Question Crossfire/SLI temperature for the whole case?

[franticc]

I'm just wondering if the temperature of 2 GPUs at 70c and CPU at 75c and other components accumulate. Will the case be really hot? I'm generalizing this, it can be whatever kind of hardware in PC. Thanks in advance.

Generally, more components in operation = more heat.

Can you get 2x GPU in a reasonable temp? Sure.

But the actual question is....why SLI/xfire? That has mostly gone by the wayside.
