The following system was used to test the fans:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: Ballistix Tactical Tracer 16GB DDR4 @ 2666MHz
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial MX500
– HDD: WD 1 TB Blue
– CPU Cooler: Cooler Master MasterLiquid 240
– PSU: Seasonic Snow Silent 750W Platinum
– Case: Phanteks Enthoo Luxe White
– Thermal compound: Noctua NT-H2
The testing of all fans is done with the i9 9900K CPU overclocked to 5GHz at maximum load with Intel Burn Test V2. All system fans and the tested fans are turned to their maximum speeds while the PC case has both side panels closed.
The 120mm fans has been tested using a 240mm CPU liquid cooler, the CoolerMaster MasterLiquid 240 at max. RPM.
The 140mm fans has been tested using a 280mm CPU liquid cooler, the NZXT Kraken X61 at max. RPM.
120mm Fan Performance
The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.
The Fractal Design Prisma AL-12 PWM triple fan pack, is available for approximately 80 USD or EUR.
The performance of these fans is good, the Prisma is truly an all-purpose fan, as it does a good job both when installed on a radiator and as a case fan. However, the radiator performance could have been better, and for less noise.
The noise generated is higher than the competition, with the peak at 42 db, however, there are no unwanted noises from the bearing system.
The addressable RGB system is very good, it offers vibrant colors and a bright overall illumination, without being overpowering inside the system.
The build quality is very good, the impellers and fan hub are made out of solid plastic which is semitransparent, to enhance the color and brightness of the LEDs. The fan frame is solid with little to no flexing present.
In conclusion, the Fractal Design Prisma AL-12 PWM is a good all-purpose fan, which offers a great addressable RGB system, with a good performance. The design of the fan is minimalistic and can be matched with any system, with ease.
There are two inconvenients with this triple fan pack, first of all, the price is on the high side on the market. The second is that the accessory department is truly lacking. There is no user manual offered, and no long screws for radiator usage.
