Wen you hear the name Cooler Master, what comes to mind? Do you think that it's a company that specializes in cooling products? If this is what you thought, you are correct. For as long as I can remember, Cooler Master has been one of the top companies for computer cooling products. Recently, it has unveiled a new computer case called the Cooler Master Cosmos 1000. This case is packed with a bunch of neat features that will impress anyone from a novice to an experienced computer enthusiast. The Cosmos 1000 is marketed with the title "Performance meets Silence", which implies that this case is going to be quiet, while still being able to keep all of the components cool. Let's see how this case holds up against some testing.


Closer Look:

Taking a look at the front of the box, you can see what Cooler Master is marketing the Cosmos 1000 as; a case that is going to be very silent as well as perform just as well as every other case. Soon we will see if Cooler Master has mastered this task. Cooler Master has put the specifications of the Cosmos 1000 on one side of the box and a picture of the front of the case on the opposite side. The rear of the box displays a large picture of the innards of the Cosmos 1000, as well as a few other features they felt were important to display. 













Upon opening the box, you can tell that the Cooler Master Cosmo is packaged very well. It is wrapped in plastic and protected by a Styrofoam mold, keeping the Cosmo 1000 in place and preventing damage from occurring during shipment. 





Closer Look: 

The Case: 

Just by looking at the case, you can tell that it is very sturdy and has a rather modern, simplistic look. The way the case looks, everything seems to just flow together very well. When you open the front door to the case, it will reveal the five available 5.25" drive bay slots, one of which can be converted into a 3.2" bay. Both of the sides of this case are very plain, with no Plexiglass window, nor does it feature a side-mounted fan. The back of the Cosmos 1000 is similar to the back of most cases, however this one has the power supply mounted at the bottom instead of the top. It also features two pre-drilled holes that can be used for feeding tubing for a water cooling setup in and out of the case. 







On the top of this case is where the power and reset switches are located, as well as four external USB 2.0 ports, a single Firewire port, a single eSATA port, and input and output audio jacks. Between the power and reset switches are the HDD indication light and power indication light. 


The bottom of this case is where Cooler Master has put the air intakes for the case as well as for the power supply. There is a 120mm fan mounted towards the front of the case to suck in air and towards the back there is a hole where the power supply can suck in air for its fan. 


Packaged with the case is what Cooler Master calls an "Accessory Carrying Case". Inside is a screwdriver keyring, a bag of screws, 20 cable ties,  and an extended cable for the 8-pin power cable. 



Closer Look: 

Working Components: 

The Cooler Master Cosmos 1000 case comes with four 120mm fans pre-installed inside of the case. Two of these fans are mounted on the top of the case, which will blow the hot air that rises to the top of the case out of the case quickly. There is also a 120mm fan mounted on the rear of the case, above the I/O panel, that also blows more of the hot air out of the case. The placement of these fans seems like a great spot due to the fact that the CPU heatsink will be placed nearby. There is also a fourth fan that is located on the bottom of the case and is sucking cool fresh air into the case, but has its own special housing. The best feature of these fans is the fact that they are silent, operating at an advertised 17 dBA, while still running at 1,200 RPM.






What is so special about the housing that contains the bottom-mounted fan? There is a top piece of the housing that is able to be rotated, allowing you to change the direction the fresh air is being blown. This gives you more control over the airflow in your case; you can point it towards your CPU, GPU, or your hard drives. If for some reason you don't care for this feature, you are able to take this top part off and have it just blow straight up, as seen in the bottom picture. 



The hard drive cage in this case is not like any other that I have seen before. The Cosmos hides the hard drives in little "drawers" that are screwed down.


Behind the front door of the case is where all the 5.25" drive bays are located. The front 5.25" drive bay covers are removable and they are made out of a mesh type material that allows for maximum airflow through the case. This is especially nice for allowing for free air flow in the spots where there is very little fan activity. 



Sound Dampening: 

Another great feature of the Cooler Master Cosmos 1000 is the integrated sound dampening technology. Both of the side panels of this case have a soft textured foam on the inside to keep the sound from being released outside of the case. In combination with the foam, there is a rubber seal around the opening of the main chassis to add to the insulation. 



To make sure that the sides of the case stay on nice and tight and line up with the rubber seal, Cooler Master decided to make the side panels tool-less. They did this by putting a lever on the rear of the case for each side that you pull up to release the side panels. To put them back on, you just apply pressure to the necessary side of the case. Located between these levers are where the pre-drilled holes for the water cooling setup are. 


