80mm fan plugged into NB port

I have an MSI Neo-2 platinum with a P4 3ghz Prescott

It was built for me by a company and I have noticed that an 80mm sunon
intake fan is actually plugged into the NB port on the motherboard (this
board does not have its own NB fan)

There is also only a 300W PSU with 18A on +12V

Does it seem like a good idea to make this fan run directly off the PSU via
a molex-3pin fan adapter?

Also it has a Radeon 9550SE, would a normal 9550 (which I think has a fan)
draw much more power from the board?

Shouldn't make any difference. The fan takes the same amount of power
no matter what you hook it to.
The only thing which could be good or bad depending on how you look at
it is that the NB fan can be controlled by the CPU and it my change
speeds on you. Some might like that because it will make you system
less noisy when it is running slow. The bad is that it may not run at
full speed since the speed of the NB fan depends on the temp of the NB
chip

You can buy an adapter though if you really want to run it of a
connector.
