Cooler Master Hyper 103 Review

To measure noise levels we place our sound level meter approximately 1 meter away from the chassis and 4 feet off the ground.

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

Under normal PWM conditions the fan's noise levels fell below our meter's lower limits. Running at full speed we recorded 38.4 dBa … noticeable but not frustratingly loud.
