question about 6870 crossfire and cooling

post #1 of 6
Thread Starter 
hi everyone,

i just got a second 6870(sapphire with stock cooler), i was wondering if i should upgrade to an aftermarket cooler(gelid icy vision rev. 2). on my first 6870, i have the gelid icy vision installed and it works great!, however, the only thing stopping me from putting on a second gelid on my second card is that my case is a mid tower, so if i do put the aftermarket cooler, it would bump against the psu.

i thought that maybe if i just put my psu outside of the case and cover the hole at the bottom of the case with paper or something to keep dust from coming in.

i was wondering if i should do this, because my psu is a corsair GS700W so i dont know if the cables are long enough if they are out of the case(im pretty sure they are).

has anyone ever had to do this? i was thinking of putting the psu on a a book nex to my pc so that it wouldnt touch the carpet. is this dangerous?

tbh. the second card should not heat up as much provided you do not oc too much.

you can try the second card with stock cooling first xfired, then go from there.

your real problems is bottleneck.

would the bottleneck be the cpu or the vram?

the vram shouldnt be to much of a problem since i dont play at 1080( max res for me is 900), and i usually dont play with all AA, AF, etc. up

as for the cpu, yea, im waiting for the new bulldozer cpu's to come out before i upgrade it
