RE: Node '0' Cooling & ventilation

["Paul Gale" <groups@xxxxxxx>]

You'll only get a problem if the temperature of the kit inside Node0 is
significantly colder than the temp of the air entering. This is very
unlikely to be the case as the kit temp will be quite a lot higher (the
whole reason for ventilating).

Paul.

Sorry for being a little behind on the subject, but
isn't there a risk of getting problems with the humidity if you
take air from the outside?

Trying to suck hot air from the top of the cupboard will not work if there
isnt a way for cool air to enter at the bottom of the cupboard.

You need an additional fan to suck air into the bottom of the cupboard.
Ideally both fans need to be ducted to the outside of the house.

You are trying to push hot air into a loft which probably has very little
airflow and in all probability contains air hotter than that you are trying
to push up there.
