How to Choose Custom Loop Parts

Map the cooling path
CPU block, GPU block, pump, reservoir, radiator and drain route should be planned before buying fittings.
Match tubing and fittings
Hard tube, soft tube, diameter, thread type and compression fittings must match exactly to avoid leaks.
Balance radiator capacity
Heat load, fan size, case space and noise target decide radiator thickness and surface area.
Avoid material conflicts
Copper, nickel, brass and aluminium parts should be chosen carefully with compatible coolant and maintenance intervals.

Loop tip: Leak-test a finished loop before powering hardware. Most custom-loop problems come from rushed planning, mixed fittings or poor drain access.

Frequently Asked Questions

Hard tube or soft tube?
Soft tube is easier to build and maintain; hard tube looks cleaner but needs precise bending, cutting and fittings.
How much radiator do I need?
It depends on CPU/GPU heat, fan speed, noise target and case airflow. More surface area usually lowers noise.
Can I mix metals in a loop?
Avoid aluminium mixed with copper or nickel loops unless the coolant and parts are explicitly designed for it.
