Thermalright

From compact units that fit in the tightest confines to larger towers that offer better CPU temperatures and reduced noise, there is a broad range of air coolers to choose from. Given the diversity, the air coolers here have at least one thing in common - they are all compatible with AMD CPUs.

As always, check that your chosen cooler is compatible with your specific CPUs socket, that it won't interfere with other components on your motherboard like RAM or heatsinks and that it will fit inside your case.

Accessories for computer cases. These includes riser cards, various plates and panels.

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.

VGA coolers are the best way to cool your Graphics card when overclocking. This prevents damage to your components and can also decrease fan noise on certain graphics cards. Updated

These air coolers are the most compact around, and are ideal for systems where space is at a premium, such as with mini-ITX builds or Home-Theatre PCs (HTPCs). Given that these coolers prioritise small size over performance, most are not suitable for high-end, overclocked CPUs.

Ensure you check that your selected cooler offers the cooling performance necessary to cool your processor, and whilst most provide multi-socket support, as always, check that your motherboard socket is supported.

Chipset coolers are the best way to cool your motherboard chipsets when overclocking. This prevents damage to your components and can also decrease fan noise.

Thermal paste is used to create a heat conducting medium between your heatsink and processor/chip. This aids in the maximum possible heat transfer away from your chip and into the heat sink. Allowing your chip to run as cool as possible and hence allows your heat sink to do what it is meant to do.
