I recently got my hands on an RX5600XT, and I’m thinking of using it as a base for swapping fans and reshrouding, kind of like a normal deshroud just without a ziptie and hopefully a bit better looking? Maybe.

So I took the card apart and the heatsink fins are 88mm wide and 235mm long. I’m a bit torn between using 92mm fans or 80mm fans. Would it be better to use a 92*276 with a lot of the airflow “leaking”, or a 80*240 that doesn’t fully cover the width of the heatsink?

I recall an old r/sffpc post about how most of the pressure and airflow is generated at the fan blade tips, but have never tested this myself. Also Arctic only makes P8s but not P9s, which means I would have to find an alternative 92mm fan.

Also, is it better to have the fans pressed flush against the heatsink, or have a bit of clearance (like 5 to 10mm)
