Tried out using 2x Phanteks T30s for deshrouded GPU fans. These seem to work well with the Zotac 3080 Trinity/Holo as well as the 3090 Trinity.
Zotac's 3080 Ti cards appear to use a 5mm thicker heatsink so those cards are probably better off on NF-A12s instead.
P.S. Don't expect wonders with noise levels from these fans, unlike what reviews indicate when used with AIOs for CPU cooling. They're more flush with the Zotac 3080s whereas my previous Gentle Typhoons required spacers, but it has the same issue with turbulence causing a lot of noise like Zotac's 3080 stock fans - both became unbearably loud past ~70% fan speeds on the stock fan speed mode. Didn't have the same issues with noise when using Gentle Typhoons at 1850rpm.
