RUBIK Pi 3 Issues

Hi! Could anyone please help me with following issues?

  1. I have attached Raspberry Pi’s cooling fan, it works just fine, but when I shut down Rubik Pi 3 (with android 13 installed) the fan just start spin turbo fast and keeps spinning (but Rubik Pi 3 is swithed off and power supply plugged in) until I disconnect the power supply. I don’t know much time exactly it spins becasue I always getting tired of waiting. Is there any kind of solution?
  2. I have 1 TB NVME disc installed, to make it work properly, the device formats it to FAT32 and detects it as an external USB drive.
    I know NVME can’t be bootable yet (and I pray it will be some day), but with FAT32 I can’t store any files larger than 4 GB (for example game roms, etc.). I tried formatting it to exFAT, NTFS, ext4, but the device doesn’t recognize it and keeps asking to format to FAT32.
    So, any way to make any other file system but FAT32 work? And any way to make NVME as a part (addition) to internal memory?
    I know on some devices (had this experience with Nvidia Shield TV) it’s possible to add external USB devices as an addition to internal storage to install apps, etc.
