PC cooling is at the heart of the PC Master Race. When it comes to longevity of the hardware particularly the CPU the users tend to invest in a good cooling solution. These days there are a variety of coolers available in the market ranging from simple air coolers to the CLCs to custom loops.

The air coolers tend to be bulky and taking up much space. This puts pressure on the motherboard’s PCB and on the CPU as well. Skylake was one of the examples where many damaged CPUs were reported due to the sheer weight of the cooler. Not to mention the compatibility issues of the air coolers with RAM, the first PCIe slot and the chassis itself. AIO/Hybrids/Custom Loop would clear that space around the CPU socket, but many users avoid them for the fear of leakage.

Today I will take a look at the Aigo RGB 120mm A-Series fans. A pack of three fans was delivered to be reviewed. These are the 120mm fans having a ring around the main frame with the LEDs in it. With average on-board specifications, can these fans drive your cooling needs? Time to find out.

Packaging and Unboxing

The fan comes in a cardboard box with colorful picture in the background. The front cover of the box has the picture of the fan on it. RGB is printed on the bottom side. Main language is the Chinese on the box.

The backside has the specifications of the fan written in the tabular format. The company information is printed on the bottom side.

The left and the right sides of box have Aigo printed on these. The opening cover side has the black color background with aigo printed in the middle in the white color.

Each box has four standard M4 screws and the fan inside. There is another plastic container having the controller and the hub in it.

Closer Look

The design of these Aigo fans is quite different from the trasditional 120mm fans in the market. This fan has 7 black colored large sized blades which are angular. There is a sticker on the motor hub top. Aigo is printed on the sticker. What makes this fan different is the inclusion of the large size translucent ring on the frame. The ring has 7mm depth to it and it has a layered design with the inner side towards fan’s blades being on the inset. The side of the fan has 25mm height. Out of this the ring takes up to 13mm of the space. Remaining portion is the fan’s actual main frame. From the corners, the fan frame has full 25mm height. The ring blade runs inside the corners of the fan frame. There are 21 LEDs inside that ring which are not independent.

There are white color anti-vibration silicon pads on the corners of the main frame which is a good thinking by the manufacturer. The fan blades have less length as compared to the standard 120mm fans which is understandable due to the inclusion of the 7mm ring inside the main frame taking that space. The main frame of the fan is made of the plastic. The fan does not give any poor quality impression and is rather at par with the majority of the other 120mm fans in the market.

Let’s take a look at the backside of the fan. There is another sticker on the motor hub with the aigo printed on the top side. Malaysian language is used to list the certain features of the fan like its RGB functionality and the dimension. There is a 4-arms assembly holding the fan’s motor hub and it is connected with the main frame. The length of the cable is approximately 280mm. The interface is not PWM as the cable has 6-pins format and it can’t be connected on fan header of the motherboard. It needs to be connected with the provided controller hub.

The fan has the rated speed of the 1500 RPM with ±10% variation. I was not able to measure the speed due to 6-pin format of the power cable. The 2 wires are powering the fan while the 4 wires are powering the LEDs inside the ring. The rated air flow is 33 CFM on this fan which is on the lower side. The sound level is rated at 23.5 dBA. With just 1500 RPM and 33 CFM, I was expecting this number to be lowered which is not the case. The fan takes 12V DC with 0.35A and 4.2W. The fan features the hydraulic bearings with the MTBF of 20000 hrs.

Let’s take a look at the controller and hub. The hub PCB has 3 6-pin headers for connecting up to 3 aigo RGB fans with it. There is a 4-pin header as well which is for a RGB LED strip should the user want to sync the Chassis lighting with these fans. The controller is using a Molex connector to power it up. There is a two pin header which is used to connect the controller cable. The controller cable is simple. The controller is a single press button type. A button is pressed each time to change the color effect on the fans.

RGB Lighting

The RGB lighting is pretty simple on these fans. It has 4 modes in total which can be accessed using a single button interface on the controller. The button acts like a toggle for it has to be pressed each time to change the effect.

