Any body having, or hearing about overheating in the 27 inch iMac with the top of the line i9 CPU?

I have one.  It's flawless as a machine.  To judge by the ambient office temperature there's definitely heat coming from it, not that you'd know it from touching the machine or hearing anything run, in fact the fans have kicked in only once in the past six months and ran for about 5 seconds, it was doing some major calculations at that point.

Not heard of anyone having issues at all.

Do you mean the 8 core i9 with the highest clock rate?

Yes, the 8 core i9 with the highest rate. There are many reports of the top of the line MacBook Pro with the i9 heat throttling down. Admittedly, that's a tighter space than the iMac but I'm wondering it also an issue with the 27 inch iMac.

I have the i9 8 core in my 2019 MBP and thermals seem well managed.  The fans kick on during some workloads but I don't notice much throtling.   This is not a scientific answer though. 

I can't speak to the 27" iMac with the i9.

Apple throttles the power of the gpu and cpu if overheating might become an issue...
They did that with the iMac Pro.
I have a 10 core i9 in my desktop. it has a liquid cooler on top of the CPU that works well and is necessary.
Temperature may still go to some 100CÂș under heavy workload.
If i go to more cores i even need a complete liquid cooling system to run without limits.
