I have a 2018 Macbook pro and the fan is constantly running, really loudly. The only time it switches off is if you press siri. I have tried to do the SMC reset but still no joy. Can anyone help? Thanks in advance.
MacBook Pro 15″, macOS 10.15

If the Mac is on, the fans are on. They idle at ~1880 rpm the can ramp up to ~6000rpm under a heavy load and sounds like a jet plane.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus—
all these are known to causes issues
To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac
This will tell you if it a universal issue or isolated to your user/admin account.
If no insight or resolve— you can try running the user Diagnostic: ..not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code if there is a hard ware issue
Use Apple Diagnostics to test your Mac
