The card stays really cool, much cooler than my old lightening 6970. Me posting my own values is worthless because you guys will have different case setups etc.
Regardless, my maximum temps at 1625mv memory, 1200mv Core 1180mh core and 1800mhz memory are 62-3 degrees peaking with powerdraw unlocked with 100% gpu load and 100% fan speed. This is probably pulling something ridiculous like 300w. On BF:3 MAX 100% settings it stays at 59% fan speed, and never goes above 56 degrees Celsius. Just for referance, at my OC I get a minimum of 55 fps and a maximum of 78 fps infantry on a 64 player map on back to karkand (BF:3). In a jet it goes way over 120, but it's normally around 62-5fps during infantry gun battles. In a heli it can dip to 44 fps when I'm being rocket spammed, but it's still playable.
Please not everybody OCing may differ. At idle It's currently at 50 degrees, but right now I'm in 2d clocks which is higher than normal. My case fans are also powered down slightly. On idle (one monitor) clocks, it's at 32 degrees minimum fan speed. Please note I also have a 1080p video playing in my left monitor atm.
I am really happy with this card, and I wish amazon.com would restock it as I plan to purchase two more. If not I'll have to find another website to buy it from. This is also the best TWO SLOT COOLER hands down. Please note the cooler is open, so hot air is dumped into your chassis, with a less airflow-optimized chassis, this'll be bad, and in multi-gpu configurations with this card it will probably cause lots of heat build up.Read more ›
-Best Radeon card yet IMHO, solid GCN architecture, unbeatable computing performance currently (even has 1/4th performance in 64bit computing!).
-Great gaming performance, all you'll need for a long time.
-Cooling is great for single card, or well spaced multi-card setups (personally seen 63-72C range fully loaded, lower in games, depending upon spacing)
-Quiet single card, audible multi-card.
-Overclocks well (1120Mhz stable for weeks in current cooler setup)
-Cooling solution requires separation to work properly, stacking cards together will cause them to suck in hot air from the other card and crash.
-1 of the 4 cards has instabilities which causes it to crash intermittently under full load, the other 3 are perfectly fine.
-Running the cards in a crossfire setup will cause some 'coil whine', this effect is more pronounced in a Quadfire setup and absent in a single card setup.
A couple of thoughts:
-I Do not recommend Quadfire setups for gaming, current games are easily handled by 1 card, and two cards are generally still an overkill. Additionally support for Quadfire setups in gaming is quite absent causing such a setup to give you no advantage in those games.
-I do recommend the 7970 for computing projects (OpenCL), and scales well with more cards if your problems are well defined.
-For those wondering a 1200w PSU was sufficient and stable for Quadfire with a stock-clocked Core i5, 3570K CPU.
I HIGHLY ADVISE YOU PURCHASE YOUR CARD FROM ONE OF THE OTHER MANUFACTURES. GIGABYTES RMA SERVICE IS DESPICABLE!
I won't say that an RMA is a reason to blast a card's rating. It's certainly a very powerful card and crap happens sometimes, but I started to notice digital static in certain overlay modes, especially videos. If I had a video on screen, I would get occasional horizontal lines flickering. Also, I see some unexpected triangles and very brief checkerboards. Not a temp problem, for sure. Extensive testing never ran the card's default settings over 51C. Again, if I were in a remote part of the world, I would make do, but I am taking the opportunity to RMA this card and hopefully get a card better suited for the task. Probably a minor issue with a pipeline. In the meantime, I'm glad I have Intel Integrated Graphics HD4000 on my i5-3570K to fallback to. On the plus side, it confirms the problems were with the card since the issues have disappeared on IIG.
So, a qualified recommendation, but odds are you won't experience the problems I'm having.
UPDATE: After an RMA, this card performs like a dream. The RMA fixed the "static" and a driver update fixed the bad graphics vectors. I'm giving it back it's fifth star. Now, I'm planning on getting a second of these cards for Crossfire. Still, a definite recommendation. I'm rocking my way through Bioshock Infinite now and having a great time.
