In the quiet hum of a home PC build, a Reddit user discovered that proximity to power has its consequences — fragments of melted cable insulation clung to the backplate of an Nvidia RTX 5090, a card that draws 575 watts and radiates heat enough to compromise what surrounds it. This small incident joins a growing pattern of thermal damage reports around Nvidia's flagship GPU, reminding builders that the pursuit of performance always carries a physical cost. The machine does not forgive carelessness with space.
