Cryorig QF120 Performance and QF120 Silent – Test and Review

Cryorig QF120 is a 120mm fan series made to deliver 3 different models, designed with a high-tech structure to provide an ultra wide revolutions per minute range and great airflow capabilities. The models are rated as:

  1. QF120 Silent – made to work at 200 ~ 1000±10 % revolutions per minute range, providing maximum airflow level of 44 CFM, static pressure level of 0.79 mmH2O at noise level range of 5 ~ 19 dBA.
  2. QF120 Balance – made to work at 330 ~ 1600±10 % revolutions per minute range, providing maximum airflow level of 49 CFM, static pressure level of 1.65 mmH2O at noise level range of 10 ~ 25 dBA.
  3. QF120 Performance – made to work at 600 ~ 2200±10 % revolutions per minute range, providing maximum airflow level of 83 CFM, static pressure level of 3.33 mmH2O at noise level range of 13 ~ 37 dBA.

For this test and review I received Cryorig QF120 Performance and QF120 Silent versions, which arrived to me placed inside an identical for both of the fans package made of two very solid carton parts. The first part is actually a carton bed holding the fans in the middle and just below them all of the additional accessories, which are carefully packed in nylon bags and secured in a separate compartment. The carton bed itself is inside a second pretty tight and very rigid carton shell.

Of course, on the front side of the carton shells there are basic descriptions regarding the models, their operational speed and some details regarding the technologies used so these fans can be created. In addition, as a background, there are big pictures of the fans.

Typically the full technical specifications and additional pictures describing the fan dimensions can be found on the back sides of the carton shells. Also, there are smaller pictures describing the additional accessories included in the packages.

I believe the time to check the fan structure has arrived…

 

Cryorig QF120 Performance and QF120 Silent STRUCTURE

Before I start checking the fan structure I would like to mention that QF120 Performance and QF120 Silent offer absolutely identical, very stylish-looking structure made of a very solid plastic frame and propeller. And the only difference between them are actually the performance capabilities.

Both of the fans are designed with identical 120 x 25 mm square, entirely painted in black frame featuring the company’s proprietary Quad Air Inlet™ system, which offers four strategically placed aerodynamic air inlets on each side of the frames. The additional air intake allows the QF Series fans to have a higher air output volume for their diameters, which will result in overall better temperatures for the CPU heatsink or watercooling radiator and higher airflow inside every modern case. The fans are made to be installed on every case fan slot or on a CPU cooler compatible with a 120mm fans.

Additionally, on each corner of the frames there are rubberized vibration dampers to completely kill the fan vibrations, if there are any at all. The vibration absorbers are already built directly into the frames, which is entirely made to make the customer’s life easier.

Since both of the fans feature absolutely identical structure they are equipped with entirely painted in white and very solid looking propellers featuring 11 narrow, but with very sharply angled blades entirely made to provide the best possible airflow and static pressure levels. Apart from that, both of the propellers are designed for optimizing the aerodynamic and reducing the noisy air turbulence.

The connection between the frames and the propellers is done by a 4-pin PWM powered and regulated CRYORIG’s HPLN™ (High Precision Low Noise) bearing, which provides a stable and precisе rotation eliminating excess vibration and noise. The motors of the fans also deliver ultra wide range of RPM settings, which allows to fine tune the fan speed directly through the BIOS settings of the motherboard.

And the thing which I liked the most is that actually on the back of the stator there are stickers stating the operations speed of both of the fans.

 

Cryorig QF120 Performance and QF120 Silent ADDITIONAL ACCESSORIES

Both fans arrived with absolutely identical packages in terms of dimensions and of course absolutely identical accessories pack. So let’s put the fans aside and check the additional accessories added in the boxes.

The accessories packs offer:

  1. One set of 4 rubber pins to attach the fans to the case fan slots
  2. One set of 4 metal installation screws to attach the fans to the case fan slot
  3. One molex adapter for powering the fans directly from the power supply
  4. Product registration card

I believe it is time to install the two fans on my test stand and check how they will perform.

 

Cryorig QF120 Performance and QF120 Silent 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:

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 both of the fans made at least one stable revolution per minute at about 7.5V. To do my tests I had to decrease the operation voltage to 5V and check their performance.

Test at 5V:

At the first test, which was conducted at exactly 5V, below the fans’ starting voltage, QF120 Performance was rotating at 855 revolutions per minute, providing airflow level of 80.64 cubic metres per hour, while QF120 Silent was rotating at only 300 revolutions per minute with airflow level of 21.12 cubic metres per hour. Both fans were completely silent.

Test at 7V:

At the second test, performed at 7V, they showed some pretty serious performance boost. QF120 Performance was rotating at 1305 revolutions per minute, providing airflow level of 125.28 cubic metres per hour, while QF120 Silent was rotating at 540 revolutions per minute with airflow level of 41.28 cubic metres per hour. 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:

At the third test conducted at 9V, QF120 Performance was delivering airflow level of 162.24 cubic metres per hour at 1695 revolutions per minute, while for the QF120 Silent it was 62.88 cubic metres per hour, while rotating at 720 revolutions per minute. At the third test, the first model was pretty noisy, while the second fan remained silent.

