Thermal Resistance VS Sound Pressure Level

During our thermal resistance vs. sound pressure level test, we maintain a steady 100W thermal load and assess the overall performance of the coolers by taking multiple temperature and sound pressure level readings within the operating range of the stock cooling fans. The result is a graph that depicts the absolute thermal resistance of the cooler in comparison to the noise generated. For both the sound pressure level and absolute thermal resistance readings, lower figures are better.

This graph clearly reveals the strength of Corsair's H150i Pro RGB, which is the delivery of good thermal performance at very low noise levels. Coolers that match the noise levels of the H150i Pro RGB deliver significantly inferior thermal performance, whereas coolers that can offer the same levels of thermal performance are significantly louder. The only product that can match the thermal performance of the H150i Pro RGB at low noise levels is Alphacool's massive Cool Answer 360 kit, a much larger and greatly more expensive product. One can also notice that the H150i Pro RGB reacts poorly to high fan speeds, with the noise figures increasing significantly for a minimal impact on the cooler's thermal performance.

    How long are these tests run? Water takes time to stablize

    What I would love to see is a comparison of how much heat all these systems can dissipate, WHEN AT THE SAME NOISE LEVEL. For instance, if the AlphaCool had the same performance as the H150i, when it was dialed back to also give 39.2 dB, but then had the extra capacity if needed, it would be a no-brainer purchase.
