According to Scan Computers (https://www.scan.co.uk/products/corsair-h115i-elite-capellix-rgb-aio-cooler-2x-140mm-ml140-rgb-pwm-fans-copper-heatsink), they're expecting stock of the cooler on the 4th November 2020, I'm not sure if that's the same as the Corsair release date though as they'll have shipping differences and stock allocation etc.
