Managed to get my hands on a few 3090FE only to realise the cooling, while interesting looking, is not as good as the cheapest aib i have.
So i decided to mod it
https://i.imgur.com/fq0TNAK.jpgdropped temps from 110C to 84C. I'm now able to drop fan speed to 50% and removed the fan on the backplate. The heatsink still gets burning hot, so i might need to create a shroud on the rear fan and channel it through the heatsink.
