LEPA Vortex High Performance 140mm Case Fan with PWM speed control, LP-VX14P

There are a lot of cooling fans on the market, but after a ton of research I decided on Lepa PWM’s for nearly all the fans in my new rig; it’s a huge case and will include two 360 radiators, two 480 radiators, and over twenty fans. These have a versatile CFM/RPM/dBA performance range and an excellent hybrid design; featuring high air flow “propellers” with a static pressure enhancing "vortex" grill on the trailing edge (plus interior covers aren’t necessary).I’ll be using these in push-pull configuration; these non-LED Vortex models on the exhaust side are an exact specification match for the Lepa Casino's on the intake side (where they can show off their fantastic LED effects). The build is far from complete but even on the test bench I am very impressed with the performance I’m getting out of these; eight of them on a 480 at 1595 rpm and they’re not loud at all.

Works well. I added fans for increased airflow for a budget case. I also wear headphones and the noise it produces is it not an issue. The fan IMO isn't loud at all but i know some people can be very picky if they hear the any fan noise from the case.

Quiet and moves a good amount of air for the noise it makes.

I am very pleased with this fan! I am using it as an exhaust fan with 2 LEPA Vortex 14P fans in the front! They can really move air, quiet, and most of all 4pin pwm!

Nice and quiet and blows air what else could you want? Now to see how long it lasts running 24/7

The fan works but the noise generated by the fan is audible (not quiet at all but not very loud either). There are better choices out there. Will be returning this fan.

2 of these in my gaming case. They are quiet and the motherboard can very the fan speed for even less fan noise.

Muy buen abanico, silencioso grande y poderoso, no tiene leds ni otras cosas pero cumple su función, el único problema fue que desde que se compró no da las lecturas de velocidad correctamente.
