Leaked renders of what appears to be either a custom-designed RTX 4090 or RTX 4080 from GALAX have appeared online. We know this is a newer card as it has the 16-pin (12VHPWR) connector located right in the middle. The card is massive too, with a quad-slot design!
As I mentioned we do not know what SKU this is from GALAX, and it is not noted on the design at all. There is an interesting 4th fan on the back of the card and the previous Serious Gaming line from Galax featured the same type of fan, so maybe this is a successor to that.
As you can see from the photos the card does have a triple-slot cooler design with of course that fourth fan on the back. It looks like the shroud as well as the rear fan will feature RGB lighting. With the fourth fan the card is likely to be thicker than 4 slots too! The back of the card has a full-cover backplate.
