Know before you buy
No, this is a passive cooler designed specifically for silent operation without the need for active airflow from a fan. It relies entirely on its 27 cooling fins and natural convection to dissipate heat.
You can, but you must ensure the cooler does not come into direct contact with any voltage sources or live electrical contacts. Because it is made of conductive aluminium, it could cause a short circuit if it touches electrical pathways.
The 6.2mm base provides a solid, stable foundation that facilitates rapid heat transfer from the component into the cooling fins. This thickness ensures the heat is effectively spread across the entire surface area of the cooler.
Yes, its lightweight 700g aluminium construction makes it an excellent choice for weight-sensitive applications or environments where heavy cooling solutions might put unnecessary stress on mounting points.
The cooler does not come with pre-drilled mounting holes or adhesive. You will need to use thermal adhesive, thermal pads, or a custom mechanical mounting bracket to ensure a secure, thermally conductive connection to your component.
