Hi Asriel Peters
what case do you have ? what cards and mobo ?
i have had this issue many times , we may be able to come up with a fix , getting air in between the cards is the key

Generally Sli && Crossfire does generate more heat.

Unfortunately there isnt much you can do now, seeing as youve already purchased the motherboard. But next time make sure that the spacing on the motherboard is adequate for your needs.

One workaround that might help :
When people set up their sli and crossfire they generally use the top gpu as their primary
gpu1 -> output
gpu2 -> slave

try using the bottom gpu as your primary
gpu1 -> slave
gpu2 -> output

gpu1 will in turn generate a bit less heat. Well this is what ive realised in builds that i have had.

Also get yourself a SpotCool System Cooler :

Hope i could help.

not even an inch... the old graphics card has suffered some gravitational pull to where the cards were touching ...fan was clicking due to this so i took two pennies and stacked them in between on the plastic molding of the video cards of course ...but i know this is not a great set up

an inch should be lots of room for your top card to breathe and draw in air, i was thinking 2 or 3mm
perhaps the old card got damaged , what motherboard are you using and what cards ?

if you run each card on its own in the first slot to they both reach roughly the same temp ? , perhaps there is dust clagged up in the cards heatsink not allowing proper airflow ?

you may want to look at better airflow into your cards perhaps better cfm case fans ?
I had a friend that mounted a 120mm fan above his sli setup by using two of the unused pci brackets as mounting points for a frame he mounted a 120mm fan on , worked a treat
if you have side panel case fan you might want a better cfm fan for it , what is your case ?

http://www.newegg.com/Product/Product.aspx?Item=N82E168... all fans are running is there a way to mod the fan speed?

not really , the best the fans will run is at 12v 100%
if connected to your motherboard you should be able to change the fan speed to 100% within the bios
or connect the fans to a 12v molex with a molex to 3pin fan connector and run them direct from your psu at 12v
a SpotCool System Cooler fan over the gpu may help as suggested by HolyCowImAnoOb you picked as your best solution
