ID-COOLING FROSTFLOW 240L Review and test liquid cooling system

ID-COOLING FROSTFLOW 240L Review and test liquid cooling system


About fifteen years ago, a relatively young company ID-COOLING unveiled its version of the factory liquid cooling system – ID-COOLING FROSTFLOW 240L.

Add that to date, the assortment of company systems with 240-mm radiator series FROSTFLOW extended to three versions, though they differ from each other only fans the color (red, blue and white), and there was liquid cooling system, designed for graphics cards – FROSTFLOW 240G.

ID-COOLING FROSTFLOW 240L: Packaging equipment

System ID-COOLING FROSTFLOW 240L comes carton medium in size, on the front side of which is incorporated cooler photos and lists its main advantages.

The reverse side of the box reserved for the description of the advantages of the system compared to other factory LSS.

At one end of the box shows the two tables: a specification and a list of supported processor sockets.

Well, and the sides of the four reserved for circuit components and a photo with the dimensions.

Inside the main box placed an additional box of porous cardboard. In its compartments and are components of the LSS, additionally sealed in plastic bags. In other words, the package is reliable enough to withstand all the vicissitudes of shipment and delivery.

The scope of delivery includes a universal system reinforcement plate with an insulating gasket, two pairs of steel rails, Y-cable for the fans, set screws and washers to secure the water block, a set of screws to fasten the two types of fans and heat sink, as well as installation instructions.

In addition, there is a thermal grease ID-TG11 supplied systems with thermal conductivity> 5.15 W / (m * K) mass of 1 gram. This thermal interface has been tested by me in a separate article and showed quite good results.

Produced system in China, and her three-year warranty is provided. For more than a year of market presence recommended price ID-COOLING FROSTFLOW 240L declined from almost one hundred US dollars to 89 US dollars, making it more competitive in comparison with their classmates. Let’s see what it is.


Design ID-COOLING FROSTFLOW 240L is not original. She, like most factory LSS is a maintenance-free, already tucked and ready-to-operate system consisting of a heat sink mounted with a two fans, and pumps with water-block, connected to each other hoses.

At the heart of this model is one of the Asetek platforms with aluminum heat sink dimensions 274 × 120 × 27 mm.

The thickness of the heat sink fins is only 15 mm, that is, on the whole area of the radiator at low, but it will be easier to blow than radiators increased thickness.

At fourteen flat channels moves refrigerant pumped pump, and between them glued aluminum Corrugated. The density of the radiator is 19 FPI (fins per inch).

Threaded holes for mounting 120 mm fans on both sides there is a radiator, i.e., a total of four 120 mm fan can be installed on it.

The radiator is connected to the pump by two hoses external diameter of 10 mm and 305 mm in length.

Hoses are relatively rigid, that, on the one hand, to minimize the probability of inflection during installation or operation, but on the other hand, complicates the installation of the system in the system block.

On one of the two ends of the radiator fittings pressed in hoses.

Their removal or replacement of the regular method is not available, unfortunately.

Unlike Asetek systems, ID-COOLING FROSTFLOW 240L is equipped with an improved pump sizes Ø65 × 31 mm. The design of the pump is as follows.

The characteristics indicate that the performance of the pump is 96 liters per hour, whereas in Asetek-performance pumps systems (according to some independent estimates) does not exceed 50 liters per hour. Specified in the characteristics and the height of the liquid lifting pump of 1.2 meters, as well as the speed of the rotor pump – 2500 (± 10%) / min. However, the latter, according to the results of our measurements, it was about 2120 rev / min. The service life of ceramic bearing pump must be at least 50 000 hours, or more than five and a half years of continuous operation. The energy consumption level according to the specifications can be up to 3 watts, according to our measurements – 3.7 watts. The noise level is not reported to exceed 25 dBA.

Rotary pump fittings facilitate the installation of the water block on the CPU and prevent the possible excesses of hoses.

The top cover pump equipped with a backlight.

At the base of this unit is installed copper water block designated eight screws.

Its design consists of a thin copper fins height of not more than 5 mm from the intercostal spacing of 0.2 mm.

The quality of the contact surface of the water block treatment, carefully closed from scratches and damage the thick film, it is at a fairly high level, even without polishing.

Fingerprint CPU heat spreader constructive LGA2011 based on the water block was quite satisfactory – nip in the central part had a uniform, only one corner of the CPU does not fit tightly to the water block, which, given the location of the crystal is not critical.

Another difference between ID-COOLING FROSTFLOW 240L are firm fans model ID-COOLING SF-12025 measuring 120 × 25 mm with a black odinnadtsatilopastnoy impeller diameter of 113 mm and a stator diameter of 41 mm. Due to the red ring and the same inserts in the corners and a glossy notches on the blades, these fans look very attractive.

