The Cooler Master Hyper 612 PWM features a 120mm PWM fan with support for an additional fan, 6 copper heatpipes and a very large heatsink for maximum heat disbursement. The cooler isn’t anything fancy in terms of aesthetics, except for the black cover on the top of the heatsink which has an embossed Cooler Master logo.
The fan itself is a 120mm PWM fan which has a speed range of 600-2000 RPM and puts out 34.9-82.9 CFM. The fins on the fan aren’t your typical slightly curved fin, but rather an almost wavy fin. If you were to remove the black cover on top of the heatsink it would reveal the five cutouts, which extend all the way down the heatsink, on each fin. According to Cooler Master the cutouts are resistance reducing and reduce weight and improve cooling performance.
Like I mentioned before, the heatsink is very wide. The heatsink alone is even larger than some other coolers, even including the fan. With the addition of the fan it makes the cooler about 5.5 inches wide. Adding another fan could increase cooling, but I think would cause more clearance issues when it’s installed.
The six copper heatpipes are evenly spread throughout the heatsink and form into the base in what Cooler Master calls, cross the CPU “hot zones”. Another mini heatsink is found on top of the base and also supports the larger heatsink which the heatpipes are embedded.
The copper base has an almost sticky finish to it; I’m pretty sure it was due to the residue from the protective sticker melting. I think if it wasn’t so sticky you would be able to see a high gloss finish. I’d also have to assume this is an isolated incident, but perhaps Cooler Master should check into this.
