Technical data / specifications

Regarding the GTX 590 NVIDIA uses two GF 110 GPUs which feature lowered clock speeds. With 165 MHz less on each GPU, compared to a standard GTX 580 single GPU card, this really is a significant change. Such a reduction of clock speeds comes with most dual GPU cards. Manufacturers do this to keep the maximum TDP within a reasonable envelope. A rough calculation shows that decreasing the clock speeds of both GPUs by 165 MHz let's NVIDIA save about 100 Watts of thermal dissipation power. A positive consequence of this measure is that they were able to put a single axial fan onto the card which operates at a resonable noise level. Furthermore NVIDIA put one massive cooling block onto each GPU which provides an efficient heat transport. Unfortunately the axial fan isn't able to blow all the air out of the case which will cause the temperature within your enclosure to rise. Therefore you really should be aware that the card can produce up to 365 Watts of thermal dissipation power and this will heat your case quite significantly. In 2D mode and placed in a closed computer case the cards noise cannot be separated from other coolers within your system but as soon as there is heavy 3D load you'll hear it quite well.
