![]() You’re not receiving a top-secret transmission… until you accidentally are. Sounds coming from your speakers, even when you aren’t playing anything Press Delete as your computer starts to enter the BIOS screen, and look for any fan control settings you can play with-try a lower setting, but don’t set them too low, lest your temperatures get too high. Or, the curves may be set in a weird spot that causes the fans to constantly ramp up for a few seconds to cool the CPU, but then they ramp back down, allowing the CPU to get hot again. Some of your fans may be running at 75 or 100 percent all the time by default, which is unnecessary. If you feel comfortable, you might even want to open up your machine and wipe the dust off the fan with a clean microfiber cloth.įinally, if you have a desktop PC-especially one you built yourself-you may just need to adjust the fan curves in the BIOS. The same happens with accumulated dust, so give the fan grilles a few passes with a dust blower, or better yet, an electric duster. If you’re using your laptop in bed, make sure to put a tray or something solid under it-your clothes, skin, or blankets might be preventing the system from cooling off, making the fans work harder and louder. As a ballpark, if you aren’t running anything strenuous and your CPU is 158 degrees Fahrenheit (70 degrees Celsius) or higher, I’d say that’s abnormal, and will likely cause excessive fan noise. A program like Core Temp (Windows) or Fanny (macOS) can tell you if your CPU is running hot. If your computer is idle and the fan is still making noise, it could be overheating. Close the offending program or run a malware scan to see if that helps. If your computer’s working hard, the fans will work hard to cool it, so you may have a program running in the background you forgot about, or malware eating up resources without you knowing. If the fans in your computer are indeed too loud, start by opening Task Manager in Windows ( Ctrl+Shift+Esc) or Activity Monitor in macOS (under Applications > Utilities) and see if any programs are taking up a large portion of your CPU. Finally, in older computers, check to see if there’s a disc spinning in the DVD drive-sometimes those can be obnoxiously loud even if they’re working properly. You might also want to check your hard drive’s health, just in case, since a drive spinning up and down repeatedly could create a similar sound. If you’re hearing this, there’s a very good chance your machine just needs some cooling adjustment. Your computer is making loud whirring noises If you’re comfortable with a screwdriver, open up your PC and make sure the fans are clear of obstructions. If your computer still has a DVD drive, it could be in the process of failing, and in need of repair or replacement.įinally, in a lot of desktop PCs, a clicking noise could just mean a cable has gotten too close to a fan and is getting hit repeatedly by the blades. One you’ve ruled out your hard drive as the culprit, you’ll need to dig a little deeper to find what’s making the clicking sound. Don’t neglect this: like living creatures, all hard drives die one day. ![]() ![]() If your hard drives are healthy, take the incident as a warning and avoid any unpleasant surprises by backing up your data regularly. Once all your files are safe, consider replacing your drive with an SSD-not only will it likely last longer, but it’ll make your computer run much faster. You may still have some time to do so-occasionally a drive marked “caution” can still run for years, but if it’s making noises, the end may be nigh. Fire up the program, click on each of your drives in the menu, and make sure they’re all listed as “good.” If the application indicates your drive is anything less than that, you should back up all your data as soon as possible. To check your drive’s health, I recommend a third-party tool like CrystalDiskInfo (Windows) or DriveDx (macOS). This sound could indicate a dying disk-do not ignore it. If your computer is making a clicking or grinding sound, or any sort of low-pitched buzzing noise, you should stop what you’re doing and check the hard drive. Let’s start with the most worrisome sound. ![]() Behold the melodic sounds of a struggling computer. ![]()
