Common Applications

The BS-GAM3090-PA2 is a full-cover water block engineered for the shared MetalTop PCB used on GALAX RTX 3090 and RTX 3080 cards and the equivalent GAINWARD reference designs; it does not fit GALAX GAMER OC, Founders Edition, ASUS, MSI or Gigabyte 3090/3080 cards, which use different layouts. The cold plate is copper with micro-fin channels over the GA102 die and pad zones across the GDDR6X modules and VRM, and the top is acrylic. Inlet and outlet are standard G1/4 BSPP, and a matching metal backplate ships in the box. Lighting is Barrow LRC 2.0 5V 3-pin addressable RGB, which connects to any motherboard A-RGB header or controller; a 12V RGB header will damage the LEDs.
