Surface Pro 7 Overheating when charging

So I've purchased and exchanged 3 brand new surface pro 7s in the last 20 days from best buy because of this issue. Everytime I plugged in the charger, within 5 mins, the backside of the Surface pro 7 starts overheating to an uncomfortable temperature. This was the case for the last 2 Surface Pro 7s as well. Their respective lot number was 1945 and 1943. I'm beginning to wonder if this is an issue with this particular batch ... Is there any answers for this?

    This worked for me... Not ideal though, a 10% drop in processor power... But, the fan has stopped now...

    45C is the target temp by design.

    Just tested it. It helps but is not the solution. CPU load is then at 9-30%, temperature between 40-45°C and clock speed at around 1.3GHz with Outlook, some browser tabs and some low load applications open. Not bad but even though the fan is a lot more quiet, it is still running and it's still more quiet without the charger connected

    A good workaround has been to go into power settings and reduce the power setting to 90% under the Processor Power Management setting for both on battery and plugged in

    Thanks for this advice, will try that and tell the results
