Temperature gradients and boost clock in detail
The cooler honors its name and keeps the card sufficiently cool. After all, 72°C in open construction and a maximum of 75° in the closed housing are now nothing to scare you. The higher Power Target ex works ensures that the clock still plays along quite well. The Founders Edition is much slower and, above all, hotter.
And now the whole thing again in sober numbers in table form:

Board Analysis: Infrared Images
The following image gallery shows all infrared images for the gaming and the torture loop in the open structure and in the closed case. The differences are very clearly visible, but the cooler still acts quite confidently. As with the Founders Edition, the problem zone is more about memory than GPU and Power Stages.
Since the memory modules are also indirectly cooled via the backplate, they are of course a little cooler when the backplate is mounted. Test measurements with mounted backplate and thermal sensors revealed a delta of up to 4°C at the bottom of the board. However, how much of this really arrives at the top of the modules can only be guessed at. But it definitely helps.
By the way, it is nice to see on all pictures that the thermal pad is superfluous for the GPU. It is cooled well enough from above!
Radiometric Videos: Heat Flow History
The same applies to the backplate as has already been written for the IR images. However, it is interesting to observe how the board heats up within the first 15 minutes. For this I tried the time-lapse and increased the speed tenfold.
The whole thing again with more realistic use in the closed housing:
