Cuh1115 ps4 no display

I have a ps4 that had a bad psu so I replaced it now when I plug the power cord in the system turns on automatically with solid blue lights followed by 3 beeps kinda like the eject button beep when there is no disc. Also the cpu fans are not turning on and when I removed the fans and placed my finger on the cpu when powered on it produces no heat. The mobo looks good visually any ideas possible reball?
