Cooler Master ATCS 840 Aluminium ATX Case
Test Setup & Results
Â
While hardware such as graphics cards and power supplies are always extremely easy to test and the results they produce easily comparable, cases are a different animal all together. You can’t (unfortunately) just install a copy of CaseMark06 on the machine and read back some numbers once it’s done. Therefore, Overclock3D has a standard testing methodology and set of hardware that is used in times like this, so that we can at least get a rough feel for how the case performs.

Today we will be placing the Cooler Master ATCSÂ 840 head-to-head with another similar sized case currently in our labs; the Lian Li v1010. To ensure that we didn’t give either of the cases any unfair advantages only the stock fans were used during the testing. In addition to this, all fans were connected directly to a +12v molex to prevent any potential skew in the results from the motherboard trying to manage the fan speed.
Temperature readings for the CPU were taken using OCCT, GPU via ATITool and System / Hard Disk via digital thermal probe. While we fully understand that the results taken using software appications may not be entirely accurate, they serve only to display the comparitive differences between the two cases when tested under the same conditions.
Â
At idle, the ATCS 840 is already showing its superior cooling performance by keeping each of the components at least 3°C cooler. It is worth mentioning at this point that despite each of the fans inside the 840 running at full speed (12v), the overall noise emmited from the case was lower than that of the V1010 and barely audible above the 4870×2 GPU cooler.

Â
At load, little changes in terms of CPU and GPU temperatures, with the ATCS 840 still keeping things around 3°C cooler. However, while the system temperature inside the V1010 hits 41°C, the ATCS 840 manages to keep everything an impressive 6°C cooler at 35°C.
