Arctic BioniX F120 gaming fan review

Benchmarks and Conclusion


Testing Methodology

Testing a fan is not as simple as testing a CPU cooler or a graphics card. For testing a particular fan one needs at least 4-5 fans of different kinds to stress test everything in a PC which also depends on the amount of ventilation a case has. So, the best way to test the cooling of a fan is to use them on a heatsink. For this purpose, I tested this fan on a Cooler Master MasterLiquid Radiator and on an air cooler called Thermaltake Contac 12 and compared them with the stock CPU cooler fans.

As for noise testing, I used a total of 5 different fans along with the BioniX F120 fans and tested them at different speeds.

For testing, I used my testing rig which I use for other things as well:-

Intel Core i5 6600K: Check on Amazon

Asus Z170 Pro Gaming: Check on Amazon

2x 4GB DDR4 2400Mhz Corsair Vengeance LPX: Check on Amazon

320GB WD HDD: Check on Amazon

TP-Link N300 Wifi PCI Card: Check on Amazon

Cooler Master MasterWatt Lite 500W: Check on Amazon

Cooler Master 690 III: Check on Amazon

1x 120mm Corsair AF fan: Check on Amazon at the rear, 1x 120mm DeepCool TF120 fan(Used from Radiator): Check on Amazon

I tested the fans at 25C which I measured using a Digital LCD thermometer and kept it in consideration if the room temperature changed anytime while testing. For measuring the CPU temperature and fan speed I used CPUID HWMonitor and for overclocking the CPU I used the Asus AI Suite 3. For tweaking the fans speed I used Bios as well as Asus AI Suite 3. 

For testing the noise I used a Digital noise tester. The how’s of testing will be explained below soon.

Test #1: On Radiator

So, I took the Cooler Master’s ML 240 radiator and installed the two Bionix F120 fans on it and tested the temperature as well as noise. I tested the performance of these fans at different speeds and at different CPU clock speeds and then I compared it with the stock Air pressure Cooler Master fans which are one of the top cooling fans for a radiator.

After installation, I opened up the side panels and the top meshed panel to allow maximum airflow through the radiator.

Heavyload was used for stress testing for 15 minutes for each clock and at different fan speed.

Temperature comparison graph:-

Note: The minimum fan speed CM 120 fans can go is 750RPM from the BIOS and the BioniX fans can go close to 700RPM. Unfortunately, I forgot to test the BioniX fans at 750RPM speed but I think the comparison is still fair enough as there is an only 60RPM difference.

I compared the temperature at their minimum speeds and at their maximum speeds. But making it fair, I tweaked the fan speed of the BioniX fans to match that of the Cooler Master fans maximum speed.

What you can see from the above graph is that the Cooler Master air pressure fans are, of course, better than the BioniX F120 fans but the interesting thing to observe is that as you increase the speed of the BioniX fans to max, they perform better than the Cooler Master fans. Though at low speeds like that of 2000RPM and lower than that Cooler Master fans are the clear winner because air pressure fans are specially made for cooling heatsinks only.

From the graph above, it’s clear that BioniX F120 can be a decent replacement that will perform better at max speed which i.e., 2850RPM which is insanely high.

Noise comparison graph:-

Note: The decibel numbers shown below in graph are of 2-2 fans from each vendor accompanied by the sound of the pump. Noise testing is very difficult when the environment is very noisy but I managed to make the room as quiet as possible. But +-1dbA error can be expected and just as I said that I forgot to test the BioniX fans at 750RPM speed, I measured noise of BioniX F120 at 690RPM. The difference in noise levels will still not be noticeable between 690RPM and 750RPM.

The BioniX F120 fans are exceptionally quiet when compared to the Cooler Master Air pressure fans and at the exact equal speed of 2030RPM, it’s quieter by a big margin of 10dbA. I didn’t expect that much. When they were spinning at 2030RPM, they were not bothering me at all. It felt like that they were spinning somewhere between a silent profile and a standard profile. So, even if the fans are made to spin at the max speed, they are almost equivalent to the Cooler Master fans giving a little better cooling as you saw in the previous graph.

Test #2: On Heatsink

The second test I did was on Heatsink of Thermaltake Contac Silent 12 CPU cooler of which I am soon going to post a full review. I compared the BioniX F120 fan to the stock fan which came with the cooler that is an air pressure fan in terms of temperature and noise. Again, after installation, I opened up all the panels to allow maximum overflow and stress tested the cooler with both the fans separately at different clocks and different fan speeds.

Fortunately, the same clips by which the TT Contac Silent 12’s fan was held on to the heatsink were able to hold the BioniX F120 fan just perfectly.

Just like before, the BioniX F120 is not able to beat the Air pressure fan from Thermaltake. The reason is the same. BioniX fan is air flow fan and the TT fan is an air pressure fan. But just like before making the fan run at full speed gave the stock TT fan good competition in cooling. Although, it’s clearly not the winner here as the TT fan gives the same amount of cooling at almost half the speed of BioniX F120. But it can be a decent replacement here if you just turn up the speed to max.

Noise Graph:-

BioniX F120 fan again won by a big margin when it was run at an equivalent speed of TT Contac Fan which is also the max speed i.e., 1520RPM. At 700RPM, things were similar but BioniX F120 is a damn silent thing.

Test #3: Noise Test comparison

Here I tested the BioniX fan with 5 other fans to see which is noisier. I have separated the graphs for minimum and maximum fans speeds. As the monitoring software was not able to detect the fan speeds of some fans, I had to use the Minimum and Maximum speed graphs. Some of the fans of which I was able to tweak the fan speed, I ran them equal to the speed of BioniX fans and included the decibels in the maximum speed graph. The noise numbers are in dbA

For testing each of these fans I connected them to a 4 pin fan header on my motherboard and kept the fan outside the case depending on how much length its wire has. This makes the interference of PSU fan noise even lesser.

These are the 3rd and 4th noise graphs where you can see the outstanding performance of BioniX F120 fans in silence. Although, I was unfortunate that I didn’t have had any Noctua Fans which are supposedly the quietest fans available in the market but the other fans which I compared are also popular among PC builders.

I made the top 3 bars of different colours excluding the Red one that explains the decibels of each fan at a fixed speed of 2000RPM. You can clearly see the difference, I don’t have to explain. No fan won over the BioniX F12 in quiet operation but in cooling, it was a little behind.

When I completed all these tests, only one thing came to my mind: Damn Silent Operation!

Arctic BioniX F120
9.1 / 10 XG
  • Decent Aesthetics and Design
  • Strong blades with minimum thickness
  • Throws immense amount of air
  • Huge range of speed
  • Damn Super Silent!
  • 10 years of warranty
  • No RGB version
  • Cooling is not exceptional
  • Doesn't comes with a hardcopy of instructions manual
So, I can see that the improvement made by Arctic is working in the silent operation. I wasn't expecting that much silent performance. Although, cooling needs to be improved a little bit because Arctic's new Freezer 33 Esports edition and Freezer 33 TR use exactly these fans but making them run at full speed gives good performance and make them comparable to the static pressure fans. The quality of the fans is what I admired the most and I am thinking of using them in my test rig for intake and exhaust.
