Know before you buy
No, this block is specifically engineered for the PCB layout of the NVIDIA GeForce RTX 4090 Founders Edition. It will not fit aftermarket cards from manufacturers like ASUS, MSI, or Gigabyte, as their PCB designs differ significantly.
The included backplate provides structural support and helps dissipate heat through passive conduction. While it covers the rear of the PCB, it does not feature active liquid channels.
This block uses standard G1/4 threaded ports. You can use any G1/4 compression or barb fittings compatible with your specific tubing size.
The thermal pads are included in the package, but they are not pre-applied. You will need to cut and place them on the designated areas of your GPU during the installation process.
The block features a standard 5V 3-pin ARGB connector. This allows you to sync the lighting with your motherboard's software or a dedicated ARGB controller.
No, you should avoid mixing this nickel-plated copper block with aluminum components in your loop. Mixing metals can lead to galvanic corrosion, which will damage your cooling system over time.
