PC coolant concentrates are designed to be mixed with distilled or deionized water prior to adding to a liquid cooled PC. While coolant concentrates require a little more effort by the user, they are normally more economical than premixed PC coolant. PC coolant concentrates contain the same inhibitors and additives as their premixed counterparts, simply with less water. By mixing the coolant yourself you can save on the coolant cost and possible shipping expenses. The clear varieties of coolant concentrate are also able to be dyed in the same way as premixed coolant. TITAN RIG has PC coolant concentrate available in clear as well as both translucent and opaque colors to give you the choice you need for your next custom water loop.
