[Clevo P650RE6] Anormal CPU and GPU noise

Good Night everyone,

First of all I'm sorry if I'm posting this in the wrong forum but it's my first post here.

So, last July I bought a P650RE6 with these specs:
-> i7 6700HQ;
-> nvidia gtx 970m;
-> 16 Gb DDR4;
-> 240 Gb SSD.

In the first days of use, the laptop worked like a charm. Everything runned smoothly, low temps, no anormal noise, everything was ok.
But after a week, I noticed that the laptop was getting some temperatures that weren't normal. So I returned to the store, they saw that the temperatures weren't normal and replaced the thermal paste.

I came back home and everything was fine again.

In the next day, I noticed on a static noise that I could ear when writing an email, moving my mouse, scrolling on facebook, etc. That electrostatic noise some people say that is normal, that is coil whine, but it appeared out of no where and that was really strange to me. Why did on the first days no noise like that exists, but after replacing thermal paste the noise appeared?

So, I couldn't find an answer, and the noise is something like this video (in my case is quieter):


After aproximately 1 month, my laptop started to make another kind of electrical noise, now coming from the motherboard where the AC-DC charger is connected. That noise only happens when the discrete GPU is working, either playing a soft game like Minecraft, or a more demanding one like Overwatch. In any case, the noise is different from program to program. The noise is something like in this video:


So I returned to the store, and we basically took another brand new two P650, and inserted my original DD4 RAM, Wifi connector, keyboard and SSD.
In all of them, they had the same behavior. The only common link between the three, it's the DD4 RAM, Wifi connector, keyboard and SSD.

In the store they say that in other P650 that they build, any of them had this kind of anormal noises. So I can't figure out what it is.

We even tested with 1 DD4 RAM at a time, and noise was still there. But we didn't test the SSD. So can this related to the SSD? Can the SSD be the reason for the CPU and GPU noise? Can the reason be related to another part (like DD4 RAM or wifi connecter or either the laptop keyboard)?

Many thanks for your help, and I'm really sorry if I couldn't be more explicit in my problem.

 

I could be off the mark here, but what you might have been hearing was " coil whine."

 

I highly doubt the SSD is the cause.
Do a couple things and update us:

1. Open up your laptop and spray the crap out of it with a can of compressed air.

2. Make sure all your components are securely connected to where they are supposed to be.

 

Well, this started out of nowhere. And in 3 differente barebones (2 of them being totally new) all of them made the noise.
Tanner thank you so much for your help and reply, I've done both things and is still making the noise.

 

Hi there,

So I returned to the store. Another P650 was assembled with other components and did the same noise. Not with the same loudness of mine but on the same use and application. So I think that both noises are fine. Some computers do more than others.

About the noise near the DC connector, that happens because of the coils that are whining. It appears that is also normal. Or at least it might be.

Thanks for your help

 

I agree, if you can duplicate it on multiple machines and there are no performance problems it's likely normal, if a little annoying.
