Introduction:

Today we have a couple of case fans from NZXT on our bench. These case fans are from their "Enthusiast" series which are built for gamers or anyone else who wants some high quality fans. The NZXT FX-120LB and NZXT FX-140LB case fans come with some cool features that you just don't see in other case fans. NZXT is well known for building all kinds of PC components like PC cases, PC case fans, fan controllers and many other PC peripherals.

A Closer Look:

The NZXT Enthusiast case fans are packaged as you would expect. They are in your standard cardboard box with some minimal graphics on them. Once you remove them from the box, you immediately notice they are not your usual fan. They have an extra wire, which contains a fan speed switch. NZXT has also given extra flexibility as the fan power wire can connect to either a 4 pin Molex or a three pin motherboard connector.  These cables have some nice sheathing on them.

The NZXT fans do come with a couple different options in terms of mounting hardware.  You have a choice of the standard screws or the rubber anti-vibration fasteners. The NZXT FX-120LB case fan comes with seven blades - a standard for 120mm fans I have seen. The NZXT FX-140LB case fan comes with nine blades - also a standard for 140mm fans.

The NZXT Enthusiast series 120 and 140mm fans have a three position fan speed switch built in. It can be set to L(low), M(medium) or H(high). You can choose the setting best for where it is mounted and how much air flow is desired. This can be done without using a separate fan controller thanks to this innovative design. The 120mm fan can be ran on the low setting at 1,000rpm on medium at 1,800rpm and on high at 2,600rpm. The 140mm speeds are a little different. The 140mm fan runs on the low setting at 1,000rpm on medium at 1,500rpm and on high at 2,000rpm.

Specifications:

As you can see above, both fans have a very similar maximum airflow rating (CFM = Cubic Feet per Minute).  The difference is the 120mm fan runs at 2200rpm in order to achieve this and makes more noise than the 140mm fan which runs 200rpm slower. 

On the next page we'll take a look and try and "test" a fan before we wrap things up with some final thoughts.


 

Testing:

My testing method for a case or heatsink fans is pretty straight forward. I simply install them in a case and see if there is any noticeable difference. After trying the NZXT Enthusiast fans in several different setting and positions, I discovered that the low and medium settings are barely noticeable. In fact they are not as loud as the stock case fans they replaced and move a little more air through my case. The high setting was definitely noticeable however. It was loud enough to drown out all the other fans in the case, but it did move a lot more air. If you are not worried about fan noise when they are set on high or are over-clocking your rig, this is not a problem.

Conclusion:

I found the NZXT Enthusiast fans - the FX-120LB and FX-140LB - to be high quality. The three position fan speed switch is unique and very handy when setting up the air flow in my rig. NZXT does warranty their fans for two years but with the fluid dynamic bearing and a expected life of 35,000 hours. You will not be replacing these fans any time soon. Overall, the NZXT case fans are a very good choice if you are looking to replace any fans in the future. If you are looking for some fan speed control without the use of a fan controller - these fans will make it happen.

 

Pros:

  • Fan Speed Switch
  • Fluid Dynanic Bearing
  • 2 Year Warranty
  • Molex and 3 pin connector

 

Cons:

  • None
