Radian Heat Sinks

What Radian Heat Sinks does

Radian Thermal Products, Inc., operating commercially as Radian Heat Sinks, is a privately held custom and standard heatsink manufacturer founded in 1974 in Silicon Valley and headquartered at 2160 Walsh Avenue, Santa Clara, California. The company designs and produces thermal management solutions spanning vapor chamber heatsinks, heat-pipe integrated heatsinks, liquid cold plates, ultra-thin vapor chambers, and a full library of air-cooled heatsinks (extruded, die-cast, forged, skived, stamped fin, machined, plate fin, round pin, elliptical fin) in aluminum and copper, complemented by thermal interface materials and accessories. Its proprietary technology stack includes the VaporCore high-performance wick for vapor chambers and Micro Heat Pipes down to 0.6mm thickness with 3-5 second thermal response. Manufacturing is vertically integrated across four facilities: an ISO 9001:2015-certified and ITAR-compliant Santa Clara site (5-axis Matsuura MX-420, Hass UMCs, Zeiss CMM, automated pallet loaders), a Taiwan production facility, a China site, and a 25,000-square-meter Vietnam facility that became operational in 2024. Radian has identified target segments primarily in advanced microelectronics (microprocessors, GPUs, FPGAs, memory), with additional exposure to defense & aerospace (radar, communications, ITAR-controlled work) and data & telecoms (transceivers, co-packaged optics).

The business operates a hybrid commercial model. Custom heatsinks are sold through an engineering-led enterprise field sales motion — CAD, CFD, and FEA support, multi-year contracts, and direct engineering collaboration with buyers in target verticals — while standard catalog products (PCIe heatsinks, fansinks, push-pin and clip-on BGA heatsinks, accessories at unit prices of roughly $5-$40) are distributed through a direct e-commerce storefront on its website. Pricing for custom work is quote-based; standard products are unit-priced pay-as-you-go. Marketing is anchored by the company website, downloadable technical white papers on vapor chambers, liquid cooling, E-coating, and die-cast designs, plus LinkedIn/Facebook/X activity and trade publication placements. The company is owned under parent Intricast Co. with Thierry Sin serving as President and CEO since April 2017; named senior leadership includes Mong Hu (Board), Stuart Mitchell (Director of Sales and Marketing), and regional sales coverage in Canada (Jeff Canough) and the UK (Mark Willoughby). The company has been consistently profitable enough to self-fund a multi-country expansion without external venture or growth-equity capital.
