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.
How we measure power consumption…
Is it worth addressing the power consumption of fans? If you have seven of them in your computer (three on the radiator of the cooler and four for system cooling in the case) and they are also backlit, the power consumption starts at tens of watts. This makes it worth dealing with.
All fans are powered by Gophert CPS-3205 II laboratory power supply. It is passive and virtually noiseless, so it does not distort our noise level measurements. However, for the PWM fans, a Noctua NA-FC1 controller is connected through which the fans are regulated. We also have a shunt between the power supply and the Noctua controller. On it, we read the voltage drop, from which we then calculate the current. However, the voltage on the power supply is set so that 12 V goes to the Noctua NA-FC1. We then also set the exact 12 V to measure the maximum power of the 3-pin linear power supply fans.
In the power consumption tests, we will be interested in the power consumption in fixed noise level modes in addition to the maximum power consumption at 12 V or 100% PWM. That is, at those settings at which we also measure other parameters. Finally, in the graphs you will also find the power consumption corresponding to the start-up and minimum speeds. The difference between these two settings is that at start-up speed you need to overcome the frictional forces, so the power consumption is always higher than at minimum speed. At these, the fan is already running and just reduces power to just before a level where it stops.
These start-up and minimum power consumption data are a substitute for the start-up and minimum voltage information. You often encounter this when reading about fans, but with PWM fans there is no point in dealing with it. And although it is possible to power a PWM fan linearly, it will always perform better with PWM control – lower starting and minimum speeds. Therefore, it would be unfair to compare these parameters for all fans using linear control. That way, fans with PWM would be disadvantaged and the results distorted.
…and motor power
In addition to power consumption, it is important to consider one more parameter that is related to the power supply – the power of the motor. This is usually listed on the back on a label and is often mistaken for power draw. However, the voltage and current indication here is usually not about power draw, but about the power of the motor. The latter must always be well above the operating power consumption. The higher it is, the longer the life expectancy of the fan.
Over time and with wear, fan friction increases (through loss or hardening of the lubricant, dust contamination or abrasion of the bearings, etc.). However, a more powerful motor will overcome the deteriorating conditions of the fan to some extent, albeit at a higher power consumption, but somehow it will cope. However, if the difference between the motor power and the operating power consumption of a new fan is small, it may no longer be able to exert sufficient force to turn the impeller under increased friction due to adverse circumstances.
To test the power of the motor, we set the fan to full power (12 V/100 % PWM) and increase the mechanical resistance by braking the impeller in the middle. This is a higher load for the motor, with which the power consumption naturally increases. But this is only up to a point, until the impeller stops. The power of the motor in our tests corresponds to the highest achieved power consumption that we observed when the fan was being braked.
We use the Keysight U1231A high sample rate precision multimeters to analyse motor power (as well as normal operating power consumption). In addition, the individual samples are recorded in a spreadsheet, from which we then graph the maximum. The final value is the average of three measurements (three maximums).
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!
