14 DAY TRIAL // After Nvidia released a new BIOS to deal with all the overheating problems that seemed to affect the GTX 590, most of us though that all these issues were resolved, but a recent report comes to reveal that this isn't actually the case as the GTX 590 was measured reaching a whopping 111.9 degrees Celsius in a pretty standard thermal test.
This value was registered using an infrared thermal imaging camera that was directed at the back of the card's PCB.
As the French Hardware.fr website has come to find out, the printed circuit board spot that reached 111.9 degrees Celsius corresponds with the placement of the VRM chips.
This is by no means surprising, as these were blamed by most for the problems encountered by Nvidia with the GTX 590.
All the results were recorded with the system installed inside an Antec Sonata case with a relatively poor air circulation which pretty much mimics most gaming systems out there. The tests were run with the GTX 590 at its default frequencies and operating voltages.
To see how Nvidia's opposition fares, an AMD Radeon HD 6990 dual-GPU graphics card was also put through the same tests and AMD's solution reached 90.3 degrees when the stock clocks of the card were used.
This time, the highest temperature was recorded near one of the two Cayman XT GPUs installed.
With the card run in the AUSUM mode, which raises its TDP 75W over that of the GTX 590, the maximum measured temperature reached 96.1 degrees Celsius. This was also recorded near one of the two GPUs.
The GeForce GTX 590 is Nvidia's flagship graphics card and it packs dual GF110 GPUs installed on the same printed circuit board and linked together in SLI.
As a result, the card features no less than 1024 CUDA cores, 128 texturing units, 64 ROP units and dual independent 384-bit memory buses which connect to 3GB of video buffer. (via Nordic Hardware)
