Intel Nova Lake: New Cooling Methods for CPUs

Intel has introduced a fundamental redesign of its processors with the Nova Lake architecture (Core Ultra Series 4) on the LGA 1954 socket. Instead of a single large chip, multiple smaller components, known as tiles, are now utilized. This distributed architecture means that heat no longer accumulates centrally under the heat spreader, but rather at various hotspots, presenting new challenges for cooling. The new design of the Nova Lake architecture has significant implications for heat generation. In particular, the up to 16 performance cores and the new bLLC (Big Last Level Cache) generate localized high temperatures.

These hotspots necessitate an adapted cooling technique to prevent overheating and consequent throttling. To effectively cool the processors, Intel recommends using coolers with an offset mounting kit. These special mounts allow the heatsink to be shifted by a few millimeters, ensuring that the base plate sits directly over the heat-intensive compute tiles. Manufacturers like Noctua already offer such solutions that can significantly enhance cooling performance. The temperature reduction achieved by offset mounting the coolers can lower temperatures by up to 5 degrees Celsius under full load.

This is particularly important as the Nova Lake processors can reach peak performance levels of up to 700 watts in the so-called PL4 state. Effective cooling is therefore crucial for stable operation. Another important aspect of installation is the correct application of thermal paste. Due to the tile structure, a single blob in the center is no longer sufficient. Instead, the paste should be spread thinly and evenly across the entire heat spreader to ensure that all underlying components have optimal contact with the cooler.

In the BIOS, the power limits "PL1" and "PL2" should be manually set to the manufacturer's values of 125 watts and 250 watts. Many motherboards leave these values unlimited by default, which can lead to unnecessary overheating. Correctly setting these limits is essential to maximize processor performance while keeping temperatures within a safe range. The distributed arrangement of the tiles not only affects cooling but also the overall performance of the processors. Without adequate cooling, the processor can overheat and throttle performance, resulting in a noticeable loss of capability.

Users should therefore ensure that their cooling systems meet the new requirements. The Nova Lake architecture represents a significant advancement in Intel's CPU design. The new cooling methods are crucial not only for performance but also for the longevity of the processors. Intel has already announced that further optimizations are expected in future architectures. The Nova Lake processors have been available on the market since November 2, 2026, offering a range of improvements over previous models.
