Redditor uses ’ticking time bomb’ vial of gallium to stop their GPU sagging
A Reddit user has shared an unconventional solution to GPU sagging: using a vial of gallium as a physical support. The Redditor, Philip_777, described the makeshift anti-sagging intervention as both a “temperature indicator and ticking time bomb,” acknowledging the inherent risks of the approach.
Gallium’s extremely low melting point—around 29.76°C (85.5°F)—makes it particularly hazardous for use inside computer hardware. At typical room temperatures or with even moderate heat generation from PC components, the gallium could liquefy, potentially causing damage to sensitive circuitry. The user appears to have chosen gallium primarily because it was one of the few objects that matched the precise height needed to prevent the GPU from sagging under its own weight.
GPU sagging is a common issue in high-end graphics cards, where the weight of the hardware causes the card to bend slightly over time, potentially stressing connectors and affecting performance. While various commercial solutions exist—including specialized GPU supports, anti-sag brackets, and mounting solutions—this Redditor opted for a creative but notably risky alternative. The post has generated discussion around PC building practices and the importance of proper hardware support.
