Show 60 moreLiquid cooling carries heat from the CPU and GPU to radiators, where fans can shed it with less noise. There are two ways in:
For a custom loop, plan before you buy. Confirm block compatibility with your exact CPU socket and graphics card model, measure radiator space including fans, and choose soft tubing (easier and forgiving) or hard tubing (cleaner look, needs bending tools and patience). Keep to one metal family: copper, brass and nickel-plated parts work together, aluminum does not. Fill and leak-test with only the pump running before you power the rest of the system. The custom water cooling guide walks through a complete loop.
