Recently we have changed our method of measuring noise levels. We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. We are using a heatpipe based passive power supply and an Intel SSD to keep noise levels to a minimum. The motherboard is passively cooled and we use a Sapphire HD5670 Ultimate Edition graphics card which is also passively cooled. Ambient noise in the room is kept as low as possible. We measure from a distance of around 1 meter from the chassis and 4 foot from the ground to mirror a real world situation.
Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.
Today obviously we are testing the NZXT Vulcan chassis, so we have built the system and moved the chassis into our sound room. We measured overall noise with the 200mm fan disabled and then enabled. The room rates as 21dBa – the air conditioning unit in the far corner of the room causes this. We use a Digital Sound Level Noise Decibel Meter Style 2.
KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
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
The final results show that the NZXT Vulcan is generating relatively modest levels of noise, thanks in part to the large 200mm fan which spins at around 1,300 rpm. The noise levels are what we would expect from a high performance gaming chassis and as such are acceptable. This fan significantly improves system airflow and subsequently temperatures, so we feel the increase in noise is an acceptable trade off.
Seems like a nice little product, but its a bit skimpy they didnt include the 200mm fan with it. quite surprised they didnt;
Its a very robotic looking chassis isnt it? quite cool looking, but the removal of the fan, for such a reduction in temperatures seems self defeating.
Good read Steve, interesting looking case, I think its rather fugly mind you. cooling seems good, when you spend another £10 on a fan for it !
Price is good, but they should have upped it slightly to include the 200mm fan, seems like an oversight on NZXT part.
Personally I dont want the 200mm fan, at 39db its too loud for me, id rather opt for a high quality 200mm fan myself online if I needed it.
NZXT are selling in the UK/Europe now I see which is good, as they werent before. I am not sure if this appeals to me really though, its a bit ugly looking.
Looks seem to be splitting opinion here anyway. I rather like it, but its a shame the fan wasnt part of the pricing scheme, for what you get I think its rather costly.
Seems like a rather interesting product but im not sure im sold on the appearance.
Looks ok, I think there are better cases for the money however in todays climate.
I bought one of these a while ago and I can’t say im really that impressed. it is ok, but I wish I had opted for the silverstone SG07 SUGO I read about here last week, its more costly but it looks much nicer imo.
Very interesting indeed, and good review thanks.
Good review Steve – its not my cup of tea mind you, but the review was good.
