Testing Results, Maximum Fan Speed (12 Volts)

The first round of testing takes place with the supply voltage of the fans and pumps at 12V. This should depict the maximum possible performance of each cooler without any modifications.

From the above charts, we can see that the Reserator 3 Max Dual has different behavior than many of the other coolers. Zalman's cooler behaves extremely well when the load is low, easily claiming the top spot of our thermal performance charts and outperforming even the larger 280 mm radiator designs. However, the performance of the Reserator 3 Max Dual decreases as the load increases and it can't really keep up with the competition at very high loads. The end result is a middling, unsurprising average thermal resistance. The sound pressure of Zalman's 120 mm LED fans at maximum speed is an ear-bursting 51.5 dB(A) as well, though that's no surprise considering the specifications.

    "Although we cannot fully explain why, it seems that the Reserator 3 Max Dual cannot dissipate high quantities of thermal energy quickly enough."

    Could it be something to do with the overlapping cooling path?

    Although I cannot really calculate it, I believe that the surface of the pipes is simply much smaller than the surface of a classic two-pass radiator. Therefore, even though it can dissipate heat very quickly via its sizable fin area, the surface between the array and the tubing is not sufficient to maintain a very large energy transfer.

    This simply is an assumption on my part and is not based on any form of evidence.
