To the suggestions about taking it back to the store, getting it repaired, etc. That opening it myself would void warranty, etc:
You misunderstood, or maybe my post wasn't clear.

It's working nicely, I just want to reduce the noise level.

I've never opened up my gamecube before but there are several sites that showyou the innards of consoles, I'd imagine the fan is that not that dissimilar to a standard cpu fan.
It's not different at all, I think. You can see it through one of the ventilation grids and it looks just like a standard 70mm fan.
The problem is the screws that hold the thing together.

I don't want to pay for a special screwdriver. It's not really that noisy, just a humming.
I just thought that it'd be fun replacing the humming fan with a more silent one, like a normal 70mm papst, but I got stuck at the special screws...
