Message: [QUOTE="Nehanda, post: 29856, member: 2262"] Noctua plans to release a liquid cooling system in 2026 that uses the thermosiphon effect instead of a pump. The cooling happens by itself - the CPU heats liquid in a special block, which then changes to vapor and travels upward through pipes to a radiator with two 120 mm fans. Once the vapor cools and becomes liquid again, it simply flows back down to the CPU block. This happens because of heat differences, not mechanical pumping. The design reduces common problems like noise and breakdowns that plague pump systems. Though the setup doesn't have a pump, it still makes some noise from the fans that help remove heat from the radiator. The system functions similar to a heat pipe, with natural movement pushing coolant through its closed circuit. This passive approach cuts down on vibrations and mechanical failures compared to standard cooling options. Installers must place the radiator at the case top, with pipes arranged at specific angles for proper liquid flow. This requirement means the system works great with many current cases that feature top vents but might not fit every design. The 280mm radiator can squeeze into compact systems, making it attractive for tech experts who want reliable cooling without pump headaches. When Noctua brings this product to market in 2026, users will need to follow stricter placement guidelines than they would with regular all-in-one coolers. Despite these limitations, many computer enthusiasts will likely appreciate a cooling solution that eliminates pump problems. [/QUOTE]
