Introduction: 

There are 2 good reasons to upgrade your case fans, either the fans that came with your case are way too loud, or the fans that came with your case are now making a racket and need a replacement. We've had the chance over the years to take a look at a bunch of different aftermarket fans and today we've got a new competitor, NZXT.

NZXT is probably most well-known for their cases (which we have reviewed numerous times over the years), but they've also got a lineup of case fans to help get you a little extra airflow without making a whole bunch of noise. Today we are going to be looking at NZXT's FZ-120 and FZ-140 fans which both come in LED and Non-LED versions.

In order to see what the NZXT FZ-120 and FZ-140 are capable of we'll be comparing them to some other aftermarket fan's that we've reviewed in the past:

 

 

First Impressions:

It's pretty tough to get too excited about case fans, but overall I'd say my first impressions of the FZ-120 and FZ-140 fans was very positive. Neither of the models felt cheap or flimsy and thanks to the 13 fans blades that each of these models offer they look pretty aggressive.

As you can see in the first set of pictures, NZXT sent us both the Non-LED version of each fan as well as a couple that had LEDs built-in. Our FZ-120 has white LEDs and the FZ-140 has green LEDs.

Neither the FZ-120 or FZ-140 really offer much in terms of accessories, but you'll get 4 screws and a power adapter which should be everything you need to get started.

The Non-LED version of both the FZ-120 and FZ-140 are pretty standard looking other than the fact that they've got a ton of fins (13 to be exact). It has been interesting to see over the years as companies have experimented with more and less fan blades but as of right now 13 blades is the most that we've ever seen on a fan we've tested at BCCHardware.

The LED versions of both the FZ-120 and FZ-140 are pretty much identical to the Non-LED version except for the fact that the fan blades are clear and you've got 4 LED lights built into the frame of the fans. You can see in the picture below how the Non-LED and the LED versions of these fans compare.

There we go, that's what the FZ-140 and FZ-120 fans look like. Let's move onto the next section to see what these fans are capable of.

NZXT FZ-140 and FZ-120 Case Fan Testing:

As far as testing goes for these fans, we basically just plugged them in and saw what they could do.

In the next set of pictures you'll see the FZ-120 (White LED) and our FZ-140 (Green LED) fans in action. I was going to include some pictures of the Non-LED fans in the dark, but let's just say you couldn't see much.... (sorry, bad joke).

In the next section we'll put these fans up against some other case fans that we've tested.

 

Test Setup:

For comparison purposes we've put the NZXT FZ-140 and FZ-120 fans up against some others from Noctua and Thermaltake as well as a generic 120mm case fan that we pulled out of an cheap case.

The biggest thing that sets NZXT apart from the competition is that their fans are significantly cheaper than the others. The FZ-120 Non-LED version runs seven dollars cheaper than any other of the fans (which adds up when you are buying 3 or 4 fans at once).

Now there was one statistic that really got me thinking, and that would be input power. According to the numbers on the boxes of these fans, most similar to each other, but I started to wonder just how accurate these numbers were.

To test thing myselfI hooked up all of the fans to a Kill-A-Watt power meter to see just how much power they were actually drawing at full speed. The results were surprising.

 

  NZXT FZ-140 Fan NZXT FZ-120 Fan Noctua NF-F12 PWM Noctua NF-S12B FLX Noctua NF-P12 Thermaltake ISGC Fan 12 Generic 120mm Fan
Actual Wattage 6 Watts (Non-LED) 8 Watts (LED) 6 Watts (Non-LED) 7 Watts (LED) 1 Watts 2 Watts 2 Watts 2 Watts 8 Watts

 

Now to be fair, all of the fans were higher in "Acutal Wattage" testing than advertised, however, the NZXT fans were all at least 3 times higher than advertised on the back of the packaging. Both of the LED versions added an extra watt or two to the readings, but in the end both the 120mm and 140mm NZXT fans were pretty close to the generic 120mm fans power usage.

Now just to do the math, let's say we put 3 fans in our case (which would be a pretty typical fan setup). If I were to calculate the power usage based on my last months power bill which cost me $0.08 per kWh, using 3 NZXT FZ-120 LED fans would cost me approximately $14.68 CDN to run these fans 24 hours a day for a year. In comparison to run 3 Noctua NF-S12B FLX fans (or any other 2 Watt fans) would cost me approximately $4.19 per year.

