120mm Aluminium CPU Heatsink This is a 120mm Long Aluminium Water Cooling Block Liquid Cooler Waterblock Radiator-GPU CPU Cooling Heatsink.  The CPU heatsink has a solid construction and choosing aluminum as the raw material is a wise option for heat dissipation. It is ideal for applications in computer CPU, industrial inverter driver, laser head cooling, and industrial control cabinet cooling. The CPU heatsink is a water cooling block where the heat dissipation method os that the liquid conducts the cold and heat exchange. A water cooling block is the water cooling equivalent of a heat sink. It can be used on many different computer components, including the central processing unit (CPU), GPU, PPU, Peltier Module, and Northbridge chipset on the motherboard. Aluminum Water Cooling Block 40×120 is meant to transfer heat from one source into the liquid that flows around the water cooling block. Removing the heat from the graphic card into the liquid that runs through the water cooling block. There are two main types of GPU water blocks: full cover blocks and universal blocks for custom graphic cards Aluminum Water Cooling Block 40×120 is the best way to cool a CPU because water transfers heat much more efficiently than air. Liquid cooling also makes your PC run quieter because you won’t have fans constantly running at a high RPM. However, liquid cooling a PC can also be dangerous if water leaks onto hardware. Features: Material: Made of high-quality aluminum for excellent heat dissipation. Size: Measures 120mm, suitable for various CPU cooling applications. Compatibility: Compatible with a wide range of CPU sockets, including Intel and AMD platforms. Cooling Method: Typically used in conjunction with a fan to enhance cooling efficiency. Durability: Constructed to withstand high temperatures and provide long-lasting performance. Lightweight: Aluminum construction makes it lightweight and easy to install. Efficient Heat Transfer: Designed to maximize heat transfer from the CPU to the heatsink. Applications: Computer CPU water Industrial inverter driver Laser head cooling Industrial control cabinet cooling
