A Closer Look
Even at first glance, the Cooler Master Hyper N620 isn’t a typically-styled tower CPU cooler. The offset fan looks odd from the front, further investigation is needed to see the purpose in it.
Looking from above, we see that the radiator is much larger than the typical 120mm tower cooler, and the fans are offset in opposite directions to provide airflow to the entire radiator. The typical 120mm radiator is just over 4″ wide, the N620’s radiator well over 1″ wider than that.
The radiator itself is fairly typical of higher end air coolers, consisting of stacked crimped aluminum fins. The fins are a little closer together than cheaper coolers allowing for more fins in the same overall height, greatly increasing the overall radiator cooling area. The cooler is just shy of two pounds, which puts it in the same weight class as most higher-end tower coolers.
The fans are high-efficiency fans with lots of curved blades. One feature that I really like is that the fans are powered by one PWM connector. The last cooler I reviewed with twin fans had two fan connectors. That’s ok if you don’t use the motherboard’s fan connectors to power your chassis fans, but could cause a problem if you do, especially with a motherboard that only has a couple of chassis fan headers.
The large radiator helps to accommodate the six.yes six.6mm heatpipes. There is just so much heat you can transfer with a 120mm radiator so the larger size is definitely required to dissipate the heat transferred by the extra pipe(s). CM has polished these copper pipes to a dazzling finish.
The base is combination aluminum/copper. The aluminum top helps to shave some weight and cost compared to a solid chunk of copper, the copper bottom provides copper’s superior heat transfer from the CPU to the heatpipes.
The base itself has also been buffed to a high shine. Not the lapped mirror finish that some people require, but it is among the shiniest finished bases I have seen in quite a while.
Included is a tube of Cooler Master’s ThermalFusion 400 thermal compound, and hardware to accommodate Intel LGA 1366/775, and AMD Socket AM3/AM2/939/754.
