The fan carrying one of the most popular brands in the field has been tested against the latest competitors. Among them are the new Arctic P14 Pro (A-RGB), Noctua NF-A14x25 G2 PWM and Thermaltake Toughfan 14 Pro. And many others (including the FD Momentum 14/RGB) with which the TL-B14 will cross paths. In any case, the geometry of the Thermalright impeller is efficient, the price is low, and the results are impressive.
… and of airflow
With airflow measurements, we can well explain why the test tunnel is shaped the way it is. It doesn’t consist of two parts just so that the “exhaust” can be conveniently clogged for pressure measurements. The anemometer (i.e. the wind speed measuring instrument) is held together by two parts, two formations, through the flanges.
The front part, at the beginning of which the fan is mounted, becomes steadily narrower and from about two thirds of the way through the cross-section is smaller than that of a 120 mm fan. The reason for this is that the cross-section of the anemometer is always smaller than that of the fans tested. The taper towards the anemometer fan is as smooth as could be chosen and the tunnel walls are smooth. This has minimized the occurrence of unnatural turbulence.
The difference between the cross section at the intake (fan under test) and at the constriction point (anemometer) also means a difference in dynamic pressure, the principles of the Venturi effect apply here. In order to avoid distortion at this level and to ensure that the fan airflow is not different from what it actually is, the Bernoulli equation must be applied to the measured values (for maximum accuracy, the calculation also takes into account the internal cross-sectional area of the anemometer, i.e. its inactive part ). After all this, it is again possible to confront our results with the paper parameters.
We use an Extech AN300 anemometer with a large 100 mm fan for the measurements. Its big advantage over other anemometers is that it is made for bidirectional sensing. This allows tests at different fan orientations. However, the “pull” position is more suitable or accurate for measurements, even though it may not seem so at first glance, but we’ll explain.
Here, we get to the second part of the tunnel, the part behind the anemometer. It is part of the whole device, mainly to allow a laminar flow of air to arrive at the impeller of the anemometer. Otherwise, uncontrolled side whirls would be reflected in the results, which are inconsistent with accurate measurements. Therefore, we will test the flow in the pull position. If anyone would like us to elaborate more on this topic, we can elaborate further at any time in the discussion below the article. Ask away. 🙂
In regard to the anemometer, we shall return for a bit to noise measurements and to setting modes according to fixed noise levels. It may have occurred to you as you were reading that the anemometer fan is also a source of sound that needs to be filtered out when measuring fans. For this reason, we insert a securing pad between the frame and the anemometer fan before each measurement and mode setting according to the fixed noise level. This, by the way, also holds the anemometer fan during static pressure measurements.
I have this installed as a back exhaust fan on my Fractal Design Define S. In the front I have three of the Fractal Design’s older dynamic GP14.
This fan has a specific prrrrrrrrrr noise that becomes pronounced above 1100rpm.
I somehow prefer it over the extremely annoying high pitched whine of the Arctic P14 PWM.
My quest for a satisfactory quiet fan over 1000rpm continues.
Are you sure that the noise is not actually being generated by the grille on which the fan is mounted? Maybe it is resonating with the TL-B14 fan and is the source of the unwanted noise. With other fans this doesn’t necessarily have to happen, of course…
Please review the Thermalright TL-C12015B. Maybe the best slim fan after the P12 slim, and important as the range for slim fans is limited.
Wow, Thermalright’s offering is quite impressive in this slim space. 😉

That’s a very nice list of fans. Thanks for sharing! 🙂
Yes, the TL-C12015B looks good. Thanks for the tip! We are adding it to the list and will ask Thermalright for samples when we get the opportunity. No promises, but let’s hope we’ll get to see its tests on here. 🙂
1. For some reason, the positive/negative list in the evaluation section seems empty. Can you check if that’s also the case on your end?
2. On the topic of Thermalright, have there ever been considerations of reviewing some of TR’s CPU air coolers?
I’d love to see some of the detailed analysis you guys do for the likes of the Phantom Spirit 120 Evo, Royal Pretor 130 Ultra or the Peerless Assassin 140, just as examples for their 3 most performant recent models.
Sorry, no idea why this was posted a reply to you (Yamato). It was supposed to be a question to Ľubomír.
Thank you for the heads-up. 🙂
1.) The +/- table really was empty, but everything’s fixed now.
2.) We’re definitely interested in Thermalright coolers, and we already have a sample of the Royal Pretor 130 in the test lab. Their lower representation in our tests is only due to weaker local distribution, but that doesn’t change the fact that we want to cover Thermalright coolers too. The English edition of HWCooling does have global reach.
Is the TL H12-X28 anywhere in the schedule? Looks like a pretty good 120mm ARGB workhorse if the specs are anywhere near accurate
We don’t currently have the TL-H12-X28 fan in our testing plans. I agree its design is extremely attractive, but I’m constrained by limited time. While I believe we’ll eventually get around to testing this fan, I really can’t make any promises right now.
I’m sorry if it has been asked before or if it’s already on the schedule, but could you guys review the Sudokoo Mach140 fan, the Sudokoo Proteus 360 AIO and the Thermalright Stream Vision AIO?
IIRC, Sudokoo Mach is on the schedule, but I don’t know if it’s 120 or 140. 😛
Either will be great. Comparing the 120 with the Phanteks T30 or the 140 with the Arctic 14 Pro will show whether Sudokoo’s product is competitive.
I’m looking forward to it. The aerodynamic design of these fans looks really promising, and based on previous experience, I’d expect the Mach120 to deliver some very attractive results. 🙂
And you can find the TR Stream Vision AIO review here:

😛
Nice! Thank you!
As for Sudokoo fans, we have Mach120 samples in the test lab. Tests of these fans will definitely come out sooner or later. Regarding the Mach140—can’t say yet, we’re not that far ahead, haha. The Proteus and Stream Vision coolers are very good suggestions for future tests as well, but I can’t promise anything for now. We’ll see. 🙂
No problem! I know it’s not possible to review every piece of available gear.
Anyway, thank you for everything you have been doing!
