Keezer build question

How important is have a fan in a keezer? I have some reservations about wiring one in. The other question is an effective way to keep inside dry... wireless dehumidifier or desicant or something else? Any information is helpful.

 

A fan is not necessary, but it does help to make sure that there are no temperature gradients in the chest freezer. It is possible that it will be a bit warmer towards the top of the freezer, but its pretty negligible.

I prefer to use a desiccant in them, I have found that a product called DampRid works well and is relatively cheap.

 

for what it is worth, I was worried about the wiring too, so I got one of these fans. the cord is super slim, i just have it drapped over the back of the collar, doesn't let any air get out, and it plugs into any USB adapter plug, like from an old iphone or cell phone charger.

I have a fan running in my keezer and my fermentation chamber. It may help keep condensation down, but I use it to keep the temperature consistent throughout. For humidity, I like this stuff, Dri-Splendor Silica Gel. Put it in a sock or pantyhose, and you can refresh it by drying it out in the oven.

 

Thanks for the advice.
