The cellar remains humid, despite efforts to ventilate it better, as described in Ventilatorder:

That is a nice Panasonic 14W ventilator, and built to last. But, not enough.

Bought a bigger one, 46W this time, bigger in size, too, so it runs at a lower RPM, and is not very noisy.

Eat that, humidity!
