The features and specifications provided by Zero Infinity is quite sparse, and unlike many coolers we have covered before, there is little about the innovative features the Free Flow+ were designed with. Regardless, we can see that the cooler boasts some impressive characteristics, the key one being its dual tower design and 3 140mm fans operating at 1200RPM. Its five 8mm copper U-shaped heat pipes follows Phanteks’s suit, which as we know is currently the best CPU Cooler around, so that is a promising start for the Free Flow+. It is debatable whether Direct Touch technology aids in further cooler potential but we will investigate this in more depth later on.

In absolute terms, the Free Flow+ is a beast of a cooler and yet relative to other high end dual tower coolers, it is actually fairly compact. In terms of width, it is comparable to the Phanteks at 140mm, 4mm less than the K2. Height-wise, it stands at 165mm where other coolers tend to be 160mm or thereabouts. The depth on the other hand, isn’t as substantial as the other 3 high-end dual tower coolers. The heatsink itself is 111mm in depth, 25mm less than the Phanteks PH-TC14PE. This means that the Free Flow+ can accommodate an extra third fan without being deeper than the Phanteks using only two fans. So, despite losing some surface area, it makes up using a third fan.

The weight of the Free Flow+ is also significantly higher than the K2, our heaviest tested cooler, by 118g. Whereas the heatsink itself is only 7g heavier, the additional fan contributes to the added weight. The question is how a more compact heatsink can be heavier and whether the weight causes undue stress on the motherboard.
