Particularly for inexperienced PC builders, cooling solutions are often an afterthought. Many PC cases ship with front and rear fans already installed and some Intel and AMD CPUs come with stock heat sinks in their retail boxes. In reality, this cooling hardware combination is sufficient for most low-end and mid-range gaming PCs. However, if users want to push the limits of their new system and overclock components like processors and graphics cards, heat can quickly build to levels ordinary fans can’t handle. Since CPUs usually generate the most heat in a PC case, typical cooling solutions attempt to dissipate the extra heat emanating from overstressed processors.
