GPU Water Blocks
Tired of your computer crashing in the middle of your game? The most common issue amongst hardcore PC gamers is your GPU or Graphics Processor Unit overheating. GPU water blocks aim to solve that particular problem by transfering heat away from critical points on your graphics card and therefore decreasing your GPU's temperature at both idle and heavy loads. GPU waterblocks feature G1/4" threaded ports for use with all standard PC watercooling fittings and accessories. If you're looking to liquid cool multiple graphics cards at once, we recommend using a bridge connection block to unify your GPU loop. Blocks from certain brands like Aquacomputer and Alphacool come in a variety of materials and styles for each person's individual tastes and PC cooling needs.
