- Brand:
- ASUS

- 13+ years

The verdict
The Zenbook 14 OLED is a genuinely good value pick for anyone who wants a bright, sharp OLED display in a light chassis for everyday use — just don't expect it to handle sustained demanding workloads quietly, since the thermal and acoustic trade-offs show up quickly under real pressure.
Pros
- 2.8K OLED display with a 120Hz refresh rate is a rare and welcome combination at this price point
- Genuinely lightweight chassis, thinner and lighter than its predecessor without sacrificing screen quality
- Long light-load battery life makes it a solid daily-carry laptop for browsing and office work
- Starting price around $1,399 undercuts many rivals offering a similar OLED panel and processor tier
Cons
- CPU throttles noticeably under sustained heavy workloads, so burst performance is stronger than sustained performance
- Fan noise and audible coil whine under load are a recurring complaint in independent reviews
- RAM is soldered and non-upgradeable, so buyers must choose the right configuration at purchase
- Keyboard feel is described by some reviewers as mushy compared to competitors in the same price bracket
This review reflects ASUS's published specifications for the Zenbook 14 OLED UX3405 and the consistent findings across independent hands-on reviews since its release, focused on how it performs for everyday productivity versus sustained demanding work.
A standout display for the price
The 2.8K OLED panel with 120Hz refresh is genuinely uncommon at this price tier, offering deep contrast and smooth scrolling that competitors often reserve for pricier models. Combined with a lighter chassis than the previous generation, it's an easy laptop to carry around all day.
Where the compromises show up
Independent testing consistently finds that sustained CPU-heavy tasks trigger throttling, and the fans get audibly loud — some reviewers also note a coil whine under load, which can be distracting in quiet environments. This is a laptop built more for bursty everyday tasks than long render or compile sessions.
Who it's for
Best for students and professionals who want a bright, sharp OLED screen for browsing, office work, and media in a light, affordable package. Skip it if you regularly run sustained CPU-intensive workloads or work in noise-sensitive environments — the fan behavior under load will be a real annoyance.
Frequently asked
- Does the Zenbook 14 OLED throttle under heavy use?
- Yes, independent reviews note the CPU throttles during sustained demanding workloads, so it performs best on bursty everyday tasks rather than prolonged rendering or compiling.
- Is the fan noise on the Zenbook 14 OLED noticeable?
- Reviewers report the fans get audibly loud under load, and some units exhibit coil whine, which is worth testing in person or checking return policies for if noise sensitivity matters to you.
- Can the RAM be upgraded later on the Zenbook 14 OLED?
- No — the memory is soldered to the motherboard, so you need to select your desired RAM configuration at the time of purchase.
- Is the ASUS Zenbook 14 OLED (UX3405) worth buying?
- Yes, for buyers prioritizing display quality and portability for everyday computing at a competitive price. It's less suited to anyone who regularly needs sustained peak performance or works in a quiet environment.
