Design and Functionality

The “SE” (Second Edition) version differs from SI-128 even less than Ultra-120 A from Ultra-120 eXtreme. To be more exact, we found only three differences. We are going to dwell on them a little later and now let’s recall what this cooler looks like:

The heatsink measures 125 x 145 x 91.5mm and weighs 510g. Four copper heatpipes 8mm in diameter come out of the copper base. They hold an array of 78 thin aluminum plates resting on two wire stands on the other side:

The plates are ~0.25mm thick and are spaced out at about ~1.3mm. The calculated heatsink effective surface area is ~6786sq.cm. The entire cooler is nickel-plated:

 

The first distinguishing feature of the new SI-128 is the perforated heatsink plates:
