Hi I've got a gigabyte EX58-UD5 motherboard with two Sapphire HD4870 toxic graphic cards. In order to put them both in PCIe x16 slots they are virtually touching. I just tested it playing crysis on all high settings for 15mins then quit and temp of one card was 90degrees- there is no gap above the fan on one card. Question is, should I put one card in the x8 slot which would improve airflow? How will this effect the benefit of crossfire setup? If I continue with current setup will it damage the card? Thanks for reading

i would put it in the 8x slot and it seems you have no other alternative but to do just that

that was a dangerous temperature to be at with NO airflow

try out the 8x slot...the only difference is that it will be using half its potential(just that one card)

Uber :D

Was going to do this but then realised the 8X slot is so close to edge of the board which has various front panel wires connected to it that it doesn't fit because of the fan casing. Looks like best bet is to go with one card and forget Crossfire- not great design, god knows how you're supposed to run a 3 card setup!

You need a bigger case with better air flow... That's the way to runa crossfire or SLI setup and keep temps and reasonable levels.
