The Tuniq Tower 120 utilized a three copper heatpipe design with a separate copper base, whereas the Extreme trumps the original with five copper heatpipes that are actually part of the base. The heatpipes on the Extreme seem to be made of a larger diameter copper heatpipe as well. The base of the Tuniq Tower 120 extreme also incorporates a secondary heatsink built into the cooler's base, presumably for faster transfer of heat away from the CPU. Taking a look at photos of the original Tower 120, it seems that the Extreme edition has either more aluminum fins, or maybe just larger ones, as the internal 120mm fan sticks out of the bottom of the older cooler much further than it's newer cousin. Probably the most striking visual difference we see in the two coolers is the black nickel plating that Tuniq has incorporated into the design of the Tower 120 Extreme.
Tuniq has gone with a direct-contact heatpipe design similar to some of the best performing coolers currently on the market. Will having five flat copper heatpipes in direct contact with the CPU's IHS improve cooling? We will put it to the test.
