Cooler Master Cosmos II Review

We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.

Today to test the chassis we have taken it into our acoustics room environment and have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the case. The room rates as 21dBa before powering on the system (air conditioning unit in the far corner of the room causes this).

As this can be a little confusing for people, here are various dBa ratings in with real world situations to help describe the various levels.

KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refrigerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum

We have replaced the graphics card with a Sapphire HD5670 Ultimate edition.

A very quiet set of case fans indeed, although we were unfortunately unable to measure variances offered by the built in fan controller, as our early test sample didn't have operational circuitry.

  1. I think that looks awesome, the original was great too

  2. that is one hell of a case, but the weight would put me off. maybe they should have used wheels on it?

  3. I prefer the looks of the storm trooper case, but this is very attractive, I dont think it will be less than £200, even though they tend to be competitively priced cases.

    good job

  4. I almost bought the storm trooper but im glad I waited now for a while, even though I had no option due to spending all my money on christmas presents.

    This looks good and I plan on watercooling this year too, so ideal. the weight doesnt bother me, once its built, it will be sitting in my room.

  5. With a price tag of well over 250Euros (just like the original) i would also put that in the cons……

  6. I hope they’ll release a full tower companion to this..same design just a tad smaller and more affordable

  7. Hi Ted. Quite a few people have mentioned this so im sure they will take it onboard.

  8. Nice review seen it listed in the UK for £330 – guess I will need to get saving!!
