QUAD SATA KIT for w/Raspberry PI 4 overheating

I’ve had it off for two weeks and the whole thing is really hot. Keep in mind it was off. The fan kept turning on. So I just shutdown the NAS. It’s fully configured except for WiFi which no matter the method I cannot get to work on Raspberry Pi OS Lite. Is this happening to anyone else. Again mine was off but hot like I was playing Oblivion on it.
