Thermaltake Frio OCK CPU Cooler Review
By Rafael Otto Coelho on May 18, 2011
The Frio OCK is a new cooler from Thermaltake, with a tower heatsink, six heatpipes and two 130 mm fans. Let's test it.
Keep in mind that the Frio OCK is not an upgraded version of the Thermaltake Frio, which we reviewed some time ago. Actually, they have almost nothing in common, except for the fact that they both have tower heatsinks and two fans each.
The Frio OCK box is made of cardboard, with a picture of the cooler in the front, as you see in Figure 1.
Figure 2 shows what comes with the cooler: manual, thermal grease, and installation hardware. This hardware comes nicely packaged into a small box with a foam filling where every piece has its own place.
In Figure 3, you can see the Thermaltake Frio OCK. By the way, OCK stands for "Overclocking King."
This cooler is discussed in detail in the following pages.
Figure 4 shows the front of the cooler, where a 130 mm fan with semitransparent blades forces the air into the heatsink.
Figure 5 shows the side of the cooler. The heatsink is barely visible under the plastic cover.
Figure 6 illustrates the back side of the cooler, where the second fan extracts the air from the heatsink. Both fans have only one power connector, which has three pins. It also has a small potentiometer where you can adjust the rotation speed.
Figure 7 presents the top of the cooler. Here you can see the plastic cover, which has a transparent blue window at the center.
In Figure 8 you see the base of the Frio OCK. It is smooth but it doesn't have a mirror-like aspect.
Figure 9 reveals the cover off the heatsink. It can be removed just by pulling it from the sides. The fans are screwed to this cover.
By removing that cover, you can see the heatsink. It resembles the Prolimatech Megahalems heatsink, with two independent towers, as you can view in Figures 10 and 11. It's not a bad thing to mimic a champion design, is it?
Figure 12 shows the cooler base with clips attached to it and, in Figure 13, you see the backplate and the screws that go on the solder side of the motherboard.
After placing the backplate and the screws on the solder side of the motherboard, you need to install four plastic spacers and two metallic holders on the component side, as you can see in Figure 14.
Then, screw the heatsink to the holders.
Finally, slip the cover over the heatsink and connect the fans to the motherboard.
We tested the cooler with a Core i7-860 CPU (quad-core, 2.8 GHz), which is a socket LGA1156 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 3.3 GHz (150 MHz base clock and 22x multiplier), keeping the standard core voltage (Vcore), which was the maximum stable overclock we could make with the stock cooler. Keep in mind that we could have raised the CPU clock more, but to include the stock cooler in our comparison, we needed to use this moderate overclock.
We measured noise and temperature with the CPU idle and under full load. In order to get 100% CPU usage in all threads, we ran Prime 95 25.11 with the "In-place Large FFTs" option. (In this version, the software uses all available threads.)
We compared the tested cooler to the Intel stock cooler with a copper base (included with the CPU), as well as with other coolers. Note that in the past, we tested coolers with a socket LGA775 CPU, and we retested some "old" coolers with this new methodology. This means you can find different values in older reviews than the values you will read in the next page. Every cooler was tested with the thermal compound that accompanies it.
Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings. During the tests, the left panel of the case was open.
Operating System Configuration
We adopted a 2 °C error margin, meaning temperature differences below 2 °C are considered irrelevant.
The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at idle and at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the minimum speed on the idle test and at full speed on the full load test.

In the graph below, at full load you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.
The main specifications for the Thermaltake Frio OCK CPU cooler include:
* Researched at Newegg.com on the day we published this review.
The Thermaltake Frio OCK is a real winner, which has achieved a performance level that equals the best air coolers we have tested so far, including the Thermaltake Frio, which is a completely different cooler, despite its name.
Although it is very loud at full speed, it has a small potentiometer that controls the fans, allowing you to reduce the noise (at the cost of a little performance, of course). The cover that holds the fans is a great idea, being easy to remove and reinstall, which helps a lot if you have the habit of cleaning your system periodically.
Speaking of the fans, they are loud for a reason. They have a big airflow, which can be easily felt just by putting your hand behind the cooler.
The Thermaltake Frio OCK is a great cooler, beautiful, easy to install, costs less than most of its competitors, and shows a stunning performance, deserving the Hardware Secrets Golden Award.
