All things defined, TDP in watts equals the (difference between recommended max CPU temperature and recommended max ambient temperature) divided by (maximum recommended thermal resistance of heatsink). TDP is a result of plugging recommended room temperature, CPU temperature, and cooler quality into a formula and getting a hard number out, even though the variables that go in can be freely defined and data can be massaged to equate nearly any TDP value, as you’ll see below.https://gamersnexus.net/guides/3525-amd-ryzen-tdp-...

TDP is an overly reductive number, and it’s only becoming more difficult to define with features like AMD’s Precision Boost 2 that make every individual processor perform differently in different situations. The safe assumption is that any TDP rating, whether it’s from AMD or Intel, is just an easy-to-swallow marketing device that looks good on a box. When buying a cooler, it’s a far better idea to check the cooler manufacturer’s website for recommendations: many have moved away from listing TDP entirely in favor of detailed CPU/cooler compatibility lists. NEVER try to compare Intel and AMD CPUs to each other based on the manufacturer-provided TDP, especially not in all-caps forum posts. It’s not even advisable to make concrete comparisons between different AMD CPUs using TDP. Read a review, pick a CPU, check the website of a reputable cooler manufacturer for recommendations.
The AK400 is not necessarily a cooler we’d really recommend for that 120W range, but it is capable and as long as you’re using a case that doesn’t suffocate the cooler’s access to air you should be fine, unless you start overclocking.
