Hello and thanks in advance!
I'm a plastics/composites fabricator, and an electronics beginner at best. I'm building a NES system into a thick glass case. I worry about the heat and I don't want to cut a bunch of cooling vents.
I want to add a 5v or 9v cooling fan. Can I just solder the pos lead to the 5v pin on the board, and ground it?
why would you want to add a fan to the nes? O_O

My new case will trap alot of heat, and I don't want to add alot of cooling vents.
The only heat you'll find will be on the voltage regulator/it's heat sink. If you want to do away with heat, get a better regulator which doesn't need a heat sink or get a gigantic fin heatsink. A fan on a NES would be sad, not cool.
Thanks Kyuusaku -- sounds good.
I don't think changing the regulator would really change heat dissipation power, but for sure a single fan would consume a lot more power than the NES itself.
Overloading the regulator with a fan to cool it makes no sense to me. It is like a little cat that want to catch its own tail.
On my NES the 2A03 and PPU also get warm. The main inefficiency is the regulator itself, so you could avoid the issue by bypassing the whole mess and using a modern regulated power supply. There are also more modern regulators that dissipate less power. Finally, you might be able to use the glass case itself as a heat sink by thermally coupling the regulator with it.
