Benchmark Results & Conclusion
We tested the Cosmos C700M with our new Intel i9-7900X test platform. For comparison, we brought in the Cougar Panzer EVO RGB, the NZXT H700i and the be quiet! Dark Base 700 to give you a solid idea where this case stands against other cases that are of similar size and feature sets.
Given that this chassis is equipped with three 140mm intake fans feeding a single 140mm exhaust fan, it should come as no surprise that its thermal performance easily bested the rest. At just 57 degrees Celsius under load and 47 degrees Celsius at idle, the C700M is in a league of its own. Even with the fans set to low speed (600 rpm), our overclocked Intel i9-7900X processor running at 4.0GHz peaked at 58 degrees Celsius over the ambient temperature of 25 degrees Celsius, putting it neck-and-neck with the Panzer EVO RGB. GPU temperatures maxed out at 48 degrees Celsius over the ambient room temperature, on par with the other cases we tested against.
For audio testing, we recorded sound level readings with two off-the-shelf dB meters from two different angles. For our first round of testing, we set the case fans to their maximum speed of 1,200 rpm. Our second audio test was run with the case fans on their lowest setting, 600 rpm. The tempered glass side panel and the solid case construction kept sound output to a minimum, even on the highest setting. The C700M generated noise levels on par with the Dark Base 700 and the Panzer EVO RGB. Both of those are also extremely quiet chassis.
Cooling efficiency and noise levels are both ways to measure performance. 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. The results in this graph are a bit skewed due to the C700M’s higher-than-average pricing.
Note that our Performance Value chart above doesn’t take features into account. Even though this chassis has great thermal and acoustic performance, it is hard to justify the $440 price tag based on performance alone. This is where the Cosmos C700M's impressive list of features, unparalleled configurability and unique modular design should be factored into the equation.
Bottom Line
We are the first to admit that this chassis' price tag might be too high for some people's taste, but we also realize that this is a specialized, high-end chassis specifically built for enthusiasts willing to spend their hard earned money to have the best. And make no mistake about it, the Cooler Master Cosmos C700M is one of the best.
