Compared to the Spectre Fan Series, the Spectre Pro PWM comes with an all-new design and enhanced performance. The high-pressure CFM design is controlled by PWM technology for finer speed control - perfect for high-performance CPU coolers. Its unique dual-ring construction helps to dampen vibrations, resulting in less noise. Reinforced fan blades prevent warping at high RPM levels, while focused airflow ensures that cool air can reach all of your installed components. With FDB technology for low noise and long life, and availability in both solid black and solid white variants, the Spectre Pro PWM is the new gold standard in performance CPU-cooling fans.

  • newegg PWM Technology True to its namesake, Spectre Pro PWM uses pulse width modulation technology to adjust fan speeds. This technology enables your system to control your cooling with much greater precision than conventional linear voltage fans, making them perfect for CPU coolers.
  • newegg High Pressure/CFM Design Engineered for maximum pressure and airflow, Spectre Pro PWM delivers a torrent of air that will keep your CPU cool, even when the action heats up.
  • newegg Dual-Ring Construction With its dual-ring construction, Spectre Pro PWM fans not only offer aggressive looks, but also vibration-dampening properties to keep noise levels in check.
  • newegg Reinforced Fan Blades High rotation speeds can actually warp fan blades while in motion, resulting in more turbulence and noise. Spectre Pro PWM features reinforced fan blades that resist warping, even when spinning at high speeds for maximum cooling performance.
  • newegg Silent Operation and Long Life The Spectre Pro PWM features fluid, dynamic-bearing technology for minimum noise and maximum operating life.
  • newegg Two Color Versions No two setups are alike, which is why Spectre Pro PWM comes in both solid black and solid white versions.

4 out of 5 eggsPretty good airflow

Pros: Good airflow, decent price. Still can't seem to find any large fans with airflow comparable to high end 120mm fans.

Cons: Couldn't figure out how to use their screwless mounts. Ended up just using the usual self-tapping screws.

5 out of 5 eggsRecommended!

Pros: Four of these fans keep my hardware cool in my home network file server.
Fairly quiet for the amount of air they move, I recommend these fans for
use in cases where cooling is a priority over low noise.

Cons: None

Other Thoughts: These fans have four pin plugs for PWM control.
Make sure your motherboard supports this type
of fan, before buying them.

1 out of 5 eggsAbysmal BitFenix customer service.

Pros: PWM control; other than this, I cannot think of any other advantage.

Cons: Exorbitant price; and incredibly poor (in fact, total lack of customer service).

Other Thoughts: I bought about 20 of these fans. One of them failed DOA. Unfortunately, I did not test it until after the 30 days of my ordering for these fans; so, Newegg would not RMA it! I contacted the manufacturer for warranty work- BitFenix through a trouble ticket, I am still waiting (twiddling my thumbs, for a good measure) for those guys to respond to my repeated inquiries. The total lack of customer service should dissuade customers from ever dealing with BitFenix products.

2 out of 5 eggsfAILS TO LIVE UP TO HYPE

Pros: Can move air.

Cons: I purchased 4 of these fans for a Fractal Midi Arc XL. The lowest speed attainable is 800 rpm. Others, 900 rpm, others 1000 rpm. I'm not sure if this is their typical quality control or not. I read that they were supposed to be able to go down to 500rpm, no way. Then again one reviewer claimed he was missing his low voltage adapters, I had none. I have used these fans both off the motherboard and off of Bitfenix's RECON fan controller. Next time (or as soon as I can spare the cash) I will spend a little more and buy Noctua. It's not like these were cheapo fans on a closeout, they should ALL work as claimed.

Other Thoughts: At this point it appears that the recon fan controller is having issues as well. It doesn't change one word I wrote, it compounds the problem, now one fan will only be full on 1800 rpm or off. Support was contacted, time will tell. Recon is 2 months old.

4 out of 5 eggsExcellent case fans

Pros: PWM allows for very lower RPM when not needed; very quiet for airflow.

Cons: They are a bit pricy for a case fan, as good as they are (I got mine on sale at a price I think is a far better value).

Other Thoughts: I got six to fill out a Corsair 750D case that has a dual CPU + dual GPU setup - even with the system at full load I cannot hear the fans over ambient.

One egg docked for price. I think they might be slightly overpriced by a dollar or two.

5 out of 5 eggsGreat for Kraken X60

Pros: Great fan and specs. Went from 4 1300rpm fans (that were purchased on here) to these and the temps have improved quite a bit. I'm using the exact same fan profile within the kraken software and the liquid temp has dropped 10c and core temps have dropped 2-3c on an I7 3930k. Very impressed with these fans. I have ordered 4 more for my other rig.

Cons: Only con I have is the fact I was shorted a low voltage adapter. I was planning on using them for another project but oh well.

Other Thoughts: On a side note: They are a little noisy at full speed, but its air flow causing the noise. I can live with noise when I'm getting the cooling performance I was looking for.

5 out of 5 eggsgreat fans

Pros: Impressive air flow for the noise they make.

Cons: Nothing

Other Thoughts: People say the fan blades break and I think I know why. The blades them self are thinner and are made out of stiffer plastic that doesn't bend when you push on it it just breaks. I'm guessing that the thinner blades are the main reason these fans have one of the best cfm to db ratings I've seen.

