Really? I've got an A7V266E and haven't noticed anything hot.. and
anyway, I've never heard of a motherboard making a system hot in the
first place. The only things that create significant heat (as far as I
know) are CPU's, video cards, and hard drives -- and none of these
create much heat if you don't tax them. For instance, your hard drive
will only be hot if it is constantly clicking, and the graphics card
will only be hot if you're playing quake. Motherboard chipsets are
extremely lightweight in comparison to these components.
The A7V266E *does* happen to have a motherboard fan on it, but from what
I hear it is just for show and overclockers. There are many other
boards with the exact same chipset which don't come with a fan, so go
figure. Asus always made their boards to be as stable as possible under
overclocking conditions, so I guess that meant adding a cheap fan in
this case.
I don't think that the asus board is creating heat. In any case, it
wouldn't affect the CPU (or the CPU fan) because there's no real way for
the heat to physically transfer like that!

Did you try removing the fan on the motherboard chipset? It's a
worthless, cheap fan, which has been known to be loud.

Pentiums are no longer cooler than Athlons. Athlons used to be hot, but
the new Athlon XP's are just as cool as Pentium 4's. You can go to each
of Intel and AMD's web-site's and read the CPU specifications -- Athlon
XP's and P4's are within a few degrees of each other.
So I think that your regrets about the Asus motherboard and AMD athlon
are likely to have been misplaced. In my experience, these choices have
nothing to do with noise. It has much more to do with the particular
fans you get.
