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” »

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.

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.
