The following system was used to test the fans:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: NeoForza Faye 64GB DDR4 @ 3600MHz
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial P5 500GB
– HDD: GOODRAM IRDM 1TB SSD
– CPU Cooler: Cooler Master Master Liquid 240
– PSU: Seasonic Snow Silent 750W Platinum
– Case: be quiet! Silent Base 802 White
– Thermal compound: Noctua NT-H2
The testing of all fans is done with the i9 9900K CPU 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 Cooler Master Master Liquid 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 Akasa Soho AR 120 is a good mid-range fan that can work both as a case fan or as a heatsink & radiator fan. However, this fan needs to be priced lower to be competitive, especially when its price is close or even higher than the established fans from Noctua or be quiet!.
The Soho AR 120 is a good fan and has a pleasant RGB system that does its job without being obnoxious.
The best feature of this fan is the build quality which is on the same level as Noctua or be quiet! The fan frame is made from plastic but it is solid and has no flexing present. The same can be said for the impellers which are solid and retain their shape even at maximum speed.
In terms of the performance, the Akasa Soho AR 120 is on the same level as many mid and upper range fans that do not use specific bearings or technologies meant to increase the static pressure. However, with a speed of 2000RPM, the performance should have been better, especially on a radiator.
The noise output is ok for the most part, there isn’t much to say here as a fan that spins at 2000PRM can’t be silent, not without additional engineering and a higher price.
The biggest drawback of this fan is the price, at 30 or even 29 USD, it’s still more expensive than some Noctua fans, fans that not only perform better but are quieter and come with a better accessory bundle.
In conclusion, the Akasa Soho AR 120 is a good all-purpose mid-range fan that uses addressable RGB LEDs and is well built. The performance is on the same level as many mid-range fans and the Soho AR 120 can be used both on radiators and on cases. The biggest drawback of this fan is the high price which makes it a hard purchase.
