420mm Radiators

420mm Liquid Cooling Radiators

A radiator is just as important as the water cooler itself in a water-cooled system because it is the radiator that must remove the heat absorbed by the water. This is achieved through its finned surface, which is cooled by a fan in the case of an active radiator. A 420 mm radiator can accommodate three 140 mm fans. 420 mm radiators are particularly suitable for big towers, as they offer extremely good cooling performance and require a lot of space due to their size.

Material, cooling performance, and sufficient space are crucial

For the 420 mm radiator, as with all other radiators, attention must be paid to the fans to be mounted on it, its cooling performance, and its material. Copper or brass is usually used as the base material for a radiator and may additionally be nickel-plated. The frame, on the other hand, is often made of stainless steel or aluminum. It is important to ensure that the material of the radiator matches the rest of the water loop to prevent chemical reactions with other elements in the water cooling loop.

Most 420 mm radiators have two to six G1/4 ports to connect them to the water cooling loop and twelve holes specifically designed for three 140 mm fans. Even with a 420 mm radiator, one should consider how many sources need to be cooled by a water cooler. If you are not using high-end components and multiple graphics cards, a smaller radiator that consumes less power is more worthwhile.

When purchasing a 420 mm radiator, it is essential to consider:

• Does the overall performance of the 420 mm radiator and fans match the components to be cooled?
• Is my case large enough for a water cooling loop with a 420 mm radiator?
• Is the material of the 420 mm radiator compatible with the other materials in the water cooling loop?
