The German company Silent Power Electronics GmbH sells numerous PC components in Europe under the name LC-Power. In addition to cases, CPU coolers and fans, the portfolio also includes power supplies and other gaming equipment. The brand has also made a name for itself in the field of gaming monitors. In September 2024, the manufacturer expanded its cooler portfolio with the JetFlow series. With the LC-Power LC-CC-240-B – JetFlow, we have the smallest variant (almost) without ARGB lighting in our test today.
The LC-Power LC-CC-240-B – JetFlow has a 240 millimeter aluminium radiator, an rgb-illuminated pump block with copper plate and a TDP of up to 250 watts. It is also highly compatible with many old and all new sockets as well as unlit fans with a wide speed range. The LC-CC-240-B – JetFlow is priced at € 69.98 * and, as always, we start with the technical details.

Packaging & scope of delivery
The LC-Power LC-CC-240-B – JetFlow was packed in an inconspicuously printed cardboard box. On the outside, the color black dominates and some product images of the compact water cooling system or individual components are also visible on the box. LC-Power keeps all texts and technical information in a neutral white and also prints a table with all important information in three languages (German, English, French) on the back of the packaging.
When you open the box, you first come across a thin layer of foam and a mold made from recycled cardboard underneath. This is where LC-Power places all the components of the AiO water cooling system and wraps them in individual plastic films for additional protection. The scope of delivery includes the radiator/pump combination, two 120 mm fans, the necessary mounting material for all standard sockets, a tube of thermal paste, assembly instructions, a Y-PWM crossover for the two fans and a simple ARGB controller.
Design & workmanship
The radiator of the LC-CC-240-B – JetFlow measures 275 x 120 x 27 millimetres, is made of aluminum and is painted completely black. The manufacturer has dispensed with any lettering or eye-catching accents in the design. Only the side panels of the radiator have been provided with discreet indentations. LC-Power has also dispensed with any RGB lighting on or in the radiator. A valve for pressure equalization has also been placed on the side of the hose attachments of the heat exchanger.
The coolant is routed between the pump and radiator via two approximately 400 millimeter long hoses, which are covered with a close-meshed nylon fabric to improve the appearance. The manufacturer has pressed the hoses into metal sleeves on both the radiator and the pump, making the cooling system impossible to maintain or refill. However, the particularly flexible swivel joints on the pump block are a positive feature.
The pump block itself is also inconspicuously designed. The housing is made of black plastic and has been slightly refined with a silver manufacturer’s logo on the lid. The manufacturer has installed a pump with ceramic bearings in the housing, which is controlled via a 3-pin 12V connection. The CPU heat is dissipated via a large copper cooler base. Finally, the pump has a discreet ARGB strip on the right and top edge.
The two LC-Power CALMA fans supplied have a frame width of 120 millimeters and consist of a black frame and rotor blade with nine fan blades each. The fans can reach speeds of between 500 and 2000 revolutions per minute via the 4-pin PWM connection. To reduce vibrations, all eight corners have a layer of rubber.
The total weight of the LC-Power LC-CC-240-B – JetFlow is around 1.2 kilograms, which is generally average for compact water cooling systems. Equally average are the general dimensions of the LC-CC-240-B – JetFlow, which are neither particularly compact nor particularly expansive. As with the test of the larger 360 ARGB version, some of the fins of the radiator were slightly bent, but could be bent back into place with a toothpick.
LC-Power LC-CC-240-B – JetFlow Test: Assembly
A test system is used for the review, which is mounted on a benchtable. This allows us to rule out factors such as heat build-up in the case. The test system consists of the following components.
- AMD Ryzen 5 1400 @ 3.8 GHz at 1.175V*
- ASUS TUF Gaming B550M-Plus*
- Crucial Ballistix Sport LT gray 32 GB DDR4-3000*
- TeamGroup T-Create Classic PCIe 4.0 DL*
- Gigabyte AORUS GTX 1060 6G*
- LC-Power LC550 V2.31 Platinum Series 550W*
With an AMD system, the pump block is installed using the AMD retention module. All we had to do was remove the front plastic brackets and replace them with four spacers and washers. We then screwed the two necessary mounting brackets to the pump block.
