Just got a HIS 6970 with a complete new system. It starts to emitt a very high pitch whine in graphic intensive encounters thers no performance decrease or smell just the whine. Did a quick google search and found that alot of people are reporting it. Some cards have it some dont they say. I guess its not a problem?

I was about to post that mine do it too, but I just checked with the side panel off in 3dMark11 and Furmark and there doesn't seem to be any whine anymore. Mine was never loud enough though that i could hear it with the case closed and it was mainly there when the cards were heavily overclocked.

yeah, my 4870X2 does it as well. its a bit annoying, but Ive never had a problem with the card (except heating issues). If i were you Id just live with it. Play your gams with headphones on and i doubt you'd hear it.

Thats capacitor squeal, you will get used to it, its an ATI thing. Some Intel CPU's do it to with C1E and EIST on when in idle.

had it with my 8800gt and 4870x2 not real noticeable most the time at stock clocks but got much louder with overclocking enabling vsync often helped make it quieter

you reminded me of my 8800gt dasa, it was probably the worst for squeal out of any card I have used.

yer mine was fairly good at stock clocks 650mhz in most games but dam did she squeel when benching at 890mhz with a heap of extra juice :)
truble was it was also rather loud in some games at the 24\7 oc whatever that was... somewhere around 850mhz i think

Yeah I get something like that too, though its not really a squeal just a faint noise you hear it make when under load. Though I have to have watercooling to hear it as the stock fan would drown it out. (5970 I'm talking about) I always thought it was the VRMs switching faster to give the higher Amps/volts, thus producing an audible "hiss" or whatever.

I used to get it with my 8800GT too. And my HD5870. I only really get it on S.T.A.L.K.E.R's main menu. I don't recall it happening any other time.

After putting water cooling on my card over the weekend I can report mine does not give off the hiss that the HD5970 did under load. But then again they used different (beefier?) voltage regulators I think on this thing.

And here I was thinking my ears were becoming sensitive. I have it on my 5850, not that annoying though. I just pulled the damn thing apart a couple of days ago, gave it a clean and whacked some Arctic Silver 5 on the chip. I can still hear it but not as much, temps are down which is good but I'm still going to keep an eye on it. Had to clean my K62 as well. *sigh*
