PC Making revving sound

[Doom]

It seems that whenever i open up any type of program such as the internet or games or other programs i get a very loud revving sound. This also happens at random for no reason it just revs up really loud and nothing is running or nothing has opened without my knowledge. i have tested almost every fan on my PC by either unplugging the fans and opening programs and it still happens as i have turned down my graphics card fans to 10% and up to 100% and the noise stays, if anyone has any clue what it could be or what i should check because i.am.stumped

Actually I just remembed im had the same issue before, it likely to be a motherboard fault, try updating the motherboard or reverting to one of the older versions.

Have you checked you h80i fan?

[ChildOfAtom]

Are you sure its not the hard drive?

[Doom]

i put my head in the case  but i cant seem to be able to find the cause using my ears, i am sure that it isn't a hard drive and i unplugged both the h80i fans when i tried to listen-out the cause yet i still cannot find it D:

I now want to find a sound pack that makes a car revving noise when you open a program. Of course I won't install it on my computer.

[Doom]

ok enough making fun of the way i described it but that is literally the only way i can for that god damn noise

It's either fans or any hard drives or your computer has a combustion engine installed. Unless it's more of an electrical sound then it could be your motherboard, gpu, and possibly cpu?

Power supply fan.Mine does it too.

 

Is it a vroom vroom noise or a squeak squeak noise?

I wouldn't want my HDDs to sound like that.

[ChildOfAtom]

I wouldn't want my HDDs to sound like that.

I wouldnt either, maybe he has 10 velociraptor drives. Or maybe there are 10 velociraptors in there.

It's kind of hard to trouble shoot if you don't know where the noise is coming from.  You could put your ear up a card board tube (empty paper towel roll) and point it at different parts of the computer and try to figure out where the sound is coming from.  Basically it has to be coming from one of the moving parts: fans, power supply fans, hdd, the pump on the h80i, something in an optical drive.