This fan model has been developed with an eye on high static pressure, and to achieve this goal has blades with a large angle of attack, expanding the ends.

Fans are equipped with PWM control and must rotate in a speed range from 800 to 2100 (± 10%) / min. The maximum air flow for each fan is stated at around 84,5 CFM, static pressure – 3.2 mm H2O, and the noise level should not exceed 38.2 dBA.

At the heart of the fans are hydrodynamic bearings, the life of which, unfortunately, is not given in the specifications. However, a three-year warranty provided on the system, allows us to assume that these fans can last for a long time.

As for the electrical specifications, here SF-12025 nothing special stand: 12 V, current of 0.38 A and a power consumption of 4.56 watts. At the same time according to the results of our measurements, each fan consumes less than 4.2 W, which is slightly lower than stated in the power characteristics, and starting voltage was equal to 4.1 V.

To fix the fan on the heatsink can be used two types of screws supplied, as well as used here vibrorazvyazki soft silicone inserts on the corners of the frame.

Both fans can be connected to one chetyrёhkontaktnomu connector on the motherboard or computer fan control, which has included the Y-piece 70 mm in length and the total length of the cables with them will be 370 mm.

ID-COOLING FROSTFLOW 240L: Compatibility and Installation

Water Unit ID-COOLING FROSTFLOW 240L is compatible with Intel-based linings an LGA775 / 115 (x) / 2011/2011-v3 and AMD processors with connectors Socket AM2 (+) / AM3 (+) / FM1 (2+). In other words, it supported by any modern processor. With regard to the placement of the system within the system unit, then it will take two adjacent seats of a 120 mm fans that modern buildings is not a problem (including the middle class).

Despite the fact that the installation of the system is simple and intuitive, the kit includes a detailed step by step instructions, an electronic version which can be downloaded from the site. First to the bottom of the water block FROSTFLOW 240L screwed two steel rails with holes for fastening. For Intel processors, they are as follows.

Further, the holes of the base plate LGA2011 processor socket on the motherboard screwed sleeve with thread.

It is to these sleeves nuts scored and drawn the water block. It is also important to make it as evenly as possible and slowly tightening the nuts on the diagonal, rather than from one side to the pressurizing force is spread over the entire area of the CPU heat spreader. Of course, do not forget about the thermal interface, which must be applied to the processor the lowest possible layer.

The water block on the CPU is more convenient to fix after the fact, as will be designated a radiator with a fan on the system case. In our case, we have placed the ID-COOLING FROSTFLOW 240L at the top of the chassis Thermaltake Core X71, and the fans are orientated to the direction of air flow on the release of the body.

Then just have to connect the fans to the Y-cable and powered by its corresponding chetyrёhkontaktnogo connector on the motherboard. The pump is connected to the same connector, with connector to better increased power, which increasingly began to appear on the new motherboards. After turning the system on the pump light appears in the form of traveling in a circle counterclockwise red LEDs. We add that the entire process of installing ID-COOLING FROSTFLOW 240L takes less than 10 minutes.


To evaluate the efficiency of the cooling system, eight cores at the reference frequency of 100 MHz at a fixed value in the multiplier 38 and fixed on the third level stabilization function Load-Line Calibration was overclocked to 3.8 GHz with an increase in voltage in the BIOS of the motherboard to 1.12185 in.

Voltage memory modules was fixed at 1.35, and its frequency was 3.0 GHz timings 16-16-16-28 CR2. In addition, the BIOS were made several minor changes relating to the acceleration or the processor memory.

CPU load created by two successive cycles LinX AVX2 with the above settings. On the CPU temperature stabilization between cycles allotted for 8-10 minutes. For the final result, which you will see in the diagram, received the maximum temperature of the hottest of the eight CPU cores at peak load and at idle. In addition, in a separate table will be given the temperature of the processor cores and their average values. The room temperature is checked next to the system with an electronic thermometer with a measurement accuracy 0,1 ° C and with hourly monitoring temperature changes in the room for the last 6 hours. During this test the ambient temperature ranged 21,5-22,2 ° C.

The noise level of the cooling system was conducted electronically sound level meter OKTAVA-110A in the period from zero to three o’clock in the morning in a fully closed room of about 20 m 2 with double-glazed windows. The noise level is measured in the system case, when the source of the noise in the room was just the cooler / LSS and the fan (s). Sound Level Meter fixed on the tripod is always located strictly at one point at a distance of 150 mm from the flat fan rotor. Cooling systems were placed at the corner of the table on the polyurethane substrate. The lower limit of the sound level meter measurements is 22.0 dBA, and subjectively comfortable (not to be confused with low!) The level of noise coolers at measurements at this distance is about the level of 36 dBA. For conditionally quiet noise levels we take the value of 33 dBA.

