Xiaomi is set to unveil the Redmi K90 Max later this month, as confirmed by President Lu Weibing on Weibo. This device may either be a rebranded version of the anticipated K90 Ultra or a completely new model. A standout feature of the K90 Max is its active cooling fan, which boasts a larger diameter than those found in competing smartphones. This fan can achieve an air intake volume of 0.42 cubic feet per minute (cfm), which is 30% more than rival devices. Remarkably, it can lower the device's temperature by 10 degrees Celsius in just 100 seconds on its highest setting, all while maintaining a noise level as low as 32 decibels. Additionally, the K90 Max will come with IP66/68/69 certification, ensuring it is resistant to dust and water. Interested customers in China can reserve the phone for a mere CNY 9.9 (approximately $1.44), which includes a mystery gift package valued at CNY 3,600 (around $523) upon the phone's launch. More details are expected to emerge in the coming days.
