Silverstone FHP141-VF – Test and Review

SilverStone FHP series is a pretty tiny series, which until now was offering just one model – Silverstone FHP141. A fan, which I had the chance to test and review in the past and which was holding the performance record in my 140mm fans catalogue for quite some time. The guys from Silverstone just introduced the next big thing, which is the FHP141-VF designed with a bit better performance and a pretty unique feature, about which I will talk a bit later.

For this test and review I received the new FHP141-VF model, which was provided to me in the typical for the series big and very thick carton box painted grey/black and white with a big picture of the product on the front panel mixed with some technical details and description of the new attachable corners.

On the other hand, the full technical specifications written in several languages and some additional explanations regarding the structure and the features of the fan are placed on the back side of the carton package.

As a big fan of high speed and high performance fans I am really excited about the latest arrival in the SilverStone FHP, which stands for high pressure, series. So let’s waste no more time, put the package aside and check the fan structure and later the performance of the product.

 

Silverstone FHP141-VF STRUCTURE

By opening the package at first sight the fan looks almost identical to its ancestor but this is just an optical illusion.

Silverstone FHP141-VF itself is equipped with an entirely painted in black matte, really thick and solid octagon frame with overall dimensions of 140 x 140 x 25mm and weight of 225g designed to be installed on a 120mm mounting holes with a 105 x 105mm screw hole pattern.

The interesting thing regarding the frame is actually the additional 4 plastic corner brackets, which should be attached to each corner of the frame via small screws and give the owners of the fan the option to install the fan on 140mm case fan slot or CPU cooler compatible with 140mm fans with 125 x 125mm screw hole pattern. Of course, all of the brackets are also entirely in black.

In addition it seems the new model is using the same frame as its ancestor since there is a place in the frame in which a small switch could be installed. The same switch which was used in the previous model to switch between Quiet and Performance modes. In this version the switch is missing and the fan has only one operational mode.

On the other hand, FHP141-VF is designed and equipped with a completely new propeller which features 7 pretty wide and very sharply angled blades forming the entirely black matte propeller, which is designed to provide the best possible airflow/static pressure balance. The interesting thing regarding the propeller is that it is designed in a way that the blades profile is identical when the fan is seen from the front and from the back side. And it is made like this because the fan is designed to provide the option to rotate in both directions and to reverse the airflow.

A feature, which I find just amazing and very, very useful!

To perform its duties FHP141-VF is equipped with dual ball bearing made to last of up to 70 000 hours constant operation, which is capable to operate at 500 ~ 2000 revolutions per minute range, with operational voltage range of 6 – 12 V and rated consumed power range of 0.48 ~ 3.84W.

I believe that you’ve already noticed on the pictures above that this fan also is powered and regulated by a sleeved in black 4-pin PWM cable and connector and there is a second much shorter cable made to provide the option to attach a second fan directly to FHP141-VF without the need of Y-splitter. Very good idea and I can say really useful trick.

On the other hand there is an additional shorter cable with just two wires and connector to which the external switch with PCI slot bracket should be attached. The purpose of the small switch is to reverse the rotation of the propeller and further change the direction of the airflow. The cable is pretty long so the bracket can be installed on the back of the case without any issue but I really can’t understand why the sleeve around the cables is in white if every other detail regarding the fan is in black colour or with metal shine.

Enough about the fan structure, so let’s proceed with checking the provided additional accessories.

 

Silverstone FHP141-VF ADDITIONAL ACCESSORIES

Since this is a product from the SilverStone portfolio it is demanded to provide a high level of quality and compatibility options and for that reason the product is provided with a very extensive accessories pack. And to maintain order, all of the additional accessories were packed in separate nylon bags to ensure that all of them will be in perfect condition accompanying the fan on its delivery.

The standard Silverstone FHP141-VF package features:

  1. a set of 4 metal screws for installing the fan on a case fan slot
  2. a set of 4 rubber pins for installing the fan on a case fan slot
  3. a set of 4 plastic corners so the fan can be installed on a 140mm case fan slot or CPU heat sink
  4. a set of 4 small metal screws to attach the corners to the fan frame
  5. a 3-pin connector inside a 4-pin connector to 4-pin molex connector for powering the fan directly from the power supply
  6. a PCI slot bracket to be installed on the back of the case with the airflow direction switch.

I believe I’ve spent some quality time checking the fan structure and accessories so I guess it is time to check how it will perform.

 

Silverstone FHP141-VF TESTS

The tests will be conducted in my standard way. I will install the fan and test it at 5V/7V/9V/12V and my goal will be to check the performance of the product in real conditions. It will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the tests can in no way be the same if the models are mounted on a cooler or on the case fan slot 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 installed on my test stand:

The test results are shown in the following charts:

Airflow through the fan at 5V, 7V, 9V, 12V

Propellers 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 rotate for about 30 minutes at maximum speed, it was time to do the tests.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and Silverstone FHP141-VF made at least one full revolution at about 7V. To do the first test I had to decrease the operating voltage to 5V.

