Heat is the enemy of all computer components, but it can take a particular toll on the CPU. Central processing units can generate better clock speeds when they're able to tolerate higher voltages, but the very electricity that allows them to run also generates a tremendous amount of heat, which can damage the components of the chipset if left unchecked. Most modern CPUs will actually throttle their own performance in order to keep this from happening. That's why having a quality CPU cooler is so important. By keeping your CPU cool, you are allowing it to operate at the peak of its capabilities without wearing out too quickly.

A lot of modern CPU coolers come with LCD screens attached. These can be used to monitor temperatures and ensure that the CPU is operating correctly but many of them also add some aesthetic value, allowing you to showcase a logo or play tiny animations. These are available on both air and water-cooled units. It probably isn't a good idea to sacrifice cooling performance for the sake of a screen, but there are plenty of coolers out there that offer excellent cooling capabilities and the added versatility that comes with having an LCD screen attached. One of the best ways to find the highest quality coolers available is to compare the specs from the models offered by top brands and check what reviewers have to say about real-world performance.
