Although a CPU cooler that has a lower TDP rating than the CPU, it can still function. In some cases, the cooler may operate continuously at full speed. If the CPU cooler fails to maintain an optimal temperature for the CPU, it may cause the CPU to slow down. While testing CPU coolers, I observed the importance of adequate cooling in achieving and maintaining maximum boost frequency. At its base frequency of 3.6 GHz, the Ryzen 7 3700X's base TDP is 65 watts. The Ryzen 7 3700X's PPT limit is 88 watts, which can be reached at its max boost frequency of 4.4 GHz. PPT (Package Power Tracking) is an AMD CPU feature that monitors CPU power consumption and prevents the PPT limit from being exceeded to avoid overheating and undervoltage. Since the base TDP isn't an accurate representation of AMD CPU maximum thermal requirements, the peak TDP of the Ryzen 7 3700X can be determined by its PPT limit instead. Using a cooler that can handle the peak TDP of 88 watts is necessary to maximize your CPU's performance. It is crucial to select a CPU cooler with a TDP that matches or exceeds the peak TDP of the Ryzen 7 3700X for efficient heat management.ĭepending on the workload, the Ryzen 7 3700X has a TDP range of 65–88 watts.

The Thermal Design Power (TDP) rating of a CPU cooler refers to its ability to dissipate heat in watts. Thermal Requirements of the Ryzen 7 3700X CPU
