Regnum 400 ARGB – The most equipped Endorfy case in test

Test methodology

Through gradual evolution and refinement, Endorfy (formerly SilentiumPC) Regnum cases have progressed from the low end to the other side of the spectrum, to the peak. The “400” model with RGB lighting already costs over a hundred euros, but you don’t just pay for attractive visuals. There are up to four fans, three of which are behind a well ventilated mask. But we also came across things that can still be improved.

Test methodology

The case will come with four Stratus 120 PWM ARGB fans. Three are in the front to suck cool air into the case and one in the back to exhaust the warm air. That’s the default setup, the results of which have “(3+1 fan)” in the description, meaning three intake to one exhaust fan. In the second test configuration “(2+2 fan)”, one fan is moved from the front (bottom) to the ceiling of the case.

Testing is done in a home environment where I strive for the most accurate results possible. In the room during testing, the air temperature in front of the case is 23 degrees Celsius and the minimum noise level I can measure with the Voltcraft SL-100 noise meter is 32.4 dBA. The sensor of the noise meter is aligned to the center of the top of the case at a distance of 10 cm, for the best measurement of the speed difference of the fans, which I change using the motherboard. For easy comparison to other cases, they are always regulated to fixed noise levels.

Individual components are heated for 10 minutes in FurMark synthetic stress tests and with Prime95 (custom settings) at the same time. This time is long enough to allow all components to warm up sufficiently. There are then 15-minute cooling breaks between tests, during which the component temperatures (and the case air temperature as well) are brought back to default.

Noise mode levels:

• 36 dBA
• 38 dBA
• 39 dBA
