Laptop overheating even after servicing

[nishant1695]

My laptop has been serviced recently (cleaned + thermal paste changed). But about 2 weeks back it started overheating with nothing running. There were some windows updates that were being downloaded i thought i could be because of them. I use a dual booted system and when i boot to linux, laptop performs just fine with no heating issues. I reinstalled windows yesterday to rule out any software conflicts and issues. But the laptop would still overheat. On consulting a tech support guy, he said that it could be my graphics chip failing. Could that be the case? How bad is it? how much is it going to cost me to get it repaired.

Specifications -
CPU - AMD A10-4600m
GPU - AMD Radeon 7660g+7660m

The heatpipe coolers fail on laptops all the time, to give you an idea of how often, my eight year collection weighed almost 800 pounds of mixed copper at the recyclers, only from heatpipe coolers with the aluminum removed where applicable.

It's not unusual. Cost is minimal. What's the model of laptop?

Model of the laptop is HP Pavilion g6-2312ax.

What exactly fails when the coolers fail in laptops?

The heatpipes are sealed with a slight vacuum in them, when that lets go it stops working correctly.
