The weirdest cooling fan ever: Install an additional fan to cool the... Fan!- Photo 1.

Arctic, a brand specializing in the manufacture of radiators, fans, etc., has just introduced a brand new line of cooling fans for servers, named S12038-4K and S12038-8K. What makes this fan line immediately stand out is the unique design with seven additional blades located in the center, creating a "fan within a fan" effect. With its outstanding static pressure generation, it is one of the top fans for servers, although Arctic seems to be quite secretive in promoting this new product.

Impressive Specifications of S12038

The S12038 scores in many respects with its impressive spec sheet. The advertised maximum power consumption is 3.96W, which is 12% lower than the nearest competitor in the server fan segment.

This fan series produces a static pressure of 11.45 mmH₂O, which is 3 to 6 times higher than Arctic's conventional fan series. With such high pressure and airflow, the S12038 is almost the best in the server cooling fan segment. As the name suggests, the fan is available in two versions with a maximum rotation speed of 4,000 RPM or 8,000 RPM.

The S12038 uses a dual ball bearing design, instead of the usual fluid dynamic bearing. This helps to improve the operating efficiency and durability of the fan.

The additional propeller in the center of the main rotor is designed to cool the spindle, which reduces the motor temperature by 5-10°C, according to Arctic's documentation (these documents have minor differences). Arctic claims that this shaft cooling doubles the effective life of the fan.

In addition, the fan is also equipped with a dust protection sticker for the center blade, which helps protect in dusty environments. However, covering this unique propeller design can detract from the product's unique aesthetic.

Not for regular PCs

If you want to use the S12038-4K for decoration or cooling for a regular PC, be aware of some limitations. The fan has a height of 38mm, which is 11mm taller than a standard PC fan, and there is no rubber cushion to reduce noise and vibration. This causes the S12038 to produce higher noise and vibration levels, which are not suitable for setups that require quietness such as consumer fans.

Although the S12038 brings outstanding performance in the server fan segment, Arctic is not very interested in promoting this product. Arctic's Reddit social media posts are often deleted or ignored, press releases are hard to find, and few outlets report on the actual performance of the product.

At a price of $14.99 on Amazon, the S12038 series of fans is suitable for 3U+ server systems or workstations that need high static pressure. It is an ideal choice for those looking for a powerful and durable cooling solution.

NVIDIA introduces new AI supercomputer, super compact, "student" price - as cheap as an office laptop but extremely useful

Image
  With its super cheap price, this AI supercomputer from NVIDIA is especially suitable for AI research enthusiasts with limited finances, such as students or small companies. NVIDIA recently introduced the Jetson Orin Nano Super development kit, the successor to the Jetson Orin Nano kit from 2022. This compact AI supercomputer can fit in the palm of your hand, including an 8GB Jetson Orin Nano system module and a reference board. In terms of performance, the Jetson Orin Nano Super achieves 68 trillion operations per second (TOPS), a 70% increase over the previous generation. NVIDIA also claims a 1.7x improvement in generative AI inference performance and a 50% increase in bandwidth, reaching 102GB per second. The CPU frequency is now 1.7GHz, a modest increase from the previous generation's 1.5GHz. IA claims that Jetson Orin Nano Super benefits all common generative AI models, including large language models (LLMs), visual language models, and vision converters. Jetson Orin Nano Sup...

Experience with the Cooler Master Storm game controller: Comfortable grip, battery life up to 40 hours, but there's one unfortunate drawback.

Image
 This is a good gaming solution for Windows, Mac computers, or mobile devices like Android, iOS, iPad, but it will be difficult to use with PS5! Mouse and keyboard are considered the most optimal accessories for gaming, but there are still gamers who highly value the experience of playing with a controller, similar to console gaming. That's why gaming brands continue to release new controllers, including Cooler Master with the Storm Controller we have here. The controller is packaged in a small cardboard box and is quite attractively decorated. Inside the box, besides the controller, we have a user manual and a USB-C to USB-A cable. This controller comes in two color versions: Black - Purple and White - Purple, which we have here. This color scheme reminds me of the character Frieza from the Dragon Ball series! In terms of design, the Cooler Master Storm has a shape closer to the Xbox controller than the PlayStation 5 - slightly rounded and 'chubby'. This design feels comfo...

Experience with AirPods Pro 2 USB-C: The upgrade may seem small, but it's the most valuable one yet.

Image
 Launched at the Wonderlust event, the new generation of AirPods Pro may have received less attention, partly because they were overshadowed by the "glow" of the iPhone 15 and Apple Watch 9/Watch Ultra 2, or perhaps because people think that just changing the charging port to USB-C is really not enough However, just one day after this event, I was fortunate enough to be invited to try out the new version and found that it deserves more recognition, especially the new features on firmware 6A301 (only usable when upgrading to iOS 17, which of course had not been released at that time). Adaptive Audio and Conversation Awareness - features I've been waiting for a long time After three generations of regular AirPods, Apple released the Pro version in 2019 with active noise cancellation (ANC). This was considered a significant advancement in Apple's "music playing" system, allowing it to compete with other market rivals. Moving on to the second generation of the P...
