Enermax ETS-T40 CPU White Cluster & Black Twister Review

A Closer Look – ETS-T40-BK
The black model comes fitted with T.B.Apollish 120mm fan which can run from 800-1800 RPM, it’s only mounted with clips, so it can easily be removed for cleaning, or you could even swap it out for any other 120mm fan of your choosing.
The cooler is beautifully finished in black, every fin, heat pipe and fixture with the exception of the fan clips looks sleek and stealthy and it really makes the Enermax logo on the top pop out thanks to the high contrast design.
The coolers fins have a patented feature which Enermax call Vortex Generator Flow or VGF, it’s the same principle that is used in aviation to make sure the airstream is as close to the wings as possible, the small notches near each heat pipe are there to do the same, only they’re designed to drive the air close to the heatpipes for better cooling.
There are more notches cut into the top centre of the fins, seen below the Enermax logo in the picture below. These are another patented design from Enermax that use Stack Effect Flow or SEF, these notches interrupt the air stream, allowing warm air to escape from the top of the cooler and creating a low air pressure to pull cool air in, as well as using a vacuum effect by pulling air through the sides of the cooler.
Enermax have skipped using a base plate altogether, instead favouring for direct contact between the CPU and the heat pipes. All four heat pipes have been cut and polished with just a solid block on the back of them for mounting to the motherboard and brackets.
With the fan removed the cooler measure just 70mm thick and with a maximum height of just 160mm it should be compatible with a huge range of chassis.
Many CPU coolers feature very fragile fins and while that is true of the ETS-T40, they are still a fair bit stronger and harder to bend than most other coolers we’ve tested.
The fan features a braided cable and standard 4-pin connection, although we would have liked to have seen the braiding cover all of the exposed cable, it just looks like a lazy job with part of it left uncovered. If you look closely you’ll also notice there are 12 LEDs on the fans interior.
