My ongoing issue is that due to the dual blower passthrough design of the nvidia cards, the hot air from the 1st GPU bathes the 2nd GPU:
I recently updated to dual Gigabyte 5090 OC Editions replacing my Nvidia 5090s
The gigabyte 5090s have a more generous cooler and stayed below 39 C at idle with the fans off (normal behavior when not using an app or gaming.
The challenge was the sheer size of the Gigabyte 5090s OC…huge challenge as of the HUGE cards compared to the nvidia FEs.
So this required modding the PC, you can see the modding on this thread:
The final product runs silent (in most cases, unless a heavy gaming session, but even then its not loud)
Under load the cards peak at 68-70C, which was lower than the Founders Edition, but more importantly, when the video card fans are not going, the cards stayed around 39C in a room that is normally about 71F.
