The processor cooler is delivered in a strictly designed box made of medium-thick corrugated cardboard.

The kit includes installation instructions in pictures and with explanatory notes in three languages: English, Chinese and Russian. Fasteners are primarily made of hardened steel (except for accessory posts and bushings) and have a durable galvanized or black paint finish.

The cooler is equipped with a remote radiator, to which heat from the processor is transferred through four heat pipes. The tubes are, of course, copper. At the base of the heat sink, the tubes are flattened and pressed into grooves. The heat sink is made of aluminum.

The tubes were ground flush with the base of the heat sink.

Although the kit did not provide a thermal interface, the manufacturer included a small syringe with thermal paste for the cooler. During testing, we used high-quality thermal paste from another manufacturer. Once the tests are complete, we will be able to demonstrate the distribution of thermal paste on the Intel Core i9-13900K processor.

And on the base of the heat sink:

The thermal paste was distributed in an even, thin layer over most of the surface of the processor cover, with excess material being squeezed out at the edges. A significant area of tight contact is observed.

The surface of the radiator, including its plates and heat pipes, with the exception of the working plane of the sole, has a black semi-matte paint coating. This coating to a certain extent helps to improve heat transfer by radiation. The radiator is a stack of aluminum plates tightly mounted on heat pipes, which are spaced apart to increase the efficiency of the cooling system. The top of the radiator is covered with a decorative plastic cover.

The standard size of the complete fan is 120 mm.

The fan operates as a blower and is secured with typical steel brackets. The second set of brackets will allow you to install a second fan on the other side of the radiator, this time, of course, for exhaust. The fan supports PWM control.

The cooler is shallow and the heatsink is slightly offset from the center of the processor. This allows easy access to all RAM slots from the top, such as on the ASRock Z790 PG Sonic motherboard.

The fastening structure is designed to eliminate over- or under-pressure (just tighten the nuts all the way, avoiding over-tensioning), and with two-point clamping, reduces the chance of uneven pressure or misalignment.

Determining the dependence of the cooler fan speed on the PWM duty cycle and/or supply voltage

An excellent result has been achieved: a smooth increase in fan rotation speed when changing the fill factor (FC) from 10% to 100% with a wide adjustment range. It is worth noting that at 0% short circuit the fans do not stop, which may require stopping such fans in a hybrid cooling system with passive mode at minimum load by reducing the supply voltage.

The range of adjustment using voltage in this case is approximately the same. The fan stops when the voltage drops to 2.4 V and starts from 3.6 V. It is quite acceptable to connect the fan to a source with a voltage of 5 V.

Determining the dependence of the temperature of the Intel Core i9-13900K processor when it is fully loaded on the rotation speed of the cooler fan(s)

In this test, all cores of the Intel Core i9-13900K processor ran at 3.7 GHz.

In fact, testing found that at an ambient temperature of 24°C, the processor begins to overheat at or below 20% duty cycle (corresponding to approximately 580 rpm). Some processor cores reach a critical temperature of 100°C, which is the maximum value for this processor. Under the conditions of this test, the maximum current consumption through additional connectors on the motherboard is 196 W.

Determining the noise level depending on the rotation speed of the cooler fan(s)

The noise characteristics of coolers vary depending on individual characteristics and other factors. Typically, noise levels at or above 40 dBA for a desktop system are considered quite high in our opinion. A range of 35 to 40 dBA can be considered acceptable and does not cause significant discomfort. Noise levels below 35 dBA do not stand out much compared to typical PC components such as case fans, power supply, graphics card or hard drives. A cooler that produces noise below 25 dBA can be considered silent. In tests, the background noise level was measured as 15.9 dBA (a measure indicating noise in the environment). Taking into account this value, this cooler can be classified as a device with a low noise level.

Plotting the dependence of real maximum power on noise level

It is known that the temperature of the ambient air entering the cooling system can reach 44°C, and at the same time it is necessary to control the temperature of the processor under maximum load so that it does not exceed 80°C. Given these conditions, let's assume that the actual maximum power (Pmax, representing the Maximum TDP) consumed by the processor depends on the noise level.

Taking a noise level of 25 dBA as a criterion for conditional noiselessness, the approximate maximum power of processors like the Intel Core i9-13900K corresponding to this noise level is about 141 W. Theoretically, ignoring the noise level, the power limit can be increased to approximately 170 W. It is important to clarify: this is calculated based on conditions of hard air flow to the radiator, heated to 44°C, and maintaining the maximum processor temperature at 80°C (up to 100°C is also acceptable). As the incoming air temperature decreases or the maximum permissible processor temperature increases, the specified power limits for silent operation and maximum power may increase.


The purpose of testing is to evaluate the ability of the cooling system (air cooler or LCS). Processors are used solely as a heating source to determine the thermal resistance of the cooler in various modes. The processor power is adjusted artificially, varying depending on the capabilities of the cooling system, which can be either less or more than the standard values. The main task is to prevent overheating of the processor throughout the entire cooling range (especially at a noise level of no more than 25 dBA) and to ensure a significant change in processor temperature.

Based on the ID-Cooling Frozn A410 Black air cooler, it is possible to create a conditionally silent system (with a noise level of 25 dBA or lower) equipped with an Intel Core i9-13900K processor. This is achievable if the thermal consumption of the processor at maximum load does not exceed 141 W, the air temperature inside the case remains below 44°C, and the maximum processor temperature is limited to 80°C. If the cooling air temperature decreases, the processor temperature threshold increases (up to 100°C), or noise requirements are less stringent, the cooling capacity can be increased. The advantages of this cooler include its neat design and the ability to be used together with high memory modules.
