Woulda been simpler from a manufacturing pov to just produce the same cooler for 2 cards you'd think.
Exactly, and what they did with the 4080 and 4090. The cooler was over-engineered for the 4090, let alone the 4080.
I've just had a quick look on the bay and there are loads of 4090FEs that have sold for like £1700-1800ish in the last day or two - nuts!
