Let’s dive deeper into the cooler design.


Upon close inspection, the 240mm radiator is all-black Aluminum, measuring 38mm thick and 277×120 mm in size. It’s notably 13mm thicker than most 240mm AIO radiators, which could pose space challenges in smaller cases. The increased thickness enhances fin density to 14 fins per inch, offering improved airflow and lower fan RPMs. Consider the dimensions when planning your PC setup.

As I mentioned earlier, ARCTIC has pre-installed the fans on the radiator to simplify installation and keep cable management tidy. The fans are set up for a push flow configuration, promoting airflow out of the case, but you can adjust them in any direction. Looking at the exterior, it is matte black with the ARCTIC logo and branding on either side.

I see the black-silver braided 450mm tubing coming out of the radiator on the left. It’s a good length for most front installations. The tube measures 12.4mm in outer diameter and 6.0mm in inner diameter. These tubes come with aluminum case fittings that ensure a secure and leak-free connection.

The ARCTIC Liquid Freezer II 240 A-RGBs fans do not come with separate cables for PWM and RGB; instead, the fan connections are driven through the pump headers, and the connection is created by the manufacturer using the cooling tubes. Also, unlike other low-end AIOs, there is no fill port on either side of the radiator, and the cable management is also barely visible. 

Water Block And Pump

The pump head immediately stands out with its futuristic, robotic design — a departure from the norm. Notably, it integrates a fan essential for VRM temperature management. Unlike its non-RGB predecessor, the pump lacks RGB elements. The ARCTIC logo subtly marks both pump head flaps. With silver accents and a distinctive shape resembling a bird or jet between the flaps, it’s a uniquely styled component.

The pump head has two cooling tubes with secure chrome fittings, though they lack flexibility for installation convenience. On the reverse side, we see the same arrangement as the top, featuring the ARCTIC logo and output lines for PWM and RGB controls. Regarding cable management, the cooler excels as it requires only two connections for fan, RGB, and pump power, simplifying the setup process.

We can see the copper cold plate underneath the cooler pump head. It has a smooth finish and a generous surface area. There’s a protective peel on top of it, which is essential if you haven’t applied thermal paste yet. While the cold plate may appear slightly smaller compared to other coolers, it’s still compatible with a wide range of sockets.


The ARCTIC P12 PWM PST A-RGB Fans are included with the ARCTIC Liquid Freezer II 240 A-RGB.

Fan (Image by Tech4Gamers)

The front fans have a classic design with the company logo in the center and noise-reducing cushions. They offer vibrant RGB lighting with five white blades and require a 4-pin PWM connector and a 3-pin RGB connector. Keep in mind, the AIO doesn’t come with RGB controllers, so you’ll need to use your motherboard software or get a HUB for fan control. 

The four arms of the fan are curled in at the back, along with the ARCTIC emblem and certain power ratings. As for the speeds, the minimum is 200 RPM and maximum is 1800 RPM. Cable length isn’t critical in the case of the ARCTIC Liquid Freezer II 240 A-RGB because the connection is established with the pump headers through the tubing and all other connections are neatly in place, but if it is, the cables are quite short.


While reviewing the Arctic Liquid Freezer II 240 A-RGB, I was very worried about installation. However, the installation of the ARCTIC Liquid Freezer II 240 A-RGB is simple. Because the package does not include any installation guidelines, we are given a URL on the package to obtain the essential installation instructions. 

We’ll be installing the cooler on an Intel 115x socket chipset, so make sure you’re on the same page as us before proceeding, since installation for AMD and other sockets may change. Before you begin, make sure your CPU is free of any previous thermal paste by wiping it off with cotton and rubbing alcohol. With that out of the way, follow these steps for installation:

  1. Install the radiator in the desired direction of airflow onto the top or front of your case using the 8x screws and flat washers provided.
  2. Now place the insulating washers on top of the motherboard, surrounding the backplate screw holes.

  3. Place the backplate in the proper position, making that all holes are exactly aligned, once the insulating washers have adhered to the motherboard.

  5. Select the right mounting bracket for your CPU socket and use the two included mounting screws to secure it to your pump header. Ensure that both brackets are securely attached to the pump head and that the connection is upright.

  8. It’s time to connect the cables after everything is in its proper spot. Connect the 4-pin PWM connection to any available Fan header on your motherboard, then connect the 3-pin A-RGB header to an RGB header

Here are a few snaps of the impressive RGB lighting of the fans.


We tested the ARCTIC Liquid Freezer II 240 A-RGB on the Intel i9-12900K to test the cooler to the limits. The tests were conducted in the Thermaltake View 71t, which has 5 intake fans on the front whilst 3 fans are used for exhaust including the ARCTIC P12 PWM PST A-RGB Fans on top. We used the original MX-5 paste that came with the ARCTIC Liquid Freezer II 240 A-RGB in the box. 

Test System

The latest Intel Core i9-12900K will be our friend during the testing, the rest of the specs are as below;

Testing Methodology

In BIOS, we set the i9-12900k voltage to 1.15V, the P-Cores to 4.9 GHz, and the E-Cores to 3.9 GHz. By forcing usage of roughly 140W, we enable comparison with basic heatsinks. We then ran the test in Aida64 for 5 minutes with the processor and memory boxes turned on. Finally, delta temperatures between the ambient temperature and the related test are considered for the ranking.

The benchmarks were taken twice: once with the PWM settings and again with the fans and pump set to full speed.

Benchmark Results
