Question about Corsair iCUE 4000X

The Corsair iCUE H100i Elite LCD XT AIO does not fit perfectly at the top of the case, as the case has space for a 240mm radiator in the top. The H100i Elite LCD XT is a 240mm AIO, but is usually mounted on the front or bottom for the best cooling performance. Top mounting could be problematic due to limited space and potential airflow interference. It is advisable to install the AIO at the front to achieve the best performance.
