My Mac is running hot with the fan cutting in often. How can I diagnose what's wrong?
PS: Some sources mentioned Activity Monitor as a tool to diagnose this, but I couldn't find the application.

Best Answer
As IconDaemon mentioned in their comment, Activity Monitor is by default located in Macintosh HD > Applications > Utilities.
However, since your question seems to really be about your Mac running hot with the fan cutting in often, and since you say you're not proficient with Mac OS - any pointers welcomed, I thought I'd suggest you try starting in Safe Mode and potentially also resetting the System Management Controller (SMC).
Boot into Safe Mode
As a troubleshooting step you can boot your Mac into Safe Mode to see if your issue persists, both during Safe Mode and afterwards when booted normally again. Follow these steps to boot your Mac into Safe Mode:
Once you've booted into Safe Mode, let me know how you went. However, if the issue persists (especially if it persisted during Safe Mode) you can reset the SMC to see if that resolves the issue.
Reset the SMC
Your computer's System Management Controller (SMC) is responsible for a wide range of functions, including your Mac's cooling fans, power management, battery performance, and the list goes on. The instructions for resetting your SMC depend on whether your device runs
Since you don't actually specify your model of Mac, I will provide the steps for all three scenarios. Ensure you select the one that applies to you!
For MacBook Pros, MacBook Airs, and MacBooks where you can’t remove the battery on your own (i.e. it's a built-in battery), here’s what you do:
For MacBook Pros, MacBooks etc that you can remove the battery from, here’s what you do:
For iMacs, Mac Pros, Mac Minis, etc that only run from a power point in the wall
Once you've used the appropriate steps to reset the SMC for your model, report back on how you went.
Intel Mac temperature database
As an aside, you may be interested in the Intel Mac Temperature Database. This will give you an indication of the typical temperature ranges experienced by users of various intel Macs. The list can be filtered to suit your needs.
