Question

Quizplus · Accepted Answer

Opening a computer while it is running is a potential risk for inadvertent damage. WD-40 is not to be used for lubricating computer case fans.
Key Takeaway: Opening a computer case while it is running could inadvertently damage the inside of the machine or risk electrical shock. Never reach inside a computer without taking proper ESD precautions. WD-40 contains alcohol and will destroy the cooling fan. Use very lightweight oil for small equipment.
