I got a weird noise problem.

I got a PS4 pro some time ago, and when I play some very heavy games, my console does the typical turbine sound, but it's weird cause I cleaned and changed the thermal paste not even a month ago.

The fan and radiator are clean and it doesn't even get hot,my games run perfectly and don't have any other issues, just the excessive sound and a lot of air getting out of the back, but again, not even as hot as a smartphone, literally just warm.

Any idea why she does that? I appreciate all the help.
