What Enermax has to say on their ETS-T40:

The Twister fans from Enermax have already built up an excellent reputation in the PC cooling segment. “Cooling by Enermax” stands for first-class quality, highest performance and silent operation. Fan series like T.B.Silence belong to the bestsellers in European case fan market. Now, the manufacturer is going to extend its successful cooling range: Prototypes of the first Enermax CPU coolers have been already shown on this year’s CeBIT. In the mid of August, the first side-flow models will be introduced into the market, followed by two top-flow models in September.

With the side-flow series ETS-T40 Enermax presents a CPU cooler with a revolutionary cooling performance: The thermal resistance of the CPU cooler reaches 0.09°C/W, a value clearly below the models that are currently available on the market. Even CPU coolers with more and thicker heat pipes do not achieve the performance of the ETS-T40.


•World leading thermal resistance performance of 0.09C/W.
-Patented VGF (Vortex generator Flow) Technology to greatly increase air convection.
-Patented SEF (Stack Effect Flow) design to enhance heat transfer.
-Unique air path creating VEF (Vacuum Effect) to optimise the airflow.
-Patented HDT (Heat Pipe Direct Touch) Technology to ensure rapid thermal conduction and eliminate CPU hotspot.
•Side flow type with four 6mm high performance heat pipes.
•Unique T.B.Apollish PWM fan to adjust the power efficiency.
•Eye-catching and bright colours thanks to patented circular LED light.
•Smooth running and persistent silent 12cm fan with patented Twister Bearing Technology
•Nickel-plated heatsink to reduce oxidation effect and maintain the top performance.
•Dual fan installation option and solid spring attached.
•Anti-vibration rubbers prevent fan vibration and absorb noise.
•Universal bracket for Intel LGA775/1155/1156/1366 and AMD AM2/AM2+/AM3.
•High thermal conductivity Dow Corning (TC-5121) grease to ensure the best thermal conduction between CPU and the heatsink.

The Enermax ETS-T40 boasts an extensive list of features, technologies and innovations. One could argue that the purpose is purely for marketing but as always, our thorough sets of tests will put their claims to the challenge. To start off, we see Enermax highlighting their cooler’s thermal efficiency which at 0.09C/W is very impressive. But as always, these figures are proportional to delta temperatures which can have many ambient factors contributing to the value. As such, the thermal efficiency figure alone isn’t noteworthy without other coolers being tested under the same conditions.

In terms of construction and dimensions, the Enermax cooler is very similar to the Cooler Master 212+ sharing the same tower design and Copper & Aluminium construction. Both also feature Heat Direct Touch technology and four 6mm heat pipes. The ETS-T40 is approximately 1.5mm taller, 19mm longer and 13mm deeper.

The bundled fan also boasts some very impressive characteristics such as PWM functionality, a unique bright LED illumination, up to 1800RPM operational speed, with excellent airflow and static pressure. They are also rated to be reasonably quiet at full speed. Given the normal retail price of the T.B.Apollish fan, it makes an excellent addition to the cooler, although driving up the costs slightly.
