WHAT IS A PCIe FANSINK?

A PCIe Fansink 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.

Radian offers both standard and custom versions of PCIe Fansinks. If the standard models do not fit your application, please contact us for a custom quote.

PCIe Fansinks

As a PCIe fansink manufacturer, we specialize in designing and producing high-quality cooling solutions for computer hardware. Our fan sinks are designed to fit onto PCIe cards and provide efficient cooling to prevent overheating and ensure optimal performance. 

The SubZero and Scorpion Series fansinks have been specifically designed and tested on a variety of PCI card applications, but are ideal for other low profile applications. The fansink has been modeled for use with pushpins, but can be used with screws. For exact details on a particular PCIe fansink, please contact us for more information.

Low Profile Heatsink

If you’re looking for a solution to keep your electronic devices cool without taking up too much space, then a low-profile heatsink might be just what you need. A low-profile heatsink can effectively dissipate heat while maintaining a compact design, whether working with a small form factor computer or a compact electronic device.

One of the main advantages of a low-profile heatsink is its compact size. Traditional heatsinks can be bulky and take up much space, making it challenging to fit them into tight spaces. However, with a low-profile heatsink, you can enjoy efficient heat dissipation while saving valuable space. This makes it ideal for small form factor PCs, gaming consoles, laptops, and other electronic devices where space is limited.

Efficient heat dissipation is crucial for the longevity and performance of electronic devices. Excessive heat can lead to thermal throttling, reduced lifespan, and even system failure. A low-profile heatsink effectively absorbs and disperses heat away from the components, preventing them from overheating. This ensures optimal performance and extends the lifespan of your electronic devices.

When choosing a low-profile heatsink, it’s essential to consider the material and design. Aluminum is commonly used in heatsinks due to its excellent heat conductivity and lightweight properties. Additionally, some low-profile heatsinks feature heat pipes or fins to enhance heat dissipation further. These features maximize the cooling efficiency of the heatsink, ensuring that your electronic devices stay cool even under heavy loads.

We offer a wide range of low-profile heatsinks with different sizes, materials, and thermal performance to meet our customers’ needs. Whether you are designing a small electronic device or a complex industrial system, our low-profile heatsinks can help ensure optimal thermal management and enhance your products’ overall performance and reliability.

Sub Zero Fans with Label

SubZero Series

The SubZero series are low profile Fansinks made from extruded Aluminum and anodized blue. Two standard sizes are available with options for 5V or 12V fans. Pushpins are available in Plastic or Brass. As an extrusion, the SubZero series can be modified to increase the length of the PCIe fansink. Please contact us for a custom quote.
