The majority of the time, computer fans will regulate themselves, but if they are always running at high speeds, even while your computer is off, you may need to diagnose the issue or change your settings to ensure that your computer is operating properly. A buggy process using up your CPU or leftover charges on your hardware may also be the cause of high temperatures, which can make your fans run more quickly to compensate.
Computer Running Hot
Your computer may be overheating if its fans are always running, even when it is idle or performing simple activities. This can occasionally be brought on by dust clogging the case vents on your computer, which prevents airflow and traps hot air inside. Periodically clean the vents with a can of compressed air to ensure that cold air can enter and heated air can exit. To assist you access more of the dust, if it’s possible, remove the side panel from your computer tower. Ascertain that the space where your computer is located is cool and that none of its sides are blocked from receiving cool air.
While increasing the speed of your computer can give it more power, it will also cause it to become hotter. If your computer is running too hot all the time, it could be damaged. Reset the hardware’s settings to default to undo the overclocking process if it makes your machine overheat. For instance, if you overclocked your CPU, you can frequently reset it by accessing the BIOS of your computer and returning it to its default settings.
Heavy Processor Use
Your computer will produce more heat the more processing power it consumes. Your computer will get hotter and its fans will run quicker to make up for it if you are doing processor-intensive tasks like playing video games with high graphics settings or running several apps simultaneously. Open Task Manager to see what processes are running if you have few programmes open but your fans are still running hot. It’s possible that a buggy task is using a significant amount of your CPU. Terminate any operating processes that you no longer desire, but take care not to terminate any crucial system processes.
Residual Circuit Board Charge
A residual charge that was left on your motherboard could be the root of the problem if your fans continue to run long after you have turned off your computer. You must perform a cold boot in order to troubleshoot this. Completely shut down your computer before unplugging the tower of everything, including the power wire. Remove the battery and unplug the power cord from your laptop if you’re using one. After 30 seconds of pressing and holding the power button, reconnect everything and restart your computer as usual.
Your BIOS’s settings allow you to manage a lot of your fans. Depending on the model of your computer, what you see when you open your BIOS could require some searching. All of your fans won’t be under your control; case fans, for instance, always operate at the same pace. Although precise speeds might not be editable, you can reduce the minimum and maximum fan speeds. If your fans frequently run too fast, lowering your minimum speeds might be helpful since they might not be configured to go any lower.
