Silverstone Air Penetrator AP141.
Corresponding specs for the Silverstone are: 1500 rpmp12V / 1000 rpmp7V / 700 rpmp5V 28.26 CFM (5V) / 41.09 CFM (7V) / 64.34 CFM (12V)
18 dBA (5V) / 20.9 dBA (7V) / 30.1 dBA (12V)
Rated 1500rpm, 64.34cfm, 30.1dbA
Rated 12VDC, 0.22A, 2.64W, Fluid Dynamic Bearing

This unit comes with a one year warranty

My Fractal Design Define R4 case has a 3 fan controller for 5. 7 and 12Volt

The 31.5 dB(A) and 41.3 dB(A) respectively for “Accoustical noise” nominal specification declared by the manufacturer for each of the above Noctua units refers to which voltage? How do I read that spec?

I am interested in knowing the noise level for all 3 levels. Also does anyone know if the speed of the fans has dial for gradual increase or they are set just for high 2000 or low 500 only for the 2000 rpm?

And 3000 high and 800 low rpm can be set to run say e.g. at 1900 rpm?
- The 2 Noctua NF-A14 Industrial PPC 3000RPM PWM 140mm High Performance Fan come with 4 pin molex Connector and a "3 phase motor". Is this 3 phase same as the washers and drying machines? Does it mean it is no good to use in my Fractal R4 case?
- Silverstone Air Penetrator AP141 comes with 3 pin M/B connector

My Fractal case has the default 2 fans that come pre-istalled by them. Their Web link for it is: http://www.fractal-design.com/home/product/cases/define-series/define-r4-black-pearl-window

Three-speed fan controller is strategically integrated in the front panel and supports up to 3 fans(does not specify the type of connector though)
Two Silent Series R2 fans included, featuring hydraulic bearings contributing to a longer life expectancy – Silent Series R2 retail fans will now come standard in all cases

My system components are:
Intel 4670K (currently not overclocked), Asus Z87 Sabertooth, 16(2x8) GB DDR3 by Kingston, Intel's Own CPU Cooler, no discrete graphics card added, inside trays populated with 2 Intel SSDs plus 6 Sata HDDs. Corsair AX 750 Gold PSU, running Windows 7 Home 64-bit
Speccy temperature reads are 45C for the CPU. 38C for the motherboard and 30C for storage.
I would like to decrease those temps by 5, 3 and 2 C degrees minimum

Which compatible (with reference to type of connector in case) 3rd fan am I to buy to obtain my goal? I am looking for a compromise between noise level and efficient air cooling. 50db when running at 3000rpm would be acceptable and 40db when running at 2000rpm would be acceptable. And if i can get a decent volume of moving air for at 2000rpm I would not consider the 3000rpm version. I have to ask for advice cause from the specs I cant get my ideal line of a.low noise b.great volume of air and c. moderate rpm.

I would appreciate your ideas, opinions and suggestions

Thank you.

Is there a reason that you want to lower the temps? They certainly aren't high. If was looking to spend money on cooling in your rig, i'd probably get a CPU cooler like a CM Hyper 212 Plus or EVO
CPU Cooler: Cooler Master Hyper 212 Plus 76.8 CFM Sleeve Bearing CPU Cooler ($19.99 @ Newegg)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($29.98 @ OutletPC)

Update: To answer your questions though...
PWM fans can be speed controlled by software (in you case Thermal Radar 2). They will have a 4 pin plug.
Non-PWM fans need to be controlled through hardware voltage controls, such as a fan controller.

Other than that, you seem to have all the information you need.
I wouldn't get the...

I wouldn't get the Silverstone as at only 1.5 dBa louder, the NF-A14 pushes more air.
I would probably go for the NF-A14 PWM model as this will give you finer control over the sound vs airflow. At 2000 RPM, the PWM model would perform very similar to the not PWM model.

As I said, I don't see the purpose in adding any of these fans, as your temps are in no way even close to dangerous. A CPU cooler would at lease give you the option to overclock and would lower CPU temps.

Thank you very much for your comments.Do you think i could achieve lowering temps by 5, 3 and 2 C on the mentioned 3 components with anyone of those fans?

It's possible that it will. There are a lot of factors, such as where you mount your fans, cable management and outside air temps so i'm not confident to give a definite yes or no. Also stock CPU coolers just aren't that good.

For what I would assume will give you best results, I would put the storage in the top cage, and rotate it 90 degrees so it faces front-back. Remove all the drive holders that you don't need and mount 1 intake fan on the top front mount. Mount a second intake fan on the side panel (you will lose some sound deadening). Leave the exhaust fan in the top back position. Make sure your PSU fan faces down, so it draws air from beneath the case and exhausts out the back. This way you should get one fan blowing directly on the storage, and one blowing directly on the motherboard.

Is there a reason you need to lower temps by 5, 3 and 2? Are you trying to grow a tree inside the case or something?

says me now:
Speccy temperature reads are 45C for the CPU. 38C for the motherboard and 30C for storage. as I said before. I have little idea of what should be the "ideal temperatures for those 3 devices" but in my logical sense "the cooler the better" and the 45C and 38C for CPU and Motherboard make me uncomfortable. As i know that heat is the worst enemy of electronic devices and i devised the components I chose to have a cool (in terms of temps) yet powerful machine for my purposes and for longevity as i am -in my late 60's probably- in my last build that i will be able to afford to put together, I tried to future-proof my unit in terms of quality and the longest possible warranty for my components.

Ok. The 4670K CPU can go up to 105C before it shuts down to prevent damage, the motherboard can go to at least 90C, but i'm not 100% sure on it's exact max temp, and the HDD's somewhere around 60C. The SSD's i'm not sure of their max temps, but it's certainly much higher than 30C.

Heat is the enemy of components, but in the case of you computer, your temperatures are nothing to worry about. That being said, If you'd like to add another fan, and it will give you greater peace of mind, it's not going to hurt.

If you want to buy a fan, of the options you provided, I would get the Noctua NF A14 PWM 3000RPM. This way you can control the speed through Thermal Radar 2.
