SilverStone FQ is one of the latest product series added in the company portfolio which was already expanded several times for the past year with various models with dimensions from 80 up to 140mm, made to provide the best possible performance/noise level balance and at the same time deliver very attractive appearance and serious set of additional accessories. The series itself features:
- SilverStone FQ81 – a 80mm x 25mm fan equipped with Fluid dynamic bearing made to operate at 1200 ~ 2800 revolutions per minute range, providing airflow level range of 12 ~ 27.53CFM, static level pressure of 0.45 ~ 2.52mmH2O at noise level of 15 ~ 28.5dBA
- SilverStone FQ91 – a 92mm x 25mm fan equipped with P.C.F. bearing (Powder Copper Fluid Bearing) made to operate at 1000 ~ 2500 revolutions per minute range, providing airflow level range of 19.8~44.2CFM, static level pressure of 0.35~2.2mmH2O at noise level of 14.7 ~ 24.8dBA.
- SilverStone FQ121 – a 120mm x 25mm fan, which I’ve already tested in the past and which is equipped with P.C.F. bearing (Powder Copper Fluid Bearing) made to operate at 1,000 ~ 1,800 revolutions per minute range, providing maximum airflow level of 67.5CFM, static level pressure of 0.54 ~ 1.82mmH2O at noise level of 16.4 ~ 24 dBA.
- SilverStone FQ122 – a 120mm x 25mm fan, which I’ve already tested in the past and which is equipped with P.C.F. bearing (Powder Copper Fluid Bearing) made to operate at 800 ~ 1500 revolutions per minute range, providing maximum airflow level range of 37.8 ~ 63.8CFM, static level pressure of 0.41~1.5mmH2O at noise level of 14.5 ~ 24.9dBA.
- SilverStone FQ141 – a 140mm x 25mm fan equipped with P.C.F. bearing (Powder Copper Fluid Bearing) made to operate at 500 ~ 1000 revolutions per minute range, providing maximum airflow level range of 31.4 ~ 62.0CFM, static level pressure of 0.28 ~ 1.21mmH2O at noise level of 14.7 ~ 20.7dBA.
I’ve already tested the 120mm models part of the FQ series and now I believe it is time to check what the big brother has to offer in terms of cooling performance and additional benefits.
SilverStone FQ141 was delivered to me for performing a test and review in the standard for the FQ series, made of a transparent plastic package with two parts connected to each other. On the front side of the package there are some technical details related with the product, a QR code leading to the official web page and a full view of the fan structure, showing the very aggressive fan design and most of all the beautiful colour scheme.
As usual, the full technical specification describing the product is placed on the back of the package written in several languages. And being part of the FQ series the model is made to provide enviable airflow/static level pressure balance.
So first things first, let’s continue with checking out the fan structure…
SILVERSTONE FQ141 STRUCTURE
And this is what the fan looks like out of its plastic fortress.
SilverStone FQ141 is made of a completely painted in white square P.B.T., which is a very solid and reliable material for the frame with dimensions of 140 x 25mm. Typical for the FQ’s series, is that the frame itself features a very thin border forming a cylinder around the propeller to provide the best possible airflow level and very aggressive appearance. Apart from that, on each corner of the frame there are two spots needed for sticking anti-vibration rubber pads for additional noise reduction.
The frame itself is made to be installed on a 140mm case fan slot or as a main cooling unit for a cooler radiator compatible with 140mm fans. The frame offers four pre-made holes on the four sides for LEDs. Unfortunately, the fan is not supplied with backlight LEDs.
As part of the SilverStone FQ series, FQ141 includes 11 entirely painted in light blue, very sharply angled blades designed according to the air-inlet technology for optimizing the aerodynamic and reducing the noisy air turbulence. With this propeller design it is obvious that this model is entirely made to provide the best possible airflow level and static level pressure.
