PRODUCT PICTORIAL AND WALKTHROUGH
The Hyper N620 looks great when released from the confines of the packaging. It has an aggressive stance without being overly tall. The smoky black fans contrast nicely with the aluminum fins and gray top cap. The N620 makes a great first impression, but we're all looking for performance in a high-end cooler like this. Let's explore some of the design elements to see if we can discover what makes the Hyper tick.
From the top, we can see that the fans are not exactly opposite of one another. This allows the cooler to be a bit wider, offering more finned area per heatpipe while keeping the height to a minimum. In the above photo you can see two of the six heatpipes emerging from the top shroud. The remaining ‘pipes can be seen peeking out from under the shroud.
From the side, we can see that Cooler Master has closed off half of the fin width while the rest is open to the sides. I'm not quite sure why, but with one fan pushing and the other pulling air through the cooler, one would think that fully closed sides would promote the best flow. The fan mounting is also a bit puzzling. As you can see, the bottom fan mounts are a rubber-like material used to minimize vibration noise in applications such as this. However, the fan is secured with screws at the top, effectively negating any benefit that the bottom mounts might provide.
The base and 6mm heatpipes are of copper construction and there is evidence of either solder or thermal interface material between the two. Cooler Master's unique heatpipe arrangement has the outside two ‘pipes running only from the base to the top of the cooler. These are the visible ones we observed in the top view. The other four ‘pipes are U shaped, effectively making the design a ten pipe arrangement. Don't forget to remove the protective plastic sheet, or you'll be very disappointed in the cooling performance.
The base lacks the mirror finish that we see on some coolers, but it's very flat and perfectly serviceable. This photo also illustrates the clever heatpipe/fin/fan arrangement that I hope will yield some outstanding cooling.
