Graphic Cards Need 3080 fan heatsink


hi guys i have a 3080 aio gpu since 1 year and put up for sale here but i cant find buyer for it

i've been thinking to buy a external gpu for quite long time. so im thinking why not convert this aio 3080 to fan heatsink 3080

can anyone point out where i can buy a 3080 heatsink with low profile that is compatable with my GIGABYTE AORUS GeForce RTX 3080 WATERFORCE

Thank you so much in adavance :D
