The primary theoretical advantage explored in the video stems from the reduction of thermal interfaces between the heat-generating CPU die and the cooling liquid. In a conventional liquid cooling setup, heat must traverse from the CPU die to the IHS, then through a layer of thermal interface material (TIM) to the base of the water block, and finally into the coolant. By integrating the water block directly into the IHS, one entire thermal interface layer is eliminated.
This removal of a thermal interface leads to a lower overall thermal resistance (熱阻), which is explained in the video as being analogous to electrical resistance, hindering the flow of heat. By reducing the number of barriers to heat transfer, the total thermal resistance is decreased, theoretically allowing for more efficient heat dissipation away from the CPU die.
Furthermore, the modification results in a significantly shortened heat conduction path. The creator measured the distance from the CPU die to the coolant after carving the channels to be a mere 0.8 millimeters. This is considerably shorter than the combined thickness of the IHS (at least 2.65 millimeters) plus the base of a traditional water block (at least 1 millimeter), allowing heat to reach the coolant much more rapidly.
In practical testing conducted with an Intel Core i3-13100 CPU, the modified IHS, acting as a water block, demonstrated a 2 degrees Celsius lower temperature at maximum water flow when compared to a standard, off-the-shelf water block. Notably, the modified IHS also achieved comparable temperatures to the traditional water block even with a significantly reduced water flow rate, suggesting efficient heat transfer even under lower flow conditions.
While tests with a more power-hungry Intel Core i9-14900KS CPU yielded higher than anticipated temperatures, the video's creator posits that these results might be attributable to limitations in the initial water channel design and the resulting coolant flow. The overall conclusion presented in the video is that creating a water block by directly carving into the CPU's IHS presents a promising and potentially superior water cooling solution that could outperform many commercially available water blocks, especially with further optimization of the water channel design to maximize heat exchange efficiency. The video also highlights practical benefits such as easier installation without the need for motherboard modifications or concerns about cooler compatibility.
