Any issues with the power cables could cause their fan blades to stop working.<\/p>\n\n\n\n<p>Remove your fan header and check whether the cables from the power supply unit are connected correctly.<\/p>\n\n\n\n<p>Most CPU fans require either 3-5 to 12 volts. If the four-pin connection with the PSU is not correct, you might be getting less than the required volts. You can use a volt meter to make sure.<\/p>\n\n\n\n<p>Simply remove and reattach the PSU into the appropriate slots if it has been wired incorrectly.<\/p>\n\n\n\n<p>While on the topic of power supply, make sure your motherboard has not short-circuited. It won't be able to power your case fan otherwise. You'll need to contact a professional for help.<\/p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How To Find Short Circuit Onboard CPU\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Oe7gJ0XerkE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Solution_7_Replace_the_CPU_Cooler_Fan\"><\/span>Solution 7: Replace the CPU Cooler Fan<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>It might be time to get the fan replaced if it's still not working. You're probably dealing with a hardware problem. The damage could be a manufacturing defect or due to an accident.<\/p>\n\n\n\n<p>Hopefully your warranty will cover the damages for you.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Should_CPU_Fans_Ever_Stop_Spinning\"><\/span>Should CPU Fans Ever Stop Spinning?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>CPU fans should not stop spinning (while the computer is still on), because once they do, your desktop computer will start to overheat. It will reach dangerous temperatures if you run a lot of graphic-extensive programs.<\/p>\n\n\n\n<p>Immediately look for the source of the issue if your PC case fan has been giving your trouble. As mentioned, the problem could be due to there not being enough energy supply, or dust stuck between your fan blades.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Can_a_PC_Work_Without_a_Fan\"><\/span>Can a PC Work Without a Fan?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Your computer can't work without a cooling system. Instead of a PC case fan, you can go the water cooling route. The idea of having water anywhere near your computer might sound risky, but it's actually better than air cooling. I've touched on this in the section below.<\/p>\n\n\n\n<p>If you don't have water cooling or any other type of cooling to replace your fan, then your PC won't work.<\/p>\n\n\n\n<p>It might start at first, but it will soon shut down as it might be too overheated to stay on.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_Long_Do_PC_Fans_Last_For\"><\/span>How Long Do PC Fans Last For?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can expect a PC fan to last for 3-6 years. Some users have reported that they can last for around 10 years without any issue.<\/p>\n\n\n\n<p>To get the most out of the device, you will have to take care of it and do proper maintenance (clean it so that you don't have to worry about even the smallest particles getting stuck).<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_Do_You_Check_if_Your_PC_Fan_is_Working\"><\/span>How Do You Check if Your PC Fan is Working?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can usually tell if there is something wrong with your fan by opening the PC case and inspecting it (remember to also inspect the CPU bearing that the fan is connected to).<\/p>\n\n\n\n<p>Or, you can check whether there are any issues by observing how your computer performs. If it's particularly sluggish or keeps turning itself off, there may be something wrong with your cooling system.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_Fast_Should_Case_Fans_Spin\"><\/span>How Fast Should Case Fans Spin?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The answer to this depends on the particular model you have.

You may have either broken the fan hub or could be dealing with a default hardware fault. Your warranty should cover this.<\/li><\/ul>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Why_Wont_My_PC_Turn_On_But_Has_Power\"><\/span>Why Won\u2019t My PC Turn On But Has Power?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Something may be wrong with your PC's power supply. Check whether there are any issues with your CPU power button or the wires connecting it to your motherboard.<\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Should_You_Switch_to_Liquid_Cooling\"><\/span>Should You Switch to Liquid Cooling?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If your CPU fan is not spinning even after you tried out the fixes mentioned, you can take this as a sign to switch to liquid cooling.<\/p>\n\n\n\n<p>Many users find it strange to have water anywhere near their PC, but it comes with some benefits.<\/p>\n\n\n\n<p>Let's talk about them.<\/p>\n\n\n\n<h4><span class=\"ez-toc-section\" id=\"1_Better_Efficiency\"><\/span>1. Better Efficiency<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Water can handle heat better than air due to its high thermal conductivity. Going the liquid route also guarantees that your computer's insides will be consistently cool. A CPU fan only kicks into gear when it detects that your PC has become too hot.<\/p>\n\n\n\n<h4><span class=\"ez-toc-section\" id=\"2_Improves_Overclocking_Potential\"><\/span>2. Improves Overclocking Potential<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Overclocking is when your computer performs at a higher frequency, and speeds up your processor. This is something that gamers do often, as they get a better performance.<\/p>\n\n\n\n<p>However, overclocking can damage your computer because of the amount of heat it creates.<\/p>\n\n\n\n<p>Liquid cooling is all-around better than air cooling, so it can handle overclocking better. This might be what you want to hear if you're a competitive gamer.<\/p>\n\n\n\n<h4><span class=\"ez-toc-section\" id=\"3_Less_Noise\"><\/span>3. Less Noise<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>As you know, desktop fans can be noisy, especially if you have a lower-end model. You don't have to worry about sound if you go the liquid cooling route.<\/p>\n\n\n\n<p>There will be a self-contained water loop inside your computer that stays quiet.<\/p>\n\n\n\n<p>Yes, liquid cooling units do come with a fan. So if you're wondering how there won't be any sound, it's because the fan is small and circulates the air while the water loop does all the heavy lifting.<\/p>\n\n\n\n<p>The fan also operates at a low RPM, so you won't even notice it.<\/p>\n\n\n\n<h4><span class=\"ez-toc-section\" id=\"Are_There_Any_Cons_to_Liquid_Cooling\"><\/span>Are There Any Cons to Liquid Cooling?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Liquid cooling does have a couple of cons, like the fact that it's expensive and more complicated to install. Quite a few users have issues with maintenance as well.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"500\" height=\"350\" src=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/11\/Computer-with-Liquid-Cooling.jpg\" alt=\"Computer with Liquid Cooling\" class=\"wp-image-3053\" srcset=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/11\/Computer-with-Liquid-Cooling.jpg 500w, https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/11\/Computer-with-Liquid-Cooling-300x210.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure><\/div>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Final_Thoughts\"><\/span>Final Thoughts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are many fixes to try in case your case fans stop spinning. You're most likely having trouble with your CPU cooler fan because there is dust or dirt stuck inside. You can get a compressed air can and get your rear case fan to get back up and running again.<\/p>\n\n\n\n<p>However, if your CPU fan is still not spinning, you might be dealing with an interruption in your power supply unit. Check whether there are any cables in the way and remove them.<\/p>\n\n\n\n<p>Of course, your fan headers might be glitching out, so try restarting your computer.<\/p>\n\n\n\n<p>Hopefully you found all the points discussed useful.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You're most likely dealing with dust and dirt stuck in your case fan if it's not working.
