Introduction:

What do you want in a new computer case? Do you need a lot of room with a clean looking chassis? Cooler Master has taken the Cosmos 1000 back to the drawing board and ended up with the Cooler Master Cosmos S computer case. The Cosmos S has changed its colors and has made improvements over the old case to improve on its ability to cool the installed components better, which is always a good thing for the consumer. Lets take a look at all of the new features that have been added as well as what Cooler Master has decided to change. Some of these new items are a massive 200mm x 230mm side fan displacing 150 c.f.m. at only 900rpm,instead of the normal push switch, a touch sensitive one is used so there are no moving parts to damage. A redesigned hard drive bay was also added along with quite a bit more. I am very curious to see how the redesigned Cosmos S compares to the Cosmos 1000.

 

Closer Look:

Taking a look at the front of the box of the Cooler Master Cosmos S case, you are able to see the name of the product as well as a little caption saying "Arm yourself with the best." On one of the sides of the case, you are able to see a few products that Cooler Master recommends you put inside of this case as well as a picture of the Cooler Master Cosmos S case with those products installed inside of it. The back of the box is where you are going to find some of the main features of the case, as well as a few pictures to highlight these features. On the other side of the box is where Cooler Master decided to put all of the Cosmos S's specifications listed out, and they again put the "Arm yourself with the best" quote on this side to make you believe you are purchasing the best case on the market.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When you pull the Cooler Master Cosmos S case out of the box, you are able to see the case wrapped in a brown fabric sack as well as protected from the top and bottom by molded Styrofoam. The brown sack is there to protect the case from receiving any scratches during the shipping process, while Cooler Master decided to put the Styrofoam on the top and bottom of the case to protect it from getting bumped and bending parts of the case. When you take the brown sack off, you are able to see that the case is again covered in a plastic bag to keep from any other scratches that could occur. Cooler Master was being very careful when packing the Cosmos S case.

 

 

Lets take a look at the case and see what all there is to it.

The Case:

By taking a look at the side of the Cooler Master Cosmos S computer case, you are able to see that Cooler Master rethought the Cosmos line up and decided to add better cooling solutions to the case. From the outside of the Cosmos S, you are able to see that there is a large fan on the inside and that a majority of the side panel is made with a "breathable" material which will allow the air to flow in easier. On the front of the case, you can see the sleek design that the Cosmos line-up offers, being very simple and not busy at all. At the bottom of the front, you are able to see that there is a fan down there to suck in fresh air from the front. The back side of the Cosmos S case is very similar to the Cosmos 1000, however being black. There is a Cooler Master logo on the upper left hand corner of the side panel. The back of the case is very similar to that of the Cosmos 1000 case, by having the power supply on the bottom of the case.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Speaking of where you mount the power supply on the bottom, you are able to see when you look at the underside of the case that the air intake for the power supply is sucking air in from under the case. right by that there is a spot to mount a 120mm fan that you will suck in fresh air and add more cooler air to the case as well as the other components that you have installed inside. There is a plastic piece that has a fabric air filter to keep most large dust particles from being introduced to the inside of the case which can be removed to clean.

 

 

Taking a look at the top of the case, you are able to see that there are places for 3 120mm fans that can be mounted to blow out the warmer air from the inside of the case, that will pass through the "breathable" top. When you remove the top cover you are able to see that there are the three 120mm fan mounts that you could possibly convert into a place to mount a radiator for a watercooling setup.

 

 

Speaking of adding a watercooling setup, on the back of the Cosmos S case where most other cases have the power supply mounted, is where you will find two pre-drilled holes that have a rubber protector around the sharp edges that you would be able to run some tubing for a watercooling setup.

 

The top front of the case is where the power button and the IO panel is located. However, Cooler Master has done a good job of hiding the IO panel as well as making the power button blend in. The IO panel is hidden behind a sliding door while the power button is a touch sensor button. The power button does not even look like a button, it is more like a small dip in the top of the case.

 

Lets open up the Cooler Master Cosmos S case and see what they have hiding inside and see how much room that there is.

