How to Fix Computer Fan Loud Voice

Well, a loud fan in your PC is irritating, especially if, just like me. Then you have a big old tower along with a total of nine fans inside it sitting on the desk near your head actually. There are many times when you have to bite the bullet and accept that your PC will sound just like a light aircraft. Like when you guys are doing temperature-raising activities such as gaming and video editing. At these times, fans should kick into gear according to your computer settings, and increase their speed (RPM) in order to blow all that hot air out of your PC. Let’s now discuss How to Fix Computer Fan Loud Voice.

However, during standard daily usage, your fans should run nice and quietly. As browsing, the web and writing emails isn’t exactly going in order to melt down your PC. Here’s how you can take control of loud fans on your PC, adjusting their settings in order to suit you.

How to Fix Computer Fan Loud Voice

Dust, dirt, and other contaminants in the air can actually have an impact on your fan’s performance. However, there are other problems that can crop up, which is why regular maintenance is important. If your PC fans are getting loud, then here are some troubleshooting tips you can try to fix this problem.

Clean Your PC

If your fans are louder than usual during daily usage, then consider that perhaps they are having to work extra-hard. Because a) they are clogged up along with dust or b) Your PC components are basically covered in dust, overheating more, therefore forcing your fans to work harder. Or maybe it’s both as well.

Really, you should be opening up your PC and blowing it out along with compressed air each and every couple of months in order to keep it in good working order. (I do it about every three months, that admittedly isn’t really great). Just open up your PC, blow the dust away, and then see if that helps your fans (Remember, don’t shake compressed air canisters before using them – they’re not graffiti cans as well).

Move Your PC Or Laptop For Better Airflow | computer fan loud

Where you place your PC or laptop is important, because it can determine. If or not your computer fans have the right airflow in order to keep your machine cool. You guys aren’t likely to stick your PC fans by a heater or radiator, however, you may place your PC in a desk cupboard, with the fans stuck at the back.

This is really bad for your PC, as it offers a more limited supply of air to your fans. That causes the air around it to heat up instantly. Hotter air basically means a hotter PC, the harder your fans will have to work to keep your PC cool, that will lead to louder computer fans actually. The same principle applies to a laptop placed on surfaces that can also block your fans.

Change Fan Settings in the BIOS

The majority of PC fans out there basically connect directly to the motherboard. That by extension means that your motherboard controls them. Most of the modern motherboards offer really comprehensive fan control, although how exactly to do this will vary via brand. Still, the same basic principles apply, so for reference, I’ll show you how you can control your fans via my ASUS Z-97 Gamer mobo.

When your PC is booting, repeatedly tap on the “Delete” key (or whichever key you have set to go into your BIOS) to enter your BIOS.

From your BIOS screen, head to “Manual Fan Tuning” where your fans should be listed. Here you can set many power/noise profiles, that you can choose, and quickly hear if they make your fans quieter. Keep in mind that a silent profile doesn’t have to come at a cost of higher temperatures. It just means that the default speed of the fan at low temperatures will be lower actually. It will still speed up whenever temperatures in your case get higher. Keep your ear close to your PC so that you can learn which fan in the BIOS corresponds to which fan in your chassis actually.

You’ll also notice that you can switch every fan between PWN (Pulse Width Modulation) and DC (Direct Control) options. PWN fans mostly have four-pin connectors and can save energy (and cut down on noise) via functioning at lower RPMs/speeds. Mostly, if you guys want to set a quieter noise profile, then go for PWN when possible.

When you do that, then click “Save & Exit” to reboot your PC with the new settings.

Laptop Users: Use A Laptop Cooling Pad

If you are having laptop fan problems, then you may not be able to get as much access to your fans just as you would with a desktop PC. There are also options available if you are scared to take your laptop apart. That includes the option to use an external laptop cooling pad.

A laptop cooling pad (or laptop cooler) is actually a set of external fans. That you can place your laptop on, drawing the heat from the motherboard and also forcing it away underneath. It physically raises your laptop higher, making sure good air flow beneath your laptop for your fans to effectively cool it as well.

This is a really good way in order to keep your laptop cool if you don’t want to attempt more serious maintenance.

Check Running Software | computer fan loud

Computer fans mostly kick in the hardest whenever your PC is running the most intensive applications. If your PC fans are loud when your PC is idle, that could point to a problem with software or malware. For instance, some types of malware (like crypto miners) use your idle PC for other purposes. You guys may not be aware of an infection, which is why it’s necessary to scan for malware regularly on your Windows PC.

If malware isn’t the cause, then just check any running processes via the Windows Task Manager. That you can open through tapping Ctrl + Shift + Esc on your keyboard. Under the Processes section, you’ll also see a list of active apps and background processes and any resource usage as well.

In case, if your CPU or memory percentages are stuck at 100%. Then that’s an actual sign that your PC is working in overdrive, and you’ll have to stop, turn off, or uninstall any overactive apps that are basically causing the problem.

Use a Fan Control Software

If your PC fans are too loud, then you could use third-party fan control software in order to lower their speed. Be advised, but, that this isn’t a good idea if your computer has a problem. Along with the heat that your fans aren’t solving. Well, as a PC or laptop that is too hot can become damaged too.

Most motherboard providers such as MSI offer their own fan control apps. However, a good third-party app for Windows users is SpeedFan. This app will permit you to see your current PC temperatures and tweak your fan speeds, relying on your device’s needs.

If you decide to decrease the speed on your fans, monitor your PC temperatures carefully. If the temperatures remain too high, then you’ll have to restore the settings. That you have changed to make sure your fans can cool down your PC effectively.

Replace Your Fans

If you’ve tried everything else, then there’s only one option left: it’s time in order to replace your computer fans. Just like all other PC components, fans don’t last forever, also even with regular maintenance.  One problem with older PC fans is because of the ball bearings used to turn the blades. After regular use, these lose their lubrication, which makes your computer fan louder.

Thankfully, desktop PC fans can mostly be replaced really easily. As fans like these use common sizing and plug directly onto your motherboard or into your power supply as well. If you replace laptop fans are usually much trickier, as these are designed specifically for certain laptops in order to fit the smaller casing.
