help identifying a strange FX 5950 variant

I've owned this 5950 ultra for a long time, probably since around 2008-2009 I think. It came into my possession as part of a computer I scrapped that included a soyo SY-P4I875P dragon 2 platinum motherboard and was inside a strange white bubble shaped case I wish I still had. It's got a brilliant red PCB but is using the reference cooler design. The heat sink is toughly stuck down to the gpu so I've not dared to try and pull it off completely to look to see what's under there. But in windows xp it comes up at a geforce fx 5950 ultra. Maybe someone here would have ideas how to id this variant? I've looked on google but I can't find any with this heat sink style with a red pcb. https://imgur.com/a/lvo46wI
