Is there a difference between the Nidec fans for the Pro? Specifically g95c12ms1aj-56j14 VS g95c12ms1cj-56j14

They should work the exact same. Also, I wouldn’t recommend using thermal grizzly kryonaut. It works really well for about 6 months then my ps4 started getting louder than the console was with all the dust and stock paste/pads
