Benchmark: GPU temperature
The Carbide 300R's front 140mm intake has a direct path to our Radeon HD 6970 graphics card, and it provides good performance at this price point.
Of course, for serious gaming builds, there's an option to add another front intake as well as two side intakes. Four 140mm fans should be enough to cool any CrossFire or SLI configuration, but as we're about to discover, noise will be an issue.
