Computer Buzzing like a bee

[DurbSauce]

So i got a new computer around november 2013. The problem is that when ever i play a game for example like far cry 3, state of decay, bf4, cod ghosts and cs global offensive.... it creates a weird buzzing like bee sound. games like league of legends, dota2, and dishonored dont buzz at all. I recorded it and put it on youtube here is an example http://www.youtube.com/watch?v=4D6bVlgaAYc here is another video with a different game http://www.youtube.com/watch?v=IZFLzQL6WL0. To be honest I don't remember if i had this buzzing in 2013 but it started happening around the beginning of this month. These are my specs none of my parts of overclocked.


intel i5-4670k 3.4ghz
8 gig ram
asus gtx 780
Thermaltake 730w smarts
hyper cooler 212 evo or something.


I have the latest drivers
I have checked my fans at 100% and the sound is not the same as the one in the video. I am quite stumped any help would greatly be appreciated thank you all.

Have you checked the GPU fans and the PSU fans?

Also, is the buzz definitely coming from the tower itself? Or the speakers?

I accidentally clicked best solution. I checked both of those things I am not sure at all where it is coming from. did u see the link i posted http://www.youtube.com/watch?v=4D6bVlgaAYc

Try taking a leaf blower or a pressurized can of air to every square inch of everything in the PC, including fans. It could also just be vibration of something small somewhere. I'm at work, so I can't listen lol

And I unchecked it lol

Well, its probably a GPU or PSU fan.

If you have to, bread board the PC and isolate the sound.

You can either RMA the product once your figure it out, or take your favorite pair of scissors to the part that is rubbing - a little snip might do the job.

It's really odd though that the sound dissapeers after a while of gaming. I'm using a gtx 780 and my temps always reach 78-80(never more) and my fan usage is like 51%. I checked it with a game while it was open to pinpoint the source and i have no idea if i had to guess i feel its like the PSU BOX area. This isn't any sort of coil whine or something though right? It's too different i think for it to be that.

Narrow it down. You can unplug each fan, one-by-one to see if they are the source of the noise. In the case of the GPU fan, carefully press on the center hub of it's fan to stop it.....
