Ryzen 7600X's Temperature and Cooling Solutions
This review addresses the concerns surrounding the operating temperatures of AMD's Zen 4 CPUs, particularly the Ryzen 7600X. With temperatures typically reaching around 95C, there's debate over whether using less than a liquid cooler would result in performance loss. We explore this by testing the 7600X with various coolers, including AMD's Wraith Spire box cooler.
Testing the Ryzen 7600X with Different Coolers
Initial Tests with Liquid Cooling
In our initial review of the 7600X, we used the be quiet! Pure Loop 2 FX 360mm liquid cooler, where the CPU still peaked at 93C under an all-core workload. This high temperature led to assumptions that air cooling might result in thermal throttling.

Experiment with Wraith Spire Box Cooler
Contrary to expectations, testing the 7600X with AMD's Wraith Spire box cooler yielded surprising results. Despite being an older, less advanced cooler, the Wraith Spire managed to handle the 7600X's heat output more effectively than anticipated.
Exploring Eco Mode and PBO2 Curve Optimizer
Understanding Eco Mode
AMD's Eco Mode limits the 7600X's power to 65 watts, a 24% reduction from its full power capability. This mode aims to reduce thermal output with only a slight impact on performance.
PBO2 Curve Optimizer with Negative Voltage
The PBO2 curve optimizer allows for adaptive voltage and frequency scaling. For Zen 4 CPUs, reducing voltage is key to managing thermals, as these CPUs are thermally limited. However, undervolting can introduce stability issues, and the degree of successful undervolting may vary between individual chips.
Benchmark Results and Performance Analysis
Benchmarking Approach
We conducted extensive testing with the Ryzen 7 7800X3D CPU, using both the Wraith Spire and a 360mm liquid cooler. The benchmarks covered a range of scenarios, including gaming and stress tests, at various resolutions.
Cyberpunk 2077 and Gaming Performance
In "Cyberpunk 2077" without ray tracing, the 7600X showed a 22% performance drop at 1080p with the Wraith Spire compared to the liquid cooler. Ray tracing tests further emphasized the GPU's limitations under different cooling setups.
Multiplayer Gaming with Eco Mode
For multiplayer games, the 7600X in Eco Mode proved to be a viable option, offering sufficient performance with reduced thermal output. The VRAM capacity was less of a concern in these settings.
Stability Challenges with PBO2 Undervolting
While initial tests with negative voltage offsets showed promising results in terms of thermals and performance, stability issues arose in more demanding applications like Blender. This instability highlights the variability and risks associated with undervolting.
Conclusion: Evaluating Ryzen 7600X's Cooling Needs
Assessing Cooling Solutions for Zen 4 CPUs
The Ryzen 7600X, while capable of operating at high temperatures, benefits from more advanced cooling solutions. However, our tests showed that even a standard box cooler like the Wraith Spire can manage its thermal output reasonably well.
Recommendations for Potential Buyers
Users considering the 7600X should weigh their cooling options carefully. While liquid cooling offers the best thermal management, air coolers, and even box coolers, can be viable alternatives depending on the use case and performance expectations.
Future Outlook and Cooling Innovations
As AMD continues to develop its Zen 4 CPUs, cooling solutions will remain a critical aspect of their performance optimization. Users should stay informed about the latest cooling technologies and their compatibility with high-performance CPUs like the 7600X.
