Design

Let’s take a look at the Thermaltake V1:

That’s original indeed. I haven’t seen any cooler designed like that before.

The cooler’s heatsink consists of two fan-like parts (this must be the reason why the cooler is called V1) each of which hangs on a couple of 6mm heat pipes:

So, this cooler employs four pipes rather than two as in the Zalman CNPS8700 LED. There are a total of 102 ribs here (2 x 51), each 0.2mm thick. The ribs have contact with the pipes by means of thermal glue rather than solder as would be ideal. As a result, you can even move some ribs a little along the pipes. They don’t hang loosely by themselves, though.

Nestled between the two heatsink halves is an impeller from a 120mm fan. It is 110mm in diameter.

The airflow from the fan goes to both heatsink halves at once: an incoming flow for one and an outgoing flow for the other. The heatsink is braced with a couple of plates on each side for more rigidity. The ends of the heat pipes go into these plates.

The fan impeller is fastened on a metal pole in one position.

I mean you can’t turn the fan around to change the direction of its airflow, yet I don’t think anyone would want to do so. By the way, this TT-1225A (Everflow) fan is equipped with three blue LEDs.
