Thermaltake is on a cross-branded products launch spree, and its latest creation is a Pacific M4 monoblock designed for ASUS TUF X299 Mark I motherboard. A monoblock is an enlarged CPU water block that cools even the VRM surrounding the CPU socket, something Intel's "Skylake-X" platform could really do with. The Pacific M4 combines a nickel-plated copper main block, with an acrylic top that's been studded with 256-color RGB LED elements through a silicone diffuser; and a top sticker with Thermaltake and ASUS TUF logos. The RGB LEDs take in standardized 4-pin RGB input, and can be controlled by ASUS Aura Sync RGB software. Heat drawn from the VRM is conveyed by a base-plate onto the main block. The block takes in standard G1/4 fittings. Measuring 154 mm 114 mm x 29.4 mm (LxWxH), the monoblock weighs 770 g. The company didn't reveal pricing.
