除非您使用水冷系统(water cooling system)，否则计算机通常有多个风扇来冷却电子设备。您的系统可能有一个用于处理器的风扇，另一个用于显卡，一个用于电源，可能还有 1-4 个附加到 PC 机箱的风扇。
冷却风扇对于保持系统凉爽是绝对必要的，但它们不应使您的 PC 听起来像引擎。要在噪音和散热之间找到最佳平衡，您需要了解如何控制 PC 上的风扇速度。
风扇(Fan)速度通常根据硬件温度自动控制。当您浏览互联网时，您的 PC 应该相当安静，但当您玩要求很高的游戏时，它会变得很响。但是，如果您的计算机风扇一直响亮(computer fans are loud all the time)或无法启动并且您的CPU变热，您可以快速解决这两个问题。
本文重点介绍控制风扇速度的几种方法。如果您的风扇有问题，请首先正确清洁您的计算机，(clean your computer properly)因为当有灰尘和污垢时风扇会更加努力地工作。清洁硬件后，您可以使用我们的一种方法根据自己的喜好优化风扇速度。
如何在BIOS中控制(BIOS)风扇速度(Fan Speed)
控制风扇速度最直接的方法是在BIOS中进行更改。如果您不知道如何进入 BIOS(how to enter BIOS)，请在继续之前查看我们的详尽指南。
在BIOS(BIOS)中控制风扇速度取决于您的 PC 或笔记本电脑。BIOS版本有很多，每个版本都有不同的菜单和标签。在某些情况下，您将找不到风扇速度控制选项，因为BIOS不支持此功能。一些联想军团(Lenovo Legion)笔记本电脑就是一个很好的例子。您无法控制风扇速度，因为它们连续运行并使用TDP（热设计功率(Thermal Design Power)）。
但是，在大多数BIOS版本中，您需要滚动菜单，直到找到名为“监视器”、“状态”或类似名称的菜单，具体取决于制造商。在子菜单中，您会找到风扇速度控制(Fan Speed Control)或风扇控制(Fan Control)选项。子菜单的标签和位置取决于制造商。
上图是MSI(MSI)主板的风扇速度控制曲线示例。移动这些点以根据温度间隔调整风扇速度。

如何用软件控制(Software)风扇转速(Fan Speed)
如果您对在BIOS中进行更改感到不舒服，请查看软件选项。许多程序允许您通过决定风扇在特定温度下旋转的速度来控制风扇。此类软件还可以让您跟踪硬件的温度、电压和风扇速度，这可以告诉您何时该清洁您的 PC。
但是，在BIOS(BIOS)中调整风扇速度仍然是最推荐的选项。如果您搞砸了，您可以随时重置为默认设置(reset to the default settings)。
SpeedFan是一个强大的工具并且非常受欢迎，因为它提供了许多功能，同时完全免费。按照今天的标准，它的用户界面看起来已经过时和简陋，但SpeedFan提供了很多。作为此类最古老的工具之一，它可以让您监控硬件温度、电压并进行风扇速度配置。它是免费且易于使用的。
您可以选择每个风扇，然后对响应曲线进行调整。如果您主要是在浏览或执行其他要求不高的任务，则可以通过在低温范围内降低风扇速度来使计算机非常安静。
如果您不想手动配置，但您的默认风扇速度失控，您可以启用 SpeedFan 的自动风扇速度(Automatic fan speed)设置。
请注意，此软件不支持所有可用的主板，这意味着它可能无法检测到您的 PC 风扇，因此您将无法进行任何配置。在这种情况下，您应该在BIOS中进行更改或使用风扇控制器。
GPU风扇是您控制的重要风扇之一。根据您的显卡类型，它可能有 1 个、2 个甚至 3 个风扇。如果风扇配置或管理不正确，即使您的GPU处于轻负载状态，您的 PC 也可能听起来像喷气发动机，这就是MSI Afterburner等工具的用武之地。
MSI Afterburner以超频工具闻名于游戏界，可让您控制GPU风扇速度。
默认情况下，您的风扇速度设置为自动，这应该可以解决您可能遇到的任何GPU风扇速度问题。(GPU)如果您对速度不满意，您可以通过单击 A 外观符号来禁用自动(Auto)模式并通过移动滑块来增加或降低风扇速度来进行简单的手动调整。
请注意，无论温度如何，风扇都会以设定的速度工作。如果您设置了低速，则在玩对GPU(GPU)要求很高的游戏时需要小心。
或者，MSI Afterburner还带有风扇速度曲线。要访问它，请单击“设置”(Settings)按钮。
在风扇(Fan)选项卡中，您将找到风扇控制速度曲线。
就像 SpeedFan 的风扇速度曲线一样，图表代表风扇速度和温度。上下或左右移动点可根据特定温度调整风扇速度。
如何使用风扇控制器控制(Fan Controller)风扇速度(Fan Speed)
在过去的几年里，计算机硬件(Computer hardware)变得更加强大，但电力会产生大量热量。要求苛刻的CPU(CPUs)和GPU(GPUs)会增加机箱内部的环境温度，从而对硬盘驱动器或主板等其他组件产生负面影响。您需要额外的冷却风扇来改善气流，因此设置有 3 个、4 个或更多机箱风扇是很正常的，这也使得风扇控制器很重要。
风扇控制器很有用，但许多 PC 制造商忽略了它们。在BIOS(BIOS)中更改风扇速度设置可能很麻烦，并且由于支持问题，使用软件并不总是最好的解决方案。风扇控制器可帮助您控制和组织风扇。
风扇(Fan)控制器，如上图所示，可让您连接多个风扇。无需将它们连接到主板或PSU，而是将它们全部插入控制器。然后您可以使用控制器的软件来调整风扇速度。一些风扇控制器带有物理控件，如触摸屏或拨盘，可让您手动控制风扇。
选择适合您需求的风扇控制器类型。

How to Control Fan Speed on PC
Computers usually have multiple fans to cool off the elеctroniсs, unless you’re using a water cooling system. Your system may have one fan for the processor, another for the graphics card, one for the power supply, and maybe 1-4 additional fans attached to the PC case.
