Xiaomi officially confirms the Redmi K90 Max, a gaming-focused flagship with an 18.1mm active cooling fan that reduces temperatures by 10°C in 100 seconds, plus shoulder buttons and 165Hz display.
Xiaomi is expanding its Redmi K90 lineup with a third model that's all about gaming performance. The company has officially confirmed the Redmi K90 Max, a flagship device designed specifically for mobile gamers who demand sustained performance without thermal throttling.

Built-in Cooling Fan Takes Center Stage
The most striking feature of the Redmi K90 Max is its integrated active cooling system. Xiaomi President Lu Weibing revealed that the device houses an 18.1mm fan with a vertical air intake design. This isn't just a gimmick – the company claims it delivers 1.3x greater airflow compared to other smartphones with cooling fans.

More importantly, Xiaomi says this cooling system can reduce the device's temperature by 10°C within just 100 seconds of sustained gaming. For competitive mobile gamers who play for hours, this kind of thermal management could mean the difference between maintaining peak performance and watching frame rates drop as the phone heats up.
Display and Performance Upgrades
The Redmi K90 Max will feature a 165Hz display, which is a significant upgrade over the 144Hz refresh rate found on competitors like the RedMagic 11 Pro (currently priced at $799 on Amazon). This higher refresh rate should provide smoother gameplay and more responsive touch controls – crucial advantages in fast-paced mobile games.

Xiaomi also revealed that the K90 Max will feature a dual-chip setup, though specific details haven't been disclosed yet. For context, the K90 Pro Max uses the Snapdragon 8 Elite Gen 5 chipset, so we can expect the K90 Max to be in the same performance tier, if not higher.
Gaming-Centric Design Features
Beyond the cooling system, Xiaomi is packing the K90 Max with features that cater specifically to mobile gamers:
- Shoulder buttons: Physical gaming triggers for more precise control during gameplay
- Touch control optimizations: Enhanced touch sampling rates and accuracy
- Network stability improvements: Better connectivity for online multiplayer gaming
- In-game audio enhancements: Optimized sound for competitive gaming scenarios

Launch Timeline and Market Positioning
The Redmi K90 Max is scheduled to launch in April in China. This timing positions it as a mid-year refresh in Xiaomi's gaming phone lineup, giving the company a chance to compete with other gaming-focused devices that typically launch in the first half of the year.
While Xiaomi hasn't announced international availability yet, the Redmi K90 series has historically expanded beyond China, so global gamers may get their hands on this cooling-equipped powerhouse soon.
How It Compares to the Competition
The gaming phone market has become increasingly competitive, with brands like RedMagic, ASUS ROG Phone, and Black Shark all offering devices with active cooling. Xiaomi's approach with the K90 Max appears to focus on maximizing cooling efficiency while maintaining a relatively slim profile with its 18.1mm fan.
The 165Hz display also gives it an edge over some competitors, though the actual gaming experience will depend on factors like touch latency, software optimization, and how well the cooling system maintains performance over extended gaming sessions.
For gamers who prioritize sustained performance over long gaming sessions, the Redmi K90 Max's combination of active cooling, high refresh rate display, and gaming-specific features makes it a compelling option in the increasingly crowded gaming phone segment.
