This bundle includes the Alphacool Core 1 CPU Water Block and the Thermal Grizzly 1851 CPU Contact Frame. With the Core 1, Alphacool presents a new generation of CPU water cooling. The latest desktop processors are constantly becoming more powerful, but they also produce more and more waste heat. The Core 1 reliably solves this problem with the help of its completely newly developed 3D jet plate, which is also used in industry. The CPU water cooler, made entirely of metal, not only impresses with its elegant appearance, but also has a new mounting system that simplifies installation. Compatibility: Intel: LGA 1700 / 1851 AMD: AM4 / AM5 Technical specifications Dimensions: (L x W x H) 72 x 72 x 26.50mm Material cooler: nickel-plated copper Material housing: Brass Material connections: nickel plated brass Connections: 2 x G1/4" The Intel 1851 CPU Contact Frame V1 is the version of the well-known mounting aid tailored to Intel motherboards with the LGA1851 socket. By using the Intel 1851 CPU Contact Frame V1, the concave bending of the CPU's Integrated Heat Spreader (IHS) caused by the standard Integrated Loading Mechanism (ILM) is avoided. This results in better contact between the CPU cooler and the IHS, improving cooling performance. The Intel 1851 CPU Contact Frame V1 is compatible with Intel Core Ultra 200 Series processors for the LGA1851 socket. Additionally, the frame is compatible with CPUs whose Integrated Heat Spreader (IHS) has been sanded down by no more than 0.2 millimeters. Care must be taken during installation to ensure no electronic components are located under the frame, especially with Mini-ITX form factor motherboards. Removing the Integrated Loading Mechanism (ILM) from the motherboard may void the manufacturer's warranty for the motherboard!
