Question about be quiet! Pure Rock 2 FX

The be quiet Pure Rock 2 FX (155 mm) is a powerful CPU cooler, but for a high-performance processor such as the AMD Ryzen 7 5800X with 8 cores and a clock frequency of 4.7 GHz, it may not be sufficient under certain conditions.

Here are some important points to consider:

- TDP classification: the Pure Rock 2 FX is rated for a TDP of up to 150W, which is basically sufficient for the Ryzen 7 5800X, which has a TDP of 125W. However, the actual power consumption of the processor may be higher under load.
- Performance and volume: The cooler has four 6 mm heatpipes and a quiet but powerful fan. However, it can become audible at high speeds and under high load. It is important to adjust the PWM settings in the BIOS to achieve the best balance between performance and volume.
- Compatibility: The cooler is compatible with the AMD AM4 socket on which the Ryzen 7 5800X runs.

Summarised: The be quiet Pure Rock 2 FX can cool the Ryzen 7 5800X, but it may be necessary to adjust the fan speed and PWM settings to achieve optimal performance and noise levels. For very demanding workloads or checking maximum performance, a cooler with more thermal headroom may be required.
