This means that all coolers are equally well integrated, because each has a different exit angle and this is exactly what can be compensated for. The “honeycomb” behind the fan was recommended to us by Black Noise and the cooling manufacturer. Each of the chambers is also expediently lined with nubby foam and designed in terms of material technology so that there are hardly any disturbing influences. Decoupling is of course very important, and we were fortunate to have expert help in calculating the volume for the chambers. In the picture we can see the middle partition between the two chambers, which supports the fan and also the radiator. The data on volume flow (“throughput”) and static pressure in the data sheets are of no help if something works well on a slim radiator and fails completely on a 45 mm radiator. Not every model is suitable for all radiator thicknesses and many a supposed powerhouse loses so much pressure on radiators that it can hardly be called suitable.
Measuring chamber with sound level control (measurement takes place separately)Ĭurrently, there is always the question of what characteristics such a 120 or 140 mm fan really has. Of course, we are not a standardization company or the TÜV, but we try to measure everything as accurately as possible, which still remains within a reasonably affordable range.

But that’s enough for all areas of what concerns the PC self-construction and -conversion. Of course, what we can measure from now on only meets semi-professional requirements, even though all measuring instruments have been calibrated in an elaborate and cost-intensive way. How it all works and what we can and cannot measure in the end, you will learn in this article.īy now most of it has materialized really nicely, also with a lot of good feedback from the community and technical help from some industry partners. The heavy and solid body made of thick MDF boards is screwed, glued and sound-insulated. Here the colleague Pascal Mouchel has done a great job and the result as the model “Sarcophagus I” can be seen in the meantime. Maybe that the way they measure it in the test, the HF-14 is more spread out than the HP-14 so the results are different.And since there is currently no source that offers realistic and usable data, even in comparison, we have invested a lot of time and money and simply developed our own fan measuring station with the advice of a cooling unit manufacturer and then calibrated it.
I find it really weird that the HF-14 provides less CFM than the HP-14. I don't speak Italian either, but use either their built-in translator on the top left of the article or Google translate.
And I wish more people did comprehensive fan reviews so we had more information. I wonder if they were measuring in near the center or something (the HF fans throw their air out really hard on the corners), I'm sorry to say I don't speak Italian. Like 8dB lower than even fractal's specs. They showed that for both series, which having both fans not only seems wrong but contradicts everything else I have seen on the internet (and in person)įurthermore their noise levels were way lower than I'd expect to see.
