When i try create a simulation i get the “there are no contatcs” error. The thing is im not sure of what i should contrain on my CAD drawing. Please kindly advise if you have the time.

Nice model Enzo!
What I would maybe suggest is to use the Conjugate Heat Transfer analysis which can be used for electronic enclosures. A nice feature that you can use to make sure contacts are detected is the so called Imprint CAD preparation feature (assuming your surfaces touch).
Maybe two more tips:
Use a momentum source if you want to get rid of your fans, otherwise you should enclose the turning fan in a cylinder and use the so called MRF approach
Defeature your geometry as much as possible, the details of your casing is most likely not contribute very much to your internal heat transfer
Hope that helps - maybe the @cfd_squad wants to add their two cents here.
