Just like the Gigabyte RTX 3080 Eagle OC, this cards will emit a lot of heat and needs a case with good cooling. As I already had updated my Lian-Li O11 Dynamics case with several Be Quiet fans I do not know how hot the case would have been with just this card.
Overall though I was very satisfied with the temperatures that I measured.
At idle the GPU temperature is around 50C. The fans stopped spinning at low load and idle so the card itself was completely silent. I measured around 33.5 dBa 50 cm from the front. If you would like lower idle temperatures setting the fan curve to slowly spin the fans should help lower this temperature. The power draw from the board is around 35 W (from the wall I see 135 W for the whole system).

Board power draw
Running the new Bright Memory: Infinite Ray tracing benchmark in a loop yields these results. If you compare to those of the Gigabyte RTX 3080 Eagle OC you will notice they are almost exatly the same (although in that case I was running the 3DMark stresstest). I guess we should not be surprise that the results are very similar.
The power draw of the board is about 335W (at least as measured by GPU-Z). What is interesting is that accoording to GPU-Z we are never limited by the Power target always staying at around 95% max. This is in contrast to the Gigabyte RTX 3090 Eagle OC where we always were limited by the power target.
