NH-D15S Noise Testing

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 407750 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 test (Idle or AIDA64) 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.


NZXT All-New Kraken - Noise Measurement


Overall Results:  Each cooler was darn near silent at idle, and with load put on from AIDA64 while using the CAM software, you barely noticed a change, if at all.  Even when hooked up to the motherboard’s fan header, the noise level was still very minimal.
