Video card RTX 2070 Super makes a strange sound

Gigabyte video card RTX 2070 Super Gaming 8GB 3X OC rev 1.0
Was playing, suddenly everything freezes, then BSOD, reboot. Now the graphics card is under load (~30%) makes a strange sound like crackling with high frequency or buzzing. Also stress test the video memory used 300MB of 8GB at the same frequency 7000Мгц. I faced anyone? What to do?
