Yesterday night I finished building the custom water loop on my Vega 64.
I started building stuff late in the evening and it got quite late until 2:00 o'clock.
I did only one test so far. I played Witcher Wild Hunt for around 40 minutes leaving the Wattman settings at default Balanced mode.
I was able to achieve average clock of around 1528MHz with the GPU temperature staying on average at 39°C at room temperature of 24°C. These temperatures are great.
The maximum temperature of the GPU was 42°C. The maximum GPU frequency was 1630MHz.
The frequency measurements were done with Wattman as well as GPU-Z.
I will repeat the test tonight and make some screen shots as I did not make any yesterday.
This result is very close to what Tom's got in the Witcher with Turbo mode.
In my case the Wattman is on balanced mode and I achieve average of 1528MHz in Witcher.
I will do further testing tonight with Turbo mode turned on to see how high the average clock can go on my Vega 64 sample.
I bought a Saphire aircooled Vega 64. It is a variant where the GPU chip and HBM2 have same height and there is Epoxy filling between GPU and HBM2.
I used IC Diamond 7 Carat as thermal compound on GPU and HBM.
The undervolting test will come in the next days.
With original cooler it was hitting 85°C all the time with default fan profile.
To achieve lower temperatures in range of 65°C on the blower cooler, the fan speed needed to be increase above 3300RPM.
It was like sitting next to a Vacuam cleaner!!
The average clock there with high fan RPM was always below 1430MHz.
I did further tests concerning this topic.
I put the results in the Owners club section here:

The results look very promising.
