The Frio OCK is only 50g heavier than the Frio, weighing in at 1,093g. Thankfully there is a backplate because this would be a substantial weight to place on a reference bracket.
The cooler measures 158.4mm x 143 mm x 136.8 mm (HxLxW). The Thermaltake logo is clearly seen from the top of the plastic shroud and each of the 130mm fans comprises 9 clear blades. Each of the fans can spin up to 2,100 rpm generating an airflow of 121 cfm, with noise levels up to 48 dBa. The shroud can actually take 120mm fans as the mounting holes are identical.
The plastic shroud is attached by a clip which is built into the heatsink itself. This is smooth in operation and means you can easily remove it, even when inside a case. We like this idea as it makes access a lot easier.
Each of the heatsink sections has 45 aluminum fins, which are 0.4mm in diameter. The fins have a slight concave implementation to help force the air across the length. From the top, the heatsink looks very like the Prolimatech Megahalems but there are some slight design differences. The six 6mm heatpipes are all copper, and nickel plated and the surface of the CPU contact head is very well finished with no marks on our sample.
Both of the fans are controlled from a small VR control knob which can be adjusted through a wide range of settings. We like the fact that Thermaltake have connected both fans to the same adjustment controller.
