Radiator and Fans

The biggest component of this system is the radiator with preinstalled fans. Swiftech H₂0-220 Apex Ultra+ uses MCR220-QP copper radiator:

Without the fans the radiator measures 284.5 x 128 x 34 mm and holds 500ml of fluid.

It comes with two 120-mm fans already preinstalled. One of the fans has a mounted plastic retention frame for attaching the entire block to the system case rear panel:

The radiator has small-cell corrugated internal structure:

There are two fittings with 10mm internal diameter already attached to its lower side:

It is topped with two Chinese fans without any specific design peculiarities:

According to the marking on the rotor, these are RDM1225S fans using a slide bearing. Each fan should consume maximum 2.76W of power:

They rotate at 2000RPM maximum speed and generate 36dBA of noise creating 162.6CFM joint airflow. However, Swiftech H₂0-220 Apex Ultra+ comes bundled with two adapters: a 7V one and a 5V one. In the latter case the fan rotation speed drops to ~900RPM at 21dBA noise level. In this case the fans are really quiet. By the way, you can install fans onto both sides of the radiator if you remove the protective wire grills first.
