****Corsair SP120, AF120 and AF140 fan review.****

So I have a selection of Corsairs latest Air Series fans kindly supplied by OverclockersUK and Corsair to test, these come in two types,

• AF = Air Flow are designed to deliver extraordinary air flow whilst remaining quiet.
• SP = Static Pressure are designed to force air flow through compact gaps as found on radiators and heatsinks.

The models I have for testing are,

AF120 Quiet Edition twin pack.
AF120 Performance Edition twin pack.
SP120 Quiet Edition twin pack.
SP120 Performance Edition twin pack.
AF140 Quiet Edition single pack.

The twin packs offer great value for money over a single fan pack, people are more likely to be buying more than a single fan.

The quiet editions differ from the performance editions by just the RPM they spin at any given Voltage.

The fans feature a hydraulic bearing system so they remain quiet and reliable, rubber corners to reduce vibrations and an exchangeable trim ring.

The below video I made shows just how easy it is to swap the trim ring on these fans to best suit your case/build colour scheme.



AF120 Quiet Edition.

The two extra trim rings per fan,

Four Black screws and a 12v-7V step down reducer per fan.

Two leaflets, one about other Corsair items and the other is to tell you to deal with Corsair directly should you have any problems.

The fan.

Below you can clearly see the soft rubber corners for reducing vibrations.

The contents and indeed the fan are identical to the Quiet edition above.


SP120 Performance edition.

Again there are four Black screws and a 12v-7v reducer per fan.

The same two leaflets talking about Corsair products and to use Corsair support directly.

The fan.

The only noticeable difference of the SP series compared to the AF series is the fan blade amount and design

Still the same soft rubber corners.

SP120 Quiet edition.

Corsair specifications - http://www.corsair.com/en/cpu-cooli...high-static-pressure-120mm-fan-twin-pack.html

Exterior.

The contents and the fan are again identical to the Performance edition above.


AF140 Quiet edition.

The contents are again the same, just the fan is that bit bigger than the AF120's.

Testing.

For testing I have used the 120 mm twin packs to cool my Antec Kuhler 920 in push/pull and compared them to the stock Antec fans supplied and BitFenix Spectre PRO 120mm LED fans.

Test bed,
I5 [email protected]
Z77X-UP5 TH
Kingston HyperX 2400MHz (4x4GB)
Intel 520 series SSD
Gigabyte GTX670 Windforce 3X

I used a Hilka Thermometer & Hygrometer to measure the ambient air temperature.

Realtemp was used to record the temperatures of the four cores (then added up and divided by 4)

Prime95 was ran for 30 minutes then the results noted.


Temperature testing.

Noise testing.

I have made a video of each fan below.

I set up each fan and ran them at 12v and 7v where possible, the camera was kept at the same distance from each fan and the settings for this were left alone. A passive PSU was used and jump started via the Green+Black cable on the 24pin with the fans connected to a 4pin molex via an 3pin adapter, there was no other equipment turned on during the filming.

I also downloaded an app for my phone to measure decibels, now I have no way of actually calibrating this correctly, all I can do was set it to 20db late at night in my bedroom with no noise that I could hear, if it remains at this setting then it must be consistent for measuring the fans if kept at the same distance (but please just use your ears and watch the video).


As you can hopefully hear, the Quiet edition Corsair fans are indeed nice and silent at 12v, the Performance edition fans are louder but nothing like the Antec stock fan which is positively offensive to ears when at 12v.

The BitFenix Spectre PRO fans are also quiet, but just that bit louder than the Quiet editions when both are at 12v.


Conclusion.


I was very impressed with the Corsair AF and SP series fans, they move a decent amount of air at both 12v and 7v, the SP series perform extremely well as they should when tested on a closed loop water cooler radiator, the fan design obviously does benefit them when compared to the AF series in this scenario.

The BitFenix Spectre PRO 120mm while certainly quiet at 12v was also a worse performer than all the AF+SP series in all but one test (Quiet edition @7v) when testing the Spectre PRO at 7v the core temps were dire and it was making me seriously worried about the CPU safety, it's almost like theres such little airflow that the liquid temperature of the Kuhler and thus the CPU core temp just slowly climb up and up and can not be kept in check.

I like the trim ring option so you can match them to your systems style.

The rubber corners certainly are effective and a nice touch.

They are sturdy and don't "flex" when you try and twist them by holding them at their corners.

Overall, highly recommended, if you have a heatsink or water cooling radiator the SP series work extremely well and for extra/replacement case intake/outlet fans the AF series perform well.

A big thank you to OcUK and Corsair for the opportunity to test these fans.

Stulid, great review as always. I am wanting some sp120's for my h50. As they are now stulid approved I will not hesitate.

It seems that with these fans you don't sacrifice performance for silence as other fans as said to do.

if you don't want to keep the sp120's I'll have them. Hehe. :)

Thanks stulid

Spectre Pro are case fans I believe. Interesting to see the AF120 quiet still perform OK for CPU cooling.

Any chance of getting your hands on the new Noctua fans? :) They're suppose to be very good too.

Stupid, great review as always. I am wanting some sp120's for my h50. As they are now stupid approved I will not hesitate.

Typo of the week! Come on, it's not like he's new on the forums.

I would like to ask a question regarding the PWM pins.

My SP120's are on my Antec 920, and obviously they are 3pin.
My stock antec fan was a 4pin PWM fan.

I can't seem to ramp down my SP120's from the max 1500RPM.
Is there something I can buy that will allow me to reduce the speed of the SP120's?
Such as a 4pin to 3 pin adapter?

You would need some sort of proper fan controller that can alter the voltage given to the fans from the normal 12v, or use the included step down adapter cable.

As an example - http://www.overclockers.co.uk/showproduct.php?prodid=OA-000-ZA&groupid=701&catid=2331&subcat=189

hehe I face-palmed myself after re-looking where I posted.
As I had already asked the same question.

Thing is a fan controller, is the same principle - I even called OCUK, and a rep told me that a fan controller, won't be able to fluctuate the fans speed as it isn't a 4pin fan.
I want the fan to adjust with CPU temps, rather than me manually changing it.

Just like the antec - on idle it was at 600-800RPM, then on load it would go to 2500RPM

The less voltage you give the fan the slower it will spin, Asus have Fan xpert+ ( or 2) software that I think might work with your board.

A quick google came up with this about Asus boards - http://forums.anandtech.com/showthread.php?t=2239501 - http://www.overclock.net/t/1235016/asus-fanxpert-2-on-z77-motherboards/10#post_17023751

Of course the lower voltage you give it, the slower it will run, but what if I want it to adjust automatically depending on load and thus voltage?

As for AI Suite II - that useless piece of software caused so many problems for me last time, that I refuse to install it from now on.
More so, I remember using it, and it couldn't control the fans.
Again, the SP120's aren't case fans, but a CPU/Rad fans.

Fan Xpert II works brilliantly imo. Sod the rest of AI suite though :p
Just install AI suite and get the latest Fan Xpert. You only need to install the elements you want (I only have FXII and Probe installed for example).

Anyway, whichever staff member told you that you need to use 4pin fans on a fan controller is talking balls.
Use any type you want. I do with a Lamptron FC6 which only has 3pin connectors.

Try Fan Xpert II again. If my bottom of the range Asus Z77V-LX can control 3pin fans...
