GPU fan, usually or under the stress test; lets us consider it to be a faulty component and carry on the following next steps of detecting the issue. 

Updating the Drivers

When you face a hardware issue, it is always suggested to keep all the drivers updated. That way, you can fix the problem by simply rebooting the system. If you have recently updated the drivers, you have to delete them and reinstall them as sometimes they may be bugged or corrupted.

Connecting to A Working Power Supply Unit

If you have access to a known PSU which works, you may have to install that and check if the GPU fan or the graphics card is turning on. If yes, then the power supply unit was faulty. Try switching the graphic card to a different PCI e lane and check if that is working. And if it still doesn’t work, then the graphic card or motherboard can be defective. 

Installing in A Different Computer

Although it is improbable, you can install the graphic card and check if it works if you have access to a different computer. If it does, then your original motherboard has gone bad. And if not, then you may need a new graphics card. 

Cleaning and Maintenance

The most crucial step is that you must remove the GPU. After that, you take out the graphics card and quickly remove the dust as there must not be anything physically blocking the GPU fan. You can use a dust cloth to clean the parts of your PC, which are very important. 

After cleaning the GPU, you can reinstall the card, re-cable, and restart your system. Now you should load a high graphics game and patiently wait for the fan to run.

The card should be cleaned, especially in the old cards the fan bearings might wear, which makes them a little stiffer than when it was at first fresh out of the factory. 

For running smoothly, a small quantity of oil can sort out a mechanical barrier. But you should make sure that it is a lightweight machine oil, which also goes with the name lubricating oil, and you must not use WD40! 

For adding the oil, you must remove the plastic fans. And to do that, you will need a tiny screwdriver that can easily fit in between those blades. 

For extra assistance, you can also look up online to remove the fans on your specific graphics card, but generally, there are 6-8 screws around the center of the GPU fans. It is easier to dismantle it and continue the whole process. 

Once the fans are off, you should apply little oil to the fan bearings. You can always wipe out the excess oil with a tissue after using it, as you want a nice coating instead of a small puddle.

FAQs

How do I force my GPU fan to spin?

To make your GPU from idle mode to fully functional mode is by starting your favorite high definition game and making it run for quite some time. After a while, you will notice that your GPU’s temperature has risen, and you will notice the fans start spinning automatically. To increase the fan speed, make sure you play a graphically demanding game.

To make your GPU’s fans spin at all times, you will have to twist the fan’s behavior manually by installing an MSI Afterburner. You have to simply find the ‘Fan Speed’ section and then click the ‘Manual.’ From there, you’ll have access to dialing in your custom fan curve. 

If this old chestnut didn’t do the trick, then you must check whether all your cables are correctly seated. With so many involved in the fresh build, it’s usual that you will miss one loose or missing connection. 

After trying so much, if you still have no luck, try to reinstall the latest drivers, and if you fail in that, then remove your GPU and give it some TLC with a thorough clean.

How do I know if my GPU fan is not spinning?

GPU fans aren’t known for being the quietest things in the world, so a sure-fire way to test if yours are working is to throw on your most graphically dense game and play it on the highest settings. Before much time has passed, you should hear what sounds like a plane taking off in the room. 

Don’t worry, and it’s not a plane; it’s your GPU fans. If you’ve got a top-of-the-range case with a tempered glass panel or two, it might be best to leave it open so that you can hear clearly.

If hearing the stress tests do not suit you, you can just use the Global Wattman program found in the Radeon’ Global Settings’ menu to keep an eye on your GPUs heatsink under load. If your GPU is going beyond 80-85°, and you can’t hear any fan activity, there’s a good chance your fans aren’t working.

How do I know if my GPU is dying?

If your GPU fan is dying, then it will show some abnormal activities such as: 

Crashing – If your GPU seems to be doing an exceptional job one moment and just after few moments if your PC’s motherboard crashes and won’t reboot, then there’s a good chance your GPU is giving up the graphics card. 

On-Screen Artifacts or Excessive Glitching – If you notice that your game is glitching more than it usually does, this could be another sign your GPU will not last any longer. 

Abnormal Performance – Sometimes, if there is any rise in temperatures and the system unable to perform the necessary heatsink, it may indicate that it’s time to replace the thermal paste on your GPU. Still, generally, the paste isn’t the problem. High temperatures, noise pollution, and abnormal fan behavior can be symptomatic of a GPU that is about to stop working permanently. 

Is it bad to have GPU fans running all the time?

You can keep your GPU fans spinning all the time, even though they’re set to 100%, and there is nothing wrong with that. You can run them this way as they’re designed to handle a heavy workload. Only after years of constant spinning, the GPU fan bearings will start to wear off, but at that point, you must be already in need of an upgraded version. 

If your fans are constantly running, it will help keep your GPU temperature way below average, which is excellent. The constant fans spinning can create noise pollution even if you have a case with tempered glass paneling. If you are wearing gaming headphones and a directional mic, it will not cause any problems, but it’s not all that practical in any other circumstance.

Conclusion

The methods mentioned in this article to fix GPU fans are only possible if you have ample time. You must primarily check the power cable and graphics card fan are appropriately connected. If under these multiple stress tests, too, there is a fan spinning issue, and there it is under warranty, you must contact your seller. 

We hope this article gives you some details about the GPU fans of your computer on spinning, but you should always upgrade it to keep your PC safe. GPU fans can make you worry about your PC’s motherboard, which can be very risky. If your GPU fan becomes a faulty product, it must be replaced with a new one. 

You can either go with a lower-range GPU fan or a higher-range GPU fan. If you want the latest GPU card, then you can go for the all-new RTX 20 series cards, which can be your best buying option at a higher rate. This new series will work fine and live up to your imagination while playing a high graphics game.
