Fractal Design Arc Mini R2 Review

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. Ambient noise in the room measures close to the limits of our sound meter at 30dBa.

We use the integrated 3-step fan controller to measure noise levels at 5V, 7V and 12V. The CPU and GPU fans are manually disconnected to eliminate unwanted noise.

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 fans produced less noise than the lower limits of our meter at both 5V and 7V. Even at full speed the three fans only produced 35 dBa. Though noticeable we would not classify this as loud or intrusive.
