GELID Solutions is an interesting PC accessory manufacturer dealing in fans, coolers, and cases. Started by former employees of Arctic Cooling, the Hong Kong based company has kept their product catalog surprisingly sparse since their inception in 2008. The positive implication is that prefer to refine their focus on a small set of well-designed merchandise rather than spamming the market with volume regardless of quality like some companies. Their most impressive offering thus far, in our opinion at least, is the Icy Vision a well-designed dual fan GPU cooler that delivers excellent performance at a low noise level. Today we look at a pair of their latest CPU coolers, the GX-7 Rev.2 and Tranquillo Rev.2.

The Tranquillo Rev.2 and GX-7 Rev.2 box.

It's not clear exactly what the differences are between these Rev.2 models and their originals. There is no mention of the Rev.2 GX-7 on GELID's website and the specifications of the original Tranquillo are the same as its successor. In any event, the Tranquillo Rev.2 represents GELID's current mid-range heatsink offering while the GX-7 Rev.2 is their high-end flagship cooler, if you couldn't tell by the far more decorative artwork on the GX-7 box . As the two packages are the same size one could infer that the heatsinks themselves have similar physical dimensions. The main differentiators seems to be the GX-7's three extra heatpipes (7 vs. 4) and its branded Wing 12 PL fan.

Package contents.

The package contents of the two coolers are, as you probably guessed, identical. The heatsink and included 120 mm fan is secured in a thin plastic clamshell container with a small white accessory box (not pictured) holding the installation instructions and mounting hardware. The installation gear is exactly the same as well except the GX-7's kit has an extra set of fan clips for dual fan operation.

Similarities are also found in the build of the two heatsinks. They both have copper bases fused to tightly packed heatpipes with generous amounts of solder and friction-fit aluminum fins that are bent at the sides for stability and presumably to focus the airflow in the desired direction. The GX-7 is slightly larger with few extra fins and seven nickel-plated copper heatpipes to the Tranquillo's bare set of four.
