Design and Functionality

One look at Thermaltake TMG IA1 is enough to remind us of ZEROtherm Nirvana NV120 Premium cooler. There is nothing surprising about it, actually, because the heatsink of the new Thermaltake solution as well as the design in general are very similar to those of ZEROtherm cooler:

Thermaltake TMG IA1 measures 140 x 97.4 x 160 mm and weighs 648g. These are pretty common size and weight for a contemporary tower-cooler.

The cooler heatsink sits on four copper heatpipes, each 6mm in diameter, that go through a copper base plate. The heatsink array consists of 51 aluminum plates:

 

The heatsink plates are spaced out at 2mm from one another. Each plate is 0.35mm thin. The sides of the heatsink are not covered with anything, which should ensure better cooling of the heatsink array, according to the manufacturer.

This I a pretty arguable statement, because if you cover the heatsink sides the cooler could turn out more efficient due to more economical use of the airflow created by the fan and concentrated in the center of the heatsink.

The heatpipes are slightly shifted inside the heatsink array:

 

Note that the side heatpipes are almost on the edge of the heatsink. Frankly speaking, I was a little puzzled by this implementation, because it means that part of the heatpipes will not work at its full potential. In other words, there is nowhere to transfer the heat to on that side.
