Not only that, but if I hit that magical mid to high 20s in the cupboard then humidity might very well sort itself out too..
So my question now is, what do I need to know about speed controllers, and do they work on any fan with a single switched input?
I don't want to buy an overkill fan if I can't slow down the flow rate.
