Yeah I used āno more nailsā tape to mount the stuff, Iād suggest something similar as it is a lot easier than drilling into the fridge.
I got a simple door or gate hinge from the local DIY store to allow the fan to pivot and fold against the wall. I hold it the closed position using a simple bathroom style sliding lock, again from the local DIY store and just lean it against the fermentation bucket when it is running.
Simple and effective
Hereās a photo that shows the fan setup more clearly.
Oh and in terms of wiring it in I used an old 12V adapter for power. I wired the yellow cable on the fan to positive and all the other cables to ground.
I just finished installing it in my fermentation chamber (which happens to double as my kegerator and is placed in my apartmentās kitchen).
That thing is noisy. Itās impossible to live with that level of noise in a kitchen.
What a did: instead of a 12V power supply (the rated voltage of the cooler) I bought another one with 7.5V. Now the cooler spins a little slower but Iām certain itās enough for my mini fridge. And, of course, the noise decreased dramatically. I think I can live with that level of noise (and made the wife happy too).
