PC coolant additives provide protection against contamination from biological growth and prevent water block corrosion in a liquid cooled PC. Even in a closed-loop water cooling system, biological agents like algae can grow and thrive, clogging restrictive areas and clouding your PC’s coolant. With all the different materials present in a modern water cooled PC, corrosion is also a constant possibility. PC coolant additives are designed to prevent both from happening in your liquid cooled PC. It should be noted that most premixed and concentrate PC coolants already contain additives to prevent biological growth and water block corrosion. PC coolant additives are however needed when using distilled or deionized water. TITAN RIG offers PC coolant additives from leading brands to protect your PC’s water cooling system from contamination and corrosion.
