Tctl sensor values and many new questions

We already know since the launch of the larger Ryzen 7 CPUs and the follow-ups to Ryzen 5 that the display of the temperature values at the current Ryzen CPUs is at least not without problems. We had already examined these circumstances in great detail and therefore want to save ourselves a direct repetition of all measurements and justifications. If you would like to, you can read all this again here.

Once again, Alphacool's "Ice Age 2000 Chiller" is used with the usual 1/4" threads and a powerful pump, which we use parallel to the Boxed cooler to determine the remaining delta values.

Temperature vs. Power consumption

Since the cooling used for all measurements is absolutely independent of the actual waste heat supplied, we have again compared the Tctl values and the actual power consumption. In order to be able to compensate for various jumps and time delays as well as possible, we have gradually created different loads over a longer period of time with a self-programmed tool, which we then divided equally between the possible threads (or respectively). had hoped so). The result obtained in this way also confirms what we have already suspected:

Below approx. 20 to 25 watts, the temperature values emitted are therefore smooth nonsense. But we also see that between Ryzen 3, Ryzen 5 and Ryzen 7 there is once again a clear difference in the AMD-own interpretation of the Tctl values! What surprised us a little is the fact that obviously there was no explicit mark-up with the X-model of the Ryzen 3 this time, because the values for the Ryzen 3 1200 were very similar. Of course, this can also be related to the new BIOS version of the motherboard, so we don't want to make hasty speculations here.

However, we suspect that the Tctl values are only calculated/estimated internally internally and that when the core number decreases, the division is simply not quite correct. For our taste, everything is clearly too high. That is why we are using a corrective delta later on, which is based on our comparison curves.

Effects on air cooling

In order to bring more practical relevance into play, we tested the Ryzen 3 with the enclosed air cooler and set a fixed speed of the fan, as it was required during a first test run at full load. Here, too, we can still see the two kinks in the curve very clearly, even if the curve rises much steeper overall.

The Ryzen 3 1300X acts very similarly, although we could hardly detect leakage currents.

Adjusted temperature values with water cooling

Let's stick to the temperatures and compare all Ryzen CPUs adjusted again, including the respective predicted additional delta for the three power sub-ranges and the respective processor family:

Volume of the Boxed cooler

Both Ryzen 3 belong to the 70-watt class, which can be easily dissipated as waste heat even with such a simple knitted aluminium block. Depending on the motherboard and interpretation of the fan profile, the fan operates between 33 and 36 dB(A), which can be described as good. It really isn't really loud.
