As handy Surface Book 3 is, have one annoying flaw also: the tiny fans that keep them cool can become annoying loud for no apparent reason.
A 15-inch Surface Book 3 which starts at $1,189, doesn’t worth it if its fan made a louder noise than usual or makes strange buzzing. These sounds usually indicate that a fan isn’t working correctly a possibly serious problem. If you’re experiencing this, this article is for you because we’ll help you get to the bottom of the problem and describe several effective solutions that you can use to make your laptop fan quiet.
The Most Common Causes of a Microsoft Surface Book 3 Fan Noise

Fans throughout the computer help remove the large amount of heat generated by the CPU, graphics card, power supply, and other hardware on your computer. When heat builds up inside the computer, those parts heat up until they stop working…often permanent.
Some laptop fans are naturally noisier than Surface Book 3. Still, when a fan’s noise transforms from a buzzing to a roaring fighter jet, a specific cause is most likely responsible. The following are the primary Surface Book 3 loud fans’ main causes.
Demanding software
You can’t expect to play the latest Fifa on your laptop without your CPU producing a lot of heat and your fan spinning as fast as possible to perform it, also creating a lot of noise.
If you only have problems with too much fan noise when running heavy software on your laptop, consider yourself blessed because many people have it much worse. You can use some of the solutions described in the following section of this article to assist the fan in performing its function.
Allow your computer to breathe
Monitoring the temperature of your laptop is as important as protecting it from damage. It is generally a good idea to do this on a regular basis in order to increase the lifespan of your computer.
A Laptop built to work in temperatures below 80 degrees Celsius (176 degrees Fahrenheit) is far more reliable than one that exceeds this limit. If the temperatures of your components exceed that, you may have an overheating laptop.
Room temperature
The cooler the temperature of the room, the easier it is for the fan to control the temperature inside the Surface Book. As a result, working or gaming outside during the hot summer months may seem like a good idea with this beast.
Physical objection
Just as a hungry engine cannot produce full power, a fan with physically covered vent holes cannot bring enough fresh air into the chassis to reduce the heat generated by the components it protects. Dust is a common problem that you can’t take lightly.
Malware
Malware can play a part in loud fan noises by increasing a laptop’s temperature and causing it to fail to take commands correctly. A good antivirus is an essential security and PC maintenance tool that should never be missing from your laptop.
Many malware strains are designed to rob computing resources in order to mine cryptocurrencies or launch coordinated cybercrime attacks. All of them, like spyware and Trojan horses, are guaranteed to make your CPU run hot and your fan spin as fast as it can.
Heavy Multitasking
You can consider yourself a heavy multitasker if you never have fewer than 10 web browser tabs and at least 5 applications open at the same time. Heavy multitasking Surface Book 3 can be a common cause of laptop fan noise because running several demanding applications can have the same performance impact as running one demanding application.
Poor Air Circulation
No matter how powerful your Surface Book 3 fan is, it will not work correctly if there is insufficient air. Because most Microsoft laptops have fans at the bottom, you must notice where you hold your laptop. For example, if you keep it in your lap or on a pillow, you are almost restricting the airflow to the fan.
How to Quiet a Noisy Surface Book 3 Fan

Investigate the Software That Is Running
Before you touch a screwdriver, explore what software is currently running, what resources it is digesting, and whether that fan noise is appropriate. To open the Task Manager on a Windows machine, press Ctrl+Shift+Esc and then click the More Details button. It may also be beneficial to download a program such as Core Temp (Windows) to verify whether your CPU is overheating.
If the fan noise only appears when you’re doing something promising, such as gaming or converting a large video file, that’s the ideal activity, and it’s time to investigate the hardware.
Configure Fan Control
If your fans are connected to the motherboard of your surface, you may be able to control them through the BIOS. When your laptop boots, press a key, usually DEL, F2, or something similar, to enter the BIOS menu. Then look for the section on hardware monitoring (or something similar).
Because each BIOS is a little different, we didn’t drive you through the exact steps—some will only offer primary “high” and “low” fan settings. In contrast, others may offer advanced fan curves that allow you to set the fan speed at different CPU temperatures.
Remove the Dust
Grab a screwdriver, open up your laptop, and dust it with an air duster or an electric duster if things are really bad. If your fan is making a clicking or other unusual noise, check to make sure the blades aren’t clashing with an accidental power cable or something similar. Finally, in your Surface Book 3, simply install Filter fans to prevent future dust buildup.
Disable Connected Standby
Disabling “Connected Standby” (CS) is as simple as flipping one registry flag.
- Launch the registry editor from the start menu (regedit.exe)
- Find the “HKEY LOCAL MACHINE/SYSTEM/CurrentControlSet/Control/Power” .
- Set the “CsEnabled” key to 0. (zero).
- Reboot
Scan for Viruses
If you have malware or viruses on your system, they may put extra tension on it by running unwanted processes. It can even crash the drivers and system files that keep the hardware running smoothly. As a result, the fan may have to work harder, making noise.
You should scan your system for viruses using the built-in Windows Defender tool or paid antivirus software. To protect the system from viruses, Microsoft Safety Scanner, and Malwarebytes can be the best options for surface book series. If the software detects a malware, you can remove it. To protect your system, we recommend that you run the scan on a regular basis.
Use Original Thermal Paste
Thermal paste is used in Laptops to fill small air gaps on the processor’s surface and improve heat transfer. After a while, the thermal paste is applied to the bottom of the fan or the top of the CPU wane. As a result, the CPU or GPU overheats, increasing the load on the fan.
Buy a Cooling Pad or External Fan
Perhaps not the most elegant or cost-effective solution in the world, but undeniably effective. On sites like Amazon, there are countless laptop cooling pads and external fans to choose from, and they all can do the same thing: they keep your laptop from overheating by actively blowing cool air on it with an additional fan.
Check the Cooling Pad Form Amazon
You can think that using an additional fan to fight noise issues caused by a different fan is unnecessary, but it can be a solution because laptop cooling pads and external fans are typically much quieter than laptop fans, so the extra noise they create greatly reduces the fan noise reduction.
Replace The Fan
Is your Surface Book 3 fan still making noise after you tried everything?
If the sounds persist after applying all of the fixes, it needs a replacement. When the bearings inside your fan become loose, the fan blades do not sit tight on the bracket as they should.
Shaking sounds or a loud buzz indicate that the fan has been used for too long and the bearings have failed. Although the old fan can be repaired, replacing it is more cost and time efficient.

Nobody likes a loud fan
To summarize, if you’re not doing anything intensive right now, your Task Manager CPU usage should be low—less than 20%. If your computer is idle and your CPU is using 100% of its power, look through the list to see which program is programming those cycles.
A loud laptop fan is more than just annoying; it’s a hint that something is wrong. Noisy fans are often linked with overheating, which can damage the hardware and impair device performance. A loud fan can be caused by a number of factors, and the sooner you address the issue, the better.
