SilenX EFZ-120HA5 Heatsink Review

To test the noise levels generated by the SilenX EFZ-120HA5 we use a Type 2 Digital Sound Level Meter. We place the unit about 1 meter away from our chassis on a 4 foot high tripod to simulate a real world situation.

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
140dBA – Military Jet takeoff/Gunshot (close range)

Our Type 2 Digital Noise level meter does not record audio that registers below 30 dBA.  This means we could not measure the exact noise level of this particular fan. It also means that SilenX have provided a very quiet fan with this EFZ-120HA5 cooler.