There is a static mode on the fans with only four colors available for the users. These are the Red, Green, Blue and the White colors. The colors are uniformed across the ring and diffuse pretty well to give much pleasant lighting. These colors are not that bright as we have seen on the Corsair HD120 RGB fans. There is no mechanism provided to control the brightness of the fans. I like the white color effect on these fans as white is being represented as pure white whom we seldom see.

The other mode has fast blinking and rotating colors effect on it. The first color blinks and the other colors are changed with the rotation across the ring. Whole action is completed much faster.

Another mode is the slow blinking and color changing one. The fourth mode is the color changing mode.

User can turn the LEDs completely off. Even with the LEDs off, the fans looks give good bold looks.

Performance Testing

Due to the 6-pin format, I could not check the speed of the fans to verify the rated speed of the 1500 RPM ±10%. The Perfect Prime’s Anemometer was used to check the air flow of the fans. Two fans reached the 38CFM while the third one did the 40 CFM which are above the rated 33CFM on these fans. There is no static pressure rating provided by the manufacturer which gives a slight hint that these fans are suggested for the air flow in the chassis.

Test Bench

To check the thermal performance of the fans, they were connected with the Alphacool Eisbaer 360 CPU cooler. Here is the test bench configuration used for this testing:

  • Intel i7 6850k
  • Asus Rampage V Edition 10
  • Ballistix Elite 4x4GB @ 3000MHz
  • Alphacool Eisbaer 360
  • Samsung 840 EVO 250GB SSD
  • Corsair AX 1200i

The CPU was tested on the stock clocks I,e 3.6GHz with turbo boost of the 4.0GHz at 1.16V VCore. The Asus RealBench version 2.44 was used to stress the system and HWinfo 64 version 5.58-3255 was used to monitor the temps. The average of all the cores’ temps was taken and the ambient temp was subtracted to get the delta temperatures.

The CPU was overclocked to the 4.3GHz using 1.350V VCore. The same process was repeated as stated above to get the delta temperatures.

The comparison is between the Eiswind fans the aigo RGB fans. Here is the result:

Test Result

At the stock clocks i.e 3.6GHz with the turbo boost of the 4.0 GHz the maximum temperature using the Aigo RGB fans was 26°C whereas the temps using the Alphacool Eiswind fans were 21.5°C. There is a difference of the 4.5°C. Though the difference is giving bit warm temperatures, but not that much and given the acoustic level, it is not that bad at all.

With the i7 6850k Overclocked to the 4.3GHz using the 1.350V Vcore the temperature difference between both fans is 4.8°C with the Aigo fans being on the higher side of the temperatures.

As there is no control over the speed of the fans, there was no way to check their sound at the idle levels using PWM. Fans were giving 26 dBA collectively which is a good number after all.

Conclusion

The Aigo RGB 120mm A-Series fans are 120mm fans with the dedicated controller hub to connect up to 3 fans to it. The fans are rated at 33 CFM though in my testing the fans were doing between 38-40 CFM. The rated sound is 23.5 dBA. With all three fans in the action, max sound recorded by the sound meter was 26 dBA. The fan takes 4.2W of the power using 12V DC at 0.35A. Each fan has 6-pin power cable. Two wires power the fans while the 4 wires power the LEDs.

These fans have a 7mm thick translucent ring around the main frame of the fan. This ring has the height of the 13mm. There are 21 EGB LEDs inside this ring. These LEDs are not independent and offer a very basic level of RGB lighting. They have only four colors in the static mode, which are the Red, Green, Blue and the White. There are three other lighting modes which are fast blinking and rotation, Color Shifting and Normal Blinking modes. The ser can turn the LEDs completely off, which is a handy feature.

There is a hub and the controller to connect these fans to and control the lighting on these fans. It uses a Molex connector to draw power. Up to 3 fans can be connected with it. There is a 4-pin header on it as well to connect the RGB LED strip which is very thoughtful on the designer’s part as it allows the users to sync the Chassis lighting with the fans lighting and use the same controller to control the lighting effect.

The thickness of the ring added subtle looks and feels to the fans. The colors are not that bright enough to tease the users and the color diffusion is right excellent. Even with the lights powered off these fans offer the bold looks which are subtle and pleasant.
