Details
The Alphacool Core GeForce RTX 4090 Founders Edition with Backplate is a GPU water block for the Nvidia GeForce RTX 4090 Founders Edition graphics card. It cools the card with a chrome-plated copper block under an acrylic top, and the black aluminum backplate is in the box.

Compatibility
Alphacool lists this card for this block:
- Nvidia GeForce RTX 4090 Founders Edition, 24GB GDDR6X (900-1G136-2530-000)
The block was designed for one PCB layout, and card makers sometimes revise a board so that a cooler no longer fits later models. Before ordering, compare your card and its PCB number with the pictures in Alphacool's GPU Configurator, or look it up in its Compatibility List for Nvidia cards. Alphacool's Eisblock Aurora block for the same card is the Eisblock Aurora Acryl GPX-N RTX 4090 Founders Edition.
Copper cooler and terminal
The core of this block is the copper cooler, which, like the end terminal, is milled from a single piece of copper. A hard and resistant chrome plating covers the entire copper cooler, so the cooler is made entirely of chrome-plated copper. Alphacool says the fine workmanship paired with that plating meets the highest quality standards. The chrome-plated brass G1/4 threads are integrated on both sides and stand out visually from the terminal. Alphacool names them a central feature of the new design language of the Core series. Its own line for the product series is that Core is characterized by high quality, outstanding performance and a uniform, functional design language.
Chrome plating
Alphacool says a chrome plating is much harder than a nickel plating and therefore less sensitive to acids, scratches and damage. It says chrome completely eliminates the risk of chipping nickel plating. Additionally, it says, chrome looks much more homogeneous and provides a shine that cannot be achieved by nickel. Chrome-plated coolers have previously only been used in the industrial sector, in areas where extreme influences act on the coolers.
Technical highlights
Alphacool says the technical advancements can be seen in the water supply to the jet plate and in the jet plate itself, which was completely redesigned based on many simulations and practical tests in cooperation with board partners. The fin thickness and spacing have been enhanced, the cooling surface has been increased and the water flow to the core components with the greatest heat output has been optimized. The cooling fins are 0.4 mm thick with 0.4 mm between them, and the cooler bottom is 11.3 mm thick.
Design and lighting
The aluminum backplate is adapted to the design and, together with the terminal, makes up the entire unit. Alphacool says it gives the back of the cooler a clean and homogeneous look. The lighting consists of 12 digitally addressable RGB LEDs, which illuminate the entire cooler evenly and effectively.
Thermal pads
Alphacool says the enclosed special soft thermal pads, with up to 7 W/mK, adapt perfectly to even the smallest tolerances. Thermal grease and a putty tool are also in the box.
What the loop needs
The block has four G1/4 threads. Two take the compression fittings for your tube size, which are not in the box, and the other two take the two plugs that are. The lighting connects through a 3-Pin JST plug, and an ARGB adapter is included. Thermal pads, thermal grease, a putty tool and the PCI bracket also come with the block.

Notes
- Please use the block only in conjunction with clear transparent water cooling fluids. Alphacool warns that the particles and additives in Pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. This can result in voiding the manufacturer's warranty as well.
- Remove the original cooler on an antistatic mat and clean the card of thermal paste and pad residues before you place the pads and fit the block.
