Coolermaster Cosmos S ATX Case Review

Cases & PSU/Cases by jmke @ 2008-03-03

It did not take Coolermaster long to update their high end chassis, the Cosmos S is based on the Cosmos, but made from aluminum, more cooling options, comes with a massive 200mm fan and has a very unique I/O panel. We compare this S(port) version to the original to see how it stacks up.

Test Setup and Test Methodology

Intel Test Setup
CPU	Intel Core 2 E6400 @ 2.8Ghz (from CSMSA)
Cooling	Coolermaster Hyper TX
Mainboard	Intel 975X Bad Axe (Modded by Piotke)
Memory	2 * 1Gb PC6400 OCZ
Other	XFX Geforce 8800 GTX Coolermaster Real Power M520 520W PSU 2x Western Digital 74Gb Raptor SATA HDD

Room temperature was 20°C during testing, ambient noise clocked in at 37.8dBA. Noise measurements were taken at 50cm from the front of the case.

Realtime HDR and Orthos were used to stress the Dual Core system; Core 2 Temp was used to monitor Core temperature (duh) and Speedfan to check the temperature of HDD and Motherboard. Rivatuner’s temp monitor checked the G80 GPU at regular intervals. Maximum values were recorded.

The Intel Bax Axe motherboard features several thermal sensors, the “mobo” values are those recorded by the sensor which can be found between the DDR2 memory banks, marked A in the overview:

Power On

The I/O panel is really the star of the show as you can see in the photo below, the red LEDs illuminate the different I/O headers, and you can also see the HDD activity LED lit up.

Taking a few steps back we notice the red LED fan. The brighter red light comes from our 5.25” fan controller we installed. Each fan in the Cosmos S comes with a 3-pin fan header as well as a 4-pin converter. Hooking them up to the fan controller was a piece of cake.

Great review, thank you for the detailed photos.

Best review I've read of the case... Any idea if they offer extra drive cages separately? They should of at least included a 2nd one for the price...

As much as I am liking this case for how well it fits my needs, the price is a bit to high to swallow. Might at well look at the MountainMod designs, as they start at the same price.

Yes the HDD bay module is available separately from Coolermaster (since Stacker series already), but not all retailers carry this product afaik.

Saw some Cosmos cases at cases with custom paint job, for a nice $900

I've posted this question in other forums, nobody seems to know the answer to it, or does not want to answer. This is my 1st post here, and let me just say madshrimps has the most excellent case reviews I've read, I just like the size comparison charts which gives a very good idea how large the cases being reviewed are!

so here is my question.
Does the biometric power button work like a regular power button when held down. wherein it forces hard shutdown when within windows.

I asked because it just occured to me that it has no reset button, meaning I'd have to flip the switch in my PSU, then I realized my PSU the corsair 520HX does not have a switch. I just wondered what I had to do if my windows locks up.

I'd not like to have to unplug it from the wall.

welcome to the forums!

yes, if you hold your finger on the button it's the same as with a normal power button; as long as you keep your finger on the button it will be in the "on" state and holding it for 4-5 seconds will hard shutdown your system.

Thank you for the best Cosmos S review on the web!

Can you please tell us what fan controller you used on page 5 of the review?

"...The brighter red light comes from our 5.25” fan controller we installed..."

I am a neat freak and as this is a red-light themed case I would like a nice red led fan controller.

this one: http://www.mountainmods.com/sunbeam-...2k8h6oqvnt9t85
Sunbeamtech 5.25" Fan Controller, it's RED because it's feeding the fans less than 7v, at 7v+ the LEDs turn bright BLUE. so do take that into account.
Also the leds are very bright when lit up blue and might be blinding

You can dim them a bit using a method like mentioned here: http://www.madshrimps.be/?action=get...=70&howtoID=29
