Don't like the look of them, not very good for extreme overclocks, doesn't support the 660W BIOS, and I experienced the 110c memory temperatures with a couple of the 3090 FEs I tried. Though I know the latter is not a problem with the newer FE models. AIB all the way for me, same with the AMD cards tbf.
I agree with this. Was put off with the 3090 FE's noise, vram temps. The 4090FE is even louder than the 3090FE, so big no for me. The AIB models are so much quieter, support higher power limits, no brainer.
