Evercool Turbo2 is an inexpensive VGA cooler and thus must be analysed with its target audience in mind.
It achieved the same performance level of our GeForce 9600 GT stock cooler, which is a medium-consumption (and dissipation) video card. The good point is that it did it with a way lower noise level.
Regarding its looks, it is a matter of personal taste. It impresses by its size, but its huge plastic cover seems a little clumsy. In our opinion, the cooler would look a lot nicer if it was black.
An important drawback of Turbo2 is that it occupies two extra slots (i.e., two slots plus the slot used by the VGA). If you have some expansion cards (or are short of free slots) this can be a serious issue.
In summary, Evercool Turbo2 is a good option if you have a video card with a relatively low TDP and wish to replace the stock cooler with another one with better performance and/or lower noise, but it is not a viable option if you have a high-consuption video card.
