Recently Enermax sent over one of its newest cooling products, the ETS-T40.

Here’s what they have to say about it:

• World leading thermal resistance performance of 0.09°C/W.
• VGF (Vortex generator flow) technology to greatly increase air convection.
• SEF (Stack Effect) design to enhance heat transfer.
• Unique air path creating high VEF (Vacuum Effect) to optimize the airflow.
• 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.Silence PWM fan to adjust the power efficiently and keep the silence.Dual fan installed option and solid springs attached.
• Anti-vibration rubbers prevent fan vibration and absorb noise.
• Universal bracket for Intel® 775/1155/1156/1366 and AMD® AM2/AM2+/AM3/AM3+/FM1.
• High thermal conductivity grease to ensure the best thermal conduction between CPU and the heat sink.

The ETS-T40 carries on the legacy of providing a great balance of performance and noise level during high and low speed operations. ETS-T40 is Enermax’ first cooler to be equipped with an all-in-one mounting solution that includes LGA 1156 and 1366. Direct Contact heat-pipe is now also utilized in this latest update.

Enermax ETS-T40-TB Packaging

Enermax ETS-T40-TB Packaging

The packaging utilizes quite a bit of whitespace in the design.

Enermax ETS-T40-TB Packaging

The Enermax ETS-T40-TB packaging is a sturdy cardboard that protected the cooler quite well.

The ETS-T40-TB

Once removed from the packaging our first thought was how much of how “airy” the ETS-T40-TB is, you can see through the widely spaced fins more than other heatsinks we have reviewed. The Enermax branding on the fan is even visible through the heatsink, as seen in the photo above. We will see how this design choice effects the performance later on in the review.

AMD/Intel Mounting hardware

The Enermax ETS-T40 ships with mounting hardware for both Intel and AMD components.

Enermax ETS-T40-TB Heatsink

The fins on the Enermax ETS-T40-TB are straight and reflective, aiding the “airy” look mentioned above. The fins on the ETS-T40 are the same thickness as the Cooler Master Hyper. Because of the wider spacing of the fins, we were concerned about damaging them at first, as the review went on it became apparent that they were more than strong enough to put up with any physical stress we put on them .

4 Pin Fan Connector – ETS-T40-TB

Front View ETS-T40-TB

The fan included with the Enermax ETS-T40 has a 4-pin power connector. Style wise, the fan has “Enermax” cut into the side, which is a feature that seems a little neglected without a backlit fan. Don’t worry though, Enermax has you covered: they also make a version of the ETS-T40 (the ETS-T40-TA and VD) which have backlit fans.
The fan included with the ETS-T40 features a double concave design as seen in the photos above. We will see how this design choice effects the performance of the heatsink later in the review when the heatsink is paired with our aftermarket fans.

Base Heatpipes – ETS-T40-TB

The 4 heatpipes on the ETS-T40-TB are staggered to allow the fins of the heatsink to saturate more evenly, allowing a lower overall temperature than if the pipes went through the same part of the fins.

Base Flatness – ETS-T40-TB

The ETS-T40-TB is relatively flat, though some space can be seen between the heatpipes and base. Extra care was taken to ensure the heatsink had just the right amount of TIM applied to make good contact.

Base Reflectiveness – ETS-T40-TB

The base of the ETS-T40-TB has a slight reflectivity to it, the photo shows Enermax took care to provide a smooth contact area on the ETS-T40-TB.
