first of all thanks on the commet

in the first pic I put a temprature constraint because the floor is on the ground where the temp is prety still, now when i think about it maybe I should change it to condaction

the second pic is for the all other 5 walss in the cube (exept the floor) where I pot the radiation (its in a hot place with direct sinlight) and naglectic wind

in the third pic I add a convection in the ventilator (the ventilator rpresnt as the hole I created), when I add this I get error like in this pic
