Installation and commissioning
What has disadvantages (water block not so easily rotatable), of course also has advantages. That's why we don't pull anything off in the B-note. The assembly with the fixed screws is absolutely unproblematic and the stoppers also guarantee that the pressure does not become too large. So you can screw relaxed by hand (!) until the stop. Finished.
Stress test at the factory clock
In the stress test we register a power consumption of 180 watts, the determined values for Tctl are 65.5°C after a few minutes. Since the value for our taste was too far lower than that of the Alphacool XPX used at launch, we repeated this measurement again with the other cooling block. Interestingly, this time, there were significantly lower values in the log, but with a different curve curve.
The results for Tdie, i.e. the package, were once again significantly lower than at the launch. And while at the launch Tctl and Tdie offered completely different courses, the two values are now very similar, at least in the course shape. But it should get even thicker…
Stress test at the OC and approx. 320 watts
This time we have been able to overclock the CPU even higher and end at a nice 4.0 GHz clock for all cores. If we now look at the temperature values for Tctl, there are big, fat question marks in our eyes! What the hell does the CPU actually return to sensor values? The higher the power consumption, the lower the temperatures?
When evaluating Tdie, we are completely perplexed, because with less than 25°C, all this is only approx. four to five Kelvin below the constant water temperature of 20°C!
Error in BIOS possible after AGESA update
We have therefore tested against it. New Windows image with old and new drivers? Misreporting. Switch between three motherboards of different manufacturers (Asus, Gigabyte, ASRock)? Again, nothing. The flashing back from BIOS 0503 to 0304 suddenly brought back the old temperature values, but also the known stability problems.
We therefore suspect the cause of the error is the Agesa Code 1003 Patch 4, which now incorrectly outputs the calculated temperature values. What still looks reasonably plausible at the factory clock is then simply wrong with the OC. We also see a real threat to stability when power consumption increases, but return values fall and, for example, the return values fall. the fan curves based on these computational values are reduced far too much as a result.
A counter-test with a significantly weaker AiO and some OC led to significantly lower fan speeds if this PWM-controlled system is controlled by the motherboard. The result was a thermal GAU. You don't have to think about an air cooler anymore.
We have already informed AMD about these measurements, but are still waiting for an opinion or a new BIOS. At the latest, we will of course do a follow-up test.
Summary and conclusion
Very good cooling performance, coupled with a very simple assembly, as well as a more flow-independent performance make the EK-Supremacy EVO Threadripper Edition a buying tip in this product category. If you want to water a Ryzen Threadripper cleverly, you can access here really calmly. Even if AMD's temperature values are amicable, the EK-Supremacy EVO really doesn't have to hide in comparison to one of the best water blocks at the moment.
With approx. 70 Euro street price it is not a complete cheap home, but also not so expensive that one would have to run away in horror. It fits into the overall concept, also financially, into a system with a Ryzen Threadripper: you get something for the money. And this is not necessarily self-evident in this day and age.
