MacBook A1398 2015 Loud Fan

Hello

I have an A1398 2015 MacBook Pro 15" that has the right fan turning at high speed and making a lot of noise. I have cleaned it, removed the heat sink and replaced the thermal grease, replaced both fans but the noise is still present. Does anybody have any advice? The problem is not related to the hard drive as I have swapped it out but still have the same problem. Apple Diagnostics reference code PPF004 and PPF003. Thanks for your help.

check the fan itself, if you can try and replace it to see if it resolves the issue

The fans have already been cleaned with no success and then replaced with new fans. The problem remains the same.
