I've been getting several PS4's with a similar issue.
The stock paste they use is rubbish and any thermal paste you as an end user apply to it will definitely work better.
I have OG from a month after release and I swear it doesn’t make that much noise.
A bit off topic but I'm thinking doing this on my ps3. But expensive or cheap thermal paste does make significant difference?
6th year strong. Never cleaned. Cursed myself: probablyI clean the ps4 at least once a year, (dusting the insides) but never replaced the paste...

Just replaced my thermal paste on PS4, and now it runs silently, even on full load.
See example here of the noise comparison from before and after replacing the paste.
