Noctua NF-P12 redux-1700 PWM: Not every low-end is the same

Cooling, Extra tests, Fans | | Ľubomír Samák

In this test, we’ll take a look at Noctua’s anticipated first representative and how it ranks next to other fans. We’ll start from the bottom with the most affordable one from this Austrian company. It should be noted that Noctua views this class of fans slightly differently than other brands, and has the base perched very high. However, there is one BUT, which is rather insignificant, but still “lifted some people out of their chairs”. Read more “Noctua NF-P12 redux-1700 PWM: Not every low-end is the same” »

SilentiumPC Fluctus 120 PWM: “Miracle” fan from the Fera 5

Cooling, Extra tests, Fans | | Ľubomír Samák

SilentiumPC presents the Fluctus 120 PWM as its very best fan. But, to beat the whirring Sigma Pro 120 PWM and the obviously sketchy Sigma Pro Corona RGB 120 is relatively simple. The company’s marketing, however, talks about psychoacoustic optimizations. And while there’s no reason to smirk (psychoacoustics is a legitimate scientific field), there were some imperfections that the Poles didn’t avoid.

MSI MEG Silent Gale P12: A dominant all-rounder for a price

Cooling, Extra tests, Fans | | Ľubomír Samák

While the Silent Gale P12 isn’t the first fan in MSI’s lineup (like the Strix XF120 from Asus), it beats anything previous from the company by a mile. This is by the efficiency of the rotor, which is suitable for radiators as well as for a case, but also by the overall robust design. There’s a big, powerful but quiet motor, and you won’t even know about the hydrodynamic bearings. Read more “MSI MEG Silent Gale P12: A dominant all-rounder for a price” »

Asus ROG Strix XF120: An excellent fan, but only in some ways

Cooling, Extra tests, Fans | | Ľubomír Samák

The first and still the only Asus fan that is on sale individually may be a good choice. But you can also get burnt. It depends on what you want to use it for. In the right context, it gives attractive results, and the impression of a very decent fan is spoiled mainly by pointless design details or sugar-coating the specs. Anyway, you can see that compared to the more ordinary fans from the last test, the Strix is a bit of a different class. Read more “Asus ROG Strix XF120: An excellent fan, but only in some ways” »

Big test of 120 mm fans. We known everything about eight of them

Cooling, Extra tests, Fans | | Ľubomír Samák

To write that we have something mapped out to the last detail is perhaps too bold, but after proper preparation, few pieces of hardware are as easy to evaluate as fans. Of course, this had to be preceded by long preparations, developing a methodology, but you already know the story. What you don’t know yet is the first fruit, or rather the results of Akasa, SilentiumPC, SilverStone, Xigmatek or more exotic Reeven fans. Read more “Big test of 120 mm fans.

We tried a DIY silon dust filter instead of traditional nylon. Result?

Cooling, Extra tests, Fans | | Ľubomír Samák

Socks, stockings or tights made of silon also attract uses other than on our legs. Enthusiasts can use the material to make, for example, a dust filter for a PC fan. It’s effectiveness then depends on the thickness of the silon fibre. However, tests show that whatever type you use, it is a rather unsuitable solution. And it’s also difficult for robbers who don’t worry too much about the mask and just need a visit to the drugstore before the job.

The Akasa GRM120-30 foam filter works better than it seems

Cooling, Extra tests, Fans | | Ľubomír Samák

After analyzing the nylon and plastic dust filter, we now add a test of the “foam” dust filter. The latter has a slightly more complex construction. It consists of several parts and is kind of like a jigsaw puzzle, the elements of which even improve the aerodynamics in some ways. We go through everything in detail, and although we approached this type of filter with a bit of a bias, it comes out in a good light in the end. Is a foam dust filter better than a nylon one?

Analysis: a hexagonal grille is no match for a circular one, in any way

Cooling, Extra tests, Fans | | Ľubomír Samák

Why do cases and PSUs almost always have impractical cut-outs in the grille in front of fans for air passage? Whether this is due to indifference to an all-round honest product or ignorance of how inefficient a solution it is, remains a mystery. But we have devised a comparative test which refers to drawbacks of the hexagonal grille. Compared to the non-restrictive circular ones made of wires, the differences are significant.

Test: Nylon vs. plastic dust filter. Which restricts fans less?

Cooling, Extra tests, Fans | | Ľubomír Samák

The vast majority of computers use two types of dust filters – a fine nylon one and a coarser plastic one. The fact that the plastic filter lets more through and is less efficient in this respect is already apparent from the eye, as it has a coarser mesh. But do you know which one degrades the performance of the fan more and by how much? One even “wheezes”, which is nicely indicated by a detailed noise analysis at 240 sound frequencies.

Complete analysis of the final wind tunnel for fan testing

Cooling, Extra tests, Fans | | Ľubomír Samák

The introduction to this article has been rewritten several times. The original versions resorted to describing the adverse events that caused the long-announced fan testing to be so dramatically delayed. But the text was always dreadfully boring… the important thing is that everything managed to make it to the start. But before the starting gun, come take a thorough walk around the track where the measurements will take place. Read more “Complete analysis of the final wind tunnel for fan testing” »

System cooling in the spotlight. What to increase/decrease?

Cooling, Extra tests, Fans | | Ľubomír Samák

Do you know how many fans do you need and what speed they should run at to achieve the optimal cooling of your PC case? Is it better to induce positive pressure, negative pressure, or balanced airflow? Are four fans with less RPM more effective than two with more RPM? We can answer all these questions by providing you results of more than 70 tests which also include the monitoring of the heating of power supply circuit of CPU and GPU.
