PCIe Heatsink

A PCIe heatsink is specifically designed for a PCI Express (Peripheral Component Interconnect Express) card, which is a high-speed serial computer expansion bus standard. Format specifications are maintained and developed by the PCI-SIG (PCI Special Interest Group), a group of more than 900 companies that also maintain the conventional PCI specifications

As a PCIe card has a height restriction of 14.48mm this means that fin height is fairly limited for the PCIe heatsink, especially when considering that a typical BGA chip height is around 3mm including solder balls. 

Airflow should also be considered for a passive solution, and if there is a spare slot then it is worth considering our PCIe Fansink or BGA Fansink line.

Custom Heatsink

PCIe Heatsink examples

Heatsink for PCIe compute engine with a high capacity flash storage card

Scaleflux offers the ability to integrate compute engines with a high capacity Flash storage that is connected through PCIe. This innovative product dramatically increases the processing efficiency of compute-intensive functions. 

Through a consultative design process we were able to meet the demands of this tough thermal environment by manufacturing a clear anodized heatsink that includes extruding, die-casting, and silk screening processes.

Aluminum Plate Fin Heatsink for PCIE Card

Aluminum Plate Fin Heatsink for PCIe Card

Our customer was designing a PCIe Card and required a low-cost solution that would both cool their chip sets and provide mechanical support of their card.

Using advanced Mechanical Design Thermal Simulation technologies, Radian quickly designed a heatsink to meet the mechanical stresses and thermal management requirements of the application.  The end result is a low-cost aluminum plate fin heatsink with a milled baseplate to provide best thermal mating to the chip sets being cooled while providing appropriate clearance for all other supporting components.

Copper heatsink for PCIe Add-On card

Copper heatsink for PCIe Add-On card

Our customer was designing a high-end PCIe Add-On Card with a great deal of processing power and needed a low-profile thermal management solution with a low-profile to avoid conflict with other Add-On cards and not disrupt typical airflow from a wide array of possible installations.  We designed a one-piece copper heatsink that provided both thermal dissipation and mechanical support for the PCIe Card.

Dual Heatsink Solution for PCI Express Application

Dual Heatsink Solution for PCI Express Application

Customer had 3 chips on the board that needed heatsink cooling dissipating 26W. Customer had 300 LFM of airflow.

Using advanced thermal analysis we designed a low-cost aluminum heatsink solution.  We separated the heatsinks to minimize any bend, twist of the PCB. The Heatsinks are affixed with plastic pushpins.

PCIe Pushpin Heatsinks