5 out of 5 eggsSturdy, Quality Fans for a Rad

Pros: -Great balance of static pressure, air flow, and noise
-Quality feel

Cons: -As others have said they are a bit pricey but you get what you pay for, I'm not really complaining

Other Thoughts: I'm using a pair of these as push fans for my Corsair H110 closed loop liquid cooler. They have dropped my CPU temps by 2-3 degrees C across the board. These feel like high end fans with a nice texture and sturdy construction. They can make a bit of noise at high speeds but turning them up with a fan controller has a satisfying umf to it. They wind up quickly and with a lot of torque. The noise sounds and feels like just a lot of air being moved rather than rattling or whining or any other annoying sounds. The fans that came with the H110 are **** in my opinion. They make a lot of rattling noises at higher speeds. These BitFenix fans seems to do the job nicely, though. I'm ordering more for my next rad. I would definitely recommend these fans but you may want a fan controller to make full use of them.

5 out of 5 eggsRelease the Kraken

Pros: Its a fan.... read the specs and you will be fine.

Cons: None so far. Maybe people just don't know computers as much as they should? (not bashing other reviewers)

Honeslty though, unless the fan doesn't work, there really aren't any "cons". People like to nit pic computer gear to death. Did it do what it said it would do? Were the specs to your needs?

Even if a fan comes to you and it doesn't work, newegg will handle these things and send you a new unit most of the time, as long as you didn't break it because you don't know what your doing.

Other Thoughts: I bought these fans as a "performance boost" to go with the NZXT Kraken x60.

The stock kraken fans at max output 98.3 CFM, and have a pressure of 2.2mmH2O.

The BitFenix Spectre Pro PWM fans are 122.2 CFM and have a pressure of 2.8mmH2O.

Now I am NOT saying that you get said pressure with said CFM at the same time. On the contrary, CFM is like saying "unrestricted" and "pressure" is the ability to push what the fan can through a restricted object.

By upgrading I now have 2.8mmH2O of pressure, a .6 increase, as well as 4 fans as apposed to only 2 that come with the unit. On that note getting 2 more NZXT Kraken fans was an option for my push&pull however, I will get better performance from the BitFenix then I would have from the stock kraken fans.

I looked at other fans like the BGears 140 which can do 3.0mmH2O but not only are the reviews horrible bad, I've had used BGears before and I will never use them again, regardless of stats. This is my first BitFenix buy, so we shall see if they are any good over time. I was going to get the Rosewill (newegg house brand) 140mm hyperborea, they have only 89.55 CFM on top of the 2.7mmH2O. If your smart you would see WHY the BitFenix has the upper hand, higher CFM with slightly higher pressure. BOTH MATTER.

I currently have an Antec Kuhler 920. The stock fans are 110CFM and 3.26mmH2O(full duty cycle) according to Antec (I emailed them.) Everyone told me to upgrade to Corsair SP120's because they are quieter and preform better. When looking at the stats, this made no sense.

At the time the PWM version did not exist, they only have the SP high performance and SP quiet performance. I got the high performance. Said specs were 62.74 CFM with pressure of 3.1mmH2O. Those stats are HORRIBLE to the stock antec fans, yet each review I saw of "switching to corsair fans" showed cooler performance. BULL. My stock temps are 28c-35c depending on room temperature, and 35c-40c max load depending on room temp. With the corsair "better" fans, I was at 35-40c idle and 50c load. Then again I didn't know much about fans. I now pass this knowledge to you......

Don't believe the hype, BOTH NUMBERS MATTER (mmH2O and CFM). If you are building a water cooling unit or getting an AIO like the Kraken or other brands, don't be fooled by review websites. Most likely they only tested the unit on its basic settings, which let the fans run really quiet 60% of the time and only really "ramp up" to full when "oh my were getting hot jim". If you are a true ENTHUSIAST, there is no such thing as "quiet performance" only "performance." As far as loudness is concerned (DB) the only thing that matters is the performance. I see people complain their gear runs hot and I laugh when they state what they built with (not the parts, the cooling options and expensive "fancy" cases.) Even the Noctua fans are currently the "top dog" when they are GARBAGE when you start looking at the specs.

Happy New Year, Mer

3 out of 5 eggsOverhype

Pros: It does move a decent amount of air. I'm just guessing but it seems like it moves 70 cfm at 5 volts. High static pressure, good for radiators.

Cons: I bought a few cougar fans so I might be biased a little.

I feel its way over hyped.
There is no dampening. The dual ring is just plastic on plastic and just another potential rattle point. No rubber mounts.

Blade warp? Come on. If they used slightly ticker plastic the blades wouldn’t warp anyway. Also feels like the blades might pop off easier than most other fans. I honestly don’t think the fan spins fast enough to cause blade warp unless they used paper thin plastic for the blades.

Its not really that quiet. But it does have higher static pressure. Tolerable.

Other Thoughts: its probably best to stick with 120mm fans if you want something high performance. Lots of industrial fans that move 200+ cfm. Smaller fans also have better static pressure than larger fans. Larger fans are quieter and move more air when they aren’t blowing through fins though. Bigger fans make better case fans.
