This bundle includes the HEATKILLER IV PRO CPU Water Block and Thermal Grizzly AM5 contact frame. Water coolers from the HEATKILLER CPU series are among the most popular and top-selling CPU water coolers. Ever since the launch of the first HEATKILLER CPU water cooler in 2001, the series has been constantly improved and optimised. The HEATKILLER IV presents the most extensive alterations, so far.

As a Contact Frame, the AM5 Contact & Sealing Frame creates optimal contact pressure of the CPU into the socket, while an optional, included inlay made of silicone foam serves to protect the exposed components on the CPU. Innovative Silicone Foam Inlay for Protection and Sealing The AM5 Contact & Sealing Frame comes with a silicone foam inlay. This can be placed on the PCB of the processor, similar to the AMD Ryzen 7000 CPU Guard. When installing the AM5 Contact & Sealing Frame, the gap between the heatspreader and the aluminium frame is sealed by the silicone foam by pressing the foam onto the PCB. This prevents thermal paste or liquid metal from getting onto the CPU's unprotected components. The foam inlay is optional when used with thermal pastes, but mandatory when used with liquid metal.
