Size and temperature: smaller=warmer?

[mascip]

Hi all, theoretical question.

I was wondering if smaller motherboard were in general "warmer" than bigger ones.
It would make sense in terms of physics : on a bigger board, there is more surface to dissipate heat, and to let air flow.

Obviously, temperature will also depend on the materials, processor, cooling, case, etc. But for a same processor, cooling, case and all, did you notice that smaller boards would tend to be "warmer" ? Or is the size factor negligible compared to the other factors?

For example, i read that the Asus Z77 Maximus V Gene Intel Z77 would be good for overclocking, while it's only 24.4x24.4 cm2. Is it because it's made out of other materials, or because of some special features ? (like Fan Auto Tuning and Extreme Engine Digi+, for example?)

There are so many different motherboard that you need some (personal) criteria to eliminate most of them, and read carefully the characteristics of the ones remaining.
I was thinking that size could be such a criterion, to find interesting boards.

For me, the methodology could be :
- first, choose a chipset (Z77 for example)
- then, choose a size
- then, other personal criteria

So... what about this size-temperature relashionship ?

The Gene is no better than any other high end Asus board, only it commands a price premium due to it being a ROG board, so Asus pimp it to enthusiasts. The board size itself has little impact on ability to keep things cool, it's the quality of the power circuitry on the board which is largely the same between the boards and the cooling applied, but even then these days things are cooler so it makes next to no odds.

Something (probably obvious to most of you) i just thought about :

a bigger motherboard doesn't mean that the electrical circuits will be less close to each other. It means that you will have more slots (PCIe and others), and space for more features i guess. So, if you don't need these slots or features, it's not necessarily interesting to get a bigger board.

This thread could be closed, i just didn't understand this simple fact.

I'm carefully choosing components and learning, to make my first build, so i will probably have other naive questions to ask
