Summary
A Taiwanese user reported an Asus ROG Astral RTX 5090 degraded the chipset heatsink coating on an Asus ProArt X870-E Creator WiFi motherboard after about six months of AI workloads.
The damage appeared during maintenance, when discoloration on the motherboard heatsink showed prolonged exposure to extreme heat from the GPU.
The RTX 5090 draws about 700W under full load and can spike to roughly 1,000W, levels experts said can overheat nearby components if case airflow is poorly managed.
The case has revived concerns about high-end GPU thermals, adding to earlier reports of melting 16-pin 12VHPWR power connectors on similar cards.
Experts say buyers of top-tier GPUs may need stronger cooling layouts and 1,200-1,500W power supplies, underscoring rising system-level demands beyond the card itself.
