Fractal Design Define R6 Tempered Glass Edition Case Review

Benchmark Results & Conclusion

Though we expected higher temperatures from a case with sound deadening insulation and a tempered-glass side panel, temperatures were not as high as anticipated. Thanks in large part to the airflow provided by the dual 140mm intake fans, our budget quad-core i5-7500 processor running at 3.8 GHz peaked at 44°C over the ambient temperature of 25°C. Those of you running highly overclocked systems will no doubt want to take advantage of the water-cooling friendly design of the Define R6 by adding a custom water cooling loop or an all-in-one cooler. On the other hand, GPU temperatures were fairly decent at 55°C over the ambient room temperature.

We took sound level readings with two off-the-shelf dB meters from two different angles. Thanks to the thick sound deadening material and the tempered-glass side panel, the Define R6 registered barely 28dB at idle and 31dB under load. These are some of the best numbers we've seen to date, besting even the be quiet! Dark Base 700.

Determining acoustic efficiency, also referred to as cooling-to-noise ratio, is a matter of averaging all five of our tests to determine a base value.

Added features such as the removable top cooling bracket, a dedicated fill port under the top filter for refilling water loops, and a Nexus+ PWM fan hub will make the Define R6 a favorite with performance enthusiast and water-cooling aficionados alike. The overall construction of this chassis is extremely solid, and the fit and finish are top notch. In the end, you must decide how important those features are and whether they justify the $150 price tag.
