| Device | |||
| Your choices are... | |||
| Passive Heat Sink | Heat sinks are thermally conductive, usually metallic components that are attached to electronic devices in order to absorb and dissipate the heat generated by the electronics. Surface area maximization and thermal conductance are important considerations in heat sink design. A wide variety of cooling fin configurations and geometries are used. | ||
| Active Heat Sink | Active heat sinks (CPU coolers, fan sinks) are heat sinks that include an integrated fan. Fan airflow geometry and heat sink fin direction are designed together. Sometimes, active heat sinks are designed for specific processors or overclocking parameters. | ||
| Liquid Cooler/Cold Plate | Liquid coolers/ cold plates use a liquid medium such as water or liquid nitrogen to remove heat from components. | ||
| Thermo-Electric Cooler | Thermo-electric coolers use an electric element to pump heat from the element’s hot side to its cool side. In turn, these devices transfer heat from the component to the environment. | ||
| Vapor Cooler | Vapor coolers or phase change coolers are similar to air conditioning or refrigeration systems, but evaporate a refrigerant in a small block mounted directly on the component. | ||
| Other | Other proprietary, specialized or unlisted devices. | ||

Footprint and Type

| |||
| Width | The width is the footprint's shorter dimension. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Height | The height or depth includes all mounting features and, in the case of active heat sinks, the integral fan. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

| |||
| Heat Sink Fin Style | |||
| Your choices are... | |||
| Round Pin | Round pins are cooling fins that extend from the base. This fin style offers a high surface area to weight ratio and provides multiple airflow paths through the fins. | ||
| Elliptical Fin | Elliptical fins are similar to pins and shaped elliptically to provide good airflow characteristics. | ||
| Straight Fin | Straight fins typically extend across the length of the heat sink. This very common and versatile design uses extrusion to produce fins. Extrusion shapes can be very complex in order to maximize the heat dissipation surface area. | ||
| Stamped Metal | Stamped metal heat sinks are manufactured in standard configurations, and according to application-specific geometry and thickness requirements. | ||
| Machined Plate | Machined plate heat sinks conform to exact tolerances and are free of burrs and other irregularities. | ||
| Other | Other unlisted, specialized, or proprietary heat sink fin style. | ||

| |||
| Mounting | |||
| Your choices are... | |||
| Mounting Legs | Integral mounting legs usually have standard hole spacing and provisions for offsets and clearance. | ||
| Mounting Holes | Heat sinks attach to components through mounting holes such as through-holes and threaded holes. | ||
| Adhesive / Tape | Heat sinks are mounted with engineered tapes and adhesives that have a high thermal conductance. This eliminates the need for mounting holes and hardware. | ||
| Clips | Mounting clips are used to attach heat sinks directly to electronic components such as processors. | ||
| Socket Mount | Heat sinks mounted directly in PC sockets. | ||
| Other | Other unlisted mounting configurations. | ||

|
| ||
| Thermal Resistance | Thermal resistance or thermal sensitivity, the central performance specification for heat sinks, is typically expressed in Celsius (°C) as the temperature increase per watt of heat handled. For catalog and comparison ratings, thermal resistance is a nominal specification. Factors that affect this specification include increased airflow, water-cooling, and ambient temperatures. Frequently, thermal resistance is presented as a performance curve. | ||

| Material | |||
| Your choices are... | |||
| Aluminum | Aluminum is a very common heat sink material. It has good thermal conductance and is easily extruded, stamped, and machined, with low weight and good finish characteristics. | ||
| Copper | Copper, an excellent thermal conductor with good mechanical properties, is used in premium heat dissipation products. | ||
| Steel | Steel has very good thermal conductivity and is heavier than other heat sink materials. This category includes all grades of steel and stainless steel. | ||
| Mixed Material | Mixed materials combine components such as copper plates and aluminum fins. Often, mixed materials are used to optimize the combination of performance and cost. | ||
| Other Materials | Other unlisted, specialized, or proprietary heat sink materials. | ||
