LEPA Vortex LPVX14P – Test and Review

LEPA Vortex series is a fan series featuring two models with vortex frame design made for best performance/silence/appearance balance:

  1. LEPA Vortex LPVX12P – which I have already tested in the past with dimensions of 120 x 120 x 25mm working at 600 ~ 1600±10% revolutions per minute with airflow level of 42.25 ~ 108.65m3/h, static level pressure of 0.66 ~ 2.18mm-H2O at noise level of 15 ~ 25dBA. The fan is PWM powered and regulated and rated with MTBF of  50,000 hours.
  2. LEPA Vortex LPVX14P – which I am going to test and review in this article with dimensions of 139.5 x 139.5 x 25mm working at 600 ~ 1200±10% revolutions per minute with airflow level of 54.49 ~ 106.65m3/h, static level pressure of 0.75 ~ 1.39mm-H2O at noise level of 15 ~ 20dBA. The fan is again PWM powered and regulated and rated with MTBF of  50,000 hours.

LEPA Vortex LPVX14P arrived to me in the pretty standard for the company carton package painted in standard black/grey/brown colours with a see through cut on the front panel, through which we can see the propeller shape of the fan, and a carton part covering the additional accessories. On the front side of the box there are some information regarding the product, while the full technical specifications are described on the back of the box.

After I took the fan out of the package I noticed that it offers absolutely the same frame and the propeller design as the smaller model from the series just working a bit differently…

So let’s check out the fan itself…

The bigger version of the LEPA Vortex series offers a very aggresive, again with lots of sharp edges semi-transparent black frame made of plastic, again including the channeling (Vortex effect) on the back side and that is actually a standard feature of the Vortex and Casino series. But what else is there to expect since both models are offering the same design with different performance.

LEPA Vortex LPVX14P is supplied with a transparent black propeller with 7 not very wide and average sharped angled blades, made to provide the best possible balance of airflow level, static level pressure, while operating at low noise level. Whether that is true, we will find out a bit later.

According to the official technical details LEPA Vortex LPVX14P is powered and regulated with a long 4-pin PWM of course sleeved in black cable.

LEPA Vortex LPVX14P’s standard package features:

  1. Four screws
  2. 4-to-4 PWM Pin power adaptor

Pretty simple package content I should say, but after all it is enough so the fan can be installed as a cooling unit for a CPU heatsink or as a case fan for boosting the airflow inside every modern case offering a 140mm case fan slot.

I believe the time for testing has arrived.

The tests will be conducted in my standard way. I will mount the fan and test it at 5V/7V/9V/12V and my goal will be to check the performance of the fan in real conditions. The product will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the tests can in no way be the same if the fan is mounted on a cooler or on the case fan hole of any modern computer case. I will measure the amount of air going through the fan for one hour and its speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.

And this is what the fan looks like installed on my test stand:

The test results are shown in the following charts:

The anemometer showed the following air speed:

After the fan was installed onto the stand and left to run for about 30 minutes at maximum speed, it was time for the tests to begin.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and LEPA Vortex LPVX14P made at least one full revolution at about 5V but the fan was rotating at only 180 revolutions per minute and was not able to provide a steady airflow.

Test at 5V:

At the first test conducted at 5V the model was not able to provide any stable airflow in fact the fan was rotating at only 180 revolutions per minute.

Test at 7V:

The second test, conducted at 7V made the fan rotate at 600 revolutions per minute with absolutely no noise coming out of the fan and providing airflow level of 28.8 cubic metres per hour.

Test at 9V:

At the third test, conducted at 9V the fan reached up to 975 revolutions per minute with airflow level of 51.84 cubic metres per hour. At the third test the fan remained absolutely silent.

Test at 12V:

The last test done at 12V made the fan reach its maximum performance with airflow level of 76.32 cubic metres per hour, while rotating at 1335 revolutions per minute. At this test the fan started generating a tiny noise coming out from the air passing through the propeller.

I am done testing, so let’s share my conclusions:

LEPA Vortex LPVX14P Performance:

I finished testing and reviewing the fan and all I can say is that all of the models from the LEPA Vortex series are made to be used as case fans installed inside every modern case to boost the airflow and keep all of the hardware cool and running and with its vortex effect I believe the best option for this product is to be installed as a front fan and cool every hardware component on its way. I can’t really recommend this model to be installed on a CPU heatsink since it offers pretty average airflow and static pressure. Well maybe for lower class CPU it will do the job but it will not handle anything more than that.

LEPA Vortex LPVX14P appearance:

LEPA Vortex LPVX14P offers absolutely the same desing as LEPA Vortex LPVX12P and seems both of the fans are typical case fans made with an aggressive look and with this colour scheme to be neutral when installed inside the case, which makes them the perfect choice for every modern or even modded case.

I believe LEPA Vortex LPVX14P deserves the following reward:
