Acoustic Samples: Listen to this Heatsink!

The waveform image we captured tells most of the story, making the need to actually listen to the MP3 pretty much mute. The Verax fans are indeed very very quiet. Still, if you would like to hear just how quiet, then click on the headphones and listen to the MP3 recording.

Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take Decibel readings with a sound level meter. These results may be higher than the manufacturer's listed specs, but then again these are real world measurements.

The Verax P16 is the first heatsink we have seen able to come in with a lower acoustic measurement then the Zalman coolers (which offer a better thermal performance, and a bit more noise). With the powersupply on silent mode you still have to put your ear to these heatsinks to hear them.
