Liquid-cooled PCs require regular coolant maintenance to prevent corrosion, clogging, and overheating. Over time, the corrosion inhibitor in coolant breaks down, causing it to corrode internal components and lose lubricating properties. Pigmented or semi-transparent coolants may develop algae and particulates, leading to blockages and reduced cooling efficiency.
Most experts recommend replacing coolant at least once a year, or every six months if using colored varieties. Signs that coolant needs changing include murky appearance, haze, grime, or unexpected CPU temperature spikes. Regular replacement ensures optimal performance and extends the life of your cooling system.
