Things You'll Need
Instructions
Use a vacuum cleaner, set to low power with a dusting nozzle attached, to clean out the ventilation ports on the back and sides of the system. If you don't have a dusting nozzle for your Wii, a new dry toothbrush can also be used.
Place the Wii in a dry, dust-free environment free from direct sunlight. Don't put the system deep in an electronics cabinet or directly on carpet. Such operating conditions can cause the machine to suck dust, which clogs the cooling mechanisms, leading to overheating.
Ensure the console's vents have free space to take in and expel air. The vents, located on the back and sides of the machine, should be given at least an inch of free space for effective air flow. Don't cram the Wii between games, DVDs or other electronics: The machine needs room to breathe.
