Cooler Master Cosmos S Case

Testing & Results

While stuff like 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.
CPU: Intel Core2Quad Q6600 @ 3.2ghz (1.45v - toasty)
Graphics Card: Sapphire Ultimate X1950 Pro
Motherboard: Asus P5K3 Deluxe (stock heatpipe cooling - even more toasty)
Hard Drive: 1x Hitachi Deskstar 80GB 7K80 SATA2 7200RPM
CPU Heatsink: Stock Intel (burning hott!!)
Installation Results
Cases can be fiddly little buggers, so naturally the first test for the Cosmos S case was to see if we encountered any problems getting the hardware listed above in position.
Cooler Master Cosmos S Inside Cooler Master Cosmos S Inside
OK, so it's a bit of a mess in there, but I'm pleased to say that installing hardware inside the Cosmos S was a total breeze. Finding the correct screw holes to place the motherboard stand-off's was especially easy thanks to Cooler Master's card sheet (pictured right), which assigns each of the screw holes a letter and provides a corresponding chart for ATX / E-ATX motherboards.
Temperature Results
To ensure that we didn't give the Cosmos S any unfair advantages, only the stock fans provided with the case 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 and Case were taken using Asus' PC Probe, GPU was taken using ATITool and Hard Disk directly from S.M.A.R.T. While we fully understand that these results may not be entirely accurate when compared with a digital thermal probe, they serve perfectly well when results conducted with the same core hardware.
 Cooler Master Cosmos S Idle Temps
Idle temperatures were taken after 30 minutes of the machine being....idle. Ambient temperature outside the case at this point was 22 °C
Cooler Master Cosmos S Load
To get the system hot under the collar, both OCCT, ATITool (artifact scan) and HDTach (Long Bench) were run simultaneously for 30 minutes. As we can see from the graph above, the temperature inside the case rose by a total of 11c, which isn't too bad considering components such as the CPU and GPU were kicking out between 50-60°C of heat. In comparison, a recent test of Lian Li's V2000 chassis (under same conditions) saw a slightly larger increase of 15c. Good work Cooler Master.
Noise Opinions
The 120mm and 200mm fans that Cooler Master has included in the Cosmos S are extremely quiet to say the least. With the PC at idle all that can be heard is the gentle whisper of air out of the rear of the case. In fact, under load conditions the noise of Cooler Master's fans was totally drowned out by the stock Intel heatsink fan and graphics card fan.

now that looks like a nice case...

especially for watercoolers

i'm guessing if you wanted to, if not watercooling, you could have 3 120 mil fans just on the top of the case, blowing hot air out, which would work like convection Quote

Mr. Smith
It's ok; too much plastic (any plastic on a case is too much) and doesnt accept thermochill rads :/Quote

Yeah problem with thermochill rads is if you design a case to take one, it wont take anything else...and the global distribution of thermochill pretty much sucksQuote

Just a little heads up, the last page on the page selector is called "double click to edit"..

I havent had a chance to read through it all, this may be explained but whats the 24pin for?Quote

Oops so it is, changed

Case looks nice, fantastic to be a 360mm RAD readyQuote
