By "lab" I am assuming you mean that you sent it into Dell Depot Repair service? If yes, you need reinitiate contact with Dell Support for your country and arrange for another repair service. So the technician will see it, tape a note to the laptop lid explaining the issue and what has already been done. Or you could disassemble it yourself and clean and apply new thermal paste. Here is the Service Manual.

Yes I did send it to the Dell Depot Repair service lab and I did contacted them as soon as I found the problem still exists, still waiting for the technician to contact me.

If I could resolve this problem myself I wouldn't bother sending it to the lab since it took them a week to work on the laptop last time.

I'm just trying to figure out if the problem is really the termal paste or it could be something else.

By the way I ran diagnostics and all tests pass.

Unknown. Did you have the same issues when using the Dell AMD driver versus the retail AMD driver?

Ok so I did it.

Still the same issue here, starting temp is 50C, after 2 minutes after performing a stress test the value is already at 98C.

Alright, thank you for that!
