ASUS Chromebook Flip CX3 (CX3400)

Updated on January 26, 2026

The ASUS Chromebook Flip CX3 (CX3400) was a premium 2-in-1 convertible Chromebook released in 2022, featuring a 360-degree hinge that allows it to transform between laptop, tent, stand, and tablet modes. What set this device apart was its completely fanless design combined with powerful 11th-generation Intel Tiger Lake processors, offering silent operation for noise-sensitive environments like libraries, offices, and meeting rooms. The CX3400 includes a garaged USI stylus, making it particularly appealing for note-takers and creative users who need pen input. While this model has been discontinued and replaced by the newer ASUS Chromebook Plus CX34, it remains a capable device for those who can find one on the secondary market.

Detailed Insights into the ASUS Chromebook Flip CX3

The ASUS Chromebook Flip CX3 features a sturdy build quality that meets MIL-STD 810H military durability standards, meaning it has been tested to withstand drops, vibration, and temperature extremes. Despite using a plastic chassis rather than aluminum, reviewers noted the construction feels solid and confidence-inspiring. The “AI Blue” color option gives it a distinctive look that stands out from the typical silver and gray Chromebooks on the market. The 360-degree ErgoLift hinge is well-engineered, providing firm resistance at any angle while allowing smooth transitions between modes. At 3.64 pounds, it’s not the lightest 14-inch Chromebook available, but the weight is distributed well and doesn’t feel cumbersome during extended use.

The 14-inch Full HD touchscreen display delivers good color reproduction for a Chromebook in this price range, though its 250-nit brightness is a significant limitation that multiple reviewers called out. Android Police described the device as “useless outdoors” due to the dim, reflective screen, making this strictly an indoor Chromebook. The 16:9 aspect ratio is well-suited for media consumption and game streaming services like GeForce Now and Xbox Cloud Gaming. The display supports USI stylus input with the included garaged pen, which charges wirelessly when stored in its slot on the right side of the device. However, About Chromebooks noted that the stylus tip creates an “intolerable sensation” on the glass screen compared to higher-end styluses with soft tips.

The fanless thermal design is both the CX3400’s greatest strength and its most controversial aspect. While it delivers completely silent operation, the passive cooling severely limits processor performance. About Chromebooks conducted extensive testing and found that the Core i7-1160G7 processor mostly ran between 1.0-1.2 GHz during sustained workloads, never approaching its rated 4.4 GHz turbo speed. In benchmark testing, the Core i7 model actually scored lower than cheaper Chromebooks with Core i3 and even Pentium processors that have active cooling. If you need maximum performance, a fanless design is the wrong choice; if you need absolute silence, few Chromebooks can match it. The 50 Wh battery delivers genuine all-day runtime, with reviewers consistently measuring 8-9.5 hours of real-world use despite the claimed 11 hours.

Reviewer Insights on the ASUS Chromebook Flip CX3

C4ETech’s Perspective

C4ETech praised the ASUS Chromebook Flip CX3 as a premium convertible that delivers versatility through its 360-degree hinge. In his comprehensive video review, he highlighted the fanless design as a major advantage: “Asus have gone with a fan-less thermal design, so this Chromebook, it’s super silent.” He was impressed by the military-grade durability certification and the included garaged USI stylus, noting that “what’s new here? The CX3, given it has a full laptop form factor, it includes way more I/O” compared to tablet-style Chromebooks. He concluded that the CX3 offers a solid media experience thanks to the 14-inch Full HD IPS panel and comprehensive port selection.

Android Police’s Perspective

Android Police delivered a mixed review, awarding the CX3400 a 7.5/10 score while describing it as “the minivan of Chromebooks—a utilitarian device that might not be sexy, but it sure can get work done.” Their testing of the Core i7 model found that “apps always felt snappy” despite the thermal constraints, but the 250-nit screen brightness was a dealbreaker for outdoor use. They praised the large, responsive trackpad and dual USB-C charging ports that support 45W power delivery on both sides. However, they criticized the included stylus for its rough plastic tip and noted that the silver keyboard has poor legibility, which is made worse rather than better by the backlight. At $979 for the Core i7 model, they felt the plastic construction was inconsistent with the premium price.

About Chromebooks’ Perspective

About Chromebooks published the most critical review, ultimately recommending against purchasing the CX3400 at its original $979 price point. Their detailed stress testing revealed the fundamental problem with the fanless Core i7: “This is nearly a $1,000 Chromebook with an 11th-generation Intel Core i7…So why doesn’t the performance reflect that? Because there’s no fan, you get a silent experience. So yay! However, this processor is limited in terms of how long it can run at a higher clock speed, due to heat.” Benchmark scores showed the device underperforming not just cheaper Core i3 Chromebooks, but even some Pentium models. Kevin C. Tofel concluded: “Unless you fully understand the performance shortcomings of this particular Core i7 and really want a fanless Chromebook experience, I’d pass—at least at this price.”

Customer Reviews of the ASUS Chromebook Flip CX3

Amazon customer reviews paint a nuanced picture of the ASUS Chromebook Flip CX3, with the device averaging 3.4-4.0 stars across its three configurations. Customers who value silent operation consistently praise the fanless design, with one reviewer noting they specifically chose this model for use in a shared office where fan noise would be disruptive. The convertible form factor and included stylus receive positive mentions from students and professionals who use the device for note-taking in meetings and classes.

However, several customers echo the professional reviewers’ concerns about performance expectations versus reality. Those who purchased the Core i7 model expecting flagship-level performance report disappointment when comparing speeds to their previous laptops. The screen brightness limitation also appears in customer feedback, with multiple reviewers mentioning difficulty using the device near windows or in well-lit rooms. Build quality opinions are split—some customers find the plastic construction acceptable for the price, while others expected something more premium given the retail pricing.

The most satisfied customers appear to be those who purchased the mid-range Core i5 model (v3) at a lower price point, which offers a better balance of features and realistic performance expectations. Customers also appreciate the generous port selection, particularly the dual USB-A and dual USB-C configuration that eliminates the need for dongles and adapters in most situations.

Who Should Consider the ASUS Chromebook Flip CX3?

The ASUS Chromebook Flip CX3 (CX3400) is best suited for users who prioritize silent operation above raw performance. If you work in quiet environments like libraries, shared offices, or recording studios where you might be doing music production on a Chromebook, the completely fanless design delivers a truly noise-free experience that few other laptops can match. The convertible design and included stylus make it appealing for students and professionals who take handwritten notes or annotate documents, though those who want the best stylus experience should budget for a third-party USI pen with a soft tip.

This Chromebook is not recommended for users who need maximum performance, work outdoors frequently, or expect Core i7 speeds to match their desktop or high-performance laptop experience. The thermal throttling inherent to fanless designs means you’re trading performance for silence, and the 250-nit display makes outdoor use impractical. Users seeking a current Chromebook with similar features should consider the ASUS Chromebook Plus CX34, which offers 12th-generation Intel processors and Chromebook Plus AI features at a more accessible price point.
