Corsair H90 & H110 Liquid CPU Coolers Performance Review

The Corsair H90 and H110 are positioned as high surface area, 140 mm radiator liquid CPU coolers, and this review breaks down how their design choices translate into real-world cooling performance. The host explains that the H90 uses a dense fin arrangement and a thicker radiator to gain surface area, while the H110 follows the same principle on a larger scale with dual 140 mm radiators. To ensure a fair comparison, the testing uses standardized Noctua fans (NF-F12 PWM and NF-A14 FLX) at around 1000 RPM, rather than the stock fans included with the coolers, so the results reflect the capabilities of the coolers themselves rather than the fan housings. The testing setup includes a 3930K overclocked and overvolted CPU and a GTX 580 GPU, with a Furmark-like load simulation that mimics a hot-case environment to reflect real-world conditions. Ambient temperature is monitored with a HH 506 RA multilogger so results can be corrected to a 20°C baseline for consistency across different runs and setups. The host also notes the H110 is the highest performing cooler in their test, with the H90 providing a solid, competitive showing, and the H110 outperforming the H100i by several degrees in a six-core configuration, indicating that larger radiators and higher surface area can yield noticeable gains under load. The walkthrough ties the measured performance to practical takeaways for potential buyers, including how the charts are maintained and updated on a master testing chart that users can download for ongoing comparisons. Overall, the review presents a rigorous, repeatable methodology and clear conclusions: the H110 leads the pack among Corsair’s 140 mm offerings in this setup, the H90 remains a strong alternative with only a modest gap to the H100i, and the tested configuration emphasizes the importance of standardized fans to reveal true cooler performance. The presenter also invites viewers to download the master chart and stay engaged for future updates, highlighting the ongoing nature of performance comparisons in PC cooling.
