Question about Corsair iCUE 4000X

You can attach an NZXT Kraken 360mm AIO to the top of the case, as the case offers compatibility for radiators up to 280mm with Corsair LPX DRAM. However, it is important to note that the Kraken 360mm is larger than the recommended size. So it might not fit directly without adjustments or special mounting methods. It would be advisable to check the exact dimensions and mounting options to ensure that the AIO cooler can be installed correctly.
