Introduction and Technical Specifications

Introduction

The latest rage in CPU cooling seems to be the self-contained water cooler because of the cooling potential of these coolers without the noise of a comparable air-based cooling system. This is something that cooling enthusiasts have known for years with the custom water cooling solution heat dissipation capacity only rivaled by its varied composition. A typical custom water loop is comprised of a pump, CPU cooling block, and a radiator in its simplest form.

Today, we are looking at the impact of the radiator on the custom water cooling loop, specifically the affects of radiator thickness and fin density on the cooling efficiency of the cooling loop. For this testing, we are comparing a single Swiftech MCR 320-QP Radiator, dual Swiftech MCR 320-QP Radiators in series, and an XSPC RX360 radiator while keeping the pump, CPU cooling block, and coolant used constant between tests.

Both radiators used in this comparison are in a 3 x 120mm form factor, supporting up to six total 120mm fans in a push / pull configuration. The Swiftech MCR 320-QP radiator is approximately half the thickness of the XSPC RX360 radiator, but has 150% more surface fin density (measured in fpi (fins per inch)). A thicker radiator can handle more coolant as well as spreading the coolant over a larger surface volume for cooling capacity, while a higher fin density allow for more effective heat dissipation via the cooling fans. However, there are negatives of each. A thicker radiator can inhibit coolant flow speed because of its larger capacity and and surface volume. On the other hand, higher fin density requires a higher CFM rated fan to effectively pass air through the radiator effectively.
