Bitspower Orion VGA Water Block for GeForce RTX 4090 Founders Edition, designed for the powerful GeForce RTX 4090 Founders Edition graphic cards, has been specifically engineered to provide the best temperature control while also keeping the aesthetic elegance that Bitspower is known for. We also pre-pasted thermal pad to make it easier for users to install. Covering the full length of the card, the water block is layered with a nickel and chromium plated copper base plate that is meticulously carved to allocate the most contact over the GPU and VRM area.
