The Cooler Master Cosmos: An Easy-Bake Oven for Your Components
Yesterday, I received my new Cooler Master Cosmos case from NewEgg.com. I spent that evening moving my systemâ€™s components from my old CM Stacker into the Cosmos. It would be an understatement to say that I am very
unhappy with the results.
First, my systemâ€™s components:
CPU: Intel Core 2 Duo E6700, overclocked @ 3.2 GHz, VCore @ 1.28v.
CPU Heatsink: Thermaltake V1.
Motherboard: EVGA 680i SLI.
RAM: Crucial DDR2 800.
Power Supply: PC Power and Cooling 750 watt Silencer.
VGA: EVGA GeForce 8800 Ultra, overclocked GPU @ 660 MHz, RAM @ 2300 MHz.
Soundcard: Creative Sound Blaster X-Fi Platinum Fatal1ty.
Three Maxtor hard drives.
Two Plextor optical drives.
The initial disappointment came with the realization that, when closed, the front door of the Cosmos leaves about 1/8th inch between the front of the drive bay and the back of the door. There is no room for any kind of switches or knobs on the front panel of anything mounted in the drive bays. My Sunbeam reobus fan controller and the X-Fi I/O Drive for my Creative soundcard would have to go. Okay, so I will have to control my fans with the motherboardâ€™s headers. Fortunately, the EVGA 680i has a lot of headers controllable from the BIOS. I could have removed the front door, but then it would look like a dorky case with the door removed.
The second disappointment came when I discovered that the cable management holes located above and below the motherboard tray were completely useless. The smallest wire running out of these holes would block the closing and locking of the caseâ€™s side panel. Therefore, all wiring must be routed through the two cable management holes at the front of the motherboard. [EDIT: I removed my confusing comment here about the wiring and the HDD cage airflow]
The third and final deal-breaking disappointment came when I fired up the system. The Cosmos is a lot
louder and a lot
hotter than my old CM Stacker.
How much louder? The Cosmosâ€™ case fans at 60% are as loud (if not louder) than my Stackerâ€™s fans at 100%. I even replaced the stock fans with my Noctuaâ€™s and the result was the same. The fan woosh from this case is too annoyingly loud for my everyday work at the computer; I work at home as a software engineer.
How much hotter? Can you say Danteâ€™s Inferno hotter? My system, after idling for 30 minutes, with an ambient temperature of 25C (77F), all of the Cosmosâ€™ case fans at 100% and all of the Stackerâ€™s case fans at 50%, the temperatures compared are as follows:
CPU â€“ Stacker: 38C; Cosmos: 45C
. Delta +7C.
VGA â€“ Stacker: 58C; Cosmos: 72C
. Delta +14C!
Hard Drives â€“ Stacker 32C avg; Cosmos: 60C
. Delta +28C!!!!!
Remember, these are the temperatures with everything idling! At full load, the CPU temps were â€“ Stacker: 55C; Cosmos: 65C (Delta +10C). At full load, the VGA temps were - Stacker 83C; Cosmos 90C and climbing (delta +7C+) before I cut it off.
Cooler Masterâ€™s Wind Tunnel fixture for the VGA did nothing to help the air flow to the card.
Moving the 120mm fan from the bottom of the case to the top of the hard drive cage and mounting it as specified by Cooler Master did little to remedy the drive temperatures. It even takes away two of the five drive bays when mounted! The hard drive temps did drop to about 55C, but that is still too damn hot.
To help the airflow, I even put the case up on wood blocks to make sure plenty of air was making it though the bottom air intakes--no improvement there.
If you have any sort of air-cooled, high-end / overclocked components in your system, then just forget about the Cosmos. Of course, if you water cooled everything, then the case would be useable. Otherwise, the Cooler Master Cosmos is an easy-bake oven for your computerâ€™s components!
Itâ€™s time to move my system back into the old ugly, but quiet and cool, CM Stacker. And then issue an RMA request to NewEgg.
The Cooler Master Cosmos gets the coveted SpazzAttack Suck Ass Award.
I hope that your experiences with this case are more satisfactory than mine.
