Temperature gradients and boost clock in detail
The cooler manages, somehow. If it is still 83°C in the open structure, it is then a maximum of 86° in the closed housing. The high power target ex works ensures that the clock still plays along quite well, even though the card is already running to the thermal limit, which makes it a little bit slower than the Founders Edition. In the stress test, the throttling is already much more pronounced.
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, especially since the cooler reaches its limits. As with the Founders Edition, the problem zone is more about memory than GPU and Power Stages.
The memory runs just above the 95°C limits specified in the Specs, especially during the stress test in the closed housing. Only a high-performance housing ventilation helps. Or the water cooling conversion.
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:
And if it were cooled with water? The symbiosis of Turing and Wasserblock can be done in a completely different way at 380 watts and 2147 MHz. Turing on ice instead of Tourette the fan. That is the way it must be!
