Along with all of the things others have said, you also need to make sure you have a proper cooling setup. Server class cards almost never have fans because they are expecting the server to pull or push air across the heatsinks. A typical PC case will not provide proper airflow to a card that’s expecting a cool room and server class fan CFMs flowing across it.

Edit: There are often workstation SKUs of GPUs that include a fan. I’m not sure about the p100 though
