There are many types of CPU cooling and I thought I'd cover them to outline the benefits and advantages of each. Passive heat sinks are used on older CPUs and not relevant to today's discussion as they can't cope with the heat demands of the modern processor. The modern retail CPU comes with a heatsink and fan assembly that can efficiently cool the processor.
The modern Water cooling system can be a complicated affair. Tubing, the reservoir for excess fluid and the water cooling block can make a cool running system, but installation and space considerations can make it a daunting challenge for the uninitiated. That's where a self-contained liquid cooling system like the CoolIT Domino Advanced Liquid Cooling System comes in.
