GPU art: redraw front and back with real detail

Six-blade fans with rim, air duct and hub, graphite shroud with fin stack,
copper heat-pipe ends and an 8-pin connector, PCB with parts and per-contact
gold fingers; back has brushed backplate, vents, screws, recessed silkscreen
plate, QR/barcode sticker and a seal. Overlays realigned.
