The fan is a bit loud, but it seems to work correctly, so I don't plan to touch it.

However, the GC has a CR2032 battery to save the time and a few settings, and that battery was dead. But in Nintendo's infinite wisdom, the battery is soldered, not socketed, and the space around it is quite tight so a normal socket will not fit. Removing it and soldering a battery socket was quite a chore, I needed to try different models until I found one that fits, but in the end I managed to do it. When the new battery dies in 10~20 years it will be much easier to replace it.
