Looking Closer at the Enermax ETS-T40-TA

Enermax ETS-T40-TA CPU Cooler

The Enermax ETS-T40-TA comes with the fan preinstalled. The cooler overall stands 160mm or 6.2 inches tall so users with smaller cases with side panel fans will want to do some measuring to check clearances.

The Enermax ETS-T40 has four ‘U’ shaped heatpipes and 52 cooling fins. The ETS-T40-TA we have has nickel plated heatpipes. The ETS-T40-VD and ETS-T40-TB come with an anti-oxidization coating on the heatpipes.

Looking from the top the ETS-T40 has a symmetrical fin profile that will allow for dual 120mm fans for a push/pull arrangement. The way Enermax designed the ETS-T40 the cooler is directional, so there is a certain way the fans have to be mounted to the cooler.

Enermax ETS-T40-TA CPU Cooler fins

This is due to the raised portions of the cooling fins. These raised areas to the outer edge create what Enermax is calling “Vortex Generator Flow”. As the air moves through the fins it hits the raised portions and is then redirected to areas behind the heatpipes that normally do not see a lot of air flow. The bumps in the center create what Enermax is calling “Stack Effect Flow;” the bumps at the exhaust area enhance the air speed, pressure, and its direction to enforce the heat transfer.

Enermax ETS-T40-TA CPU Cooler side

The closed section of the side and the corners of the fins themselves create what Enermax is calling “Vacuum Effect Flow.” As air is pushed into the heatsink by the fan, the fins create an air channel which results in additional air being sucked in.

The base top is clear except for two small holes. These holes are for the mounting system. The mounting system cross bar has two posts that fit into the holes, centering and preventing the cooler from turning.

The base of the ETS-T40 is an H.D.T. or Heatpipe Direct Touch base. Each of the 3 EST-T40 models all have the same base configuration, but the ETS-T40-TA model we are looking at is nickel plated.

Enermax ETS-T40-TA CPU Cooler fan

The fan that is included with the ETS-T40-TA is a blue LED 120mm Twister-bearing PWM controlled fan. The fan operates at 800 to 1800 RPM, pushing 33.26 to 75.98 CFM at 16 to 26 dBA. So the included fan will push a decent amount of air, and on the lower end will not be noticeable. On the high side, depending on the case, it could be noticeable at 26dBA, which is still an acceptable noise level. You’re not going to have to crank up the speakers to drown out the fan. As you may have noticed, the leading edge of the fan blades has a strip of chrome. This adds a little bling to the fan, and as you will see in the installation section, gives a nice effect with the LEDs.

Now most LED fans have a couple of large LEDs in the corner of the fan body. The fan for the ETS-T40-TA has a whole slew of them around the inner rim of the fan body. With this many LEDs, this fan is going to be bright.
