Watercool Heatkiller V Water Block

No, this specific model is engineered exclusively for the NVIDIA GeForce RTX 4080 Founders Edition. It will not fit custom PCB layouts from other manufacturers like ASUS, MSI, or Gigabyte.

Yes, the package includes the water block, the matching backplate, and the necessary high-performance thermal pads for the GDDR6X memory. You will still need to provide your own thermal paste for the GPU core and the appropriate fittings for your custom loop.

The dual-layer inflow is designed to optimize coolant distribution across the cooling fins, which helps maintain high flow rates. Because of this symmetrical design, the block is generally less sensitive to flow direction, making it easier to integrate into most custom loop configurations.

Like any high-end copper block, you should perform routine maintenance on your loop to prevent corrosion or buildup. Since this block uses a nickel-plated copper base, ensure you use a high-quality coolant compatible with nickel to maintain the finish and thermal performance over time.

Yes, the integrated aRGB lighting uses a standard header connection, allowing it to sync with most major motherboard lighting ecosystems. The modular plug-in system makes it straightforward to connect and manage alongside your other components.

The included backplate is primarily designed for structural rigidity and aesthetic finish. While it helps with passive heat dissipation from the rear of the PCB, it does not feature active liquid cooling channels.
