The well-known repair channel NorthridgeFix shared a video card repair video. In order to pursue the ultimate cooling, a player replaced the original silicone grease of his ASUS TUF GeForce RTX 5070 with liquid gold cooling.Due to improper operation and lack of protection, liquid gold overflowed on a large scale in the small PCB space, eventually causing this valuable graphics card to be completely scrapped.
The original factory of this graphics card was not equipped with liquid gold heat dissipation. Users purchased thermal conductive materials to modify it. From the maintenance video, it can be seen that the liquid gold has overflowed from the core area of the GPU, spread to every corner of the PCB, and even penetrated into the bottom of the core.
Since the RTX 5070 is not designed for liquid gold heat dissipation, the overflowing liquid gold quickly spreads like mercury to tiny components such as capacitors around the core, forming a micro-bridge short circuit.
Under the microscope, the GPU core had physical edge cracks due to the infiltration of liquid gold, and the internal short circuit was scrapped; the memory module also suffered; the 1.8V power rail was short-circuited to ground, which meant that the liquid gold touched the ground pad and destroyed key circuits.
NorthridgeFix announced in the middle of the cleanup that "only a miracle can save this graphics card".Even if a core is not directly contaminated, a short circuit in the power rail can be enough to completely destroy it.
Afterwards, the user tried to apply for warranty from ASUS, but was decisively rejected by the official due to "physical damage, inconsistent serial numbers and human tampering."
