Hardware Secrets Silver Award

Today we are testing the Freezer i30 CPU cooler from Arctic, which is targeted to Intel CPUs. It has a tower heatsink, one 120 mm fan, and four direct-touch 8 mm heatpipes. Check it out!

Arctic offers two coolers that are actually almost the same product: the Freezer i30 (that we are reviewing here) and the Freezer A30, which is the same cooler, but aimed at AMD CPUs.

The Freezer i30 comes in a compact white cardboard box, as shown in Figure 1.

Figure 8 illustrates the base of the cooler. The heatpipes touch the CPU directly, and there is no gap between them. The surface has no mirrored finishing.

Figure 11 shows the backplate for installing the Freezer i30 on socket LGA1155/1156 CPUs. Socket LGA2011 systems don’t require a backplate.

In order to install the Freezer i30, you need to put the backplate on the solder side of the motherboard, and then install the holders shown in Figure 12, using four plastic spacers.

After that, install the heatsink, securing it with two screws.

The last step is to install the fan, as you can see in Figure 14.

How We Tested

We tested the cooler with a Core i5-2500K CPU (quad-core, 3.3 GHz), which is a socket LGA1155 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 4.0 GHz (100 MHz base clock and x40 multiplier), with 1.3 V core voltage (Vcore). This CPU was able to reach 4.8 GHz with its default core voltage, but at this setting, the processor enters thermal throttling when using mainstream coolers, reducing the clock and thus the thermal dissipation. This could interfere with the temperature readings, so we chose to maintain a moderate overclocking.

We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, 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 other coolers we already tested, and to the stock cooler that comes with the Core i5-2500K CPU. Note that the results cannot be compared to measures taken on a different hardware configuration, so 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 on the next page. Every cooler was tested with the thermal compound that comes with 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 panels of the computer case were closed. The front and rear case fans were spinning at minimum speed in order to simulate the “normal” cooler use on a well-ventilated case. We assume that is the common setup used by a cooling enthusiast or overclocker.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top opening of the case. 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.

Error Margin

We adopted a 2°C error margin, meaning temperature differences below 2°C are considered irrelevant.

Our Tests

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 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 full speed.

In the graph below, 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.

Main Specifications

The main specifications for the Arctic Freezer i30 CPU cooler include:

* Researched at on the day we published this review.


The Arctic Freezer i30 is a good CPU cooler with reasonable cooling performance and an almost inaudible fan. It will probably perform better if you change the stock fan for a more powerful one, which makes it a very versatile cooler. However, the new fan might not be as quiet as the fan that comes with the product.

This versatility, the good performance, low noise level, reasonable price tag, and great overall quality make the Arctic Freezer i30 a great choice, so we are giving it the Hardware Secrets Silver Award.
