OcUK Titan 8350a King Cobra MK2 (3.6GHz FX-8120 / 2GB Radeon 7850)

We measured the acoustic output of the entire system when idling and when under the intense load of Prime95's Small FFTs setting and FurMark. As this is a gaming system, we also decided to measure the acoustic output while playing Battlefield 3.

We measure at a distance of 1 metre from the chassis with our digital sound level meter to mirror a real world situation. We allowed the CPU and graphics card coolers to operate at their default settings.

Please refer to our KitGuru noise guide for a comparison between the noise levels of this system and everyday scenarios.

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

Manually set at 100%, the Zalman CNPS 14X fans contribute to the Titan 8350a King Cobra MK2 system's higher-than-average idle noise levels. On the opposite end of the scale, the same level of acoustic output is measured in a gaming scenario which represents very quiet operation. The graphics card fans' increased speed doesn't account for a detectable increase in noise output.

Full load forces the Sapphire Dual-X cooler's pair of fans to raise their speed to a more audible level, increasing the measured acoustic output.
