The Prolimatech Megahalems

The Megahalems joins the tower-format band wagon with a few twists. With dimensions of 130x74x158.7mm and a weight of 790g it’s a fair size and features two bold heatsink arrays separated by a 5mm gap.

A total of 6 copper heatpipes, in the traditional ‘U’ shape, emanate from the base and flow up through the fin stack to distribute the heat. Unfortunately, the heatsinks are all in the same line and so the heat is not exactly evenly distributed which doesn’t use the fin stack as effectively as it could.

The heatpipes are bent as little as possible though in order to keep resistance at a minimum for the heat flow inside the pipes.

The purpose of the dual heatsink arrays, according to the manufacturer, is to reduce resistance to the airflow produced by the fan. However, it would also seem to stop dead zones occurring in the heatsink.

Each array has a total of 45 aluminium fins which have relatively wide spacing; this should aid airflow through the fin layers as gaps are not too small which for fans with a low static pressure, can be a problem.

The heatpipes are soldered to the fins instead of piercing the plates (the latter is more widely seen) and this method does have one distinct advantage in that technological holes are not required as the fin stack is cut in half and then clipped around the heatpipes thus increasing the surface area that is in contact between the heatpipes and fins. Therefore, the cooling efficiency should be a little higher although it does look a little messier than piercing the plates.

The top aluminium fin has some imprinted patterns on it just adding a little style and the heatpipes have been nicely rounded off – this all contributes to giving a more professional appearance.

Now we move onto probably the most important part of a CPU cooler – the base – which contacts directly to the IHS on the CPU. The base is also usually a very good indicator to the quality of a product and in this instance, it’s not first class. Traces of solder and machine marks are noticeable but at least the surface is pretty flat and with the aid of some decent thermal paste should provide a good contact.

Prolimatech has chosen to not use HDT (Heatpipe Direct Touch) Technology and instead the heatpipes are again soldered to the base.
