White flickering dots caused by fan speed increase (6950)

Hi,

I recently purchased a 6950 2GB HIS IceQ. I got flickering white dots on one my screens after gaming for some reason, so thinking it might be the screen, I got another one and tried it on there, same thing. After I thought it might be the VGA cable, switched it for a DVI, same problem.

After gaming I always turn my fan speed up on my card to decrease the heat, when I turned the fan back to normal the flickering white dots stopped. If I turn the fan back on I can get it to flicker again. The wierd thing now is that the flickering dots don't happen on the same screen anymore, so I had a feeling it had something to do with the last screen plugged in.

I unplugged one of my 4 screens, cranked the fan speed up to 100% and nothing, no flickering what so ever on any of the 3 screens.

So, what's next? Driver problem or card problem? I bought the card 9/8/2011 so I can still get a refund/replacement and get something else.

Your suggestions are appreciated.

This thing overclocked?

Factory OC, yes. 880/1300

edit: Oops, I just realized it's at 900/1325 from when I was testing stuff out. Do you think I should revert the settings? I didn't come across any issues in games other than this flickering thing on my desktop.

I just reverted the settings and it does it far less but it's still there. If you can, could you explain to me why this is relevant to the GPU and memory clock and I might be pushing it here, but why I had this issue on another screen and now it changed to the last screen I plugged in the card?

edit: Thanks for the pointer BTW.

Well, usually when i had issues with my card, it had to do with one of two things, my card was getting too hot, or the overclocked settings were to high,(unstable overclock) but I find it interesting that it still does it on the factory overclocked settings.
 
Yeah, what's even more weird is that it doesn't do it with 3 screens plugged in, but it does it with 4, and it does it on the screen identified as #1 in the screen resolution settings. Because the monitor that used to do it doesn't do it anymore, and the new #1 monitor does it.

But what does the fan increase have to do with it flickering though? Because the card isn't hot at all when I filmed the video, you can see it's like 45c.
 
I have no idea on that one.
so it only happens when the fan is all the way cranked up?
 
Well I can get it to do it on command if I crank the fan up. Today it started doing it with the fan only at 65%. I think I'm going to get an exchange on the card or possibly a refund and get an NVIDIA or something.

The only issue is that I have 4 monitors and Eyefinity let's me put everything on one card so I'm pretty much stuck with AMD if I don't want to spend for 2x cards.
