Silverstone FHP141 Test and Review

In the last few months I tested many products included in the SilverStone portfolio such as fans and cases and all I can say is that every one of them is made at least with one unique feature and with its own purpose. All of the models together cover all possible needs of any regular ot enthustiastic customer.

So let’s check what is FHP141 and how it performs.

Silverstone FHP141 was provided to me for tests and review in a big and very thick carton box painted in a colour scheme featuring grey/black colours with big pictures on the front panel mixed with some technical details and of course the full technical specification in several languages is on the back side of the box. The most interesting thing is that there is no English version of the technical details. Strange..

After I took a quick look at the box and noticed the actual technical details, which are really impressive, I was eager to take the fan out of the package and check if it can really offer such a performance.

And this is what the fan looks like:

Ok… I took the fan out of the carton box and I was pretty amazed. On the first look there were exactly 3 interesting features which I will describe in this article. FHP141 is actually a model meant to provide serious airflow by sacrificing the noise made to cool with brute force offering huge airflow and static pressure.

The fan is made of a not really standard square frame with dimensions of 140 x 140 x 38mm and weight of 220 grams painted in black and a propeller with 7 very wide in surface, painted in black blades with average angle made to provide huge and steady airflow and static pressure. The connection between both of the major components is done by 2 ball bearings for longer life span up to 150,000 hours. Very impressive indeed…  Apart from that the fan can be installed on a standard 120mm case fan slot or CPU cooler.

And here is the first interesting thing and that is the small switch on one of the sides of the frame made to provide two operational modes.

Actually the fan can work in Quiet mode by operating in 500~1200 revolutions per minute range and Performance mode working at 500~2000 revolutions per minute range. Of course, when the fan is working at the full revolutions per minute range it gets a bit noisy.

Maybe you already noticed on the pictures above but there is one more feature that made me look with curiousity and that is the powering and regulation method. The fan is powered and regulated in 6.5V~13.8V DC voltage range by sleeved in black 4-pin PWM cable and connector but there is a second much shorter cable made to provide the option to attach a second fan directly to FHP141 without the need of Y-splitter. Very good idea and I can say really useful trick. The only thing that actually bothers me is that this model is 7.8W and if a second is attached directly to one motherboard connector this could be risky. It is not 100% sure how much power a motherboard connector can handle but still I think it was good to mention it.

After I enjoyed the features of this model I decided to check the additional accessories provided with the fan and they are:

1. 4 rubber dumpers for installing the fan on a 120mm case fan slot
2. 4 metal screws for installing the fan on a 120mm case fan slot
3. a 3-pin connector inside a 4-pin connector to 4-pin molex connector for powering the fan directly from the power supply

I was really eager to check how the model performs:

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 installed on my 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:

As always, 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. For this model I’ve decided to switch to Performance mode and check the full capabilities of the product.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and the SilverStone FHP141 made one full revolution at 4.5V, which is strange since it is rated as  6.5V~13.8V DC voltage range. To conduct the first test I had to increase the voltage to 5V.

Test at 5V:

At the first test conducted at 5V the fan was rotating steadily at 945 revolutions per minute, which is really impressive, providing airflow level of 90.72 cubic metres per hour and that was the only test for this model in which it was silent.

Test at 7V:

At the second test things got even better and the fan reached maximum airflow level of 124.32 cubic metres per hour at 1290 revolutions per minute. At this test there was a tiny noise of the air passing through the propeller.

Test at 9V:

The third test was conducted at 9V and at this operational voltage the model was rotating at 1665 revolutions per minute, providing serious airflow level of 160.8 cubic metres per hour and there was a serious noise coming both from the air passing through the propeller and from the motor of the fan.

Test at 12V:

The last test done at 12V revealed the full capabilities of the product with airflow level of 200.4 cubic metres per hour working at 2025 revolutions per minute. And of course the model became a bit noisier than the test at 9V.

After I was done testing I realised that actually this is the most powerful 140mm which I’ve tested so far. I am impressed by its performance and for sure I will keep this product and use it to do the job and that is to cool where and when needed.

1. Performance: The test results published above say everything. This is a really powerful fan made to provide the performance needed when it is mounted on a heatsink working at Performance mode cooling overclocked or extremely overclocked processors. It will do the job for sure. Of course, this model can be used to boost the airflow level inside every case too by switching to Quiet mode and install it as a case fan at any 120mm fan slot.
2. Noise level: I can’t really say that when operating at Performance mode this fan is quiet but still it is made to provide huge airflow by sacrificing the noise level, while when operating at Quiet mode it is silent and a very reliable product.
3. Apperance:  The fan is painted entirely in black which makes it stay neutral when mounted on a CPU cooler or at case fan slot which makes it a good choice when building a rig according to a specific colour scheme or a modding project.

I think SilverStone FHP141 deserves the following reward:
