Design and Functionality

The Swiftech H220 is a closed-loop liquid cooling system which comes filled with coolant and ready to work. Like most serially manufactured systems of its kind, it consists of a radiator with fans, a pump/waterblock combo, and two pipes connecting these components.

Having a huge number of liquid cooling components of any class at its disposal, Swiftech went the simplest way and just built the H220 out of existing products.

The system is based on the 240mm MCR-X20 Drive Rev3 radiator.

Its total thickness is 29 mm but its body is 24.5 mm thick.

The radiator's dimensions are detailed in the following picture:


The key difference from radiators of other inexpensive products is the material. While liquid cooling systems from Corsair, Zalman and Thermaltake use aluminum radiators, Swiftech offers a copper one.

There is no doubt about that. First of all, it is heavy. And secondly, you can see the perforated copper ribbon easily with a naked eye.

The radiator has 12 flat pipes with coolant. A perforated corrugated copper ribbon is soldered in between the pipes. So, it's a classic solution but the superior material must be noted.

Two rotating 10mm fittings go out of one side of the radiator. Pipes with an outer diameter of 16 mm are secured on them with screw clamps.

The pipes are soft and flexible but thick enough to avoid bending and stopping the flow of coolant. They are 405 mm long.

On the other side of the radiator there is a small expansion tank with a stopper.

Thus, unlike the other compact liquid cooling systems, the Swiftech H220 is serviceable. You can add more coolant and include additional components into it since the pipes are not press-fitted but secured with clamps. That's an important advantage.

Now let’s check out the pump and waterblock. The pump is the PWM-regulated MCP350 model we’ve already met with in our reviews whereas the latter is an excellent copper waterblock Apogee XT that features a microchannel structure.


The pump is installed above the waterblock from which both fittings stick out. Unfortunately, the Swiftech H220 specs do not mention the pump’s performance (only its speed: from 1200 to 3000 RPM with PWM-based regulation) but we suppose that it is 440 liters per hour as specified for the original MPC350. The pump’s ceramic bearing is expected to serve for at least 60,000 hours while its peak power consumption is 6 watts.


The pump is connected to the mainboard with a 4-wire 290mm sleeved cable. This component measures 62x62x56 mm.

We already examined the Apogee XT waterblock in an earlier review and it is unchanged in the H220. It still has a microchannel structure and a perfectly finished base:

The thermal grease imprint on our CPU wasn’t perfect, though:

It’s because our CPU has a convex heat-spreader. Anyway, this doesn’t affect the cooler’s performance much as you will see in our tests. We can add that the waterblock’s fittings can be turned around as well, making it easier to install it on a CPU.

The Swiftech H220’s radiator carries two 120mm Helix 120 PWM fans we tested before.

Their rotation speed is PWM-regulated within a range of 800 to 1800 RPM. The air flow varies from 24 to 55 CFM, the static pressure from 0.53 to 2.29 mm of water, and the noise from 16 to 33 dBA. The improved sleeve bearing has a specified service life of 60,000 hours. The fans’ 4-wire sleeved cables are 395 mm long.
