Hey LTT community,
Like the title suggests I have two Nvidia Titan RTX GPUs and I'm running them in NV-link for deep learning purposes (sorry, not a gamer ). I have a Fractal Design Meshify S2 TG case with five 14cm fans (see pictures, three push (front), two pull (in rear) to create overpressure) but the top card keeps thermal throttling under load.
I've read that the dual fan cooling is not ideal for multi gpu setups, but I am still asking if there is a way to improve airflow or any suggestions you guys might have to prevent thermal issues.
I'm using the 4-slot nv-link bridge to create as much space as possible but still no luck. I looked at watercooling the GPUs but since they are not mine, I cant take them apart to mount the waterblock.
Any suggestions are welcome! I currently lose out on about 20% performance due to thermal constraints :(
PS. the case fans are set to full power, gpu fans are controlled by Nvidias drivers (under ubuntu) but go up to max rpm under load so its not a fan issue.
Also, I took off the glass panel to take the pictures but that is on when I run the system (dustfilters would be useless otherwise ? )
