The Vortex Fan Aluminum model has been tested using a 280mm CPU liquid cooler, the NZXT Kraken X61 at max. RPM.

CPU Temp. – 140mm fans



The noise level was measured at two RPMs and at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.



6. Final thoughts

The Prolimatech Vortex Aluminum Fan stands out by using an alloy of aluminum in the construction of the blades, thus offering a new perspective on the materials used in the construction of fans.
During testing the fans performed very well, the only drawback being the high noise level when the fans are at their maximum speed. The noise level can be reduced by using one of the low-noise adapters included in the accessory bundle.
The price of this fan is in the same segment as fans from manufacturers such as Noiseblocker or Noctua.
In conclusion, besides its nonconformist design and good performance, the Prolimatech Vortex Fan Aluminum model comes accompanied by a comprehensive accessory bundle.
