Modder transforms the Intel i9-14900KS CPU’s IHS into a direct-die water block

A modder has transformed the integrated heatspreader (IHS) of an Intel i9-14900KS CPU into a direct-die water block, advancing the concept of direct-die CPU cooling. This modification was brought to light by @Unikoshardware on Twitter/X, showcasing the innovative design of this custom CPU cooler.

Rather than swapping out the stock IHS for a direct-die water block, this modder has ingeniously converted the IHS of their CPU into a water block. This transformation utilized a CNC machine to carve channels into the IHS, while a custom gasket and cover plate were created to ensure the new water block was watertight.

During testing, this unique water block demonstrated improved cooling efficiency compared to a conventional CPU water block due to the reduced distance from the CPU (the heat source) to the coolant. However, reducing the pump speed caused the temperatures to escalate more quickly than with a standard water block, leading to better thermal performance with standard blocks at lower pump speeds.

Evidently, this custom water block design lacks the optimization seen in dedicated CPU water blocks, resulting in increased flow resistance. Nonetheless, there’s potential for a more refined CPU IHS water block design to be developed in the future.

While this personalized liquid cooling solution is intriguing, it may not be sustainable as a long-term water block. It's likely that Intel did not design their CPU IHS with liquid cooling in mind. Additionally, the CNC machining process has stripped away the protective layer of the IHS, raising concerns about corrosion if this block is used over an extended period. Nonetheless, it's impressive to see PC enthusiasts exploring innovative and distinctive concepts.
