Well as I can tell from fan noise levels on my current MBP - running a device simulator or a VM along with a IDE is sustained load for sure.

You may want to check the Activity Monitor to make sure the CPU is actually at 100% when you're doing that. Apparently it's quite easy to get the fans going on the Intel Macs even on lighter loads compared to the new M1 ones.
