According to Cooler Master engineers, CDC technology guarantees 5% lower temperatures and 6% larger contact surface. Moreover, they also managed to provide very decent finish of the base surface:

…and to maintain ideal evenness of the base (the thermal paste imprint is uneven, because the processor heat-spreader is slightly convex): 


Well, that’s pretty much all we could tell you about the heatsink of the Cooler Master Hyper PWM 412 cooler. As for the fan, we are already well familiar with it – it is a 120 mm XtraFlo fan with a clear seven-blade impeller:


The fan rotation speed may be adjusted automatically using PWM method in the interval from 600 to 2000 RPM. It will create 24.9-82.9 CFM airflow and generate 9-36 dBA of noise. The fan can create 0.3-2.7 mmH2O of static pressure. The slide bearing should deliver at least 40,000 hours or 4.7 years of uninterrupted service. The electrical specifications of the fan can be found on its rotor sticker:

The fan is attached to the heatsink with two plastic tails with clips, which should be screwed on to the fan frame with included self-tapping screws:

Special rubber pads in the corners of the frame will absorb vibrations. There is an additional set of mounts for the second fan included with the cooler.

Cooler Master Hyper PWM 412 will be compatible with any contemporary platform. You can download the detailed installation manual from the official company web-site. The cooler installs very easily onto the LGA 2011 platform, which we traditionally use for processor cooling systems tests. First you insert threaded hexagon bushes into the socket retention holes:

After that you simply install the heatsink on top and secure it in place with an X-shaped backplate and a set of spring-screws:

That’s it: the cooler is secured on the mainboard and doesn’t interfere with the low-profile heat-spreaders on our memory modules:


Cooler Master Hyper PWM 412 doesn’t look bulky inside the system case. On the contrary it has more of a stylish and even aristocratic look:

Now let’s meet our next today’s testing participant.
