25w is way too much, use 15w max.
also you should go for a wire install if its your first time installing in a wii.
the wattage on a solder iron has nothing to do with anything (as long as you know what you're doing). my weller rework station is 80w and works wonders. I've done at least 20 installs without any issues (in fact, once the systems are opened, soldering only takes about 2 mins and you're done).
I have no idea what people are doing to fry the points on the motherboard like I've seen (and fixed) unless they're laying the iron down and then walking away for a bit.
to gth44331:
definately open up your system to see what you're getting yourself into. practicing on old soundcards and such is a good start, but may not prepare you for how small the soldering points actually are. to give an example, for the systems where the pins have been cut, you need to rebuild 3 lines in the space of just over a millimeter.
