Corsair H100 vs H100i Performance Test Linus Tech Tips

In this Linus Tech Tips comparison, the host presents a structured test between the Corsair H100 and the newer H100i liquid cooling solutions. He builds a compact test bench with a GTX 580, X79, a 3960x or 3930k, and a solid case to simulate a realistic gaming PC environment. The video walking through methodology is explicit: both coolers run in stock configurations using the original H100 fans and the updated H100i fans, with attention to static pressure ratings and tubing diameter. He emphasizes that the radiator surface area remains a common constraint and why improved fans and firmware can influence the perceived improvements. The host outlines his approach to data collection, including turning up the CPU voltage to stress the coolers and correcting measurements to a standardized room temperature baseline, so results are comparable for average home setups. He also details how he will capture idle and load temps, using a mix of real temp GT readings and prime95 stress to generate meaningful load on both the CPU and GPU. Overall, the setup aims to reflect a typical closed-case, well-ventilated system to approximate real-world performance rather than an open bench scenario. The narrative culminates in a practical takeaway that the H100i offers meaningful improvements mainly through better fans and Corsair Link software, while the radiator area ultimately caps the thermal headroom for these coolers.
