Regnum 400 ARGB – The most equipped Endorfy case in test

Conclusion

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.

Conclusion

With four 120mm Stratus fans combined with an open front panel, the case performed as expected. With cooling performance, it’s on par with cases like the Meshify 2 Compact or Pure Base 500DX. By moving the bottom fan from the front and placing it under the ceiling, you can lower the CPU temperatures a little more, but it may be at the expense of other components.

The design of the case as a whole is well thought out, albeit with some minor flaws. For example, the absence of a USB-C connector, which is being used more and more. Also, a 100-euro case could have used double-threaded screws for the metal side panel. They only come with one and so you have to pull them out, put them down somewhere and they can still get lost somewhere. I also miss the fine nylon filter under the power supply. Especially when you can put two fans on the tunnel, which can suck up fine dust from the ground. But I have to commend them for remembering to offer these positions for the fans on the tunnel. This allows you to fit up to eight 120mm fans in the case. The solid sheet metal used and the free space in the tunnel are also a big advantage – it’s free of storage compartments. These are mounted directly on the structure and thus save space in the tunnel.

The only difficulty in installing the components was managing the cabling. The vertical cable pathway, where most of the cables are routed, is right at the grommets. This doesn’t make organizing them much easier. Additionally, with thicker cables, the rubber caps can come loose and you’ll have to put them back on. Even when I had a larger ball of cables together, I could close the side panel with no problem and the cables didn’t press against it even with worse management.

The Regnum 400 ARGB has its pros and cons. Structurally, it’s designed great, except for the cable management and the missing USB-C connector. If these relatively minor things don’t bother you, the case will reward you with great cooling. For that, he takes home the “Approved” editorial award.
