Thermalright

Not all coolers fit all of Intel and AMD's processor sockets, so these kits can be used to make a heatsink work with a previously-unsupported motherboard. This category also includes spare screws, fan attachment brackets and other accessories for popular coolers - perfect if you've lost a crucial component.

Third-party coolers are to replace the standard cooler on your graphics card when overclocking. This may prevent damage to the components and can also decrease fan noise on certain graphics cards.