I've done up an additional chart to show how much it would cost to power each of these fans 24 hours a day for 1 year (with a power cost of $0.08 kWh - your power costs may be higher or lower) (you can calcuate your own power usage here).

 

  NZXT FZ-140 Fan NZXT FZ-120 Fan Noctua NF-F12 PWM Noctua NF-S12B FLX Noctua NF-P12 Thermaltake ISGC Fan 12 Generic 120mm Fan
Approximate cost to power fan 24 hours a day for 1 year ($0.08 kWh) $4.19 (Non-LED) $5.59 (LED) $4.19 (Non-LED) $4.89 (LED) $0.70 $1.40 $1.40 $1.40 $5.59

 

How slow does it have to be in order to be virtually silent?:

Biggest question we get about fans would be, is it silent? Chances are good that all of these fans would be pretty much undetectable in most peoples systems even when running at full speed (due to other components producing more noise).

For our testing we have hooked each one of these fans up in a quiet room to see just how slow they would have to spin before we couldn't hear them anymore. While this isn't the most scientific method of testing, it does give us a pretty good idea of how quiet each of these fans are.

During testing we hooked each fan up an adjustable fan controller and manually tested their speeds with a digital tachometer while standing approximately 2 feet away from the fan. Here are our results:

 

  NZXT FZ-140 Fan NZXT FZ-120 Fan Noctua NF-F12 PWM Noctua NF-S12B FLX Noctua NF-P12 Thermaltake ISGC Fan 12
Speed at which fan became virtually silent (in a quiet room) - Higher is Better  950 RPM
 1000 RPM
1050 RPM 900 RPM 950 RPM 900 RPM

 

If you have an overall very quiet PC and would like to make the NZXT FZ-140 and FZ-120 completely unnoticeable you will want to hook them up to a fan controller so that you can slow them down a little bit.

Some of the other fans we've tested feature manual fan dials or PWM control (ability to automatically spin up or down based on temperatures), but the FZ-140 and FZ-120 fans have neither and will require some type of fan controller if you don't want them to spin at full speed all the time. 

 

 

 


 

NZXT FZ-140 and FZ-120 Case Fans Final Thoughts:

We've had the chance to take a look at a pretty wide array of aftermarket case fans over the years at BCCHardware so when NZXT offered us the opportunity to review their new FZ-140 and FZ-120 fans I was very interested to see how they would compare to the others I'd taken a look at over the years.

The cost of these fans is really what sets them apart from the other fans we tested them against. The 120mm Non-LED version has a MSRP of $12.99 compared to the MSRP of $19.99 that the others we tested had. Basically you could buy 3 of the NZXT FZ-120's for almost the same price of 2 fans from the competition. One reason for them being less expensive than the others could be the fact that they do not offer any type of fan control built-in (PWM or other manual method). If you are planning on hooking these fans up to a fan controller they will do the job nicely.

The biggest drawback I could find with the FZ-140 and FZ-120 fans would be their power usage. The NZXT FZ-140 and FZ-120 both consume slightly less power than generic fans did, however, when compared to other aftermarket fans they consumed up to 3x more power. If you plan on using these fans 24/7 and plan to use 3 or 4 of them inside you case it might be worth calculating your power usage (like we did in the testing section of this review).

 

As far as build quality goes, both the FZ-140 and FZ-120 from NZXT are very sturdy and I really don't have any concerns in the build quality goes. These fans all carry a 2 year warranty and are rated to last up to 40,000 hours (or 1670 days).

At the end of the day we were very happy overall with both the NZXT FZ-140 and FZ-120 case fans. If you are looking to upgrade your case's cooling or want some high quality replacements you can't go wrong with the FZ-140 or FZ-120 fans from NZXT. We really like the fact that you can get either of these models in standard Non-LED or if you want to add some color to your case you can get a bunch of different LED-colored options. Both the FZ-140 and FZ-120 case fans scored very well in our testing and have easily earned our "Editor's Choice - Silver" award.

 

    

Pros:

  • High Quality
  • Lower MSRP than the competition
  • Offers multiple LED Colors (Blue, Green, Red, Orange, and White)

 

Cons:

  • Higher Power Consumption than the competition
