Recently, we received the new fan pack, Jupiter AJ120, from InWin. This package includes 3 high airflow case fans, some anti-vibration stickers and a SATA powered RGB controller. The AJ120 series still maintains the daisy chain design, and come with a built-in RGB extension cable to reduce the difficulty of wiring, the ARGB fans supports ASUS AURA, Gigabyte RGB Fusion, Asrock Polychrome SYNC and MSI Mystic Light. The new EPIC PC case fan test bench will be used to measure the performance.
So let’s dig in the details.

Product Unboxing
Package Appearance

These fans are wrapped by a thin-layer of transparent plastic, ARGB 3 pins extension kits and some case screws are included
ARGB controller and the anti-vibration pads
Product Analysis
The AJ120 main looking
7 half-transparent blades without Diversion grooves but with trim design
The square shell is made by PBT
The Fan I/O includes a 4-pin PWM header and a 4-pin extension header
The RGB I/O includes a 3-pin ARGB 5V Header and a 3-pin ARGB 5V Header extension
This is a very useful and smart design
Colour Aesthetics
The RGB effects from InWin official website
The RGB effects we tested
The overall RGB effect is good, the fan blades are semi-transparent but the light conductivity is normal, the colour-missing is sometimes missing in the middle of the fan blades during high-speed rotation. The LED light balls are hidden inside without being exposed, and the light guide of the inner and outer rings is fairly even, with a thin-layer ring effect.
Test Bench Introduction
Before the test, we are introducing the EPIC PC FT-MKI Fan tester.
Currently, this tester can measure the blowing speed and pressure. We are going to add more functions such as RGB socket, Radiator pressure support, voltage adjustment and temperature measurement in a future upgrade.
This tester includes a STW 4-channel Main PWM Fan controller with temperature sensors
The digital screen is separated into two areas: LEFT – FAN SPEED | RIGHT – TEMPERATURE
If a fan is connected to the header 1, these knobs are used to control the fan speed from 0% to 100%
A Professional PM6252B Anemometer from PEAKMETER is the Main Fan tester
The Anemometer is used to test the fan pressure and power

Air Flow Benchmark
Test room temperature : 21℃±2℃
Test Fan Model : InWin Jupiter AJ120
Test Fan Speed RPM : 1830 RPM
Under the Flow test, this InWin AJ120 has 70.30 CFM under 1830 RPM
Test Fan Flow CFM : 70.30 CFM
Test Fan Pressure : 0.03m3/s
These results perfectly match the official specification. We are satisfied with the testing results.
SUMMARY
This is our first test of a case fan. More tests such as wind noise, wind temperature, will be added in the future.
InWin AJ120 can reach a full speed of 1830 RPM and has an air volume of 70.30 CFM. As a case fan, this result is already excellent.
For the price, only AU$59 for a pack of 3 and ARGB controller included, it’s extremely valuable, even a Coolermaster MF120R ARGB fan is AU$25 each without extra accessories. If you have any powerful ARGB fan controllers, it’s easy to control the AJ120 with fancy appearances.
EPIC PC RATE SCORE: 82.5/100
EPIC REWARD: EPIC RECOMMENDED, BEST VALUE