 

 

Closer Look:

Working Components:

Once I pulled the side panels of the Cooler Master Cosmos S computer case, you are able to see exactly how much room is inside of this case, as well as how it is setup. The 5.25" Drive bays all have tool-free features of just pressing a button. The motherboard tray in the Cosmos S is very open and does not have anything blocking it or anything to direct the air. On the reverse side, you are able to see that the bottom of the motherboard tray is very much closed off except for a few holes that will allow the air to flow more freely through out the case and cool the motherboard from under it. These holes will also allow for better wire management.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The side panel that when removed allows you to get to the motherboard tray is very interesting. There is a huge 200 x 230 x 30 mm fan to suck in fresh air and blow it over all of the critical components that you have installed inside the Cosmos S.

 

The cooling system that comes pre-installed with the Cooler Master Cosmos S computer case is 2 120mm fans that are in the top left hand corner of the case. Both of these fans are set up to suck the warmer air from inside of the case out. One is placed on the top of the case while the other is placed on the back of the case. The position of both of these fans are right by where the CPU cooler will be, which should add to more warm air being pulled off the CPU cooler.

 

Now the power supply is at a very unique place, not many other computer cases put the power supply at the bottom of the case and have it suck fresh air from outside the case to cool it, however the Cosmos line up does. The practice of sucking fresh air from under the case could be deadly to the power supply by sucking up large particles of dust and keeping the power supply from functioning properly. Cooler Master has put a fabric air filter that is removable for this exact reason.

 

 

Back to a little more cooling for both the case and some of the components, the hard drive cage. The hard drive cage that comes installed in this case is one that will hold four hard drives. There is a 120mm fan that is pulling in fresh air from the outside of the case to blow over the hard drives to cool them. Then to cool the other components in the case. Not only does this hard drive cage have its own cooler, it also has rubber O-rings around where the screws go onto the case to keep the vibrations of the hard drives from being enhanced by the case.

 

 

 

The connectors that come from the top IO panel are 2 USB, 1 1394, 1 Audio (either HD or AC 97) and 1 eSATA cable. There also is a 24pin motherboard power adapter that has a split from it that goes to the touch sensor button to power the computer, this is so that it will get power directly from the power supply.

 

Now that we know what the case looks like, lets see what the specifications of it are and what the main features Cooler Master wants its customer to know about.

Testing:

To properly test this computer case, I will be testing for both idle temperatures as well as full load temperatures. To test the idle temperatures, I will be letting the computer sit for 30 minutes at idle. To test load, I will run a one hour OCCT stress test with a blend of both CPU and RAM, set at normal priority. I will be using SpeedFan version 4.32 to gather my system chipset, CPU core, and hard drive temperature readings. For the video card temperatures, I will be using ATI Tool version 0.27's built-in temperature monitor. To gather the full load temperatures of the GPU, I will be running 3DMark06 two times, back-to-back, then quickly looking at the temperature reading. All of the temperatures will be read in degrees Celsius.

 

 

 

 

 

 

 

 

 

 

 

 

The Cooler Master Cosmos S computer case did very well when I put it up against the other cases, I was surprised and impressed when the components were able to stay cooler in the Cosmos S than they did in the Thermaltake Armor Extreme Edition. I also was happy to see that the Cosmos S case did better than its previous version as the Cosmos 1000.

 

Conclusion:

Cooler Master has done it again with the Cosmos S case, they have brought a great looking case, with a simplistic design with excellent build quality, to the market that is also able to keep the temperatures down. Cooler Master took a look at the Cosmos 1000 case and improved on it and added the features to make the case better and released it as the Cosmos S case, which worked very well. The temperatures inside the case were significantly lower than the temperatures in the Cosmos 1000 case, while not increasing the noise output from the included fans. The large fan on the side is a great idea and a great feature, however when using the large Thermalright Ultra 120-Extreme CPU cooling solution, you are unable to use the large side fan, as there is not enough room. Even with out the fan being used in the testing, the temperatures were able to stay in a very good range. I like how Cooler Master reworked the hard drive cage in this case and not using the "drawer-style" cage which did not work very well with the Cosmos 1000. I will be using the Cooler Master Cosmos S computer case to house my components, as I was very impressed.
