Thermalright today introduced the SI-100, a C-type aluminium fin-stack CPU cooler. This appears to have a thicker fin-stack than the company's AXP-100-series coolers. Its design involves a nickel-plated C1100 copper base, from which six 6 mm-thick nickel-plated copper heat pipes emerge, conveying heat through a fin-stack that propagates along the plane of the motherboard. This fin-stack is ventilated by an included 120 mm TL-E12 fan. The fan features fluid-dynamic bearing, and has a top speed of 2,000 RPM, pushing up to 72.37 CFM of airflow, with 2.87 mm H₂O static pressure, and noise output of 27.7 dBA. With its fan in place, the cooler measures 120 mm x 120 mm x 99.8 mm (WxDxH), weighing 640 g. Among the CPU socket types supported are AM5/AM4, LGA1700, and LGA1200/LGA115x. The company didn't reveal pricing.
