How loud is your Coralife Biocube (29G)?

[Scubafrog]

My Biocube seems really loud with the blue Actinic lights on. At first I thought it was the fans but I'm also thinking it might be the ballast on the blue light. Is it possible for the ballast to make a loud whine/humming sound? There is no noise when the 10K light is on by itself.

In front of the tank I'm getting 55dB and on top I'm getting readings from 65-70db. These readings are with a free phone app so I'm not sure how accurate they are.

I have never seen another Biocube set up so I have nothing to compare the sound level to.

Ya the fans are loud. I was super excited to put a kessil over mine yesterday after using those pc's for a year and a half.
