Is your GPU fan not spinning at startup? The fans on your graphics card are necessary for keeping your GPU cool, which is critical for optimal PC performance.
It’s worth noting that GPU fans are intended to stop spinning once a certain temperature is achieved. If you’ve recently constructed a new PC and are experiencing GPU fan spinning issues, you’ve come to the perfect spot.
In this article, we’ll explore common reasons behind your GPU fan not spinning and how to fix it.”
Key Takeaways For Fixing GPU Fans Not Spinning on Startup
To resolve GPU fan difficulties, follow these procedures.
- Test the GPU under a hard demand to see whether the fans are whirling. If they aren’t, there may be an issue that needs to be investigated further.
- Reseat the GPU and check the wires to make sure they are properly connected. Then refer to the motherboard and GPU manuals for help.
- Remove any dust from the GPU to avoid accumulation that might impede the fan’s performance.
- Keep your GPU drivers up to date to avoid any software faults that might be causing the issue.
- Adjust the fan curve parameters to ensure that the fans operate at the desired temperature.
- Try the GPU in a different system to see if the problem is with the GPU or other components in your present configuration.
- If all else fails and the GPU is still under warranty, try sending it back to the manufacturer for repair or replacement.
Common Causes Why GPU Fan isn’t Spinning
The first thing you should know before attempting any remedies to resolve the GPU fan not operating issue.
- If the computer is idle or executing non-GPU-intensive tasks, the GPU fans will not run. The idea behind this is to cut down on noise pollution and to run fans only to keep the safe GPU temperature range.
- The GPU fans stop running when the power connector linking to the PSU isn’t connected or pins are not pushed into the card.
- If the GPU is not correctly sitting in the PCI-E slot on the motherboard you are likely to face a graphics card fan not spinning problem.
- Insufficient wattage supply from PSU is another cause. Consider investing in a more powerful power supply unit.
- Check the overall connection that may get loose on the motherboard. Ensure that all wires are properly plugged in and seated.
Tip – Older GPU fans usually stop working due to dust and debris on the blades. The use of compressed air can solve this problem.
How To Fix GPU Fans Not Spinning on Startup After Boot
1. Update GPU Drivers

If you have checked the cables and everything is OK, still GPU fans won’t turn on. then you should start with updating graphics card drivers.
Even if you have updated GPU drivers recently still it’s recommended to delete and reinstall once more to fix any bug.
NVIDIA users can download GeForce Experience while AMD users can download Radeon Software to update their GPU drivers.
2. Replace/Upgrade Power Supply Unit
The GPU fans may not be operating because your existing PSU is underpowering the GPU. To apply this fix buy a power supply unit and mount a GPU on it to check if the fan starts spinning.
If it turns on then there’s a problem with your current PSU.
3. Install GPU on a Different Motherboard or Change PCIe Lane
It’s not always the faulty GPU fan that prevents blades from running. A broken motherboard or buggy PCIe slot can also be a problem.
Install GPU on a different PCIe lane and then on a different motherboard. If you are facing with GPU fans stop spinning problem, which is resolved then your motherboard is bad. You need to buy a new motherboard.
4. Boot Up Your PC Without GPU
Running your computer without the graphics cards installed on it can give you a hint if there’s a problem with your motherboard.
So you need to remove the GPU and turn on the PC and if it boots up just fine. It means that your motherboard is not at fault.
Furthermore, try running a stress test in such a situation to see if any problem pops up or not. If everything is fine then it is possibly your PCIe Slot or PSU at fault.
5. Replace GPU Fans

If you have gone through all the above steps and the GPU fans still not spinning then you need to replace them GPU fans. Noctua, Cooler Master, and Corsair are the finest companies that provide adequate GPU fans at reasonable rates.
How To Check If GPU Fan is Faulty?
If you have realized that your GPU fan not spinning then you need to check if there’s any fault.
Install and run a GPU Benchmark software on your system. This tool will put a lot of stress on your GPU. While your GPU is under load, also download fan control software to increase GPU fan speed. One of the best tools is the MSI Afterburner install it and Change the GPU fan speed manually.
If the GPU fan does not spin when the benchmarking program does a stress test. Even though manually changing fan speed doesn’t affect GPU fan spinning.
Then your GPU fans are faulty. To fix them first check the common causes explained above and fix them or buy the new GPU fan.
What Might be the Cause of a Black Screen Right After you Install a New Graphic Card?
If you have recently installed a new GPU or updated its driver and when you boot up the PC you may see a black screen. It’s usually due to the following reasons;
- No graphics card is detected.
- The onboard GPU is not disabled in BIOS.
- You have installed the graphics card in the wrong slot.
- The graphics card has insufficient RAM.
Solution: Black Screen Appears After Installing a New GPU
Here are the procedures to resolve the no display with graphics card plugged in issue.
- First of all you have to turn off your computer and then unplug the power cable.
- Remove GPU.
- Plug the monitor into your video output.
- Turn on the computer.
- Click on start type msconfig within the Boot tab and click on the box that says Safe boot with minimal selected.
- Apply then click OK.
- Do not Restart your PC yet.
- Shut Down the computer and unplug it it.
- Install Graphics card.
- Turn on the computer and it will boot into safe mode.
- Go into Device Manager.
- Expand Display Adapter.
- You have to disable the Intel(R) HD Graphics 4000 driver. (Do Not Uninstall)
- Click the start button and type msconfig.
- Unclick Safe boot.
- Restart.
Your PC will run without showing a black screen. Just make sure that you haven’t installed two GPU drivers.
How To Fix the PSU Fan Not Spinning Problem
Is your power supply fan not spinning at all or even when you have played high-definition video? Most PSUs don’t run the fan in case of internal PSU temperature is low.
If your overall CPU temps are fine, then you are in a safe zone. The PSU fan only turns on for a second when you boot up or shut down the PC. The PSU fan will only turn on when enough power is used and it needs some cooling.
The fact that the PSU fans spin occur when you power on PC, shows that the motor is working fine. Also, it isn’t drawing enough of a load to necessitate the usage of the fan during operation.
Is it Bad to Run Your GPU Fan at 100 All the Time?
Running GPU at full speed is good for GPU to perform at optimum level. However, at 100% GPU fan RPM, the bearing will soon wear out as all fans do.
So it’s wise to download fan control software that lets users set custom fan curves. This way GPU fan speed will increase according to internal heat.
Fix: EVGA GTX 960 Fans Not Spinning
GTX 960 is an ACX Cooling card, so it won’t turn on until the GPU temperature reaches 60C. Once the temperature goes idle the fan turns off itself.
To fix this problem first make sure that the fan spins after you boot up your PC.
However, you can fix this problem by downloading MSI Afterburner software. These tools override the fan control resultantly the fan will start spinning.
