Recently we had a chance to look at a cool looking case fan.  We have the Spectre Pro LED 120mm fans by Bitfenix on our bench today. These fans are a part of their performance series.  They come in different colors with or without lights (red, blue, white).  I will be testing with the blue LED fans as they match my PC color scheme.

The Spectre Pro LED 120mm fan has nine blades that have been reinforced with ridges on the fan blades to make them less prone to vibrations while spinning at high RPMs. The casing is also built more rigid to help ensure less movement when fastened in place.

In each fan package you'll get some great accessories with the Spectre Pro fans.  They include four rubber mounting insulators, four mounting screws, a voltage reducer connector and an extension cable to run on the motherboard.  For a fan, they have some nice features.  If possible, you'll be happiest if you use the rubber "anti-vibration" rivets as they will help reduce overall system noise due to vibration.



On the next page we'll look at the fan specs before we jump into installation and testing.



In the section below, all of the features and specifications have been taken directly from the BitFenix website and the product page for these fans.  We've only included the information below for your convenience.  If you want up to date and complete features and specifications, please refer to the manufacturers site.

High Pressure/CFM Design
Engineered for maximum pressure and airflow, Spectre Pro LED delivers a torrent of air that will keep your system cool even when the action heats up. Performance freaks and water cooling enthusiasts are going to love Spectre Pro.

Dual Frame Construction
Using a dual frame construction, Spectre Pro LED fans not only offer aggressive looks, but also vibration dampening properties, helping to keep noise levels in check. In short, our Spectre Pro LED Fan Series looks different because it is.

Reinforced Fan Blades
High rotation speeds can actually warp fan blades while in motion, resulting in more turbulence and noise. Spectre Pro LED features reinforced fan blades that resist warping even when spinning at high speeds for maximum cooling performance.

Focused Airflow
All the airflow in the world won't do you any good if it can't reach your system's hotspots. The special curved design of Spectre Pro LED fan blades and cage directs airflow in a focused column, minimizing diffusion and allowing cool air to reach your components.

Silent Operation and Long Life
Like our Spectre™ LED Silent Fan Series, our Spectre Pro LED features the very same fluid dynamic bearing technology for minimum noise and maximum operating life.

Multiple Colors Available
No two setups are alike, which is why Spectre Pro LED comes in a variety of LED colors. Spectre Pro LED's inner ring is also color matched to the LED color for a unique look.

On-the-Fly Light Switching
Spectre Pro LED borrows the on-the-fly light switching technology from our original Spectre™ LED Series, which allows you to turn the fan lights on and off with the push of a button using compatible BitFenix chassis and accessories.

Excellent Extras
Included with each Spectre Pro LED Fan are some thoughtful extras that help you keep noise levels as low as possible. Four Anti-Vibration Rivets help further deaden noise-making vibrations, and for even more noise control, install the included Low-Noise 7V Adapter. Get more with Spectre Pro LED.

On the next page we'll cover installation and testing of these fans as we wrap things up.



Installation in any case will vary.  In my case installation wasn’t so as easy.  I had a little more work as I have the Antec Twelve Hundred case.  Fan installation in this case is difficult no matter what fan I would have put in the case - not just the Spectre. As you can see in the image, I had to pull the tray out of the case and detach the front clip from the tray to reveal the screws that hold the fan in.  Once these are disconnected, I can place the new fan in this tray.  I had to repeat this step three times and the fan fits in nicely with no problems.

As you can see below, the Spectre fans look much brighter with four LED lights - one in each corner as opposed to the stock fans with only three LEDs per fan.

Before we jump into testing, we'll cover some basic systems specs.

System Specs:

  • Antec Twelve Hundred Case
  • Asrock 890FX Deluxe 4 Motherboard
  • AMD Phenom ll x4 Black Edition
  • Thermaltake V1 AX  HSF
  • 8G G.skill RipJawz Gaming Series DDR3
  • XFX radeon HD 5870
  • Kaze Master ll Fan Controller
  • Windows 7 Ultimate

The first thing I noticed when testing with a fan controller was that the higher the RPM on the fan, the brighter the LED lights go.  Now with all three fans running at the 1200rpm speed, (max) it is still nice and quiet - nearly to the point of silence.  When comparing these fans to the original setup I had, I'm not thinking of updating the rest of my fans in my system to the Spectre Pro series.  BitFenix can hook you up with 140mm, 200mm, and 230mm fans in addition to the 120mm version we have on our bench today. 

I have a lot of fans in my system and I had to really turn down every other fan and listen really close to hear these fans at all.  At about 1100 RPM I could start to hear them above the system noise in my PC.  When comparing these to the original stock fans - all three Spectre fans running at 1200 RPM are still much much quieter than having one of the originals running full blast.



The Spectre Pro Blue LED 120mm Fans look great.  They are bright and really nice and quiet.  They are also very well built and strong looking thanks to the ribbed fins. The fans are really quiet even with three of them running and are well worth $14.99 for the 120mm fan.


Installing the fans was a little difficult and a long process as I had to repeat the steps three times.  This involves pulling the fan tray out of the case and detaching the front clip to get at the screws to take the fan out of the rack and then putting the new Spectre fan in its place.  Again, this is system dependent, and in my system - it sucked.  In many other cases, installation will be simple and fast.

I was really impressed with the performance of the Spectre Pro 120mm fan at 1200 RPM.  Even wide open, it is still virtually silent.  In order to hear it at all, I had to turn down all my other fans and listen closely.

I would recommend the Spectre Pro Fan to anyone that wants to improve the air flow in their system and keep things nice and quiet at the same time.  You won’t have to turn up the volume of your games or music in order to drown them out as these fans are very quiet.



  • Looks great
  • Really quiet
  • Reasonably priced


  • Nothing
