I upgraded two years ago to a Ryzen 5700 rather than a 5800 specifically for the lower TDP. I rarely max out the cores and the cooler system means the fan rarely spins up to audible levels.

Most (if not all?) BIOSes today will let you limit the TDP - on AMD it’s often called eco mode.

Cool, can you tune exactly how many watts or just on/off?

There are usually a few presets, e.g. 65W or 45W ECO modes for a 105W part, or you can set your own specific values for PPT/TDC/EDC.

Nice!
