electro/metal scratching sound in CPU area

[dep3kuj]

Hello guys,

I have that kind of a problem, that I am getting some really annoying scratching noice from CPU area. As more intensive graphics I have on my screen the worse souding effects I get. It's not the fans (cuz I stopped each of them manually with my finger).

At the same time I am also getting some crazy HWmonitor results on my CPU package temps. In idle I am getting 75-80, 80-95 C while browsing the internet, and while some gaming like BF4 I get 110-114 C. But the funny thing is that it's not really that hot! I mean when in touch CPU radiator with my fingers while gaming it's just very very warm, but not hot! My GPU is getting around 70-80 C and according to my feelings GPU feels like 2 times hotter (backplate for an example). And while I am typing this text HWmonitor show 71C, but cpu radiator feels almost cool. So I dont really believe it... temp sensor fail?

Every other temps are just fine like it should be, I guess.
Also at the moment I have an open case, extra fan is blowing on my north bridge, everything is getting nice cooling + I've setted every fan in bios to work on full speed.

In bios my CPU shows stable 60-64 C.

Also as an example scrathing\electric sound is getting stronger when I scroll web page with my wheel.

While gaming I also sometimes get micro-freezes (maybe every 20-30 mins) for like 1-2 sec which are happening simultaneously with scratching rhytm.

MoBo is new, got it from service center, where it was checked.  Everything was just fine according to the words of people that work there.

 

specs:

asrock fm2a88x extreme 4+

r9 280

Athlon 860k (stock cooler)

4gb crucial x2

coolermaster 600b v2.0

WD blue 1tb

 

I also was getting some strange jumping cpu frequency with stock bios setting (It was jumping like 2,7ghz to 3,7ghz to 2,9ghz etc) so I've setted power saving feature off, turbo boost off, setted multipl to x40 4GHZ without changing the voltage ( it's 1,3something I guess) and now I am getting stable 3.991 GHZ on my cpuz monitor.

Any ideas? Cuz, to be honest, I am really scared about it...

ur cpu is making dubstep

maybe one of ur cpu fins are cut and is hitting the copper/alumininimium

[Devon_Pearce]

THAT IS WAY TOO HIGH OF TEMPS!

[dep3kuj]

With all respect, do you read what I've written?)
it's not the fans, cuz I stopped each and every one of them manually and the scratching/dubstep sound remains.
And if temp would really be that high then my fingers would be burned by now.

SHUT DOWN YOUR COMPUTER NOW. THAT IS NOT SAFE BORDERLINE DANGEROUS.

Could it be the dust in the cooler heatsink, fans?

 

the temps - if the heatsink feels cool to the touch, make sure it has contact with CPU heatsink, if it still reports those temps, then the sensor is just faulty

[dep3kuj]

No, it's all new from the box, double checked. I've even changed preapplied thermal paste to Spire Thermal grease.

well then it's just a faulty sensor, try returning the cpu

the problem may be with the interface between your cpu and heatsink. do you have any thermal compund you can use for a raplication?

[killtothis]

but cpu radiator feels almost cool. 

Athlon 860k (stock cooler)

 

 

?

I reapplied it 2 times, it's fine. Btw back metal plate plate (on the other side of mobo, behind the cpu) is also just very very warm, considerably hot (but surly not 114C) under heavy load like BF4, consudering it's only passivly cooled by surrounding air.

 

 

?

Ok, stock cooling solution from AMD. That will be more accurate

I didn't realise the Athlons came with an AIO water cooler tbh. If it really was 114c you'd know about it lol

Seems that I messed something here =)

Chill bro. If it was really that hot, the computer would have shut itself off long ago...

 

 

OP: My first guess is Power supply, not CPU. My next one would be Mobo, and then CPU. 

in my life, i've seen ONE cpu fail, ever. 

Take a tube (Paper towel roll, for example) and put it up to your ear. Then move the other end of the tube throughout the machine, putting it next to the CPU, psu, gpu, etc until you find the true source of the sound.

PSU is fine, it's cool and quite. I've already even took it away from the case to listen. No sounds from it (I've located it on the bottom of the case and sound comes from the top where all CPU things are located).

Mobo is fine as the temps tell me. HWmonitor shows temps like this one 

 

I suppose those temps of mobo are OK.

Tried this "tube mode :D", but only thing I can tell, that the sound probably comes somewhere from the cpu bottom line. But I might be wrong.

[dep3kuj]

Btw could this strange sound be from vram module. While digging the web I've found that it could be respnating capasitors or smthing like that?

[dep3kuj]

Update:
So I took all the components from my pc case and made an open stand. As my ears tell me the scratching sound comes from GPU. The GPU itself works just fine, I did not overclock it or something like that. More specificly the sound comes from the area, that is closer to my asrock fm2a88x extreme4+ south bridge.

 

Abot the CPU temps: in bios my systems seems to show the cpu temp correctly, cuz radiator gets very very warm and the number is 63C. 

When looking in windows using HWmonitor it still shows almost 80C in idle and hitting 100C even if I play League of Legends.

So I strongly believe that it's the sensor failure. But who knows...

You mentioned CPU radiator.

[PrimeTek]

lel i doubt any cpu package would last more than 5 mins at 100c+ since its mostly plastic

[dep3kuj]

Update:
So I decided that HWmonitor was showing some seriously wrong staff, so I downloaded my mobo utility and SpeedFan. Tested with prime95 and got these results

 

So as far as I can tell HW monitor is not working properly with my hardware. 
And 66C on 3.5Ghz 100% load with stock cooler isn't bad.

The problem with scratching sound remains. Is it common for a GPU to make these coil whining sound? Because mine is too strong. If PCcase is opened I can hear it from the opposite corner of my room
Should I try to RMA?

Go ahead and attempt an RMA, some manufacturers do accept it for coil whine.

[dep3kuj]

I had a talk today with the shop where I bought my gpu and I've been told that I could try RMA my gpu, but it wont be 100% warranty case. Manufacturer can replace it but it's not certain, cuz gpu itself works fine. Plus I'll have to wait more than a month to actually get any answer. That's really sad, cuz that long waiting drives me crazy more than this coil whine does (just got my mobo RMA a few days ago, waited 40 days...).

So I tried to google to the very depts of the internet for any info.

I've found something. Maybe my psu (which is CM 600b v2.0) has some power saving features that are turned on by default and I need to put it in perfomanse mode. Idk if it is possible. Suggestions?

Next on the list is grounding. As far as I can tell my room has grounding where you plug in the power cable. But who knows, maybe I try some extra grounding?

And the last one is drivers. That is interesting, cuz when I had my OS just installed and had No drivers on my gpu, it was deadly silent. And I dont get any coil whine while I am in bios and I get almost no coil whine when I am just on my desktop. When I start to select some shortcuts or do anything that makes any mivement on the screen - coil whine begins.

My cpu is slightly overclocked (4.0 ghz, want to try 4,2 or 4,5 cuz I just got my new cpu aftermarket heatsink)

[Tedster]

You mentioned CPU radiator.

A heatsink is a radiator. It's mainly designed to take and radiate heat with its larger surface area of mostly highly heat-conductive metal, which is what most radiators do.

For some reason I always think of convective rather than passive when radiators mentioned.

There is no "Fix" for coil whine.

What GPU do you have?
