Full-coverage GPU water block

This full-coverage GPU water block fits ZOTAC Gaming GeForce RTX 4090 Apocalypse OC, AMP Extreme AIRO, Trinity OC and Trinity graphics cards. It directly cools the GPU core, memory and VRM using nickel-electroplated high-purity copper and an acrylic top. A black anodised aluminium backplate is included but does not contact coolant. G 1/4 in. threads accept standard fittings.

Cooling capacity and headroom

Direct contact with the GPU core, memory and VRM lowers temperatures below stock levels and provides headroom for higher overclocks. The high-flow design supports multiple blocks in series and allows parallel or serial port configurations for custom loops. Cooling limits depend on the rest of the loop and the card's PCB layout, which can vary between models.

Included accessories and lighting

The package supplies the water block, backplate, two stop fittings, mounting hardware and thermal grease. A 5 V addressable RGB (RBW) light is included; a 12 V 4-pin RGB version is available on request. The RBW connector works only with addressable RGB headers — mixing with 12 V RGB will not function. Verify PCB layout before ordering.

Questions about this item

Will this block fit my Zotac RTX 4090 Trinity OC without changing the existing backplate?

The block includes a black anodised aluminium backplate and mounting hardware that replace the stock cooler entirely; no original parts are reused.

How can I verify the 5 V A-RGB lighting is functioning after installation?

Connect the 3-pin 5 V ARGB header to a compatible motherboard or controller, then use the board's RGB software to confirm colour cycling.

Which fittings and coolant additives do I need to purchase separately?

The box supplies two G 1/4 stop fittings and thermal grease; you must buy G 1/4 compression or barb fittings for your tubing and your chosen coolant.