Cooling fans are absolutely necessary to keep your system cool, but they shouldn’t make your PC sound like an engine. To find the optimal balance between noise and cooling, you need to learn how to control the fan speed on your PC.
Fan speed is often controlled automatically based on the hardware temperature. Your PC should be fairly silent when you’re browsing the internet, but it can get loud when you’re playing a demanding game. However, if your computer fans are loud all the time or fail to kick in and your CPU becomes hot, you can fix both issues quickly.
This article focuses on several methods of controlling fan speed. If you’re having problems with your fans, first clean your computer properly because fans work extra hard when there is dust and grime. Once the hardware is clean, you can optimize fan speed to your liking by using one of our methods.
How to Control Fan Speed in the BIOS
The most straightforward way to control fan speed is by making changes in the BIOS. If you don’t know how to enter BIOS, check our extensive guide before proceeding.
Controlling fan speed in the BIOS depends on your PC or laptop. There are many BIOS versions, and each one has different menus and labels. You won’t find a fan speed control option in some cases because the BIOS doesn’t support this feature. Some Lenovo Legion laptops are the perfect example of this. You can’t control fan speed because they run continuously and use the TDP (Thermal Design Power).
However, in most BIOS versions, you need to scroll through the menu until you find a menu called “Monitor”, “Status” or something similar, depending on the manufacturer. In the submenu, you’ll find a Fan Speed Control or Fan Control option. The label and the location of the submenu depend on the manufacturer.
The image above is an example of the fan speed control curve you might find with an MSI motherboard. Move the points to adjust fan speed based on temperature intervals.
The image below shows the fan speed control menu in the BIOS from Gigabyte, the principal being the same.
How to Control Fan Speed with Software
If you’re uncomfortable making changes in the BIOS, look into software options. Many programs allow you to control your fans by deciding how fast they should spin at specific temperatures. Such software also lets you track your hardware’s temperature, voltages, and fan speeds, which can tell you when it’s time to clean your PC.
However, adjusting fan speeds in the BIOS is still the most recommended option. If you mess anything up, you can always reset to the default settings.
SpeedFan is a powerful tool and extremely popular because it offers many features while being completely free. Its user interface looks outdated and rudimentary by today’s standards, but SpeedFan offers a lot. As one of the oldest tools of this kind, it lets you monitor your hardware temperatures, voltages and make fan speed configurations. It’s free and easy to use.
You can select each fan and then make adjustments to the response curve. If you’re mostly browsing or performing other non-demanding tasks, you can make your computer very quiet by lowering the fan speed for low-temperature ranges.
If you don’t want to bother with manual configurations, but your default fan speeds are out of control, you can enable SpeedFan’s Automatic fan speed setting.
Note that this software doesn’t support all available motherboards, which means it might not detect your PC fans, so you won’t be able to make any configurations. In this case, you should either make the changes in the BIOS or use a fan controller.
One of the essential fans under your control is the GPU fan. Depending on your graphics card type, it might have 1, 2, or even 3 fans. If the fans aren’t configured or managed correctly, your PC might sound like a jet engine even though your GPU is under light load, which is where a tool like MSI Afterburner comes in.
MSI Afterburner is famous in gaming circles for being an overclocking tool, allowing you to control GPU fan speed.
By default, your fan speed is set to automatic, which should fix any GPU fan speed problems you might have. If you’re not happy with the speed, you can make a simple manual adjustment by clicking on the A-looking symbol to disable Auto mode and increasing or decreasing fan speed by moving the slider.
Note that the fan will work at the set speed no matter the temperature. If you set a low speed, you need to be careful when playing a game that demands a lot from your GPU.
Alternatively, MSI Afterburner also comes with a fan speed curve. To access it, click the Settings button.
In the Fan tab, you’ll find the fan control speed curve.
Just like SpeedFan’s fan speed curve, the graph represents fan speed and temperature. Move the points up-down or left-right to adjust the fan speed based on specific temperatures.
How to Control Fan Speed with a Fan Controller
Computer hardware has become a lot more powerful in the past few years, but power generates much heat. Demanding CPUs and GPUs increase the ambient temperature inside the case, negatively impacting other components like hard drives or the motherboard. You need extra cooling fans to improve airflow, so having a setup with 3, 4, or more case fans is quite normal, which also makes fan controllers important.
Fan controllers are useful, but many PC builders overlook them. Changing fan speed settings inside the BIOS can be bothersome, and using software isn’t always the best solution due to support issues. A fan controller helps you control your fans and organize them.
Fan controllers, like in the image above, let you connect multiple fans. Instead of connecting them to the motherboard or the PSU, you plug them all into the controller. Then you can use the controller’s software to adjust the fan speed. Some fan controllers come with physical controls like a touch screen or dials that let you manually control your fans.
Choose the fan controller type that suits your needs.
