Highly efficient
I have just changed my PC completely. I paired this 3080 with a Gigabyte X570S AORUS ELITE AX CM and a Ryzen 7 5800X3D (cooled by a Dark Rock PRO 4). For the RAM, I used Corsair Vengeance LPX 32GB (2 x 16GB) DDR4 3600 C16. With this configuration, in nominal, I get a nice score of 16 115 on 3DMark (Time Spy) respectively 17 283/11 736 for GPU/CPU scores. Average frequency 1 762 MHz. As much as to say that it "deboîte" severe. =)
The disadvantage of the "Air blower" system is that it is relatively noisy. That said, my last PC dates back to 2011... So, I can't really compare with the "Air Flow" systems with 3 fans. On the other hand, the 2 big advantages of the "Air Blower" are:
1- 2 slots format (instead of 3), so more compact.
2- The GPU does not blow all its hot air to the CPU. This could cause CPU throttling. The air is sucked into the case and then expelled from the back.
In order to optimize the noise a bit (and facilitate the RTX 3080 boost mode), I installed MSI afterbruner to do some undervolting (lower the operating voltage). I was able to go down to 900mV and gain almost 6/7°C!
As a result, the RTX3080 is less noisy, because the CPU is no longer at 100% when a game is launched.
Last optimization, I installed Argus Monitor in order to control the fans of my case according to the temperature of the CPU and the GPU! With this "optimized" configuration, I get a nice score of 16,710 on 3DMark (Time Spy) respectively 18,065/11,728 for the GPU/CPU scores. Average frequency 1 884 MHz. One notices the advantage of undervolting. The boost mode works better!
To give you a last figure before/after optimization, 3D Mark gives me an average temperature of 78°C before and 68°C after. With less decibel.
In game I'm at 72°C under God of War (2k/QHD). In short, at the top but requires a little bit of tweaking to give its maximum.
