The TRUE Spirit 120M is made of a nickel-plated copper base, four 6 mm thick copper heatpipes, and 45 aluminum fins. According to the specifications, it measures 132 x 57 x 145 mm or 5.2 x 2.2 x 5.7 inches (L x W x H) and weighs 470 grams or just over a pound, including the fan. However, our measurements peg its height at 146 mm and its weight at 550 grams, 460 grams sans fan.

Following in the footsteps of previous Ultra series models, the 120M has a slanted fin design. The fins are 0.43 mm thick and spaced 1.78 mm apart, on average. The fin density is greater than most tower coolers.

Like the HR-02 Macho, the heatpipes are bent near the base, shifting the bulk of the heatsink off to one side. Adding a fan on the opposite side balances the weight and makes the width more centered in relation to the CPU and socket. The fins of course adhere to the Ultra series' bent "winglet" design.

Thermalright didn't make full use of the allotted height — the heatpipe ends stick out 1.5~1.6 cm at the top.

The base is slightly convex at the center and has been polished to a mirror shine.

The TRUE Spirit 120M ships with the latest variant of Thermalright's universal mounting kit used with recent models like the Archon SB-E and HR-02 Macho.

The mounting system puts pressure directly over the base of the heatsink to maximize contact with the CPU heatspreader. It also makes the cooler a snap to remove for CPU upgrades, etc.

With the heatsink being off-center the fan doesn't extend past the boundary of the mounting frame. There is between 38 and 54 mm of clearance underneath the bottom fin.
