LG Fan question

[EAST TEXAROO]

Ok picked up a Lg incubator today For $20 with turner. I have a pc fan 12vdc do I mount it to blow on the eggs or mount it upside down to blow through the vent hole in the top?

It needs to blow down on the eggs. Also make sure you put some spacers between the fan and the foam so it can pull in air.

I have a question...what size computer fan works best? I want to add one, but want to make sure I get the right size/speed. I will need the dimensions...Thanks!

I have 1 that I think will be too big its 4x4 and is 12vdc and it moves alot of air. But fooling around with the space behind the fan will let you adjust the amount of air circulated. I have 2 little pc fans on the way from ebay that I paid $2 total for And I think I am going to use 1 of them. The others are going in my half done mini fridge bator.
