Design and Functionality
Although the name of this cooler is almost the same as that of the previous cooler modification, the new FrioOCK has very little in common with its predecessor. The only thing they share is probably only the type of the heatsink design – a tower. Everything else is totally different, starting with the exterior looks. FrioOCK sports StarCraft 2 design and is positioned as a stylish and uncompromising solution for the fans of this game. Semitransparent blue fan blades match the top plastic cover in color, and the bright-red inserts in the top part of the cooler make FrioOCK look uniquely laconic:
The cooler is pretty large in size: 158.4 x 136.8 x 143 mm, although it is not any bigger than any of the leaders in this department. Thermaltake FrioOCK cooler weighs 1093 g.
Almost the entire cooler heatsink is hidden beneath the fans and plastic covers of all sorts. Only the bottom parts of its sides and the actual bottom of the heatsink remain “naked”:
Note that all this plastic armor may be easily removed: just undo the clips on the sides of the heatsink and lift the whole thing up:
Beneath it, you will find a two-array heatsink made of 90 (45 per array) aluminum plates, each 0.4 mm thick. The plates sit on six copper nickel-plated heatpipes and are spaced out at 2.0 mm distance from one another:
Does this heatsink remind you of anything? You are right: it is a pretty close copy of Prolimatech Megahalems cooler, which we reviewed over two years ago. Even the number of plates is identical, not to mention their shape and the heatpipes layout. The only difference is probably the embossed “Tt” logotype on each plate, although this is an insignificant difference. Thermaltake obviously decided to take an easy route by copying a heatsink design that was a success for its time. However, while Prolimatech’s cooler had each of the heatsink plates made of two halves soldered to the heatpipes, Thermaltake’s FrioOCK has its heatsink plates made of a solid piece of aluminum and then pressed against the heatpipes. The effective surface area of the new Thermaltake cooler doesn’t exceed 7,000 sq. cm, which is a pretty modest number for contemporary super-coolers, and especially for a solution that intends to win the air-cooling leader’s crown.
Unfortunately, the heatpipes are laid out linearly inside the heatsink, so the heat won’t be distributed evenly over the heatsink array. This is a pretty strange solution, because Thermaltake currently offers a cooler with non-linear heatpipes layout – Thermaltake Jing (we are going to review it in one of our next articles). In other words, this is no new technology for the company. So, it is very unclear why they didn’t shift the heatpipes away from one another, which could allow them to achieve better heat distribution over the heatsink plates.
The heatpipes lie inside specially cut-out grooves and are soldered to them. The thinnest part of the cooler base beneath eh heatpipes is 2 mm.
The contact surface of the copper nickel-plated cooler base is finished quite nicely, although it is not ideally even: there is a small bump in the center, which immediately showed on our thermal compound imprint below:
Thermaltake FrioOCK is equipped with two nine-blade fans 130 mm in diameter and 25 mm thick:
The fans are not only installed for air intake/exhaust, but also rotate in different directions, which allows concentrating the air flow on the heatsink plates, according to Thermaltake. The fans are powered from one three-pin connector, with a small rotation speed regulator wired right next to it:
The fans are claimed to work in 1200-2100 RPM speed range, each fan creating 121 CFM airflow and generating 31-48 dBA of noise. The fluid dynamic bearings used in these fans should last no less than 50,000 hours. We were very surprised with the nearly gigantic power consumption of these fans , which is claimed to be 14.4 W! Our measurements showed that these two fans consume 12 W of power. It is a very impressive result, although it is not the ultimate maximum for the corresponding mainboard connector. The fans startup voltage turned out 3.7 V.
