7. Watercool Passive cooler for VGA RAM (12 pack)
This set includes 8 passive heatsinks for the RAM modules of current graphics cards. The heatsinks are 5 mm high and feature a fin design that increases the surface area. They are made from black anodized aluminum. For easy installation, double-sided industrial-grade thermal pads are included. The heatsinks are intended solely for use on VGA RAM modules. Using them on other components, such as GPUs or voltage regulators, can irreparably damage the hardware and is done at your own risk! Please ensure that all residues of adhesive, thermal compounds, or similar materials are removed from the RAM modules before use. Failure to do so may affect the adhesive strength and/or duration, causing the heatsinks to fall off during operation! Ideal for use with the HEATKILLER® GPU-X³ Core series.

8. Watercool Heatkiller IV EBC
The Heatkiller IV EBC Backplate is a sensible addition for the graphics card coolers of the Heatkiller IV series. Mounted on the back of the graphics card, it enhances cooling performance and increases mechanical stability. This is made possible by the use of solid black anodized aluminum.
