如果您的Windows PC 听起来像喷气发动机，那可能有一个重要原因：嘈杂的风扇。它们听起来可能并不重要，但风扇是必不可少的 PC 组件，需要定期维护。除非您使用水冷(water cooling)，否则您需要 PC 风扇将热量从CPU等组件中排出，以保持它们正常工作。
空气中的灰尘(Dust)、污垢和其他污染物会影响风扇的性能，但还会出现其他问题，这就是为什么定期维护至关重要的原因。如果您的计算机风扇声音越来越大，这里有六个故障排除技巧，您可以尝试解决问题。
给你的 PC 粉丝一个清洁(Give Your PC Fans A Clean)
当您的风扇吸入空气时，它们会将其他污染物带入您的 PC 或笔记本电脑外壳。就像(Just)书柜会不时地在不擦拭和抛光的情况下积聚灰尘一样，如果您不时不时地彻底清洁计算机风扇，它们的声音可能会越来越大。
这在台式 PC 上更容易做到，通常只需简单的过程即可卸下 PC 机箱上的侧面板并接触风扇进行清洁。大多数外壳面板使用几个螺丝固定到位，因此请随身携带螺丝刀。然而，对于笔记本电脑来说，这个过程有点困难。
如果您有信心将笔记本电脑拆开，这将使您可以完全清洁风扇，但只有在您确定时才这样做（并且您不会在此过程中使保修失效）。无论您使用的是 PC 还是笔记本电脑，您都可以使用空气除尘器、压缩空气或特殊的电动空气除尘器真空除尘器来清除积聚的灰尘。
除去灰尘后，您的风扇应该不必再费力地为您的计算机降温，从而使 PC 整体上更安静（如果风扇工作正常）。
移动您的 PC 或笔记本电脑以获得更好的气流(Move Your PC Or Laptop For Better Airflow)
放置 PC 或笔记本电脑的位置很重要，因为它可以确定您的计算机风扇是否有合适的气流来保持机器凉爽。您不太可能将 PC 风扇粘在加热器或散热器旁边，但您可以将 PC 放在桌面橱柜中，让风扇卡在后面。
这对您的 PC 不利，因为它为您的风扇提供的空气供应更加有限，这会导致其周围的空气迅速升温。更热(Hotter)的空气意味着更热的 PC，您的粉丝将不得不更努力地工作以保持您的 PC 凉爽，这将导致更大的计算机风扇。同样的原则也适用于放置在可能会挡住风扇的表面上的笔记本电脑。
为您的台式电脑或笔记本电脑风扇提供足够的空气来完成他们的工作，结果您应该会看到一台更酷的电脑（和更安静的风扇）。
笔记本电脑用户：使用笔记本电脑散热垫(Laptop Users: Use A Laptop Cooling Pad)
如果您遇到笔记本电脑风扇问题(laptop fan problems)，您可能无法像使用台式电脑那样访问风扇。值得庆幸的是，如果您害怕拆开笔记本电脑，可以选择使用外部笔记本电脑散热垫。
笔记本电脑散热垫（或笔记本电脑散热器）是一组外部风扇，您可以将笔记本电脑放在上面，从主板吸收热量并将其从下方排出。它在物理上将您的笔记本电脑抬得更高，确保您的笔记本电脑下方有良好的气流，以便您的粉丝有效地冷却它。
如果您不想尝试更严格的维护，这是让笔记本电脑保持凉爽的好方法。
检查正在运行的软件(Check Running Software)
(Computer)当您的 PC 运行最密集的应用程序时，计算机爱好者通常最努力地踢球。如果您的 PC 空闲时您的计算机风扇声音很大，这可能表明软件或恶意软件存在问题。
例如，某些类型的恶意软件（例如加密矿工）将您的闲置 PC 用于其他目的。您可能不知道感染，这就是为什么定期扫描您的 Windows PC 上的恶意软件很重要的原因。(scan for malware)
如果不是恶意软件，请使用Windows 任务管理器(Windows Task Manager)检查任何正在运行的进程，您可以通过按键盘上的Ctrl + Shift + Esc 打开它。在“进程(Processes)”部分下，您将看到活动应用程序和后台进程以及任何资源使用情况的列表。
如果您的CPU或内存百分比停留在 100%，则表明您的计算机正在超速运行，您需要停止、禁用或卸载任何导致问题的过度活跃的应用程序。
使用风扇控制软件(Use Fan Control Software)
如果你的电脑风扇声音太大，你可以使用第三方风扇控制软件来降低它们的速度。但是请注意，如果您的 PC 存在风扇无法解决的散热问题，这不是一个好主意，因为太热的 PC 或笔记本电脑可能会损坏。
一些主板供应商（例如MSI ）提供自己的风扇控制应用程序，但适用于(MSI)Windows用户的一个很好的第三方应用程序是SpeedFan。此应用程序可让您查看当前 PC 温度并根据您设备的需要调整风扇速度。
如果您决定降低风扇的速度，请仔细监控您的 PC 温度。如果温度仍然过高，您需要恢复更改的设置，以确保您的风扇可以有效地冷却您的 PC。
更换你的粉丝(Replace Your Fans)
如果您已经尝试了其他所有方法，那么只剩下一个选择：是时候更换您的电脑风扇了(fans)。与所有其他 PC 组件一样，即使定期维护，风扇(fans)也不会永远存在。
