Noise testing was a highly requested item by our readers, and with this new system, we have those numbers for you!
To obtain our noise numbers, we’re using an Extech 407736 Dual Range Type 2 Sound Lever Meter with the wind screen on. This meter is placed six inches from the top side of the chassis on a level tripod. (See picture) It and the PC case are placed in the exact same spot with the side panel off, as to not taint results, because the movement of just one inch can skew results.
All noise readouts are obtained at the end of the 15-minute test (Idle or Prime95) to allow the system sufficient time to get “settled in.” Ambient noise readout was gathered from only the system fans running, not any component in the cooler.
AMBIENT NOISE: 37.5 dBA
Overall Results: These air coolers were whisper quiet at idle – I couldn’t tell the difference between ambient and system powered on. Looking at the numbers when under full load, they were pretty noisy, but not bad.
