Today we are testing the Arctic Cooling Freezer 7 Pro Rev. 2 CPU cooler, which has a tower heatsink, three 6 mm heatpipes, and a 92 mm fan. Check it out!
The Freezer 7 Pro Rev. 2 box is actually a transparent plastic blister, that shows the entire cooler, as you can see in Figure 1.
In Figure 2, you can see the cooler and the accessories that come with it: manual and installation hardware.
In Figure 3, you can see the Freezer 7 Pro Rev. 2.
In the next pages, you will see this cooler in detail.

In Figure 5, you see the side of the cooler. Note the three copper heatpipes.
In Figure 6, you can check the back of the cooler.
In Figure 7 you see the top of the cooler. Here we can see the simple fin design.

In Figure 8, you can see the base of the cooler, which comes with preapplied thermal grease.
In Figure 10, you can see the suspension mechanism that holds the fan, absorbing any vibration.
In Figure 11, you can see the frame for installing this cooler on Intel CPUs. There is no backplate. For AMD processors, the cooler is attached to the existing motherboard frame.
The first step of the installation is to attach the plastic frame to the motherboard, which is a very simple task. You can see it in Figure 12.
After that, the heatsink is set in place by screwing it to the frame. You must to remove the fan before doing this, in order to grant access to the screw.
After that, attach the fan to the heatsink and connect it to the motherboard.
[nextpage title=”How We Tested”]
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 (in this version, the software uses a
ll available threads) with the "In-place Large FFTs" option.
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.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off the case and video board cooler fans so they wouldn’t interfere with the results. This measurement is only for comparison purposes because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

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 Freezer 7 Pro Rev. 2 didn’t reach the same performance level of the top-notch CPU coolers we tested so far. The good news is that it has far better performance than the Intel stock cooler, and its fan is very quiet. The installation is very simple, too.
The real problem with this cooler is that it doesn’t have a good cost/benefit ratio. There are cheaper coolers with similar performance, and there are coolers that cost a little more but present far better performance.
Anyway, the Freezer 7 Pro Rev. 2 does its job: cools your CPU better than the stock cooler, while keeping your computer quieter.
