Is this coilwhine?

Hi, my graphic card sounds a bit strange. I started a benchmark and I minimized it a few times in the video so you can hear the difference. It can only be heard when under load.

Yep that is indeed coil whine. Hope it's not too loud that it's purely annoying when using the GPU.

I forgot to mention its the MSI gaming x 1080. Can I do something to make it less audible? I read just now that the PSU can cause that problem, but my PSU is brand new (Anter High Current Gamer 750w).
Can I open an RMA for that reason?

It is not so loud now but could it get worse?

Thank you!

It won't get worse, and I highly highly doubt it's your PSU. The only way to make it less audible is to lower your frame rate, typically if you go beyond 120-150fps that's when coil whine begins, but if you keep it below that (use V Sync) that should help reduce the noise.

Thank you very much for your help

Its not the right topic but you may know it: I minimized the benchmark to write the answer here and letters appear very slow when I type. Ram usage is 50% (4gb/8gb), is this normal? Now I shut the benchmark down and its all normal.

Depends, sometimes it happens, sometimes it doesn't. Either way, when the GPU is pegged at 100% sometimes it will make everything else besides the benchmark run slower. I wouldn't worry about it.
