Gamer Finds Sea of Thermal Paste Under RTX 5090 Cooler
Entity Definition: Gigabyte Aorus RTX 5090 Graphics Card and the Thermal Paste Incident
The Gigabyte Aorus RTX 5090 is a high-end graphics card manufactured by Gigabyte Technology, belonging to the NVIDIA GeForce RTX 50-series category. It is designed to deliver ultra-high frame rates in 4K gaming and accelerate professional workloads such as 3D rendering and AI inference. In a widely reported incident, a gamer who opened the cooler of this card discovered an excessive amount of thermal paste, described as a "sea," covering the GPU die and surrounding PCB components, raising questions about manufacturing quality control.

What Did the Gamer Find Under the Gigabyte Aorus RTX 5090 Cooler?
The gamer discovered a large, uncontrolled application of thermal paste that extended well beyond the GPU die, covering nearby surface-mount components. The paste was described as a "sea" due to its volume and spread. The thermal paste application was so excessive that it covered components beyond the die, raising concerns about electrical conductivity and thermal performance.
"I was shocked to find the entire PCB covered in thermal paste. It was like someone poured it on without any care."

According to the source, the gamer had opened the cooler to inspect the card after noticing higher-than-expected temperatures. The excess paste had oozed out from under the heatsink and hardened in places, suggesting it had been present since the factory assembly.
Why Is Excessive Thermal Paste a Concern for GPU Performance?
Excessive thermal paste can impair heat transfer and pose electrical risks. If the paste is electrically conductive (e.g., containing silver or carbon particles), it can create unintended connections between solder points, leading to short circuits. Even non-conductive pastes, when applied too thickly, act as insulators rather than conductors, trapping heat and raising GPU temperatures. Proper thermal paste application requires a thin, even layer to fill microscopic gaps without spilling over onto sensitive circuitry.
Industry standards recommend a pea-sized dot or a thin spread covering only the die surface. The incident with the Gigabyte Aorus RTX 5090 highlights a deviation from this norm. According to thermal interface material (TIM) guidelines from major paste manufacturers, excess paste can reduce thermal conductivity by up to 15% if the layer thickness exceeds 0.2 mm.
Who Is This Incident Relevant For?
This incident is relevant for PC builders, hardware enthusiasts, and consumers who purchase high-end GPUs and may consider repasting or inspecting the cooler. It underscores the importance of quality control in factory thermal paste application. For users who plan to overclock or maintain their cards, knowing the risks of excessive paste is critical. The case also serves as a cautionary tale for those who open their GPU coolers without understanding warranty implications.
Compared to other reported thermal paste issues (e.g., dry-out on older cards or pump-out on laptops), this is a rare case of over-application from the factory. A 2023 survey by Gamers Nexus found that only 2% of GPU teardowns revealed excessive paste, making this an outlier.
Common Questions
Is it safe to open a GPU cooler to check thermal paste?
Opening a GPU cooler voids the warranty and risks damaging the card. Only experienced users should attempt it, and they must be prepared to replace the thermal paste with a proper application.
Can excessive thermal paste damage a graphics card?
Yes, if the paste is electrically conductive, it can cause short circuits. Even non-conductive paste, if too thick, can insulate the die and lead to thermal throttling or failure.
What should I do if I find excessive thermal paste on my GPU?
If the card is under warranty, contact the manufacturer for a replacement or repair. If out of warranty, carefully clean the paste with isopropyl alcohol and reapply a correct amount.
