To perform this test and review the guys from Fractal Design provided me with Venturi HF-14 and Venturi HP-14 PWM, which arrived inside amazing looking packages with some basic details and big pictures of the fans themselves located on the front panels.
|Venturi HF-14||Venturi HP-14 PWM|
The packages are made as a carton boxes painted entirely in black/light blue colour scheme with a front flap covering a transparent cut, through which the structure of the fans can be seen. Also when the front flap is lifted there are a lot of details regarding the products and the technologies used so these fans can be created.
|Venturi HF-14 features||Venturi HP-14 PWM features|
As always, for every product from every brand, the full technical specifications plus several additional pictures regarding the fans structures are located on the back side of the carton boxes.
I believe it is time to put the packages aside and check the fan structure since definitely both of the fans are pretty interesting products.
Fractal Design Venturi HF-14 and HP-14 PWM STRUCTURE
Before I start checking the fan structure, I would like to mention that actually both of the fans offer identical, pretty innovative and very solid frame structure but entirely different propeller design and most of all totally different performance and purpose.
|Venturi HF-14 front view||Venturi HP-14 PWM front view|
Both of the fans are designed with pretty unique, entirely painted in black matte octagon frames made from high-grade glass fiber reinforced thermoplastic polymer with one pretty interesting feature. Actually both of them have no mounting holes since the vibration-dampening corners, made from solid high-quality synthetic rubber are detachable.
|Venturi HF-14 120mm corners||Venturi HP-14 PWM 140mm corners|
Yes … the mounting holes are located on the corners and in fact, the fans could be installed on a 120mm fan slots by using the smaller corners or can be mounted on a 140mm fan slots by using the bigger corners. Pretty interesting feature, which I really like, since it provides versatile mounting and cooling options. Also, installing the corners is not exactly an easy task, since a lot of pressure is required but after they are attached to the frames, they provide rigid and reliable connection and most of all reduce the vibrations a lot.
Apart from that, on the back of the frames there are 4 aerodynamically shaped thin stator struts, made to reduce the noise and any unwanted turbulence.

Apart from the identical frames both of the products are equipped with entirely different propellers, made to provide different cooling performance and to specify the fans’ purpose.
The black matte propeller of Fractal Design Venturi HF-14 is designed with 11 pretty narrow but very sharply angled blades and geometry optimized for a ground-breaking airflow, perfect for low-restriction usage scenarios such as computer case ventilation and low-density heatsinks or radiators.
On the other hand, Fractal Design Venturi -14 PWM’s black matte propeller, featuring 7 very wide and blades with small angle, is optimized for high pressure, delivering high performance results in high restriction usage scenarios, such as in use with dense heat sinks or water cooling radiators.
In addition, both of the propellers offer strategically placed notches on the back side of the blades, which further reduce and disperse any humming noise produced when the blades pass the stator struts. Also, both of the blades are equipped with the trip wire technology, which introduces a micro-turbulent layer that combats elements that negatively affect performance, resulting in quieter operation.
The connection between the frames and the propellers is done by FDB-bearings equipped with a counter-balanced magnet that reduces the axial tension on the bearings and provides silent operation and very long lifespan of up to 150 000 hours.
The powering and regulation method for Fractal Design Venturi HF-14 is done by a pretty long – 500mm, entirely sleeved in black mesh 3-pin cable and connector, while the Fractal Design Venturi HP-14 PWM is equipped with a PWM control offering a very wide speed range, starting at only 400RPM (400 +/- 100 RPM).
Enough about the fans’ structure… Let’s check the additional accessories provided with the products.
Fractal Design Venturi HF-14 and HP-14 PWM ADDITIONAL ACCESSORIES
Both fans arrived with almost identical accessories pack, with small differences.
|Venturi HF-14 accessories||Venturi HP-14 PWM accessories|
The accessories packs offer:
- One set of 4 black metal installation screws to attach the fans to the case fan slot
- One set of 4 black rubber corners for installing the fan on 120mm fan slots
- One set of 4 black rubber corners for installing the fan on 140mm fan slots
- Low-speed adapter for reducing the speed without the use of a fan controller ( Venturi HF-14 )
- A PWM Y-cable, for connecting additional fans to a single PWM motherboard header or PWM fan controller ( Venturi HP-14 PWM )
I believe it is time to install the two fans on my test stand and check how they will perform.
