Thermaltake entered the custom water cooling market in 2014. Since then, it’s been steadily growing its lineup of products to include radiators, full kits, and full-cover GPU blocks. Thermaltake is now competing against water cooling stalwarts EK and Bitspower by producing ultra-niche products, such as the new Pacific M4 motherboard water block.
This is the company’s fourth motherboard and CPU combo block, often called a monoblock. Like those from EK, the Pacific M4 fits one motherboard only, the Asus TUF X299 Mark 1, and covers both the CPU and the surrounding VRM circuits of the motherboard. The waterblock is fitted with RGB lighting that is compatible with Asus’ Aura Sync ecosystem, but it’s somewhat deficient at only 256 colors.
The construction of the Pacific M4 differs slightly from those we’ve seen from EK. The CPU cooling plate, which uses 0.15mm thick micro channels, is screwed into the bottom side of the main body of the block. Coolant apparently enters directly over the CPU plate and exits above it. The block appears to be made of nickel-coated copper.
We have no availability or pricing info on the Pacific M4 at this time.
