Corsair Graphite Series 230T Case 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)

Running at 5V the fans are nearly inaudible and fell below the lower limits of our meter.

Increasing the voltage to 12V the fans produced a total of 36.5 dBa. Though audible, we would not classify the fans as loud or intrusive.
