Know before you buy
No, this specific model is designed exclusively for RTX 4090 cards that follow the Nvidia Reference PCB layout. You should verify your specific card's PCB design against the reference layout before purchasing to ensure compatibility.
The chrome plating provides a highly durable, scratch-resistant finish that protects the copper base from oxidation over time. This ensures the cooling surface remains efficient and maintains its aesthetic appeal throughout the lifespan of your custom loop.
Yes, the backplate is essential for providing structural support to the heavy RTX 4090 card, preventing PCB sag. It also assists in passive heat dissipation, helping to manage temperatures across the rear components of the graphics card.
The cooler features digitally addressable RGB LEDs that use a standard 3-pin 5V connector. You can connect these directly to your motherboard's ARGB header or a dedicated lighting controller to sync the effects with the rest of your system.
With a fin thickness and spacing of 0.4 mm, the block is designed for high efficiency but can be sensitive to debris. Using a high-quality coolant and ensuring your loop is thoroughly flushed during assembly will minimize the need for maintenance.
