Test results cooling 400 W
The second set of the four tests we create 400 watts of heat, with fans running on high (12 V). This creates more noise, but also improves cooling performance. Some of the chassis got so warm at 200 W, that we did not perform the 400 W test on them, and some we only tested with the fans on high.

The Nexus Prominent R, Antec Sonata Solo II and Cooler Master Silencio 550 became too warm in this test which forced us to end it prematurely. The remaining five show a clear picture. The Corsair Obsidian 550D survives but is far behind the Performance One P280, and the Cooler Master Silencio 650 gets way too hot with this type of load.

This is the most demanding test, with the fans running on low speed. The Cooler Master Silencio 650 was not able to complete this test, and our heat source had such a negative impact on the sound-dampening material it started to smell quite bad. All remaining chassis more than exceeded 40 degrees, with the Obsidian 550D doing the best. Only the big P280 survived the test properly.
