Core Event: Recall and Redesign of ROG Matrix RTX 5090
Asus has initiated a recall of its ROG Matrix RTX 5090 graphics cards due to concerns regarding the application of liquid metal and thermal paste on the GPU core. Reports indicated that the initial application was uneven, leading to potential thermal inefficiencies and risks of leakage, which could damage surrounding components. Popular overclocker Roman 'der8auer' Hartung confirmed these issues through a detailed teardown of the GPU, revealing significant changes in the thermal interface material (TIM) application in the retail versions.
Background & Context: Quality Concerns Prompt Recall
The recall was reportedly triggered by quality concerns, although Asus initially refuted claims of a major defect. Der8auer's investigation highlighted that the liquid metal was previously applied in a ring shape, which, while functional, was not optimal for long-term performance. The revised application method now includes a more professional spread of thermal paste that effectively contains the liquid metal, preventing it from seeping out and ensuring better heat dissipation.
Key Changes in Thermal Application
The new application method features a concentrated area of liquid metal on the GPU Integrated Heat Spreader (IHS), surrounded by a layer of thermal paste. This design includes strategic openings that allow for thermal expansion and prevent leakage. Der8auer noted that this change not only improves thermal performance but also enhances the overall reliability of the GPU under load conditions.
Performance Improvements
Testing conducted by Der8auer indicated that the revised ROG Matrix RTX 5090 GPU now pulls nearly 800W during stress tests, with temperatures stabilizing around 70-72°C under full load. This marks a slight improvement over previous models, which operated at slightly lower temperatures but with higher power consumption. The new design aims to ensure that the GPU operates more efficiently, particularly under demanding conditions.
Official Statements & Responses
Asus has acknowledged the recall as a necessary step to enhance product quality, emphasizing that the changes made were in response to user feedback regarding thermal performance. The company has committed to ensuring that the retail versions of the ROG Matrix RTX 5090 meet high standards of reliability and performance.
Criticism & Opposition
While the recall has been viewed positively by some as a proactive measure, critics argue that the need for such a significant redesign raises questions about Asus' quality control processes. The initial application of liquid metal, described as a "manual hack job," has led to skepticism regarding the manufacturing practices employed for such a high-end product.
Verbatim Quotes
- “(Image credit: der8auer on YouTube) As you can see above, the liquid metal now essentially hugs the thermal paste on the substrate, with two more lanes of it blocking the metal from ever coming out.” — Roman 'der8auer' Hartung, Overclocker
- “The modder also appreciated the fact that these GPUs were recalled to fix a complaint; a costly effort, but one that's probably expected when $4,000 is on the line.” — Roman 'der8auer' Hartung, Overclocker
- “This isn't a direct comparison, but overall, the GPU now seems to be performing slightly better thermally.” — Wccftech Analysis
What's Next: Future Developments
Asus is expected to continue monitoring the performance of the revised ROG Matrix RTX 5090 GPUs and may implement further adjustments based on user feedback and performance data. The company aims to restore consumer confidence in its flagship graphics card offerings.
