您已尽一切努力让您的 PC 构建尽可能安静。那么，为什么你的电脑会像疯了一样嗡嗡作响？噪音是从哪里来的？你应该担心吗？
有可能是风扇有问题。如果是这样的话，它可能会导致严重的问题。
风扇怎么了？
电脑(Computer)风扇在那里提供冷却。您的计算机工作越努力，它产生的热量就越多。这就是为什么风扇被战略性地放置在您的计算机上的原因。它们有助于调节内部温度，使您的 PC 继续工作而不会过热。
风扇可以工作多年而不会出现问题。但总会有崩溃的时候。定期磨损会导致风扇随着时间的推移而退化。或者是维护不当引起的。
也就是说，您应该定期清洁它们，以使风扇保持最佳状态。
除尘您的风扇将摆脱大声呼呼。但是请注意，风扇噪音是正常的，尤其是在压力下。
如何清洁电脑风扇
清洁风扇并不像您想象的那么难。它也不需要很多工具。在大多数情况下，您只需要一块抹布和一罐压缩空气。
因此，如果打开电脑机箱让您暂停，请放心，无需担心。
清洁桌面
首先，关闭计算机并将其从插座上拔下。解开所有插入的电缆。
您将吹掉灰尘，因此请考虑将您的 PC 移至开放空间。
使用螺丝刀卸下一个或两个面板，打开机箱。如果您有免工具箱，请解锁铰链以打开面板。
一旦暴露，通过将压缩空气吹入每个角落和缝隙来清洁机箱风扇。
当您使用它时，请注意主板、显卡、硬盘驱动器、电源风扇和其他组件。
小心不要弄乱 PC 的接线。
清洁笔记本电脑
以同样的方式清洁和打开笔记本电脑。使用(Use)压缩空气清除风扇和散热器上的灰尘。
要记住的事情。当用户修补内部组件时，有些制造商会取消保修。如果您不确定如何继续，请联系制造商的技术支持。
完成后，重新连接面板并将所有东西重新插入。打开台式机或笔记本电脑，检查是否仍然有很大的呼呼声。
防止过热
如果您的风扇很干净但风扇噪音没有下降，那么问题可能源于运行太多任务。
简单来说，风扇是在补偿CPU产生的热量。
有些程序太费力了，无法在其他程序之上运行。尝试在不使用时关闭应用程序。您也可以尝试一次运行一个应用程序。
有时您的操作系统会在您不知情的情况下运行后台进程。无论您运行的是 Windows 7 还是 Windows 10，都没有关系。
幸运的是，有一种方法可以找出哪些任务使您的CPU过度工作。您可以使用任务管理器(Task Manager)找到您的罪魁祸首。
按CTRL + Shift + Esc打开任务管理器。如果窗口以简单视图(Simple
View)打开，请单击更多详细信息(More
Details)展开。
转到进程(Processes) 选项卡(Tab)。观察CPU使用率列下的数字。排列列以在顶部显示哪些程序消耗的内存最多。
使用时CPU
百分比不应接近 100%。如果您发现一个在附近运行的程序，您可以强制它停止工作。
右键单击(Right-click)应用程序的名称。单击(Click) 结束任务(End Task)
以停止程序工作。
有一些Windows
应用程序会在结束时停止计算机工作。如果您尝试停止重要进程，您将看到警告。
如果一切都失败了……
那么可能是时候更换你的风扇了。它可能已经退化到任何清洁都无法恢复正常的程度。
PC机箱风扇并不贵。在亚马逊(Amazon)上的快速搜索显示，高评价的选择约为 10 美元。
如果再多的清洁都无法解决呼呼的噪音问题，请考虑更换风扇。
Computer Making a Whirring Noise? Here’s How to Fix It
You’ve done
everything you can to keep your PC build as quiet аs possible. So why then is
your computer whirring like crazy? Wherе is the noise coming from? Should you
be worried?
There is a chance
that there’s something wrong with the fan. And if that’s the case, it can cause
serious problems down the road.
What’s
Wrong With the Fan?
Computer fans are
there to provide cooling. The harder your computer works, the more heat it
generates. That’s why fans are strategically placed on your computer. They help
regulate the internal temperature so that your PC continues working without
overheating.
Fans can work for
years without issue. But there comes a time when it breaks down. Regular
wear-and-tear cause fans to degrade over time. Or it’s triggered by improper maintenance.
That said, you
should clean them regularly so fans remain in tip-top condition.
Dusting off your
fans will get rid of the loud whirring. Do note, however, that it’s normal for
fan noise to occur especially when under stress.
How
to Clean Computer Fans
Cleaning fans is
not as hard as you might think. It also doesn’t take a lot of tools. In most
cases, all you’ll need is a rag and a can of compressed air.
So if opening a
computer case is giving you pause, rest assured that there’s no need to worry.
Cleaning
Desktops
First, turn off
your computer and unplug it from the outlet. Unhook all the plugged cables.
You will be
blowing off dust so consider moving your PC to an open space.
Open the case by
removing one or both panels using a screwdriver. If you have a tool-free case,
unlatch the hinges to open the panel.
Once exposed,
clean the case fans by blowing compressed air into every nook and cranny.
While you’re at
it, give the motherboard, graphics cards, hard drive, power supply fan, and other
components some attention.
Be careful not to
mess up your PC’s wiring.
Cleaning
Laptops
Clean and open
laptops the same way. Use compressed air to remove dust from the fans and the
heatsink.
Something to keep
in mind. There are manufacturers who void the warranty when users tinker with
the inside components. Contact your manufacturer’s tech support if you’re
unsure how to proceed.
Once you’re
finished, re-attach the panel and plug everything back in. Open your desktop or
laptop to check if there’s still a loud whirring noise.
Prevent
Overheating
If your fans are
clean but the fan noise isn’t dropping, then the issue could stem from running
too many tasks.
In simple terms,
the fans are compensating for the heat generated by the CPU.
Some programs are
too draining to run on top of other programs. Try turning off applications when
not in use. You can also try running apps one at a time.
There are times
when your operating system will run background processes without your
knowledge. It doesn’t matter if you’re running Windows 7 or Windows 10.
Fortunately,
there is a way to find out which tasks are overworking your CPU. You can use Task Manager to find your culprit.
Open Task Manager
by pressing CTRL + Shift + Esc. If the window opens in Simple
View, expand by clicking More
Details.
Go to the Processes Tab. Observe the numbers
under the CPU usage column. Arrange
the column to display which programs are consuming the most memory on top.
The CPU
percentage should be nowhere near 100% when in use. Should you find a program
that’s running near that, you can force it to stop working.
Right-click the
name of the application. Click End Task
to stop the program from working.
There are Windows
applications that will stop the computer from working when ended. You will be
shown a warning if you try to stop a vital process.
If
All Else Fails…
Then it just
might be time to replace your fan. It may have degraded to the point where no
amount of cleaning will restore it back to normal.
PC case fans are
not that expensive. A quick search on Amazon showed high-rated selections at
around $10.
Consider
replacing your fans if no amount of cleaning resolves the whirring noise issue.
