The small heatsinks are a perfect addition for cooling various electronic components, such as the VRAM of a graphics card, voltage regulators on motherboards, or even in an amplifier or RC vehicles. For maximum thermal capacity and cooling performance, the coolers are made of copper. The well-known greenish discoloration of copper is largely prevented by Alphacool through a coating. This increases the lifespan of the coolers and ensures consistent cooling performance. The coolers can be attached to the desired components using optional thermal adhesive or self-adhesive thermal pads. Technical specifications: Dimensions: 10 x 10 mm, Material: solid copper. Package contents: Alphacool GPU RAM Copper Heatsinks 10x10 mm - 10 pieces.
