Arctic P12 PWM PST A-RGB: Hoop? Anti-rumble rescue

Cooling, Extra tests, Fans | | Ľubomír Samák

The biggest shortcoming of Arctic’s original P-series fans is the rumbling sound profile. The manufacturer realized this and decided to do something about it. Sensibly, by implementing a hoop to eliminate the critical vibrations that are the source of the annoying acoustic profile. The implementation turned out well, and already the P12 A-RGB shows how much quieter it is compared to the older P12 model. And the list of improvements doesn’t end there.

Dynamic pressure. How does it relate to other fan parameters?

Analysis, Fans | | Ľubomír Samák

Pressure here, pressure there. Omitting the adjective and not clearly specifying what type of pressure is being referred to can lead to all sorts of misunderstandings. Especially when in fan terminology, the word pressure is usually associated with static pressure. Not infrequently, however, dynamic or total pressure is meant. Complicated? Not really, you just need to be clear about what is being talked about and learn to read between the lines a bit. Read more “Dynamic pressure. How does it relate to other fan parameters?” »

Scythe Kaze Flex II 120 Slim: Well balanced SFF fan

Cooling, Extra tests, Fans | | Ľubomír Samák

Low-profile fans are a special category, but sometimes they are unavoidable in more confined spaces. For technical reasons, it’s always about compromises compared to more respectable fans of normal thickness, but their weight can vary. If the Arctic P12 Slim and Alphacool SL-15 don’t fit your needs, the Scythe Kaze Flex II 120 Slim may be the closest thing to what you’re looking for.

Proper wind now in DeepCool PC cases (CH560)

News, PC cases | | Ľubomír Samák

DeepCool addresses the biggest weakness of the older CH series cases – weaker cooling – in a rather selective way. Namely by preinstalling four fans (instead of one). This is no emergency solution, and the models used are based on a design that dominates the ARGB LED fan rankings in terms of efficiency. The new CH560 cases should thus feature impressive cooling performance in addition to a spectacular look. Read more “Proper wind now in DeepCool PC cases (CH560)” »

Totally simply: What is fan static pressure and what does it say?

Analysis, Fans | | Ľubomír Samák

A trivial topic for some, for others something they didn’t understand as well as they should have. This is also indicated by various activities on discussion forums, including posts like “airflow is irrelevant, you mainly need high static pressure on a radiator”, which somewhat points to a connection of wrong contexts. In this article we will discuss very simply, with examples, what static pressure is and how to grasp it correctly. Read more “Totally simply: What is fan static pressure and what does it say?” »

Intel LGA 1851: No changes and ending support for current coolers?

CPU coolers, News, Processors | | Ľubomír Samák

There are reports that the upcoming Intel LGA 1851 socket will have different cooler requirements. This is even while maintaining the same physical dimensions of the mounting holes or processors as such. A forceful way of selling new coolers? This may not be the case and the real reason may be purely technical. And we probably have some idea why processors from the Arrow Lake generation onwards will benefit from more downforce.

Seasonic MagFlow 1225 PWM, the “King of Controversy”

Extra tests, Fans | | Ľubomír Samák

The design details here not only look fascinating, they really are. That is, except for one “little thing” that makes the MagFlow 1225 PWM unable to play an equal game with the top 120mm fans, even though it seemingly has all the prerequisites to do so. But at least the Seasonic fan has the added value of a very convenient installation: magnet here, magnet there, no cables in sight. Read more “Seasonic MagFlow 1225 PWM, the “King of Controversy”” »

More heat, more cooling. The Enthoo Pro 2 server edition is out

News, PC cases | | Ľubomír Samák

Phanteks returned to its Enthoo Pro 2 case and tweaked a few things within the internal layout that will appeal especially to the server clientele. Key among them is support for larger motherboards with multiple PCIe slots, while still keeping the same case volume. Because of the assumption of high power draw of such a build, the cooling options are also more intensive, and for greater reliability there is again the possibility of installing server grade PSUs.

DeepCool Assassin IV cooler officially. Tests are close

Cooling, CPU coolers, Preview | | Ľubomír Samák

Perhaps the boldest dual-tower cooler design in a decade is becoming a retail market reality. We’ve already written about the preparations for the Assassin IV, but now we have more details, there’s even a test sample in our editorial office already. Let’s pass the wait for the test results by philosophising about not all the elements that can positively or negatively shape cooling efficiency. Read more “DeepCool Assassin IV cooler officially.

Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw

Extra tests, Processors | | Ľubomír Samák

The most popular Ryzen 7000 with 3D V-cache obliterates competition in its targeted environment. Intel doesn’t measure up to the Ryzen 7 7800X3D in a comparable price range in terms of speed, and even if someone disregards price and sees the Core i9-13900K(S) as a an apt competitor, when comparing power draw, everyone’s appetite for Intel will go away. Their efficiency is… incomparable, as each is at a different end of the spectrum. Read more “Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw” »

Third time’s the charm? Scythe has the Fuma 3 CPU cooler

Cooling, CPU coolers, News | | Ľubomír Samák

One of the youngest “brands” or series of Scythe coolers – Fuma – is growing with a new model. The Fuma 3 builds on its predecessors with a dual-tower heatsink design, and hopefully with even higher cooling efficiency. Dimensions haven’t changed much between generations, but some fins have grown and weight has increased. Regarding this cooler, Scythe is talking about a new flagship with aerodynamic optimizations.

ASRock B650E Taichi motherboard – breaker of several records

Extra tests, Motherboards | | Ľubomír Samák

The AMD B650E chipset is a compromise solution to some extent, but the ASRock Taichi motherboard that is based on it makes an ultimate impression. And it’s not just a “feel”, it really is that… The VRM of the CPU didn’t fit in our thermal image with the standard procedure. There are a few quirks and things that you might find it worth tweaking, but those are usually related to other things, like the more modest chipset features.

In vivo fan tests: 14 models in system positions

Cooling, Extra tests, Fans | | Ľubomír Samák

Here and there we come across the opinion that it is advisable to test fans in real life conditions, which we can easily refute. At the same time, we understand that a layman can best identify with the differences in component temperatures that arise precisely due to different fan airflows. To help you see the correlations of such tests with results from “unnatural” environments, here’s something we remembered. Read more “In vivo fan tests: 14 models in system positions” »

Arctic tweaked the P14 Slim PWM PST fan, but didn’t mention it

Cooling, Fans, News | | Ľubomír Samák

If you bought the P14 Slim PWM PST some time ago (and by that I mean earlier this year), its design differs from its current form. And quite significantly so. It is in fact that it has quietly advanced to the second revision. But it did so so quietly that many, including us, missed it. What are the changes and how do you identify the new version so that you don’t order the older, inferior one? Read more “Arctic tweaked the P14 Slim PWM PST fan, but didn’t mention it” »

Do you like small GPUs? Gigabyte RTX 4060 Windforce OC 8G details

Graphics, Preview | | Ľubomír Samák

Nvidia’s smallest, lowest-power, cheapest, and possibly most efficient Ada Lovelace GPU is already a reality in GeForce RTX 4060 graphics cards. Thanks to the low power draw, even very small designs with excellent compatibility with surrounding components are possible. The Gigabyte Windforce OC 8G, which does not outweigh even a half-liter can, is one of these. Read more “Do you like small GPUs? Gigabyte RTX 4060 Windforce OC 8G details” »
