Stack Effect Flow (SEF):


The Stack Effect Flow is a natural, physical phenomenon: warm air is rising up because of its lower density and leaves a low pressure behind that pull cool air. Two openings in the middle of the heatsink can make use of this effect. They interrupt the air stream so that the warm air gains space to escape. The heat dissipation can be accelerated.


Vortex Generator Flow (VGF):


Vortex generators are applied in aviation industry. They make sure that the air stream is lead as close as possible along the airplane’s wings. During the CPU cooler development, the Enermax engineers recognised the potential of this technology to optimise the air stream inside the heatsink. Small spoilers on the fins, the so called Vortex Generators, conduct the air close along the heat pipes. Much more fresh air can be transferred to the back of the heat pipes.


Vacuum Effect Flow (VEF):


Also the third innovation makes use of a physical effect. The best example to explain this effect is a moving car; it pushes air aside as it goes down the road and leaves a low pressure. Air from sides will be sucked in to compensate the difference in pressure. According to that, the CPU cooler sides are not fully closed, so that cool air can be sucked into the heatsink.


Twister Bearing Technology:


All fans that come along with the Enermax CPU coolers are based on the patented Twister Bearing Technology. The functional principle of this bearing is quite simple; after switching on the fan, a metal ball inside the bearing becomes magnetised and keeps the blades on the fan shaft, it is the only point of contact, so that the fan runs smooth and almost frictionless. The bearing sleeve is made from a self-lubricating nano material that protects against abrasion. That way, Enermax guarantees a MTBF of minimum 100,000 hours, and a persistently silent fan run.


For more information regarding Enermax’s innovation and testing methodologies, have a look at their documentation. Science lesson aside, let’s take a closer look at their ETS-T40 cooler.
