Notes Alphacool asks that the block be used only with clear transparent water cooling fluids. It warns that the particles and additives in Pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses, and that this can void the manufacturer's warranty. Remove the original cooler on an antistatic mat and clean the card of thermal paste and pad residues before fitting the block.
