These solid-state fans will revolutionize cooling in our PCs and laptops

by

With mobile technology growing slimmer yet more potent, it’s vital that we develop sophisticated cooling systems to match this evolution.

Established in 2018, the innovative company xMEMS, renowned for its groundbreaking micro-speaker technology, aims to share this effective solution.

In the year 2024, the compact cooling device, XMEMS µCooling XMC-2400, was unveiled, and it’s anticipated that this tiny active fan will start appearing in various consumer mobile gadgets by the year 2026.

How tiny, you ask? It’s small enough to fit on your fingertip with plenty of space to spare.

In the current state of mobile technology manufacturing, there’s often a choice to make between active and passive cooling methods.

Passive cooling methods encompass various components such as heatsinks, heat spreaders, and vapor chambers; the specific ones used within a device depend on the available interior room.

The devices containing these solutions typically operate without power, and they usually don’t necessitate ventilation. To put it simply, you can liken them to your mobile phone or the Solid-State Drive (SSD) in your computer that cool down passively, without any active cooling systems needed.

This method has seeped into contemporary slim and lightweight Windows laptops such as the Surface Pro 12-inch, which lack cooling fans or vents for its Snapdragon X Plus processor and additional hardware components.

Instead of active cooling, let me explain passive cooling first. This method relies on natural means like radiation and convection to get rid of heat. For example, when you leave your computer without a case, it’s passively cooling itself by simply letting the heat escape into the air. However, active cooling works differently. It uses powered solutions such as fans or liquid systems to actively dissipate heat – think of the fans in your computer or the cooling system inside your laptop or desktop PC that helps them run smoothly even under heavy workloads.

In addressing the predicament posed by slim and lightweight devices that demand active cooling to prevent overheating and thermal throttling, the xMEMS XMC-2400 fan offers a viable solution.

To tackle the challenge of thin and light gadgets necessitating active cooling to avoid heating up and slowing down due to thermal throttling, the xMEMS XMC-2400 fan provides an effective answer.

The microcooling fan designed by xMEMS, claimed to be the first all-silicon chip-based cooling fan for slim, high-performance, AI-compatible mobile devices, has dimensions of 1.08mm in thickness, 9.26mm in length, and 7.6mm in depth.

This chip features eight minuscule Piezo elements that oscillate rapidly enough to generate approximately 39 cubic cm/sec of airflow and 1,000 Pascal of counter pressure. As you can observe in the video demonstration provided, this is no mere jest.

This minute silicon chip, known as SMT-reflowable, is capable of being integrated into electronic devices through the process of soldering.

This item operates silently, and it boasts an IP58 rating, ensuring resistance to both dust and water. Its silicone structure is expected to offer much greater reliability compared to conventional fans.

xMEMS intends to manufacture two distinct designs of the chip, one featuring a top exhaust and another with side vents. This flexibility extends its potential applications. Additionally, the fan boasts bidirectional airflow capability.

In simpler terms, xMEMS considers the XMC-2400 micro cooling fan to be a perfect fit for devices such as smartphones, tablets, virtual reality headsets, portable SSDs, wireless charging pads, and ultra-thin, lightweight laptops.

The fan is minuscule enough to be incorporated into virtually any technology requiring additional cooling.

1. If you’re fond of mobile gaming, a future device with an internal fan like this one would undoubtedly deliver superior sustained performance.

2. Looking to upgrade your compact laptop with a high-performance M.2 PCIe SSD? The XMC-2400 can help prevent throttling without significantly increasing the size of your device.

xMEMS has competition from Frore’s AirJet Mini G2

It’s not just xMEMS that is developing tiny cooling technologies; Frore Systems, who initially launched the AirJet Mini in 2023, has come back with an upgraded version called the AirJet Mini G2.

In simpler terms, Tom’s Hardware reported on the recent release, pointing out that the G2 model has enhanced its cooling system by 50%, all while maintaining the same size as its previous version.

Indeed, it’s significantly bigger than the xMEMS XMC-2400, with dimensions of 2.5mm in thickness, 26.6mm in depth, and 41.25mm in width. Given that it’s designed to manage larger components, this size is quite reasonable.

Although the AirJet Mini G2 may not be compatible with as many devices as the XMC-2400 because of its smaller size, it’s refreshing to have multiple options available in the market.

It’s likely that compact fans similar to these could eventually become commonplace in portable electronic devices. Healthy competition among manufacturers would ultimately be advantageous for consumers.
