Can the two current RDNA-3 flagship models, the Radeon RX 7900 XTX and the Radeon RX 7900 XT, which are equipped with the large graphics processors Navi 31 XTX (355 Watts) and Navi 31 XT (315 Watts), operate without active cooling? ASRock claims they can! However, this statement is only partially true and has sparked some controversy. These graphics cards are not intended for completely passive operation.

The ASRock Radeon RX 7900 XTX Passive 24 GB from the “Passive Series” and its smaller counterpart, the ASRock Radeon RX 7900 XT Passive 20 GB, both feature a second-generation 12VHPWR connection (“12V-2×6”) and are designed for use in server systems with ample airflow provided by large, high-powered fans. Nonetheless, ASRock’s new products are not suitable for passive use in desktop systems due to their high power consumption of 355 watts and 315 watts, respectively.
FanlessTech’s criticism has merit since passively designed graphics cards from professional product lines are not a new concept; the Taiwanese manufacturer is simply applying this established principle to its consumer graphics cards. Aside from the cooling system, which includes a vapor chamber and power supply, there is not much that differentiates these models from the standard offerings.

Can the Radeon RX 7900 XTX and RX 7900 XT Be Passively Cooled? An In-Depth Analysis
Revisiting Passive Cooling in High-Performance GPUs
The advancements in graphics technology have led to the introduction of high-performance graphics cards, such as the AMD Radeon RX 7900 XTX and RX 7900 XT. Recently, ASRock announced that they could offer passively cooled versions of these GPUs: the ASRock Radeon RX 7900 XTX Passive 24GB and its sibling, the ASRock Radeon RX 7900 XT Passive 20GB. However, claims regarding their passive cooling capabilities have sparked debate among enthusiasts and experts alike.
Understanding Passive Cooling for GPUs
What is Passive Cooling?
Passive cooling refers to a setup that dissipates heat from electronic components without relying on active cooling methods, such as fans. This is typically achieved through larger surface areas and materials designed to conduct and radiate heat efficiently. While completely silent operation is desirable in many computing environments, it does come with limitations—especially at higher power consumptions.
ASRock’s Specifications
Key Specifications
| Graphics Card Model | GPU Architecture | TDP (Power Consumption) | Video Memory |
|---|---|---|---|
| ASRock Radeon RX 7900 XTX Passive | Navi 31 XTX | 355 Watts | 24 GB |
| ASRock Radeon RX 7900 XT Passive | Navi 31 XT | 315 Watts | 20 GB |
ASRock emphasizes that these models are designed for server systems with substantial airflow, leveraging large fans to maintain safe operating temperatures. Thus, while these cards might technically be classified as "passive," they are primarily intended for environments vastly different from consumer desktops.
The Debate: Can They Operate Passively?
Thermal Considerations
A major concern with passively cooling the RX 7900 XTX and RX 7900 XT is their high thermal design power (TDP). At 355 watts and 315 watts respectively, these GPUs generate significant heat. The fact that the models from ASRock feature vapor chamber cooling indicates that they still rely on external air circulation to keep temperatures in check during peak loads.
FanlessTech’s critique highlights this disparity, arguing that simply applying passive principles found in professional products to consumer models isn’t a complete solution. Proper cooling solutions for gaming and professional applications require a careful balance of thermal management.
Real-World Usage Scenarios
Given their specifications and design intentions, here are some scenarios to consider:
- Server Systems: In heavily ventilated environments where air is continuously flowing, these GPUs may perform efficiently without active cooling.
- Consumer Desktops: Under typical desktop conditions, attempting passive operation could lead to overheating and reduced performance, countering the advantages of a high-performance GPU.
- Gaming Rigs: Gaming sessions that push the limits of graphics processing will necessitate active cooling solutions to avoid thermal throttling.
Practical Tip: Using ASRock Cards
If you intend to use the ASRock Radeon RX 7900 XTX or XT passively, ensure that your setup includes large cooling systems or optimized air circulation. This will help manage temperatures effectively.
Industry Expert Opinions
Many industry insiders remain skeptical about ASRock’s claims. The consensus is that while the technological capability exists for passive cooling in high-performance graphics, practical implementation requires thoughtful consideration of system design and cooling infrastructure.
-
Cooling Experts: Experts note that the TDP levels of these cards exceed commonly accepted limits for passive operation in consumer-level systems. High-performance GPUs traditionally require some form of active cooling.
- Consumer Feedback: Feedback from users who had attempted passive setups with powerful GPUs indicates that temperature management often becomes a critical bottleneck, leading to system instability or damage over time.
Summary of Key Points
- Operational Environment Matters: These cards may work in server settings with strong airflow; however, they are not suitable for casual or gaming environments without proper cooling.
- Active Cooling Still Required: High TDP demands proper thermal management, and any attempt at passive cooling in a desktop environment could fail spectacularly.
- Market Perception: Confusion in the marketplace could mislead consumers into believing they can operate these cards without fans in standard desktop configurations.
Closing Thoughts
Understanding the nuances of passive vs. active cooling becomes increasingly critical for tech enthusiasts. As the market introduces specialized GPU models designed for various applications, it is essential to critically approach claims around passive cooling capabilities and assess them in real-world scenarios.
While ASRock has made significant strides with its passive cooling claims, the reality for users of the RX 7900 XTX and RX 7900 XT remains: invest in robust cooling solutions to protect your investment and ensure optimal performance.
