If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. Fewer reactions to the “rumble” of the CO variant could perhaps stem from the fact that it is probably a less widely used fan, owned by fewer people, so there will be less feedback/less negative criticism of the acoustic properties? I will soon find out how close they are to the actual performance data once I finish all tests on the Longwin apparatus. The P12 PWM PST is able to switch into silent passive mode when PWM signal is below 5 % due to its new motor.

These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. In addition, we will select fans that will have the highest airflow in the 31 dBA mode and there will be room for further noise reduction. Note: Specifications chart, which used to be in the following place, is now on the second page of the article. Modifying” a cooler by replacing the fan with a relatively more efficient model may not always lead to the desired result.If the BioniX P120 catches up to the P12 anywhere, it’s when the P12’s sharper tonal peaks significantly limit the P12 when the speed is controlled for equal noise level. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . As far as the difference in noise between the variant with fluid and ball bearings is concerned, there can be some, of course, but only at the level of the bearings. This means that at equal noise levels, you will achieve lower cooling performance, and it doesn’t really matter what fan you use.

Normally I would find the silver screws unattractive, but, this particular fan is white, so it should be fine.Also at this level (due to lower friction and less turbulence), there is an increase in efficiency compared to traditional fans that do not have such significantly curved blades. The P12 has larger blades compared to the BioniX P120, although it doesn’t seem like it unless one sees those fans side by side.

This not only guarantees smooth operation, but also ensures that the volume does not increase over time. I don’t remember other peaking frequencies, but 1 kHz and the following harmonic peaks each full kHz are a case of USB interface noise. Whatever the reason, you may have guessed by now that today we are going to be taking a look at an Arctic fan today. Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable). In this review, I will evaluate one of the most popular fans, usually used for chassis cooling, the Arctic P12 PWM PST.The shorter blades of the BioniX P120 A-ARGB are probably due to the implementation of the circular lightguide, which narrows the overall cross-section a bit, which the BioniX P120/P12 rotor would not fit into.

It occurred to me that it might be different, a more rigid material structure with lower thermal expansion. The P12 PWM PST fan (hereafter referred to as the P12, but we’re still talking about the PWM PST variant) has a 5-blade axial rotor, which is typical of Arctic’s current “P” series models.This is also visible in the spectrograph, where in the frequency band of these components the noise is extremely low. I suppose this is the reason Arctic pushed the lighting more with the BioniX P120 A-RGB at the expense of a slightly smaller cross section with a slightly smaller rotor. Starting out, it’s still worth noting that the Arctic P12 compares with the previously tested BioniX P120 A-RGB, although it has seemingly the same rotor – it doesn’t. In non-restrictive environments at low speeds, DeepCool, which has the advantage of a larger outer cross-section of the rotor or rather larger blades, plays a more equal game.
