3x 7970 Crossfire FPS drop out - Page 2

post #11 of 15
Yeah, that should typically deliver the better results, because you're making the path of cooler air shorter to the cards.

So the side panel case doors had two fans that were blowing air out...so I turned them to blow on the graphics cards and added two more to the panel as well. Things are way more stable now. Temps are down to around 90-93 and the throttling as stopped.

But, I definitely can see the Frame Pacing issue now. In BF4 I'll be getting 80fps and it'll feel like 25-30 every now and then. Now full on stutter, but when sniping you can tell some frames are missing.

With just two cards, it looks as if AMD has the pacing thing fixed. They just need to get on the fix for 3+ cards.

Are those 7970 reference coolers or aftermarket?

Generally, you want more air coming in than going out. This maintains positive pressure inside the case and helps keep out dust.

They're reference coolers.
