Soalan tentang produk ini

Will the Sudokoo SK120 PWM fans or the rear 80mm fans need replacement under sustained load?

The chassis includes two front 120mm Sudokoo SK120 PWM fans rated 500-3000 RPM and two rear 80mm fans. All four are pre-installed; fan lifespan depends on operating conditions and dust environment.

Which thermal limit is reached first when all eight 3.5" bays and seven expansion slots are populated?

Maximum CPU cooler height is 117mm with the GPU holder installed or 152mm without it, and GPU length is capped at 270mm. These clearances become the constraining factor before airflow does.

How much noise and heat should I expect from the four included fans running continuously?

Front Sudokoo SK120 PWM fans spin at 500-3000 RPM ±10%; rear 80mm fans run at fixed speed. Acoustic output varies with PWM duty cycle and system load, but the design targets quiet cooling.
