Question about MSI GeForce GTX 1080 Ti SEA HAWK X

My idle temperature averaged between 29-32°C.
Of course, factors such as room temperature, which enclosure size (midi, high, big tower, etc.) and how many fans are already in the enclosure play a role. (Midi, High, Big-Tower..etc) and how many fans? are already in the case.
The "Corsair" fan for the pump always turns at a minimum of 29%, which is about 1100 rpm.
I don't find it loud or unpleasant.
Under load I tested it with "Unigine Superposition Benchmark".
4 tests in order. ( The 8K test was only "Just4Fun" ^^ )
Between the tests, it was "idle" for about 30 seconds max.

1080P Extreme: min 30°C - max 55°C
average 43.76 FPS <-- kp why...

4K Optimized: min 40°C - max 58°C
Average 69.11 FPS

8K Optimized: min 36°C - max 57°C
Average 31.18 FPS

1080P High: min 42°C - max 59°C
Average 111.30 FPS

I also like that the card cools down relatively quickly ;-) atm while writing 31°C.
Tested with a 6850k CPU (not overclocked!) on Win10 Home.

-without warranty-

According to the first experiences (google and co) not over 63.
We can say more precisely when the first people here have one (tested it themselves) ;-)
Hopefully tomorrow for me.

Nice, how quickly they went. (Compared to the other MSI Customs)
