PC Making some weird scratchy noise.

[KiraGio]

My PC has 6 years already but still working as it should. The problem is, I've been hearing this sound for days and I don't understand why.

Sound: https://clyp.it/cjmgjwfr

I tried changing the fan speed in the BIOS but they do not seem to change.

Thanks.

Edit:
Specs
CPU: i7-3770K
Motherboard: ASUS P8Z77-V DELUXE
Ram: 16GB DDR3 not super sure about MHz
SSD/HDD: Samsung SSD 840, Seagate ST3000DM001 3T, Western Digital WD1002FAEX 1T
GPU: AMD Radeon HD 7970 Sapphire (3GB)
PSU: Cooler Master M2 720W
Chassis: Cooler Master Scout 2
OS: Windows 10

Furthermore, I tried stopping every single fan with my finger and noticed the two GPU fans are not rotating. Don't know what to do.
Thanks again.

You need to isolate the source of that sound. If it's coming from the fans in your case, the GPU, the CPU cooler or the fan inside the PSU. 6 years a good time between your purchase. mind sharing your full system specs like so:

Yea, sorry for even forgetting the specs.

I need to add one thing. This sound always happened everytime I would startup my PC. After 5 minutes it would disappear, like it needed some kind of warming up. Now it doesn't go away and I just hear it 24/7.

Thanks again.

it sounds like failing fan
psu has fan, gpu has fan, case can have few fans, cpu has fan, maybe chipset will have one too
check all your fans one by one (physicaly stop it with hand) until u find that culprit

I have noticed something peculiar doing this. I stopped every single one of them and the sound kept going. But when I reached for the GPU, BOTH of the fans were not moving. Is this normal? I feel like it isn't.

Yea, even if the noise is probably not from it, GPU just doesn't wanna activate the fans even at 80°C. They seem to spin for like 0.5 a second and then stop. Maybe it's normal..?

its not normal, if they spin for half second then they are undervolted

How would I change that? And why would that even happen after years, randomly?

Thanks for your patience.

try with some 3rd party tools like msi afterburner if u can set your fan to 100%
if that doesnt help, u can try to connect fans to external fan controller

Tried MSI but it keeps on saying that the fans are spinning 75% (Even changing to 66 or 100) when they're completely still.
My brains not getting something obvious.

 

[KiraGio]

Is that 0mV related to it or is my GPU just not under load?

 

[KiraGio]

Even so,the noise would still be there...
