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.

Zero RPM illuminated Arctic fans are now also available in 140 mm

Cooling, Fans, News | | Ľubomír Samák

Arctic released the P12 fans with (A)RGB first in a more widespread 120 mm format. Now, however, the range is also expanding to include 140 mm models, which should achieve higher airflow compared to the smaller variants. The Swiss manufacturer claims that the rotor is also well suited for operation on liquid cooler radiators. In addition, the P12 PWM PST (A-)RGB fans are also characterised by a passive mode.

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” »

Specs of the first Aorus fans look more than good

Cooling, Fans, News | | Ľubomír Samák

Gigabyte will sell the Aorus fans as standalone products. News of this surfaced earlier this summer, at the launch of the new AIO coolers , but now it’s all in black and white. And admittedly, this may not be a “fancier” hardware category (Aorus). The motors have three-phase torque, a lubricant with supposedly superior durability, and finally, the rotor design looks sensible. Read more “Specs of the first Aorus fans look more than good” »

Thicker fan, better properties? Phanteks has a 30 mm fan

Cooling, Fans, News | | Ľubomír Samák

Phanteks has released a 120-millimeter fan with an atypical thickness of 30 mm. Thanks to such a profile, the rotor with the same cross-section can have a larger blade area. And since the blade shape on the new Phanteks fan resembles that of the Noctua NF-A12x25 PWM, there was immediate speculation about “the new king” and so on. However, this may not be so clear for several reasons. Read more “Thicker fan, better properties? Phanteks has a 30 mm fan” »

TL-B12 Extrem: New fan by Thermalright with 3,150 rpm

Fans, News | | Ľubomír Samák

A remarkable fan—TL-B12 Extrem—has appeared among the products on Thermalright.com. It will be one of the few options with very high speed and therefore high static pressure and air flow. According to specifications, it even defeats the industrial variant of the Noctua NF-F12 fan (iPPC-3000 PWM) in some aspects. However, the TL-B12 Extrem could be cheaper.

Alphacool has new fans: High speed and low profile

Fans, News | | Ľubomír Samák

Characteristic for the Alphacool brand are excellent radiators and various accessories for liquid coolers. However, the offer of fans is relatively narrow. That is changing a bit now. The company is expanding its offer in this direction wisely, with unusual designs. One of the new additions is a low-profile 120 mm and the other two fans excel at extremely high speeds, which are not common with computer fans.

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.
