I got the idea for this build because I have this nice premounted computer in a piece of plexiglass. I was going to wire and mount a couple more fans next to it and run them off an old phone charger. Then I'm going to hang this thing from the top of my ferm chamber freezer to circulate the air.
Right now I have a desk fan doing that job and it's not exactly the most energy efficient method. Replacing a desk fan with three computer fans has to be a lot cheaper.
Anyway, the center fan has four diodes that light up when it's running. Do I need to worry about them skunking up beer if I decide to use a glass carboy in there? If so I have a couple options for replacing it.
Or I could try snipping the wires to them. But I don't know if they are in series or parallel with the fan motor.
You have to grow up someday, otherwise you become a hipster.
