I've revised my opinion, just played Forza horizon 5 then flight sim. CPU temp was usually around 64-66 with one spike to 74, Much quieter than the prism when it's not doing cinebench. I think at full fan speed there's not a lot of difference in cooling performance but with normal loads the Noctua is miles quieter.
I also have done some experimenting, I've tried with 2 rear 80mm fans, no 80mm fans and one or 2 CPU fans. The best balance of noise/performance I've found is one exhaust fan and 2 CPU fans. The second CPU fan doesn't do much tbh but I bought it so I'm using it
