Device
   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       Liquid coolers 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.       
   Cold Plate       A cold plate is a thermal device that provides heat transfer.  Some cold plates use liquid cooling and have tubes that pass through the plate, while others are a solid metal plate that acts as a heat interface. 
   Other       Other proprietary, specialized or unlisted devices.

   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. 
   Folded Fin       Folded fin heat sinks include a continuous strip of convoluted or corrugated sheet metal stamping that is formed to a specified height. 
   Bonded Fin       Bonded fin heat sinks include a stamped or pre-fabricated plate bonded to a channel on a heat sink base plate. 
   Heat Pipes       Heat pipes are evacuated vessels, typically with circular cross sections, that are back-filled with a small quantity of working fluid. These completely passive devices are used to transfer heat from components to heat sinks. 
   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. 
   Integral Locking Mechanisms       Heat sinks include integral locking mechanisms that mechanically attach the heat sink to the electronic component. 
   Other       Other unlisted mounting configurations.

Specifications
   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. 
   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.
   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.