Test at 5V:

At the first test conducted at exactly 5V, Silverstone FHP141-VF was completely unable to operate.

Test at 7V:

Through the second test conducted at 7V, the fan was providing airflow level of 128.88 cubic metres per hour, while rotating at stable 1350 revolutions per minute and maintain a pretty significant noise profile.

Test at 9V:

The third test conducted at exactly 9V, showed airflow level of 162.24 cubic metres per hour, while rotating at 1725 revolutions per minute. Through the third test the fan was already really noisy, which was totally expected, considering the overall performance.

Test at 12V:

At the last test conducted at 12V sharp, FHP141-VF reached its supreme cooling performance, which was revolutions per minute count of 2115 and airflow level of 212.64 cubic metres per hour. Through the last test the generated noise was just huge. The fan was roaring like a beast.

With the review and the tests performed I believe it is time to express my thoughts regarding the product.

 

Silverstone FHP141-VF CONCLUSIONS

1. Silverstone FHP141-VF Performance:

After I’ve spent a couple of hours having fun with the structure, the features and the overall performance of the fan I find this product really appealing and most of all really promising.

Let’s face the reality… This is a very noisy and at the same time extremely potent fan designed to provide massive airflow and static pressure levels for users, which demand reliability from their highly or even extremely overclocked processors. This product is definitely made to be installed as main cooling unit on massive heat sinks or water-cooling radiators compatible with 140mm fans installed on top notch processors working with full load at overclocked frequencies for extended period of time. The fan will definitely handle to provide the needed airflow.

For the users seeking quiet operation, please look for another choice. This is not a fan for daily usage, while browsing the web or listening to music.

Regarding the noise … there is nothing much to say apart from that with this airflow I wouldn’t expect less in matter of decibels. Through the test at 7V the noise from the fan was bearable but still through the 9V and 12V tests the noise level is really serious and the fan roars like a pure beast. Totally expected!

 

2. Silverstone FHP141-VF Appearance:

In matter of appearance, I should say that FHP141-VF is a fan designed to provide brutal force and at the same time to stay totally neutral installed in a case with black/grey colour scheme or mounted on a CPU cooler and water-cooling radiators.

I think that Silverstone FHP141-VF deserves the following reward:

Silverstone FHP141-VF has been added to the 140mm fans catalogue.

Official price (MSRP): Silverstone FHP141-VF  –  20 euro

Warranty: 24 months

 

Special thanks to SilverStone for providing us with a test sample.

    BTW, thank you for doing this. I’m trying to pick a new fan, and the manufacturer ratings are misleading. Like, I was going to buy this Silverstone because the manufacturer said it moves 290 m^3/h, but you showed it moves only a little more than 2/3 of that.

      Hello Phil,

      I don’t know for what you are going to use this fan but keep in mind that both this and the previous models are not really made for normal daily usage while browsing, listen to music or watch movies on your pc.
      These fans are extreme powerful and very loud. The second one is also really innovative with the reverse function.
      Personally I believe this fan is focused for extreme enthusiasts while making OC records
      Regarding the different results, indeed the difference is big but still there are many variables which might cause this. And I doubt that SilverStone is missleading anybody.

    Since you do all these fan reviews, you should really spend $30 on a decibel meter and report their noise levels.

      Hello Phil,
      To perform real and accurate Noise tests I will have to obtain much more prices Noisemeter than one which costs 30 dollars 🙂 Also to provide accurate results I will need to make a special noise isolated room. Something which is not really easy and most of all cheap thing to do.

      Believe me I thought many times about this in the past.

    Is “Noise Level 4” in your scoring louder than “Noise Level 6”?

    • Reply Dobrin Krastev 28.09.2017 at 9:59

      Hello Phil,

      Yes, the lower the score is, the louder the fan is. Score 10 is deadly quiet, while score 1 is close to jet engine. 🙂

      Best Regards

    How does the noise compare to that of the original FHP141?

    • Reply Dobrin Krastev 28.09.2017 at 9:59

      If I remember correctly the first model was much more louder than the second version.

    I think it’s for dust management. It’s a “feature” on a few other fans; they’ll reverse at the start to push off dust on the blades that settled. Maybe it does the same here.

    • Reply Dk_vr 09.05.2017 at 9:56

      Hello,

      If I remember right, there were VGAs which were using this technology for dust cleaning.

      Anyway this model is not designed for dust cleaning because by pressing the button, the fan stops rotating in one direction and then starts rotation in the other direction.

      Best Regards,

    So.. I am interested and can’t think of anything worth mentioning.. what for do you think one would reverse the direction of the flow? (interesting feature, but in what cases one may wish to use it)