If you are using an Intel system, LC-Power includes a modular metal backplate. This is placed at the rear of the mainboard and then also fitted with four spacers from the front. As the hole spacing is different for Intel, the manufacturer naturally also includes suitable mounting brackets for the CPU block.
The pump block is now screwed to the spacers independently of the socket. Four spring-loaded screws are used for this purpose. Installing the LC-CC-240-B – JetFlow was easy and should be quick for experienced PC hobbyists. For newcomers, the rather brief instructions could be a little clearer. On the other hand, the very high socket compatibility, which also allows installation on particularly old AMD and Intel sockets, is commendable.
Cooling performance and noise level
As already shown in the previous chapter, we use an AM4 system based on the Ryzen 5 1400 and the ASUS TUF Gaming B550M-Plus as test hardware. The Ryzen runs overclocked to 3.8 GHz at 1.175 V CPU voltage. To heat up the processor, we fully loaded it with Prime95 for 30 minutes per scenario (small FFTs). The temperature of the CPU was then read out with the CPUID hardware monitor. The room temperature was always around 20 °C during the measurements.

As can be seen in the table and diagram, the CPU of our test system reaches a maximum of 54.7 °C (at minimum speed), 48.6 °C (at 50% PWM fan and pump speed) and 45.5 °C (at 100% PWM fan and pump speed) under full load. These are very good values for a compact water cooling system with a 240 mm radiator.
The pump can be regulated between 1100 and 2600 revolutions per minute and is slightly audible from around 1500 to 1600 revolutions per minute. At maximum speed, a clear whirring and “gurgling” can also be heard here. However, we were able to almost completely eliminate the latter by increasing and decreasing the speed several times.
The fans can be adjusted between 600 and 2000 revolutions per minute. This spectrum therefore ranges from quiet to clearly audible. However, the volume is only due to the air noise, as we could not hear any background or running noises even with the unlit version of the CALMA fans.
LC-Power LC-CC-240-B – JetFlow test: Lighting options
Unlike the ARGB variants, the LC-Power LC-CC-240-B – JetFlow only offers one ARGB element. This is located in the identically designed pump block and was placed in the form of a thin strip on the right and upper edge of the CPU block. This variant is also controlled via a 3-pin 5V ARGB connector. The pump also has a splitter for the ARGB signal to make it easier to connect to a mainboard with few connections. If the mainboard used does not have a suitable connection, a simple ARGB controller is also included in the scope of delivery. Finally, a few impressions of the activated lighting.
Conclusion on the LC-Power LC-CC-240-B – JetFlow test
Now we come to the conclusion of the LC-Power LC-CC-240-B – JetFlow test. We were impressed by the overall simple but appealing appearance, which nevertheless does not have to do without the tasteful accent lighting of the CPU block. We also found the unlit versions of the CALMA fans to be positive, as they have a wide speed range, little to no background noise and made a high-quality impression overall. Finally, the smallest JetFlow version also has a high level of compatibility for many old and new AMD and Intel sockets as well as a generally solid mounting system.
The negative aspects of the LC-CC-360-B-ARGB – JetFlow can almost be adopted for the smallest and unlit version. The fans are clearly audible at higher speeds, but this is less of an issue due to the wide speed range and good cooling performance. However, this model also had to contend with slight damage to the radiator fins, very brief assembly instructions and a pump that whirred at higher speeds.
You can’t go far wrong with the purchase of the LC-Power LC-CC-240-B – JetFlow. However, apart from perhaps the high compatibility, there is no particular unique selling point with this compact water cooling system. Success therefore stands and falls with the estimated purchase price. When the test was completed, the cheapest price was still around €92 (as of 30.10.2024) and thus above the larger variants. The LC-Power LC-CC-240-B – JetFlow would of course not be recommended for this price. If it settles at around €70, this water cooling system would definitely be worth a closer look.
