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. The motherboard is also passively cooled. This gives us a build with almost completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests.

Ambient noise in the room is around 20-25dBa. We measure from a distance of around 1 meter from the closed 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 video card. It also brings us slightly closer to industry standards, such as DIN 45635.

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

Both cards are very quiet when idle, not registering on our equipment at the rated distance.

When gaming the HIS HD7970 IceQX² Turbo is clearly louder, as both fans are spinning at around 2,200 rpm.

The fan on the HD7950 IceQ however only spins up to 1,600rpm which lowers the noise emissions significantly.

When tasked with Furmark, the HIS HD7970 IceQX² Turbo & HIS HD7950 IceQ fan spin up to 2,500 rpm and 2,100 rpm respectively.
