HP Envy 16 CPU temps too high

[Hadrian2]

My HP Envy 16 laptop's CPU temperatures frequently run extremely hot, even when doing basic tasks like simply browsing the web.   The CPU temperatures will hit 80+ degrees Celsius, and jumps to 90+ degrees Celsius running basic games like Crusader Kings 2.  Numerous other owners have posted similar problems with heat management, but haven't had many responses.  Has anyone had any luck troubleshooting this or getting a proper response from HP?   In particular, has anyone tried a thermal repaste?

Hi all - I tried a repaste of my GPU and CPU to see if this would help, as my online research showed that this could be a good option.  Unfortunately, it did not reduce my temps at all.  However, I think I've found the issue: the heat sink has likely failed on my laptop.  This is because the fans seem to be working, but there is no hot air being blown out of the laptop.  I'm going to try to replace the heat sink and see what happens.  One thing is for sure: this whole episode has soured me on HP and I doubt I'll ever buy one of their products again.

Hi all - good news.  As I suspected, the heat sink has failed on the computer.  I just replaced the heat sink on the laptop, and the temperatures are back to normal.  Of course, the heat sink conveniently failed just after the warranty period ended, but at least my computer is running again at normal temperatures.  I hope this information is helpful for other Envy 16 owners out there.  

Unfortunately, HP support was totally useless to diagnose this.  They also claimed 60 degrees Celsius could be considered normal operating temperature for my Envy 16 with a low workload, but that's nonsense.  Now that I've swapped out the heat sink, the CPU runs in the 40s on a regular basis, not the 60s.  If your computer is still under warranty, make sure you push for HP to service your laptop if that's the case.
