It was a truly ridiculous idea to put an i9 in any laptop. That generation of i9 is difficult to cool even with liquid cooler systems in big ATX cases.
Just to remind, the mobile + desktop lines are not the same thing even if they both get the same branding.
The top end chip in the 2019 MBP was the i9-9980HK, which had a TDP of 45W.
Would have been reasonable in a chunkier workstation/gaming type of laptop with the kinds of cooling solutions those usually get, it's not something that needed an actual desktop liquid cooling solution to run well.
But obviously the 2019 MBP design/cooling was not up to that task.
