A new name on the PC component market, LEPA has been producing computer cases, power supplies, peripherals and fans since 2011. We’ll take a look at the VORTEX (LPVX14P) model today.

The fan is packed into a small cardboard box with a transparent front, so you can see the impeller.

Product specs and key features are listed on the back of the box. An adapter cable and self-tipping screws are included with the fan.

The VORTEX (LPVX14P) is manufactured in China and costs $16, which is quite a lot for a newly-created brand. The warranty period is 1 year.

The 7-blade 127mm impeller is shaped similarly to the Xigmatek XLF-F1253 but has longer and larger blades due to the larger form-factor.


The fan owes its original appearance to the grid on its back whose spokes are curved into the opposite direction relative to the impeller's movement. This results in a focused air flow as demonstrated by the manufacturer in the following clip:

The speed of the fan is PWM-regulated automatically in a range of 600 to 1200 RPM. The manufacturer declares an air flow of 32.1 to 62.7 CFM at 15 to 20 dBA of noise.

The bearing type is undisclosed in the specs but its service life of 50,000 hours implies a fluid dynamic bearing or a sleeve bearing with an extended service life.

The motor is only 47 mm in diameter, which isn't large for a 140mm fan. The fan’s model name, voltage and current are indicated on the sticker.

The sleeved cable is long at 480 mm. It has a short adapter to plug into a PATA power connector.
