Thermalright TL-C12C fan: Also works in reverse

Cooling, Extra tests, Fans | | Ľubomír Samák

So, we have results for a Thermalright fan. While the first attempt (or second, if we count the now-discontinued model X-Silent 120) didn’t quite hit the mark, it’s probably fair to say that this is a more attractive option than the Scythe Kaze Flex II 120. Yes, these two fans are being directly compared because they share an unusual trait – they spin in the “reverse” direction, from left to right. And as you know, most fans spin the other way…

* When reading performance metrics, always account for a certain tolerance. For maximum RPM, a ±10% variance is typically noted, while minimum RPM can vary significantly from unit to unit – sometimes manufacturers even allow for ±50%. This must also be properly factored into airflow, static pressure, and noise level values. If a table cell lists only one value, it always refers to a situation at maximum RPM achieved at 12 V or 100% PWM duty cycle. The lower performance limits are not disclosed by the manufacturer in such cases. The price in the final column is always indicative only.
** Price is calculated per unit, but the fan is not sold individually. It is only available as part of a three-pack that also includes an ARGB hub.

Fan frame daisy-chaining trend. When is it (not) helpful

Analysis, Fans | | Ľubomír Samák

Easier installation? Yes, that’s why it’s done. Daisy-chaining fans using contacts in their frames is great, but it often also comes with pitfalls that reduce “cooling efficiency”. Manufacturers deal with this in different ways. One does it technically one way, another differently. In any case, they know that a frame that is too thick means less space for the blades. And that does not improve airflow per unit of noise. Read more “Fan frame daisy-chaining trend. When is it (not) helpful” »

Arctic BioniX P14 A-RGB: Elegant daisy chaining is just the beginning

Cooling, Extra tests, Fans | | Ľubomír Samák

High cooling efficiency is the foundation, but with the BioniX P14 A-RGB fans, Arctic has also made efforts on other fronts. In addition to the clever daisy-chaining method (with the aim of reducing cabling to a minimum), this includes, for example, illumination as intense as possible. The light is guided not only through the entire impeller, but also through the surface of the frame, from the side. There are light guides in these areas as well.

And with very clever daisy‑chaining from one fan to the next. This is what can fill in the ellipsis in the headline. The aerodynamic efficiency remains top‑tier, built on a design that Arctic revised some time ago (with the P12 Pro fans), but which can still be considered “new.” The BioniX P12 A‑RGB fans certainly are (new), and in this in‑depth analysis we focus on how they work.

  1. A potentially huge problem for this fan is its longevity. I’ve seen quite a number of reports of them failing in large numbers only after a few months of usage, presumably due to bearing failure. Have you seen any signs of this happening on your units?

    Even when ignoring this issue, I don’t see it being particularly competitive vs fans like Endorfy Stratus and Arctic P12. While airflow per price vs no obstacles is high, but the value decreases greatly if you look at airflow per price vs radiators, for example.

    1. Even though I cannot assess longevity, I can assess the ratio of airflow to price. And especially when it comes to the ratio airflow to price on radiators, this ratio speaks in favor of the TL-C12C compared to the Stratus. The P12 is from another world, nothing can be compared to it 😀 . Moreover, I counted with the price that Ľubo states in the specification (in €). If we took the price of a three-pack even the P12 would sweat.

      I would say that overall the TL-C12C is quite comparable to the Stratus (except for the lifespan, which I can’t assess). 😉

        1. Yes, the price of the TL-C12C in the triple pack is extremely attractive. However, I assume that a fan hub will not be included in the standard accessories, as is sometimes the case with more expensive models. Here it will probably rely on the possibility of daisy-chaining and connecting all three fans to one header on the motherboard or case (if the case has its own hub). 🙂

        2. You’re right, I was not aware of the fact that the triple pack is priced so low. If C12C works well long term, I can see them being quite attractive.

    2. Good point. Unfortunately, we cannot assess lifespan. I’ve played around with the idea of creating some form of methodology based on “accelerated aging”, but under our conditions, that would not be easy… Recently, my colleague and I talked about fluid dynamic bearings and yes, the quality level can vary. This is also reflected in the wide range of MTBF/MTTF values… so yes, in the case of the TL-C12C, it’s probably a bit weaker here, but that probably also applies to the Stratus 120 PWM fans. Those are also low-end, but aerodynamically excellent, and I think both deserve the Smart Buy! award (the fans). Arctic P12, as Bufo points out, is “from another world”, but we should keep in mind that this might not be the case for much longer. It depends on how long Arctic continues to sell and supply them to third-party retailers. 🙂

    1. Thanks for the clarification. You’re right — not all FDBs are created equal. That’s also why the range of MTBF values (with FDB) is so wide. 🙂

    2. as one fictional character said 😉

      Bearing is bearing.
      Rifle, Fluid, Hydro …
      Makes no difference.
      The degree is arbitrary.
      The definition’s blurred.

      or something like that … 😀
      (message for Ľubo…you don’t have to resolve the differences…this is just for relief) 😀

    3. Just want to say THANK YOU! This info doesn’t show up anywhere nor prominently in search engine results when researching lifetime of these Thermalright fans. Now it also makes sense why the E12B V3 model stops after 4 seconds on max RPM when the power is cut. With an Arctic P14 I saw it’s over 12 seconds. Makes sense now. Feeling pretty disappointed how misleading Thermalright is with the “FDB” claim…
