Noise Level Results
Now that I have tested both the TD03 and this newer TD02, I know the noise levels were not a fluke. With the fans spinning at 1400 RPM with 7.5V running through them, the meter shows a result of 40 dB. Not having the second fan on the back was somewhat helpful, but I wouldn't call 1 dB a miracle or anything.
When we allowed 12V to course through the veins of these beasts, we again see a pretty high sound level at 58 dB. It is not the loudest we have ever tested, but it will definitely get noticed inside of a chassis as the hum makes its way out and to your ears.
