Can you tell the the steps you took to get your heatsink replaced by a tech? I didn't get premium support but I'm pretty sure if my heatsink is faulty it's covered under the limited warranty
open the supportassist app from dell and click on get support, you will see the contact options give them a call and choose tech support, they are going to ask you for your express service code it will be right there under the number you dialed, the tech is going to ask you to reboot your laptop and press F12 several time to get to the boot option list and select diagnostic (I'm pretty sure the diagnostic tool will tell you that all pass) the you will reboot open the supportassist again and he will connect remotely to you pc to run some stress test if is overheating he is going to create a dispatch order to replace your heat sink and fans.
by the way I was playing battlefield V and is overheating again, I limited the frame rate to 60 and the temperature is good soooo there is no point to get the 144hz screen if the laptop can't go over 60 frames without overheating.
In a recent youtube review, Matthew Moniz talks about the keyboard heating up to 60 Celsius, which is too much for your fingers to take.
Have you experience anything like this under heavy load?
The cpu on my m15 idles at over 50c and immediately jumps to 100c when any program runs. I'm thinking of returning it.
don't think, Do it! I returned mine today.
I'm pretty sure they will try to charge me the 15% restock fee, but I have my previous service request that states the laptop was overheating. so I recommend you to request for service before return it.
this is a sad day for me, I was very excited with my first alienware.
It was doing very well for a couple days, then I play battlefield V and started to overheat again and after that was overheating for any single thing like before and my battery life went down to 1.5 hr just web browsing.
so I just got tired
