The Asus ROG Crosshair X870E Glacial arrives as a premium AM5 motherboard that doesn’t just follow the crowd—it redefines it. From a proprietary AIO cooler connector to hidden PCIe slots and a magnetic RAM fan, this board is packed with features that either push boundaries or raise eyebrows. Yet beneath the flashy design lies a platform that demands careful consideration for power users, where performance restrictions and niche features clash with real-world usability.
At first glance, the X870E Glacial doesn’t stand out—at least not in the way most enthusiasts expect. Pre-installed Wi-Fi drivers, while a rarity in high-end boards, aren’t the headline act here. Instead, Asus has doubled down on its EZ PC DIY philosophy, refining tools that should make assembly and upgrades less frustrating. The M.2 slots now feature quick-release heatsinks and SSD mounts, while PCIe slots can be secured with a magnetic lock, eliminating the need for screws. These are practical improvements that could trickle down to mid-range boards, but they’re just the beginning.
The Good: Thoughtful (If Expensive) Upgrades
A standout innovation is the board’s new proprietary AIO cooler connector. Asus has long relied on PWM headers and USB cables for liquid cooling, but this board replaces them with a row of large pins/pads. The idea is simple: eliminate cable clutter and simplify installation. However, the catch is that Asus’ own AIO coolers are among the most expensive on the market, making this a feature reserved for those already invested in the ecosystem.
More contentious is the inclusion of a magnetic RAM fan, bundled with the board. The fan snaps onto the DRAM sticks via magnets, promising a cleaner installation than traditional screw-based coolers. But its effectiveness is debatable. Unless you’re pushing DDR5 modules to extreme overclocks, memory temperatures rarely justify active cooling. Worse, the fan’s intake sits near the PCIe slot, meaning it could recirculate hot air from a graphics card rather than provide meaningful cooling.
The Odd: Hidden Slots and Performance Caveats
The X870E Glacial’s most polarizing design choice is its hidden PCIe slots. Two magnetically attached plates cover the expansion slots by default, marketed as a way to clean up cable management or create a decorative display. In practice, this means you can’t install a graphics card without removing the plate—or finding a spare metal surface to mount it elsewhere. It’s a gimmick that adds no real value, especially since the bottom plate does hide useful headers, but the top one serves no functional purpose.
Performance enthusiasts will also find limitations in the board’s storage and PCIe configuration. The ROG Hyper M.2 card, which slots into a PCIe x16 lane, forces the top PCIe slot to operate in x8 or x4/x4 mode if occupied. Meanwhile, the ROG Q-DIMM.2—an accessory that adds two M.2 slots to the board—only offers one PCIe x4 slot, with the second running at x2. Even worse, using the board’s second M.2 slot while a USB4 device is connected halves its speed. These aren’t unique to the Glacial, but they’re frustrating when paired with a board that advertises seven NVMe slots.
Who Should Buy It?
The X870E Glacial isn’t for everyone. Its $1,200 price tag, proprietary features, and performance tradeoffs make it a niche product. It appeals to those who prioritize aesthetics over pragmatism, or to AM5 enthusiasts already deep in Asus’ ecosystem. For most, the magnetic RAM fan and hidden slots will feel like gimmicks, while the storage bottlenecks and AIO cooler dependency add unnecessary complexity.
Yet, there are merits here for the right user. The EZ PC DIY improvements are genuinely useful, and the proprietary AIO connector—while limiting—could set a new standard if adopted more widely. Whether these innovations justify the cost remains to be seen, but one thing is clear: the X870E Glacial isn’t just another motherboard. It’s a bold experiment in design, even if not all of its ideas land.
