Cooler Master Cosmos S

System Setup:

With the Cooler Master Cosmos S being a very large chassis, we couldn't help but to load it up with some high-end EATX server hardware. For testing we had installed a Tyan Tempest i5400XT motherboard, dual Intel Xeon E5320 Quad-Core processors, 4GB of DDR2 FB-DIMM RAM, ATI Radeon HD 3870 512MB, Western Digital 160GB Serial ATA 2.0 16MB cache hard drive, Dynatron LGA-771 heatsinks, and a Lite-On SATA DVD 16x burner.

Powering all of this hardware was a Cooler Master Real Power Pro 1000W power supply. This power supply supports Active PFC, 1200 Watt maximum output capacity, ATX 12V v2.2 / SSI EPS 12V v2.91, and is backed by a five-year warranty. The Real Power Pro 1000W has six +12V rails with four 6-pin PCI-E and two 8-pin PCI-E connectors. Cooling this 1000W power supply is a 135mm fan that is designed for ultra-silent operation.

The Tyan Tempest i5400XT is an Extended ATX motherboard, and even so, we had no problems fitting it and all of our hardware into the Cooler Master Cosmos S chassis. It was an absolute breeze working with and installing components into this chassis. Along the way we didn't run into any real issues, but as a word of warning make sure you don't route too many cables behind the motherboard tray otherwise the opposite side panel may not latch completely. Cable management with the Cosmos S was fairly straightforward and easy. When it came to the hard drive area, the cooling for the hard drive area is much better than what could be found on the Cosmos 1000, but at the same time we still would prefer the older drive cage design better or using a different hard-drive mounting setup.

Once installing all of the hardware and powering up the system, the chassis was a bit loud. Most of the noise can be attributed to the two Dynatron LGA-771 heatsink fans, but with the extensive use of mesh in the system, the three 120mm fans, and one 200mm fan, this system had operated louder than when in a different aluminum EATX chassis. It wasn't much louder, but still noticeable. The airflow, however, for this chassis was great as well as the workroom and we have no thermal issues to report.
