I heard an odd noise coming from my tower. I took the side panel off and had a listen and it sounded almost like a high pitched noise . I checked the fans and they are running normally , but i hear the noise while playing games and i need a solution for my problem .
 

What you're probably hearing is "coil whine" and it happens with some electronic devices. If you have one, take a cardboard tube from a paper towel or toilet paper roll, and see if you can trace where the sound is coming from. Power supplies, motherboards, and video cards can all exhibit this behaviour, but it shouldn't have any effect on your performance.
 

If you can't hear it with the side panel in place, don't worry yourself over it. You can run a 24 hour burn-in with OCSCanner, or just use the card normally and the sound should diminish over time.
