Volume flow vs. sound pressure level
Every customer has different premises, of course, and you get a very appealing performance in the case with a huge rev band here. The Thermalright TL-B12 Extreme clearly beats the reference in terms of flow rate and noise development (except for the mechanically induced noise). However, flow rates and speeds are two different things, because in the end it is also the ear that decides. On a radiator, no matter what thickness, the positive overall picture is definitely maintained. Except for the annoying clacking, of course. In order to still be able to measure below 500 rpm, we had to switch to DC control below 20 CFM (red curve sections).
Those who install the fan must therefore also pay attention to structure-borne noise and vibrations, which can quickly find a resonator and then put the fan acoustically on the sidelines. Such things are also precisely the reason why we work with a large-volume and very rigid chamber rather than a thin and long wind tunnel. This also applies to the end user, who may please pay attention to a good decoupling here. The rubber applications used are usable, but still not optimal when in doubt.
Volume flow and speeds
We again recognize the red areas of the DC control. Otherwise, we also see that you can already achieve a higher throughput with lower speeds. It was this circumstance that made us like the product per se, and we continued to test it until the end, even though the clacking noise kills your nerves.
Conclusion
Whether and how you can still get this crunchy cow off the ice, I can’t say myself yet. If we have the opportunity for a retest, we will of course do so. In the current state of both fans, however, one must rather advise against a purchase. Here we need to talk to Thermalright itself, as well as the German importer. So it remained really exciting. However, I also have to add that we explicitly received the fans from Asia for a public test (and not as prototypes). Seen in this light, it was bad luck for Speedy & Co. that we took a closer look and didn’t just lay our hands on them. But even that can go wrong.
