Welcome to the Corsair Hydro X series, our custom water cooling category. Here you'll find 25 essential components—from fittings and tubing to pumps and radiators—priced from $12.08 to $99.93. Build a quiet, high-performance cooling loop tailored to your system.
Our guides help you plan a loop, choose the right parts, and fill/maintain it safely. We also cover iCUE integration for pump and fan control.
Custom Loop Builder
Start with a compatible CPU and GPU water block, then pick a pump, radiator, fittings, and tubing. Prices vary: fittings start at $12, while a pump can cost up to $99. Measure your case for radiator space (120/240/360mm) and decide on soft vs. hard tubing. Our Hydro X loop planning tool helps you select the right components and ensure compatibility.
Match the fitting size to your tubing (e.g., 10/13mm). Also consider the threading (G1/4) and whether you need angled fittings for tight runs. Start with straight fittings and use 90° or 45° as needed.
Fill the loop slowly with coolant, power the pump via a separate PSU jumper until bubbles dissipate, then top off. Drain and replace coolant every 6-12 months to prevent algae and corrosion.
In iCUE, you can control the pump speed based on coolant temperature. Set a fan curve to optimize noise and cooling. The XD5 pump also supports RGB customization.
