Topic: GPU positioning (Read 660 times)
I think from the point of view of air circulation and cooling GPU mining rigs make no sense. It's just a ghetto setup using whatever's available. The hardware is designed to fit into an ATX case with it's own air flow.
They are designed for that orientation. The fans on the outside of GPUs blow down towards the board, not up towards the adjacent cards.
My setup has only about 1.25 to 1.5 inches between cards and I have no heat issues whatsoever.
The exhaust comes out the sides of the assembly, like this:

That was an informative image, thanks.
So how come when you put your hand close to the fan you can feel the hot air blowing out of it, adjacent to the cards rather than from it's sides?
ETA: there's probably a way to reverse which way your fan's spinning.... you could probably just reverse the wiring on the fan's power cable, assuming it plugs into a socket on the graphics card. Maybe dangerous.

cca 15cm width of each card, add another 5cm for riser. 5 cards and you got 1m. Than you got problem with length of risers and having long enough wires from psu to cards. Longer wires, more resistance.
You can stack 10 card vertically in 1m, with more than enough space to cool them down.

Why are all GPUs in various mining rigs are positioned vertically with their fans blowing onto one another? Won't it be better if the fans would blow upwards? Or at the very least tilted 45 degrees upwards?