老式 PC 风扇的一个问题是用于转动叶片的滚珠轴承。经常使用后，它们会失去润滑作用，使您的计算机风扇声音更大。
值得庆幸的是，台式电脑风扇通常可以很容易地更换，因为这些风扇使用通用尺寸并直接插入主板或电源。更换笔记本电脑风扇通常要棘手得多，因为它们是专门为某些笔记本电脑设计的，以适应较小的外壳。
然而，这并不意味着这是不可能的，因为笔记本电脑风扇可以从第三方供应商、eBay 等拍卖网站或制造商本身采购。也(Don)不要忘记保修：如果您的笔记本电脑仍在保修期内，您可以免费要求更换笔记本电脑风扇。
定期 Windows PC 维护(Regular Windows PC Maintenance)
嘈杂的计算机风扇通常是由灰尘和污垢引起的，因此请拿出压缩空气罐，让您的 PC 或笔记本电脑快速吹入干净的空气以清洁它们，这是您常规 PC 维护程序的一部分。大声(Loud)的电脑风扇是过度劳累的风扇，这可能会影响您 PC 的整体性能(overall performance of your PC)。
当然，您的粉丝并不是来自您的 PC 的唯一噪音来源。其他嗡嗡声的计算机噪音(whirring computer noises)可能是由硬盘驱动器等组件引起的，尤其是在驱动器出现故障(drive is failing)时。您的 PC 不会永远独立运行 — 一些常规的TLC有望帮助它在未来很多年保持工作。
6 Tips To Fix When Your Computer Fan Is Loud
If your Windows PC sounds like a jet engine, there’s probably one big reаson for it: noisy fans. They might ѕound unimрortant, but fаns are essential PC components that require regular maintenance. Unless you’re using water cooling, you need your PC fans to draw the heat out from components like your CPU to keep them working.
Dust, dirt, and other contaminants in the air can have an impact on your fan’s performance, but there are other problems that can crop up, which is why regular maintenance is essential. If your computer fans are getting loud, here are six troubleshooting tips you can try to fix the problem.
Give Your PC Fans A Clean
As your fans draw in air, they bring other contaminants into your PC or laptop case. Just like a bookcase will gather dust without a wipe and polish every now and again, your computer fans will likely get louder and louder if you aren’t giving them a full clean once in a while.
This is easier to do with a desktop PC, where it’s usually a simple process to remove the side panel on a PC case and gain access to your fans for cleaning. Most case panels stay in place using a few screws, so keep a screwdriver handy. For laptops, however, the process is a little harder.
If you feel confident taking your laptop apart, this will give you full access to clean your fans, but only do this if you’re sure (and you don’t void your warranty in the process). Whether you’re using a PC or laptop, you can use an air duster, compressed air, or special electric air duster vacuum to remove built-up dust.
