True to form, this low noise heatsink falls in with the crowd of other low noise heatsinks in this reference list, including the models from Verax, Zalman, Arctic Cooling, and others. We'll have to jump forward and see what the final rise above ambient temperatures look like before making a final decision on the heatsink.

The thermal test results speak volumes about the Spire SPA04B4 WhisperRock IV; the cooler is first and foremost a heatsink designed for low noise cooling. While I would have hoped for a slightly better set of thermal results from the SPA04B4, it is in line with other low noise heatsinks of similar acoustic output.

Given the close competition, it would be hard to decide on this model over one of the adjacent heatsinks that can offer slightly better cooling numbers, unless economics come into play. The Verax P14Cu is the prime example of this; while it is equally silent, it costs more than this Spire heatsink does.

In the end, the Spire SPA04B4 would make an acceptable low noise heatsink for a mainstream system where there is little if any gaming, or overclocking. There are other heatsink options which bring better thermals to the table, but most of those will also increase the noise levels slightly. When you shop for low noise heatsinks, the choice is often a complex mix of price, sound output and thermal performance, so study the results above before you make your decision.