Test at 12V:

At the last test conducted at 12V, both fans reached their maximum performance, which for QF120 Performance was airflow level of 201.6 cubic metres at 2100 revolutions per minute, while for QF120 Silent it was 85.92 cubic metres per hour, while rotating at 1020 revolutions per minute. At this test, the first model was extremely loud, while the second one was still dead quiet.

 

Cryorig QF120 Performance and QF120 Silent CONCLUSIONS

1. Cryorig QF120 Performance and QF120 Silent Performance:

After I spent some time having fun and later testing the most quiet and the best performing models from the QF series, I should say I am pretty impressed with the overall performance and appearance of the products.

Even as part of the same same series and offering identical structure both of the fans are made to operate in totally different ways and each with a specific purpose.

Cryorig QF120 Performance is definitely the beast in the series, I should say. The fan itself is designed as a combination of the company’s proprietary Quad Air Inlet system and a very versatile motor working at very wide revolutions per minute range, which will result in amazing airflow level combined with huge static pressure level to keep every processor working cool and stable at default or overclocked frequencies. Of course, to provide the best possible airflow the fan should operate at maximum speed, which makes it extremely loud. But who really cares about the noise level if in fact the CPU of the system is working with 30-40% higher than the stock frequency. For me QF120 Performance is the best choice when chasing high CPU overclocking results installed on a big CPU heatsink or water cooling radiator compatible with 120mm fans.

On the flip side, Cryorig QF120 Silent is the typical fan specifically designed to be installed as a case fan and case fan only, to boost the overall airflow inside every case compatible with 120mm fans. The purpose of this product is to deliver the best possible cooling performance, to be absolutely quiet and keep all of the hardware inside the case running stable, cool and quiet. And I can say that it will perform its duties without any doubts.

Overall both of the fans are very good options for their roles. If someone needs performance and/or chasing overclocking results, QF120 Performance is the fan, while for customers seeking for peaceful and quiet PC operation Cryorig QF120 Silent is their choice.

2. Cryorig QF120 Performance and QF120 Silent Appearance:

In addition to the pretty good cooling performance, both of the fans offer very stylish and at the same time very aggressive looking appearance. Cryorig QF120 fans are really eye-catching products featuring a black/white colour scheme, which will definitely be a great addition to cases or modding projects in black.

I think Cryorig QF120 Performance deserves the following reward:

Best-performance

while for QF120 Silent the best option is:

Most-Silent

    Hi there, start using some measurement for the noise because I bought 2 models because you say its completely silent and they are not event close to silent they are noisy! I can hear them from 2-3 meters clearly on closed PC build! XK-2 for example!

      Hello Stefan,

      Thank you for the suggestion. Actually it is a pretty interesting topic, which will be very nice to be discussed.

      According to http://www.industrialnoisecontrol.com/ the normal noise level for:

      Conversation in restaurant, office, background music, Air conditioning unit at 100 feet. is 60 dBA
      Quiet suburb, conversation at home. Large electrical transformers at 100 feet is 50 dBA
      Library, bird calls (44 dB); lowest limit of urban ambient sound is 40 dBA
      Quiet rural area is 30 dBA
      Whisper, rustling leaves is 20 dBA.

      As you probably know hearing is actually pretty subjective sense and is individual for every person.

      According to NoiseBlocker, BlackSilentFan XK-2 is made to deliver only 19dBA. A noise level, which you are able to hear from 2-3 metres and for me it is quiet.

      In addition:

      Since I made the web page and started testing fans I was thinking hundreds of times how to provide an absolutely quiet sound proof room so I can perform these tests, because it will be totally useless trying to measure fan rated as 19 dBA in a room with ambient noise level of 40 dBA.

      Also I am curious what fan is silent/quiet for you. Could you please tell me brand and model which is absolutely quiet?

      Best Regards

      P.s. Do you mind if I transfer our comments to the http://www.dvtests.com/noiseblocker-blacksilentpro-xk-1-and-xk-2-review/ article?

        Get any reviewed fan from coolingtechnique.com. They put a table for every fan they test with on every volt 5-6-7-8-9-10-12 with measurements of DB, pressure, air flow.. I tested 5-6 of the fans they got tested and their measurement is pretty accurate to me. By their scale 10-11 decibels is silent for me, so just fine any of their reviews and see the rpm/volts which corenspondent to 10-11db. 12+ db would be too much for me for 24/7. In the daytime when there are a lot of noises i can bee good around 13-15db i guess but at night time when i’m reading something on the PC or reading a book in 2-3 meters from the PC anything over 11 is not ok. And its not just me, I spoke abot that with others too.

        The other positive to have a measurements for db is that this is the only way you can really compare two fans. What I usually do is to check both fans on the same DB which got more pressure or airflow, this is the only way I can think of to really compare two fans. With the same noise who can do a better job.