Fractal Design Venturi HF-14 and HP-14 PWM TESTS
The tests will be conducted in my standard way. I will install the fans and test them at 5V/7V/9V/12V and my goal will be to check the performance of the products in real conditions. They 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 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 fans for one hour and their 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 fans look like installed on my test stand:
The test results are shown in the following charts:
Airflow through the fans 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 propellers:
After mounting the fans onto the stand, and leaving them to rotate 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 Venturi HF-14 made at least one stable revolution per minute at about 4.5V, while Venturi HP-14 PWM started rotating at 8V. To do my tests I had to flatten the operation voltage to 5V for both of the fans and check their performance.
Test at 5V:
The first test, performed at exactly 5V, showed 630 revolutions per minute and airflow level of 70.08 cubic metres per hour for Venturi HF-14, while Venturi HP-14 PWM was not able to provide any stable airflow and revolutions per minute. At this test the first model was completely quiet.
Test at 7V:
At the second test, conducted at 7V, Venturi HF-14 was working at 810 revolutions per minute, delivering airflow level of 90.24 cubic metres per hour, while Venturi HP-14 PWM was rotating at 330 revolutions per minute providing airflow level of 18.72 cubic metres per hour. At this test the first model started generating a tiny noise coming out of the air passing through the propeller, while the second fan remained silent.
Test at 9V:
The third test conducted at 9V, made Venturi HF-14 deliver 108.96 cubic metres per hour at 990 revolutions per minute, while Venturi HP-14 PWM was rotating at 870 revolutions per minute and providing airflow level of 58.56 cubic metres per hour. At this test Venturi HF-14 increased the noise coming out of the air passing through the propeller, while the Venturi HP-14 PWM started generating a tiny noise mixed with a noise from the motor.
Test at 12V:
At the last test performed at 12V, both fans reached their maximum performance, which for Venturi HF-14 was airflow level of 135.36 cubic metres at 1200 revolutions per minute, while for Venturi HP-14 PWM it was 101.28 cubic metres per hour, while rotating at 1485 revolutions per minute. At this test, the first model was pretty noisy, while the second fan was distinctively loud.
Fractal Design Venturi HF-14 and HP-14 PWM CONCLUSIONS
1. Fractal Design Venturi HF-14 and HP-14 PWM Performance:
A very long time ago I had the chance to test and review the first fans part of the Silent R2 series by Fractal Design and now years later I touched the latest arrivals in the company portfolio, which to be honest I really enjoyed, since I saw the huge performance and quality improvement of their cooling products.
Even though both are part of the Venturi series, the HF-14 and HP-14 PWM are two totally different fans made to provide totally different performance behavior in correspondence to their purpose.
Venturi HF-14 is actually the more versatile, in matter of performance, fan in the series since it is made to deliver the best possible airflow/static level pressure/noise level balance, which makes it a very good choice to operate as a case fan to boost the overall airflow inside the case or as a main cooling unit for CPU heatsinks with low density fin structure and compatible with 120 or 140mm fans.
On the other hand, Venturi HP-14 PWM is more likely focused on cooling CPU heat sink or water cooling radiators with high density fin structure since it offers pretty exciting static pressure level and will definitely provide the option to achieve stable CPU operation and overclocking results.
Also, the dampening corners feature is an amazing touch, which will totally provide a lot of options and wide range of cooling capabilities. As a matter of fact, both of the fans can be mounted on a 140mm or 120mm case fan slots or CPU heat sinks and water cooling radiators.
Apart from that, through the tests I noticed that when working at 5V and 7V both of the fans are pretty quiet, while when working at 9V or 12V they become pretty noisy, and for Venturi HP-14 PWM I should say, even loud. Anyway, when they are set to automatic regulation they maintain a good performance/noise level balance.
2. Fractal Design Venturi HF-14 and HP-14 PWM Appearance:
In addition to the pretty good cooling capabilities both of the fans offer different but very interesting structure and unique eye catching appearance. In fact, the only common thing between the two models from the Venturi series is actually the black octagon type frame and the rubber dampening corners.
Both of the fans offer two entirely different painted in black propeller structure, which when combined with the frames will deliver the feeling of a high-tech, stylish and at the same time pretty neutral stance inside every modern case or modding project.
I think Fractal Design Venturi HF-14 deserves the following reward:
