I have an evga geforce gtx 760 overclocked 2gig gpu with an intel i5 4670k cpu, asus z87-pro mobo and corsair RM750 psu. My gpu makes a pretty loud buzzing/radiator-like sound when it gets warmed up at times and othet times when under load. If I put support under it or lift up on the cables some it stops but when I let go it will keep doing it. The bracket is tight but I think the modular cables (which are pretty stiff) are putting strain on it. Any suggestions? Temps and fan work fine and I don't thunk it is the acx fan that came with it.
 
Solution
The PCB is the printed circuit board, or simply the circuit board; usually green but can also be black, blue or red. If you are looking at your GPU from this angle:

Stick a piece of foam in between any parts that have a gap like the front SLI ports, the middle part with the PCIe power ports and the back where there is a big angle cut. If it still rattles, try to get a very thin piece in between the very small gaps that are almost touching. Or, try the bottom of the GPU as there are similar gaps there as well. You might also want to check that the mounting bracket is firmly secured to the case's chassis and that power supply mounting bolts are tight as well...
If it is the same thing that happens to my GPU, like a rattling sound, then it is the plastic fan shroud. I took a piece of that black foam/padding that came with the GPU in the box, cut it into a strip that fits in between the fan shroud and the GPU's PCB and stuffed it in that gap. The rattle stopped and my PC is very quiet now.

If it is an electrical buzzing sound then it is probably a capacitor or a component on the PCB and you should send it in for warranty repair.
 
I am not sure what kind of sound it makes. All I know is that when I place some gentle pressure on the gpu or"squeeze" it gently it stops. Sounds more a mechanical issue than electrical/capacitor related to me. Same with my corsair rm750. I figure it should be ok. If I were to do that foam thing, could you walk it through with me how to do that and where to place the foam (ie don't know what PCB stands for...)

Another thing that helped my PC was turning down the GPU's idle fan speed to under 10% using the fan profile modder on MSI Afterburner. You can use Afterburner with any new GPU from Nvidia or AMD. Just make sure you either delete the EVGA tuning app or disable it from starting with Windows and instead start Afterburner with Windows. http://event.msi.com/vga/afterburner/download.htm
 
Solution
I wish I knew what happened with my little piece of foam that came with my gpu. Any suggestions for a substitute? And I am pretty sure it is the fan shroud. If it is buzzing loudly and I place my finger on the gray labek on the fan shroud and press slightly, it stops.
 


Anything that is non-conductive and won't damage the PCB should work. Basically, no metal, glass, wood or hard plastic. Try cardboard or the top of an egg carton. Anything like that. Or, if you have an old mouse pad.
 
You most likely won't need to remove it, just make sure that the PC is off and that the PSU is unplugged and shove whatever you decide to use in the areas where you think the sound is coming from. You don't want to touch the PCB when it is powered on because there is a strong possibility you might short it out or discharge static into something both of which will result in permanent damage and a bricked GPU. It will also keep you from accidentally damaging the fans while they are running. Before you touch anything inside a PC, make sure you touch a piece of bare metal to discharge any static in your hands and after you unplug the PSU, press the power button because it will discharge any power left in the capacitors in the PC. This is all for the safety of you and your expensive PC parts. If you think the noise is coming from something on the bottom of the GPU then you will have to remove it. What I did was before I put my newest rig together, I unbolted the entire fan cover of my GPU and stuck strips of foam all around the inner wall of the fan shroud. It kind of acts like dynamat by simply absorbing the rattles the flimsy hard plastic makes when the fans start spinning faster. Just know that this will probably void the GPU's warranty (sometimes the bolts that you need to remove have little stickers on them). That would also be a good time to clean the fans and maybe even replace the thermal paste on the core.
