I have an 80mm noctua high flow intake, but even with that the Yeston 3050 immediately approaches 90C in Superposition benchmark and then thermal throttles, bringing the score down by 2000 points between the first and second run.

I'm in an Optiplex 5050 case with an i7-7700. Stock cooler, all that's changed is the intake to 80mm (Daisy chained form CPU cooler).

The CPU temp is acceptable for the most part, only getting into the 60s while benchmarking superposition (high 80s with prime95). So I think the CPU cooler is sufficient even in stock configuration.

I have two ideas:

drill a hole in the side of the case and attach a 140mm fan as intake. That should keep the GPU from recirculating its own heat I would hope
create a duct from the 80mm intake to the GPU intake directly, and add a second intake fan for case air to the outside of the case still

Has anyone successfully kept one of these cards cool under heavy load in a sff case? I'm not afraid of modding the case, and I think the external 140mm fan would probably be good. I'm just worried that at that point the exhaust would become insufficient.

Edit: should probably mention I also intend to undervolt the card. I'm aiming for a heavy load temp of under 80C maximum

Edit: thanks everyone for responding. I was able to get the temperatures into an acceptable sub 85 range by running the noctua at full speed. I never tried swapping the card to the other slot but I'd imagine that could save a degree or two as well

How will this build do?
