Hi guys. I've recently started folding using a non-OCed Zotac 970 Amp! Omega and I've been experiencing some coil whine on WU 7624 at medium. I have not experienced any coil whine on WU 9201 nor on the games I play. The coil whine goes away when I underclock the GPU to under 900Mhz. Is this something to worry about?
