Performance
With three 120mm intakes and a 140mm exhaust, the Noctis 450 shouldn't be short on clean air and the case has no trouble taming our overclocked Core i5-3570K processor.
Only some chassis can prevent our dual GeForce GTX 970s from hitting their 80ºC thermal target. The Noctis 450 just about manages to pull it off, proving that the default configuration should be ample for most high-end builds.
Cooling performance is good but the best bit is that the integrated PWM fan hub keeps noise levels down to comfortable levels. Our test build proved suitably quiet when idle and, with the GPUs able to keep the right side of 80ºC, the system didn't get overly loud when gaming.
