Bitspower unveiled the Summit ELX line of CPU water blocks optimized for 3rd generation AMD Ryzen Threadripper processors. The block's coolant channel is designed keeping in mind the layout of the "Castle Peak" MCM, such that coolant flows over even the CCDs farthest away from the center, which has the I/O controller die. This design should particularly benefit users of the Threadripper 3990X, which has eight CCDs. The block supports both sTRX4 and older TR4 sockets.The primary material is nickel-plated copper, with a mirror finish at the base. There are three variants based on the type of top. The first one called "DRGB," (BP-CPUELXTRX40-DRGB), features a clear acrylic top with embedded addressable-RGB LEDs that plug into a standard 3-pin ARGB header. The second variant is called "Metal" (BP-CPUELXTRX40-MT), and features a metal alloy top with a chrome finish. The third variant, called "POM," (BP-CPUELXTRX40-POM), features a matte-black POM acetal top. The Summit ELX supports standard G 1/4" fittings, and measures 115 mm x 75 mm x 18 mm (LxWxH). The DRGB variant is priced at NTD 2,800, the Metal variant NTD 3,255, and the POM variant NTD 2,635.
