Why Your GPU Fans Are Not Spinning? Here Is a Complete Guide

GPU fans are essential for the longevity of your graphics card, but if they aren’t working properly or spinning consistently- it can cause problems. Luckily there are some quick fixes that will get you back up and running in no time!

One common issue arises when a user notices their GPU fan is slow to spin or not at all; this might be an indication something else may need attention first, like dust buildup on them, which also causes increased drag from heat generation as well as vibration conveying through computer parts (which could lead to more serious damage). So how do we fix these issues? Well, take off any obstructions near where you’ll locate the device, then use compressed air such as canned hairspray bottle type tools

Idle mode

PC users who are curious about their PC’s speed and temperature can check if the fan is off by running a program called MSI Kombuster. This app, which comes with all versions of Nvidia’s GeForce Experience software in addition to its separate executable file for those without access to update consoles through an online service like Game Optimization Dragonfly-tech, also has other uses such as monitoring your gaming graphics card power consumption levels so that you don’t overclock too high while playing games or using applications that use more than 100 watts per second (w/o Metro 2033).

The fan is a vital component of cooling your PC. Without it, you might as well just be playing with an oven! When under load or when the temperature approaches its maximum limitations (usually set at around 60 degrees Celsius), this little guy will start working quickly and efficiently to provide cool air for gaming rigs all over town – saving our hardware from burning up in their clutches like never before!!

Change the power cables

If you recently installed a new GPU only to find the fan isn’t spinning, then there is a 75% chance that your power connector links it with the PSU unit or pins are out of alignment.

Another problem could be insufficient wattage provided by PSUs, which might force us to buy one for our system! Make sure all these things match up before plugging in any devices – check their documentation on how much total watts they require, so make sure those go above and beyond what’s being asked here first just in case something goes wrong later down the road.

Lubricate the fan 

WD-40 is not the best lubricant to use on your graphics card. It can leave a residue that will hinder its functionality or evaporate too quickly and be useless, so avoid using household cooking oils like olive oil! For an easier option, try some baby shampoo; we recommend spit shine because of its low volatility rate (and cost).

Useful tricks include popping out the top cover from where you purchased it before adding any new fluids into the system – this will let air flow through everything while giving access for cleaning up obvious spills around fans, etc, then pour small amounts at a time onto bearings until needed again. Remember always replace cap after usage


GPU fans can often become stuck due to dust and debris that accumulates over time. This is a problem because they are responsible for moving hot air away from the GPU, which creates more issues with particles getting inside your PC when it’s not used regularly.

The most common culprits of this phenomenon are buildup on blades; however, even if you don’t see any obstruction at first glance, there might still be something preventing airflow internally within graphics cards themselves!

Change the fans

Faulty fans and broken PCI-E slots aren’t the only causes of blade issues. A faulty motherboard could also lead to this issue, specifically if there is a bug in your system’s slot or as a whole. You can test out which component might be at fault by shifting your GPU into another one while still on stock speeds (or lower), seeing if it resolves any problems for you!
