I ran into the same issue when researching Heatsinks. Some manufacturers list the TDP rating while others don't (Noctua, Scythe, etc.) I contacted Noctua to find out why that is the case and they gave me the following explanation (sorry in advance for the long read):Looking at different CPU coolers I can never find the wattage rating.
I don't view manufacturers that do list TDP values as trying to 'mislead' consumers since as it relates to performance data, the value listed is only based on the build on which the test was performed. It's virtually impossible to test a heatsink in every possible build configuration so whenever I research component specs, I realize the values are just estimates. Probably the only spec that is concrete is the dimension, shape and color of the component.I like that they arent being misleading.
LOLThe kind of engineers at a certain manufacture that say the I9 9900k is only 95w are like the philosophers that think the world is flat.
Except the ancient philosophers didn't know the truth, but the engineers know the i9 draws >200w. This still miffs me to this day.
EXACTLY!! So for those people the TDP Compatibility Guide is fine. However, for the tech savvy people such as yourself and others--I'm not including myself since I'm still learning--I think an average figure should be included on their spec page. The same data/benchmarks they used to compile the TDP Compatibility Guide could've been used to include an average TDP value with the rest of the specs.That's only because many ppl are clueless as to exactly what constitutes TDP.
I've been confused about TDP as well, while buying the parts to upgrade to an AM4. I see 65W TDP on a Ryzen 2700 and 105W on a 2700x... figuring I should see a similar number (or maximum TDP) on the mobo (which I can remember seeing when I first starting looking at upgrading a year ago.It is just a pet peeve of mine, I was wanting to change my cooler and the ones I was looking at didn't show the wattage on the sales site or the Manufacture's site. I have tried googling but it seems like the info is not out there for what I was looking for. I remember when I could find a lot more answers on google 10 years ago , now when you search the just want to sell you something!
