Acoustic Samples: Listen to this Heatsink!

We were able to take two fan speed sound recordings of the Verax P14Cu. The first was with the Verax fan at its lowest speed setting, and the second with the Verax fan rotation at its fastest speed. As you can see below, at the lowest RPM the fan doesn't even register. At the higher RPM the Verax fan outputs a small amount of noise. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample MP3 file.

Sound Level Measurements:

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. Measurements are made on the dB (A) scale.

Dynatron DY1206BH-625 63.3 dB
Dynatron DC1206BMP 65.1 dB
Thermalright SLK800 66.2 dB
Thermalright AX-7 66.4 dB louder

At a mere 31.2 dB these fans were difficult to measure accurately. Not only is the bottom level on the sound meter officially calibrated for 35dB and up, but even just moving the sound meter around would cause a creek or noise which was louder than the actual fan under power! At full RPM the noise levels rise to 42.6 dB. Up next the thermal results.
