To conduct our noise level tests, we replaced the graphics card in our system with a AMD Radeon HD 5550 Silence which was passively cooled. We also momentarily disconnected the fans on the CPU cooler so we were only taking into account the noise generated by the fans in the case.
The acoustic performance of this case is quite decent, however it doesn't compare to high-end models like those from Fractal Design.
no air flow is a big turn off
