The infamous “fan noise when starting PC” can be caused by one of several issues. If you’re fed up with the annoying “help me!” growl, here’s what you can do. The best way to fix fan noise is to clean the fans on your PC. Open the chassis, use compressed air or an electric air duster, and wipe the fan blades down with a soft lint-free microfiber cloth. If you’re an animal lover and/or have a dusty office, try this fix. It works on all fans, so don’t limit yourself to one, because a cleaning may be necessary for all.
Problems with laptop and desktop fans
Computer fans may be noisy when you’re trying to start your computer, but the problem usually stems from a faulty CPU fan. The CPU fan is responsible for cooling the processor, so when it stops working, the computer will not start. The fan itself is also prone to wear and tear, so you need to replace it if you notice it’s no longer functioning properly. You can test the fan by using another computer to run tests. You can also try plugging a different fan on the motherboard to see if that fixes the problem.
Another common cause of noisy laptop fans is a program that taxed the onboard RAM. If you’re having trouble with your laptop’s fans, you may want to remove the back panel of the computer and clean the internal components with compressed air. After cleaning the internal components, test the fans again. If the fans continue to run erratically, you should check the fan’s firmware.
Fixing a rattling computer fan
A rattling computer fan noise could be the result of a few different issues. The fan case may be rattling due to dust accumulation. Over time, this can interfere with the fan’s ability to rotate freely. This might require cleaning the fan, but it will probably not fix the noise either. In addition to cleaning the fan, you should clean other components of your PC.
Firstly, you should check if your computer fan is loose. Dust can block the fan blades and cause the noise. If you suspect a loose fan blade, unscrew it from the mounting holes and use compressed air to remove the dust. Once you have removed the screws, you can now take the fan out. Make sure to do this for all fan blades. If this does not work, try using compressed air or an electric air duster to clean the fan blades.
Fixing a clogged air vent
If you hear a clicking, humming, or buzzing sound when you start your computer, you might be experiencing an overheated fan. Fortunately, this problem is easily fixed by spraying sewing machine oil into the bearing. Make sure you spray it before the symptoms occur, though. If the noise continues, you should buy a new fan. Check the CFM and dBA numbers of the computer’s fans to make sure they’re working correctly.
To test whether your computer fan is blocked, place your hand an inch or two from the front or back of the computer case. If you feel no airflow, it’s highly likely that the fan is not moving properly. If your computer fan doesn’t move, try placing your hand over the air vent and listening to it rotate. If you can’t hear it, the problem could be with the fan or the power source.
Using Task Manager to reduce fan noise
If you’re hearing fan noise when you’re starting your PC, you should know that there are a few things you can do to get your computer running more quietly. The first step is to check your Task Manager. If your CPU is using a lot of resources, it’s likely that the fan is being used by programs other than Windows. If this is the case, you can disable the programs that are using your CPU by using the Disable Processes option in Task Manager.
Some software and high-end processes on your computer are also the culprit. For example, playing a game or editing video can cause your computer’s fans to run at high speeds, making them more noisy. If you want to decrease fan noise when starting your PC, make sure to close apps running in the background. You can also try cleaning vents with compressed air. If this doesn’t solve your issue, try removing your AC adapter and battery.