The connection between the propeller and the frame is made with P.C.F. bearing (Powder Copper Fluid Bearing) offering stable 500 ~ 1000 revolutions per minute with airflow level range of 31.4 ~ 62.0CFM, static level pressure range of 0.28 ~ 1.21mmH2O, noise level range of 14.7 ~ 20.7dBA. With this bearing the fan is expected to provide long life span up to 150,000 hours.
SILVERSTONE FQ141 ADDITIONAL ACCESSORIES
After checking the fan structure I believe it is time to check the additional accessories added in the box and accompanying the product.
The standard SilverStone FQ141 package features:
- a set of 4 metal screws for installing the fan to a case fan slot
- a set of 4 entirely painted in black rubber pins to attach the fan to a case fan slot
- anti-vibration rubber pads for reducing the vibrations of the fan
- speed reduction cable
- molex to 3 pin adapter for powering the fan directly from the power supply
After I spent some time describing the fan, I believe the time has arrived to check how it will perform.
SILVERSTONE FQ141 TESTS
The tests will be conducted in my standard way. I will mount the fan and test it at 5V/7V/9V/12V and my goal will be to check the performance of the fan in real conditions. The product will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the test can in no way be the same if the fan is mounted on a cooler or on the case fan hole of any modern computer case. I will measure the amount of air going through the fan for one hour and its speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.
And this is what the fan looks like when operating on the test stand:
The test results are shown in the following charts:
Airflow through the fan at 5V, 7V, 9V, 12V
Propeller rpm during the tests at 5V, 7V, 9V, 12V.
The anemometer showed the following air speed passing through the propeller:
After mounting the fan onto the stand, and leaving it to run for about 30 minutes at maximum speed, it was time for the tests to begin.
As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and SilverStone FQ141 made at least one full revolution at about 7.5V. To do the first test I had to decrease the operating voltage to 5V.
Test at 5V:
At the first test conducted at 5V, SilverStone FQ141 was rotating with stable 480 revolutions per minute, providing airflow level of 39.36 cubic metres per hour. At this test the fan was completely silent.
Test at 7V:
At the second test conducted at 7V, SilverStone FQ141 reached airflow level up to 59.52 cubic metres per hour while rotating with stable 675 revolutions per minute. At the second test the fan remained absolutely silent.
Test at 9V:
At the third test conducted at 9V, the fan was rotating at 825 revolutions per minute providing airflow level of 75.84 cubic metres per hour. At this test the fan was completely silent again.
Test at 12V:
At the last test conducted at 12V, the fan reached its maximum performance providing airflow level of 95.04 cubic metres per hour while rotating at 1035 revolutions per minute and the model remained silent.
I believe the time to share my conclusions has arrived:
SILVERSTONE FQ141 CONCLUSIONS
SilverStone FQ141 Performance:
SilverStone FQ141 is the biggest and the most quiet model in the series made to provide the best possible airflow level, static level pressure, of course by keeping the noise level very low. The fan itself is a very good choice to boost the overall airflow inside every modern case compatible with 140mm fans. Apart from that the fan can be a good choice as a main cooling unit for CPU heatsinks or AIO radiators installed on low or middle grade processors working at default or a little bit overclocked frequencies. For extreme overclock this fan is not the best option and will have hard time to keep the hardware cool, stable and most of all quiet.
The model itself is equipped with a very reliable 4-pin PWM powered and regulated bearing providing steady revolutions per minute and life span of up to 150 000 hours, which will guarantee a long life and well balanced and reliable performance.
SilverStone FQ141 Appearance:
SilverStone FQ141 is one really eye-catching product featuring the typical for the series light blue/white colour scheme combined with very aggressive propeller appearance. As I’ve already said in the SilverStone FQ121 review, the colour scheme is not really the best choice for modern, entirely painted in black case and colorful hardware but I believe with some imagination and well selected products in the white/blue colour scheme this model can be a part of a really attractive system or modding project.
I think SilverStone FQ141 deserves the following reward:
SilverStone FQ141 has been added to the 140mm fans catalogue.
