A forum member at Chiphell has leaked several pictures of  the GeForce GTX 580 reference board, including detailed pictures of the naked heatsink. The blurry pictures of the GTX 580 intact are identical to yesterday's leak.


The reverse side of the PCB is also pictured now, which reveals 8-pin+6-pin power connectors, 2 SLI connectors for 4-way SLI, and 12 memory chips - suggesting a 384-bit and 1.5 GB memory - all as expected. There's no longer holes in the PCB for the fan, but a pretty large bracket is maintained, which suggests a huge chip roughly the size of GF100.


Under the shroud lies a hefty heatsink with no less than 5 copper heatpipes. While the GTX 480 heatsink also features 5 heatpipes, it is slightly shorter in length. Thus, the extra length allows the GTX 580 heatpipes to be spread, and there are no heatpipes sticking out of the shroud, as in the GTX 480. The platform of the heatsink also stays beneath the shroud. The fan seems to be improved as well, with slightly larger diameter and wider blades, than the noisy GTX 480 fan. The shroud's intake area is expanded as well.

There's no doubt, the GF110 is a very hot GPU. However, we can hope that with an improved heatsink and fan, and hopefully slightly lower power consumption, the GTX 580's thermal and acoustic footprints will be significantly improved over the GTX 480's.
