Hi
I seem to have this strange noise from my headphones and my pc after putting unlimited fps instead of v-sync on certain games (minecraft, fallout 3, unturned) and then when i put it back to v-sync its allright again

Specs:
CPU: intel pentium g3220
gpu: Powercolor r7 250x 1gb ddr6
ram: 1x4 gb ddr3 1600 mhz ram
PSU: OCZ 650W FULLY MODULAR PSU
Case: fbm-02
 


Ah, it seems to be coming from the gpu, also from the HW monitor info from CPUID, the temp seems to increase higher for the gpu to 40 to 60 degrees as compared to the other temps....
 


huh interesting, i disabled my dedicated gpu and when i turn on my headphones (usb) to unlimited fps, the sound stopped but when it turn it back to v-sync it doesn't do the loud sound as usual but it does a quiet and noticable buzzing sound

Now when it comes to the pc it seems to be making a small or barely noticeable buzzing noise as compared to the loud coil whine I described before and it seems to be coming from the motherboard

Edit: Scratch that the buzzing noise has been happening even with the dedicated gpu enabled so yeah its normal
 


The buzzing sound that I believe is coming from my mobo is a very small and barely just barely noticeable sound and I think it has been doing that since I have done my build and that sound is drowned out by the fan sounds and gpu sound (normal non-buzzing sounds) And it isn't hugely loud like the issue i described in my first post....So yeah I think it is my gpu because when I disabled my dedicated gpu, it worked fine well for my pc anyway and when i use my dedicated gpu it does it again....but when it comes to the headphones, there is a small but buzzing sound when i put it on v-sync and when i put it off it works normally?.....I believe that it is the headphones themselves
 


Actually I think the gpu noise it is making is normal since I recently found out that when playing unturned at unlimited fps mode at the main menu, my fps goes over 1000 and therefore causes coil whine on the gpu and when lowering settings on other games that cause it to go over 500 fps like fallout 3 and minecraft
