Design and Functionality

The only visible difference of the Hyper 212 EVO from the Hyper 212 Plus is the more advanced fan which goes under the name of Cooler Master Xtra Flo:



The cooler’s dimensions have not changed. It still measures 159 x 80 x 120 millimeters.

But its weight has been reduced by 57 grams to 569 grams. This is due to the lighter fan (104 rather than 166 grams) as well as minor changes in the design of the cooler’s base. The overall design hasn’t changed, though. The heatsink still consists of 57 aluminum plates with a thickness of 0.5 millimeters that are press-fitted onto four copper heat pipes, 6 millimeters in diameter. The fins are placed 2 millimeters apart from each other.


A 120mm fan is attached to one side of the heatsink.


The total size of the heatsink surface is about 6400 sq. centimeters. The heat pipes are placed in a checkerboard pattern in order to distribute the heat uniformly in the heatsink fins.

The manufacturer claims that this heatsink design is efficient both at low and high speeds of the fan. The product also features a universal fastening mechanism and an original fan. You can attach a second fan to it.

For us, the key feature of the Hyper 212 EVO is its direct-touch technology:

There are no aluminum inserts in between the copper heat pipes, which ensures better removal of heat from the processor. Cooler Master refers to this as Continuous Direct Contact.

As you can see, the new technology is supposed to ensure 5% lower temperature and 6% larger contact zone. The reduction of the dead zones in between the heat pipes should indeed lead to higher efficiency. The cooler's base is flat but not finished perfectly.

The Cooler Master Hyper 212 EVO comes with a single 120x120x25mm Xtra Flo fan.

We saw a fan with the same impeller in our recent test of Cooler Master’s Hyper 612S. Its rotation speed is PWM-regulated from 600 to 1600 RPM at a noise level of 9 to 31 dBA, air flow of 24.9 to 66.3 CFM and static pressure of 0.3 to 1.7 millimeters of water. Its sleeve bearing is expected to serve for 40,000 hours (or 4.5 years) continuously. The peak power consumption of the fan is 2.28 watts. According to our measurements, it consumed 3.2 watts and could start up at a voltage of 3.8 volts. The fan is secured on the heatsink with two plastic details that are locked on the side slits in the heatsinks. There is another pair of such details in the box so that you could attach a second fan if you want to.