The sound dampening features do not end there. Cooler Master also put a rubber gasket around the holes in the hard drive "drawers" that reduce the amount of vibration being transfered from the spinning hard drive to the rest of the case, which in some cases can cause a very annoying sound. 


I know that I was excited to put everything in this case because I was wondering how quiet the case was actually going to be, as well as how cool the case was going to be with the radically different fan placement.


I started out by putting the motherboard riser screws in the correct holes and noticed the inside of the case is smooth and very shiny. Unlike most cases, this case does not have the riser screw holes labeled on the actual motherboard tray, which in my opinion makes the tray look nicer. However, Cooler Master included a piece of cardboard that can be placed down on the tray that labels the holes so you know where to put the risers for your style of motherboard. 



Next I began to install the hard drive. Like I had mentioned before, the hard drive rack is unlike any other that I had seen before. To remove the "drawer" that houses the hard drive, you unscrew a thump screw that is above the "drawer" you wish to use and then pull it out. 




Once you have the "drawer" removed you can begin to install the hard drive. To do this, you will need to place the hard drive inside the "drawer" then flip it over and screw it in with the four screws. 




The next step in the installation will be the power supply. This is another first for me; I have always had a case that has the power supply mounted in the top-rear of the case, however this one has it mounted on the bottom. 



The other cool feature about the placement of the power supply is that there is a hole in the bottom of the case below the power supply which allows the power supply to suck in fresh air from the outside of the case, not using up the limited amount of cool air already in the case. There is always the fear of sucking up any dust that is lurking below your case, which Cooler Master already thought about, as they put a filter screen over the hole. 



The installation of the motherboard into the case is the standard way; lining up the screw holes on the motherboard with the motherboard riser screws I previously installed, then tightening down the motherboard with the motherboard screws. 



With all those components installed, the next step would be to install the DVD burner into one of the external 5.25" drive bay slots. Like the side panels of the case, the 5.25" drive bays have tool-less installation features. To install an optical drive, you slide it into the bay and press the button on the side of the bay to lock it into place. 



Once everything is in place and secure, the next logical step would be to plug in all the wires. The Cosmos 1000 offers a lot of places to hide the wires in this large case.



There is also an air flow directer that you are able to place, which helps to direct some of the air coming into the case to the expansion slots.

To properly test this computer case, I will be testing for idle temperatures as well as full load temperatures. To test the idle temperatures, I will be doing this is by letting the computer sit for 30 minutes at idle. To test load, I will then 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 3DMark 05 two times, back-to-back, then quickly looking at the temperature reading.

Testing Setup:


I will be comparing the Cosmos to both the Thermaltake Armour Extreme Edition (containing one rear 120mm fan, one rear 90mm fan, one front 120mm fan, and one top 90mm fan), as well as the Sigma Atlantis (with four 120mm fans; one in the rear, one in the front, and two on the side).  All temperatures are in degrees Celsius.










While the audible sound the case allows to escape is subjective to the person listening, I feel that the case is a lot quieter than both the Sigma Atlantis and the Thermaltake Armour. This is proven by the fact that I can not hear this case outside of my bedroom with the door closed, whereas in the same conditions I was able to hear both the Sigma Atlantis and the Thermaltake Armour.



Cooler Master has brought the greatest aspects of computer cases all together; style, performance, and silence. The Cosmos 1000 is not only a great looking case that has very elegant looks to it, but it also keeps the insides very cool while staying very quiet. Any time that I have taken a look at a "silent" case, I was skeptical about getting it due to the fact that silence often sacrifices some sort of cooling abilities that the case could have offered.  With this case, however, the impact was minimal.

The CPU load testing revealed that the difference between the Thermaltake case and the Cosmos 1000 was basically a wash at one degree Celsius, with the Cosmos 1000 the winner. The other temperature differences were a little greater in comparison with the Thermaltake offering, coming out on top. One issue that reared its ugly head was the hard drive temperatures; a full ten degrees Celsius above the competition. I feel that if some slightly higher CFM fans were added to the Cosmos package it would easily come out on top.

I was also very skeptical about this case's performance when I was installing everything due to the placements of the fans, which surprisingly turn out to work very well. After building quite a few systems I found the rolled and smoothed edges a refreshing change from some of the cheaper cases I have worked on. This led to a bloodless installation of the components, which is always a good thing.

If you are looking for a great looking case that will be able to keep your components cool without being too loud, the Cooler Master Cosmos 1000 is the case for you. When comparing the temperatures of this case with the ones I got with the other cases, and comparing the noise levels, I have a feeling that this will be replacing my current case.
