The maximum temperatures for AMD Ryzen processors are revealed and we know that we will need a powerful heatsink for processors with the 'X' in their name.
In recent days the information about AMD Ryzen does not stop appearing and the latest leaks refer to the heatsinks that AMD will give together with the processors and a controversial benchmark comparison. We now know that the AMD R7 1800X, the AMD Ryzen 7 1700X and the AMD R5 1600X processors will need a high-end heatsink. It is nothing new, we are aware, but the new data specifies a little more about this need. These processors have a TDP of 95W and will use Extended Frequency Range (XFR) technology.
The Extended Frequency Range technology is a very interesting technology that AMD has added to the processors with the letter 'X', which automatically overclocks the processor, raising it in steps of 100MHz up to a limit, which is marked by temperature. The temperature limit will be 59.9ºC, so we must install a heatsink capable of making the processor always work below that temperature or this for as long as possible under this temperature and allow the processor frequency to increase.
As measures to control the temperature, we have the Noctua NH-D14 and NH-D15 and the Cryorig R1 Ultimate, within the air cooling solutions and in terms of liquid cooling, we would look for AIO solutions with a 240-280mm radiator such as minimum, to keep the temperature as deep as possible. The other processors would withstand temperatures between 71.3ºC, which is equivalent to a TDP of 65W, which is the maximum temperature before causing damage to the processor.
There are two PRO models, such as the R7 PRO 1800 and R5 PRO 1600, which have a TDP of 95W and a maximum temperature of 72.4ºC. The rest of the PRO processors would apparently have a 65W TDP. These data already allow us to see where the AMD processors will go with respect to consumption and plan which will be the best heatsinks on the market according to the TDP. It is clear that those classified as HS81 by AMD, will require high-end heatsinks that dissipate heat very efficiently.

Dear, looking at the images you posted in the news, at least what I understand is that that is not the maximum temperature of the processors, it would be illogical because 72 degrees is not much and in general a processor can pass them. At least what I understood is that there would be 3 groups of heatsinks and with that those were the maximum temperatures that the processors would reach with each heatsink, which makes much more sense, since the "thermal specifications" box mentions the specifications of the heatsinks and not the specs of the processors.
On the other hand, the news that they could require special coolers according to me, makes mention of the differences in TDP between processors with the same number of cores and that in general processors with X would have a higher TDP and would require a larger heatsink, probably as much for their higher base frequencies, as per the XFR characteristic
The TDP depends on the frequencies, the number of cores, the processing threads and whether or not they have integrated graphics.
the lower their manufacture is, in this case 14Nm the lower the maximum temperature they support.
It is not that they are going to break, but the processor wears a lot and when a processor or graphics goes above a certain temperature, the performance does not go up, but rather stagnates or begins to fall, in addition, the temperature wear in the long run is harmful .
What will stock coolers not serve?
Stock coolers never serve. Spending € 20-30 is recommended to keep the cooler well refrigerated and thus avoid problems.
At least it lasts for a while so you buy a hyper evo 212 at least.
I put the Noctua NH-D15 on mine, for two reasons, because I live in an area where it is hot in summer and I want it to be well cooled and two, to be able to give it 10-15% OC without having to change the heatsink
