Trade shows like Computex always bring out their fair share of oddities, and this year was no exception, with one of the highlights being a Corsair PC case with no fewer than 24 fans.
As one of a handful of companies offering really big desktop PC cases, Corsair was demonstrating its new creature: the 9000D Airflow. At 90 liters in volume – which is twice the size of regular PCs and 1.5x the volume of a typical car gas tank – the colossal case is bigger than ever. It's so big, in fact, that it can house two systems: a full-size ATX (or smaller) system, as well as a separate Mini-ITX system.
The most eye-catching aspect of this PC case (besides its large size, of course) is that it can house as many as 22 fans in addition to two liquid cooling systems. As the name of the 9000D Airflow implies, all of those fans are meant to create as much airflow as possible. And yet, because there are so many fans inside, they do not have to run at a high RPM to move the requisite amount of air, so the 9000D Airflow is quieter than its size otherwise lets on.
To simplify installation of all these fans, the chassis consists of adjustable mounting points on a sliding rail, making the case versatile for any build requirements. The 9000D includes two InfiniRail systems, one at the top (holding six fans) and one at the front, each capable of holding up to eight 120mm fans. Adding fans on the sides and rear increases the total to 24. For those using 140mm or 200mm fans, the InfiniRails can be adjusted by unscrewing and repositioning them based on marked guidelines, allowing for a customized setup despite fitting fewer larger fans. The flexibility of the InfiniRail system enables unique fan placement, enabling the freedom to tailor the cooling configuration to specific needs.
The case design also includes 30mm of clearance behind the motherboard for efficient cable management, making it well-suited for creating clean, organized, and powerful builds.
Besides its may fans, the 9000D Airflow also offers 11 drive bays, plenty of front I/O ports (four USB Type-A, two USB Type-C, audio connectors) with RGB lighting controlled through the iCue Link system. The spacious design allows for comprehensive component compatibility and expansion.
Corsair's Airflow 9000D will be available later this year.

While the new CAMM and LPCAMM memory modules for laptops have garnered a great deal of attention in recent months, it's not just the mobile side of the PC memory industry that is looking at changes. The desktop memory market is also coming due for some upgrades to further improve DIMM performance, in the form of a new DIMM variety called the Clocked Unbuffered DIMM (CUDIMM). And while this memory isn't in use quite yet, several memory vendors had their initial CUDIMM products on display at this year's Computex trade show, offering a glimpse into the future of desktop memory.
A variation on traditional Unbuffered DIMMs (UDIMMs), Clocked UDIMMs (and Clocked SODIMMs) have been created as another solution to the ongoing signal integrity challenges presented by DDR5 memory. DDR5 allows for rather speedy transfer rates with removable (and easily installed) DIMMs, but further performance increases are running up against the laws of physics when it comes to the electrical challenges of supporting memory on a stick – particularly with so many capacity/performance combinations like we see today. And while those challenges aren't insurmountable, if DDR5 (and eventually, DDR6) are to keep increasing in speed, some changes appear to be needed to produce more electrically robust DIMMs, which is giving rise to the CUDIMM.
Standardized by JEDEC earlier this year as JESD323, CUDIMMs tweak the traditional unbuffered DIMM by adding a clock driver (CKD) to the DIMM itself, with the tiny IC responsible for regenerating the clock signal driving the actual memory chips. By generating a clean clock locally on the DIMM (rather than directly using the clock from the CPU, as is the case today), CUDIMMs are designed to offer improved stability and reliability at high memory speeds, combating the electrical issues that would otherwise cause reliability issues at faster memory speeds. In other words, adding a clock driver is the key to keeping DDR5 operating reliably at high clockspeeds.
All told, JEDEC is proposing that CUDIMMs be used for DDR5-6400 speeds and higher, with the first version of the specification covering speeds up to DDR5-7200. The new DIMMs will also be drop-in compatible with existing platforms (at least on paper), using the same 288-pin connector as today's standard DDR5 UDIMM and allowing for a relatively smooth transition towards higher DDR5 clockspeeds.

MemoryAs LPCAMM2 adoption begins, the first retail memory modules are finally starting to hit the retail market, courtesy of Micron. The memory manufacturer has begun selling their LPDDR5X-based LPCAMM2 memory modules under their in-house Crucial brand, making them available on the latter's storefront. Timed to coincide with the release of Lenovo's ThinkPad P1 Gen 7 laptop – the first retail laptop designed to use the memory modules – this marks the de facto start of the eagerly-awaited modular LPDDR5X memory era.
Micron's Low Power Compression Attached Memory Module 2 (LPCAMM2) modules are available in capacities of 32 GB and 64 GB. These are dual-channel modules that feature a 128-bit wide interface, and are based around LPDDR5X memory running at data rates up to 7500 MT/s. This gives a single LPCAMM2 a peak bandwidth of 120 GB/s. Micron is not disclosing the latencies of its LPCAMM2 memory modules, but it says that high data transfer rates of LPDDR5X compensate for the extended timings.
Micron says that LPDDR5X memory offers significantly lower power consumption, with active power per 64-bit bus being 43-58% lower than DDR5 at the same speed, and standby power up to 80% lower. Meanwhile, similar to DDR5 modules, LPCAMM2 modules include a power management IC and voltage regulating circuitry, which provides module manufacturers additional opportunities to reduce power consumption of their products.

It's worth noting, however, that at least for the first generation of LPCAMM2 modules, system vendors will need to pick between modularity and performance. While soldered-down LPDDR5X memory is available at speeds up to 8533 MT/sec – and with 9600 MT/sec on the horizon – the fastest LPCAMM2 modules planned for this year by both Micron and rival Samsung will be running at 7500 MT/sec. So vendors will have to choose between the flexibility of offering modular LPDDR5X, or the higher bandwidth (and space savings) offered by soldering down their memory.
Micron, for its part, is projecting that 9600 MT/sec LPCAMM2 modules will be available by 2026. Though it's all but certain that faster memory will also be avaialble in the same timeframe.
Micron's Crucial LPDDR5X 32 GB module costs $174.99, whereas a 64 GB module costs $329.99.