The first competitor to current ID-COOLING FROSTFLOW 240L is liquid cooling system of the same class Cooler Master MasterLiquid Pro 240, which, in fairness, it is more expensive – 119.9 US dollars.

The second contender is our benchmark super-cooler Phanteks PH-TC14PE, tested in operation with two 140-mm fans Corsair AF140 Quiet Edition.

Add that the speed control system of fan cooling was performed with a special controller to within ± 10 rev / min in the range of 800 rev / min to a maximum of 200 or step 400 rev / min.

Unfortunately, ID-COOLING FROSTFLOW 240L conceded not only more expensive Cooler Master MasterLiquid Pro 240, but also super-cooler Phanteks PH-TC14PE. Even at a maximum speed of its two fans FROSTFLOW 240L two degrees Celsius is less efficient than the air cooler at 1090 rev / min, and even at 1600 rev / min is inferior degree PH-TC14PE with a pair of 140 mm fans 800 rev / min.However, when compared with the system FROSTFLOW 240L MasterLiquid Pro 240 with the fan speed of 1000 rev / min, the difference in peak temperatures no no, and at 800 rev / min system ID-COOLING already outperforms Cooler Cooler Master three degrees Celsius. Nevertheless, the overall efficiency of the heroine of today’s test is not impressive. Let’s see what will happen next.

And then we sped up the processor to one more step – up to 3.9 GHz with a voltage of 1.16875 V.

In general, the balance of power has not changed, although the temperature increase is obvious. At the maximum speed of its regular fans ID-COOLING FROSTFLOW 240L behind the Cooler Master MasterLiquid Pro 240 by 7 degrees Celsius in the peak load on average (1200-1600 rev / min) – 3-4 degrees Celsius, and in silent mode at 800 rev / min only two degrees Celsius. Note the relatively high dependence of the efficiency of FROSTFLOW 240L radiator on the fan speed. The total increase in temperature during speed changes from 800 to 2050 rev / min it was 11 degrees Celsius, while the same system form factor Cooler Master in the same speed range loses over 13 degrees Celsius, but the initial high efficiency does not allow her to lose to a competitor. And yet, in comparison with the super-cooler of the two liquid cooling systems do not look convincing.

The final stage of testing the cooling efficiency was an attempt to overclock the processor cooled by ID-COOLING FROSTFLOW 240L, up to 4.0 GHz with a voltage of 1.2095 V.

The cooling system has coped with this quite a daunting task, but only with maximum speeds of two regular 120-mm fans.

Reduced speed at least to the level of 1 600 r / min is no longer possible to ensure the stability of the LSS to overclock the processor as the temperature reaches a critical value.

Noise level

Noise level participants of our today’s test was measured over the entire range of work for their fans set out in the relevant section of the article and the method presented in the graph.

If pump ID-COOLING FROSTFLOW 240L for our measurement methodology noise just 30.5 dBA, which can be called a silent mode of operation, the fans calm down only at lower speeds up to 780 rev / min, and are comfortable to 870 rev / min. Moreover, starting with 740 rev / min Fan ID-COOLING inferior to the noise level of more expensive Cooler Master fans of the same size, and the higher the speed, the greater the difference in dB. Ultimately, fans FROSTFLOW 240L at a speed of about 2000 rev / min noise as well as fans Cooler Master at about 2560 rev / min. So here, unfortunately, the account is not in favor of a system of ID-COOLING. At the same time, we note the absence of cod bearing fans and electrical noise in the whole speed range of operation.


Liquid Cooling System ID-COOLING FROSTFLOW 240L is quite a typical representative of this class of LSS with its own advantages and disadvantages. The first group we otnesёm high cooling efficiency at maximum fan speed, silent pump with enhanced performance and lighting, ease of installation and no maintenance, completely universal water-block, three-year warranty and a very reasonable price ($ 89), efficient and disposable thermal paste, and very attractive design. Among the shortcomings can not be called aluminum radiator and, as a consequence, the high dependence of the temperature of the fan speed, which does not allow FROSTFLOW 240L maintain a decent cooling performance in a quiet mode. In addition, the system ID-COOLING several lagged behind competitors’ products, which implement collapsible fittings, possibility of refueling or replacement refrigerant, and some of them even put copper radiators. Let’s hope that the company ID-COOLING will also move in this direction and following its liquid cooling system, we have to really impress.
