MSI GTX460 HAWK Talon Attack Vs Powercolor HD5770 CrossFireX

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 also passively cooled. This gives us a build with 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 dBa. 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 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

The MSI Talon Attack has been designed to deliver ultimate cooling performance and as such the noise levels are a little higher than several of the GTX460’s we have tested before – the fans are set to higher than normal rpm. It isn’t that noticeable until overclocked and loaded with Furmark.

The PowerColor HD 5770’s can be easily heard when gaming, even in a modest enthusiast system as they generate over 41dBa. When running Furmark this rises to 46.5dBa. They run cooler than the XFX HD 5770’s single slot cards we tested in August but the downside is much higher noise levels.