With the dust removed, your fans should have to work a little less hard to cool your computer, resulting in a quieter PC overall (if the fans are working correctly).
Move Your PC Or Laptop For Better Airflow
Where you place your PC or laptop is important, as it can determine whether or not your computer fans have the right airflow to keep your machine cool. You aren’t likely to stick your PC fans by a heater or radiator, but you may place your PC in a desk cupboard, with the fans stuck at the back.
This is bad for your PC, as it offers a more limited supply of air to your fans, which causes the air around it to heat up quickly. Hotter air means a hotter PC, the harder your fans will have to work to keep your PC cool, which will lead to louder computer fans. The same principle applies to a laptop placed on surfaces that can block your fans.
Give your desktop PC or laptop fans enough air to do their job, and you should see a cooler computer (and quieter fans) as a result.
Laptop Users: Use A Laptop Cooling Pad
If you’re having laptop fan problems, you may not be able to get as much access to your fans as you would with a desktop PC. Thankfully, there are options available if you’re scared to take your laptop apart, including the option to use an external laptop cooling pad.
A laptop cooling pad (or laptop cooler) is a set of external fans that you can place your laptop on, drawing the heat from the motherboard and forcing it away underneath. It physically raises your laptop higher, ensuring good airflow beneath your laptop for your fans to effectively cool it.
This is a good way to keep your laptop cool if you don’t want to attempt more serious maintenance.
Check Running Software
Computer fans usually kick in the hardest when your PC is running the most intensive applications. If your computer fans are loud when your PC is idle, that could point to a problem with software or malware.
For instance, some types of malware (such as cryptominers) use your idle PC for other purposes. You may not be aware of an infection, which is why it’s important to scan for malware regularly on your Windows PC.
If malware isn’t the cause, check any running processes using the Windows Task Manager, which you can open by pressing Ctrl + Shift + Esc on your keyboard. Under the Processes section, you’ll see a list of active apps and background processes and any resource usage.
If your CPU or memory percentages are stuck at 100%, then that’s a sign that your computer is working in overdrive, and you’ll need to stop, disable, or uninstall any overactive apps that are causing the problem.
Use Fan Control Software
If your computer fans are too loud, you could use third-party fan control software to lower their speed. Be advised, however, that this isn’t a good idea if your PC has a problem with heat that your fans aren’t solving, as a PC or laptop that is too hot can become damaged.
Some motherboard providers such as MSI offer their own fan control apps, but a good third-party app for Windows users is SpeedFan. This app will allow you to see your current PC temperatures and tweak your fan speeds, depending on your device’s needs.
If you decide to reduce the speed on your fans, monitor your PC temperatures carefully. If the temperatures remain too high, you’ll need to restore the settings you’ve changed to make sure your fans can cool down your PC effectively.
Replace Your Fans
If you’ve tried everything else, there’s only one option left: it’s time to replace your computer fans. Like all other PC components, fans don’t last forever, even with regular maintenance.
One problem with older PC fans is due to the ball bearings used to turn the blades. After regular use, these lose their lubrication, making your computer fan louder.
Thankfully, desktop PC fans can usually be replaced quite easily, as fans like these use common sizing and plug directly onto your motherboard or to your power supply. Replacing laptop fans is usually much trickier, as these are designed specifically for certain laptops to fit the smaller casing.
That doesn’t mean it’s impossible, however, as laptop fans can be sourced from third-party suppliers, from auction sites such as eBay, or from the manufacturer itself. Don’t forget your warranty, either: If your laptop is still under warranty, you may be able to request a laptop fan replacement for free.
Regular Windows PC Maintenance
A loud computer fan is usually caused by dust and dirt, so get out the compressed air cans and give your PC or laptop a quick blast of clean air to clean them as part of your regular PC maintenance routine. Loud computer fans are overworked fans, which could impact the overall performance of your PC.
Of course, your fans aren’t the only source of noise coming from your PC. Other whirring computer noises are likely to be caused by components such as your hard drive, especially if your drive is failing. Your PC won’t last forever on it’s own—a bit of regular TLC will hopefully help to keep it working for many years to come.
