My Macbook fans running really high even when everything is off. I don't have high end applications running, I'm not playing games, or rendering stuff. I also have tried resetting the SMC.
Here's some information about my mac.
And here's the fan speed.
And note that I primarily have google chrome running in doc, with only 3 tabs when I took that screenshot.
MacBook Pro 15″, macOS 10.15
There are few workarounds for this.
1, close the MBP LID and work only on external monitor
2, find a “compatible” monitor. Its related to the monitor refresh rate and resolution combination. Some monitors works just fine and some need little tweaking with the refresh frequency by help of 3rd party app.
there is a huge topic on macrumors forums where ppls are discussing the monitor types and details.

If you have connected external monitor, that may be the issue. The radeon 5300/5500 cards are famous for this design issue, where the Radeon highs side is taking around 20w power for no reason...just google that issue
I closed the lid, but it still is not dropping as low as it does without the external monitor.
However, I'll research more about it, really weird. Such an expensive machine, and can't run external monitors properly.
See what's running your CPU hard. Perhaps it's Chrome (or a related helper), perhaps a background process.
Yup, it's the external monitor. I removed it and the fans went down considerably (almost 50%) Is there a way to fix that? or do we just have to bare with it?
