## 问题 **(**The Question**)** ##

SuperUser reader ‘Annonomus Person’ wants to know how to find out which computer fan is being so loud:

超级用户阅读器“ Annonomus Person”想知道如何找出哪个计算机风扇声音很大：

> On my new computer, the fan(s) is/are plain LOUD! Using SpeedFan, I find that my temps are all under 32 degrees C with normal usage (IDK how accurate that is, but the CPU itself says 27 degrees C).
> 
> 在我的新计算机上，风扇很响！ 使用SpeedFan，我发现在正常使用情况下，我的温度都在32摄氏度以下(IDK的精确度是多少，但CPU本身为27摄氏度)。
> 
> The fan doesn’t sound unbalanced, and it isn’t making sounds in a rhythm (not the usual rrrrrrrRRRRRR… rrrrrrrRRRRRR… rrrrrrrRRRRRR… rrrrrrrRRRRRR), it just runs constantly. I am thinking about oiling the fans, but I can’t decide if it is the PSU fan, a case fan, or the CPU fan. If it’s the CPU fan, I will most likely just replace it with a quiet fan. How can I tell which fan is making the noise (if not multiple ones)?
> 
> 风扇不会发出不平衡的声音，也不会发出有节奏的声音(不是通常的rrrrrrrRRRRRR…rrrrrrrRRRRRR…rrrrrrrRRRRRR…rrrrrrrRRRRRR)，它会一直运行。 我正在考虑给风扇加油，但是我无法确定是PSU风扇，机箱风扇还是CPU风扇。 如果是CPU风扇，我很可能会换成安静的风扇。 我怎么知道是哪个风扇发出声音(如果不是多个)？
> 
> One thing that I think may be the problem is my CPU fan isn’t PWM, so would swapping that out help? There is no “linear voltage” or etc. thing in BIOS, so I think it may be running at full speed. Also, there could be too much airflow because it is also making a whistling noise that you can hear when close to it, and sounds like when I accidentally put part of the side cover over my floor vent to get it out of the way.
> 
> 我认为可能是因为我的CPU风扇不是PWM，所以换掉会有帮助吗？ BIOS中没有“线性电压”之类的东西，因此我认为它可能正在全速运行。 另外，可能会有太多的气流，因为它还会发出啸叫声，靠近时您会听到，并且听起来就像是我不小心将侧盖的一部分放到地板通风Kong上以免干扰时一样。

What is the best method for finding out which fan is being loud?

找出哪个风扇响的最佳方法是什么？

## 答案 **(**The Answer**)** ##

SuperUser contributors Hefewe1zen, Darrel Hoffman, and Ross Aiken have the answer for us. First up, Hefewe1zen:

超级用户贡献者Hefewe1zen，Darrel Hoffman和Ross Aiken为我们找到了答案。 首先，Hefewe1zen：

> Use a small piece of plastic (like a pen cap) to stop the fan from spinning. That is the easiest way to isolate the cause. It’s okay to stop it for a few seconds while on. Most fan noise is due to failure of the bearings. Sometimes, lifting the sticker on the hub and oiling it with 3 in 1 lube will help with the noise.
> 
> 使用一小块塑料(例如笔帽)阻止风扇旋转。 这是找出原因的最简单方法。 可以在开机时将其停止几秒钟。 大多数风扇噪音是由于轴承故障引起的。 有时，抬起轮毂上的标签并用3合1的润滑油上油将有助于消除噪音。

Followed by the answer from Darrel Hoffman:

随后是Darrel Hoffman的回答：

> We used to do this on one of our older computers and it worked fine, but a word of warning – while a plastic pen cap is probably okay, **DO NOT** use anything conductive like a paper clip, especially on the power supply fan. A colleague of mine knows this from experience after getting a very nasty shock and tripping all the circuit breakers. He’s lucky he wasn’t killed – there’s supposedly enough charge in a computer power supply to be lethal.
> 
> 我们曾经在一台较旧的计算机上执行此操作，并且运行良好，但要提一个警告-虽然塑料笔帽可能还可以，但**请勿**使用任何回形针之类的导电材料，尤其是在电源风扇上。 我的一位同事在遭受非常讨厌的冲击并使所有断路器跳闸后，从经验中知道了这一点。 他很幸运，他没有被杀-据说计算机电源中有足够的电荷可以致命。

And finally, the answer from Ross Aiken:

最后，罗斯·艾肯的答案是：

> I’ll just put this here as an alternative solution:
> 
> 我将把它作为替代解决方案放在这里：
> 
> Unplug each fan, one-by-one from the motherboard (or from the PSU, depending on the fan), and when you stop hearing the noise, plug them back in one-by-one until you hear it again (to verify that the one you thought was making the noise actually was). I’d do the CPU fan last; everything else will be fine with ambient cooling for an extended period of time. The CPU fan is the one most likely to have issues.
> 
> 从主板上(或从PSU，视风扇而定)一对一地拔出每个风扇的插头，当您停止听到噪音时，将它们一一插回，直到再次听到(确认您以为实际上发出声音的那个是)。 我要最后做CPU风扇； 其他一切都可以在很长一段时间内通过环境冷却来解决。 CPU风扇是最可能出现问题的风扇。
> 
> Granted, if you have a GPU with fans on it, you’ll probably need to use @Hefewe1zen’s method for those.
> 
> 当然，如果您的GPU带有风扇，则可能需要使用@ Hefewe1zen的方法。
> 
> I just don’t like telling people to put hard objects and/or fingers near fast-moving objects. Too high of a chance of someone hurting themselves (especially if they’re un-coordinated).
> 
> 我只是不喜欢告诉别人将坚硬的物体和/或手指放在快速移动的物体附近。 有人伤害自己的机会太大(尤其是如果他们不协调)。

A fan-by-fan approach, with a good measure of caution to avoid a nasty shock or injury, is definitely a good way to learn which fan is being loud.

采取逐个风扇的方法并采取谨慎措施避免讨厌的电击或伤害，绝对是了解哪个风扇响的好方法。
