ouch, 100c in seconds sounds bad, especially since they have uprated cooling, get the Asus GTX 480 that OcUK stock
And that's with the HAF-X sli cooler with a dedicated fan. I tried swapping the cards and it's the same. On my motherboard there's literally no space between them. I have no idea what the temps will climb to as I switch off kombuster when it reaches 100c. Imagine if I ran furmark :/
The problem now is that I can't imagine another brand of 480 making that much difference in the cards. I've seen people running 3-way SLI without the dedicated sli cooling duct and with a lesser case than a haf-x. I can't understand why the temps are so high. Maybe I'm not going to be able to run SLI? I send an email explaining that I will be returning the cards, but have asked about postage costs as I don't think it's right that I get charged for their incorrect advertising, so I expect them to pay even though the cards are not faulty.
