Notebook Hardware and Upgrade Questions

Hi Everyone,

I own a HP Pavilion Laptop PC 14-dv0000 (190U5AV) which is running pretty smoothly under Windows 10 (22H2).

Since the last few days, it started heating pretty intensely (79°C / 175 °F), without reason (no recent Windows / dirvers / softwares updates nor new hardware connected). And it's staying pretty hot despite the fan is working (earing it blow). Well, yes, there is some cyclic cooling occurring, lowering to 50 °C / 122 °F... but unfortunately it's only for 10-20 minutes before the temperature raises again. 

The hot zone is located on the right half of the laptop. The whole right half. And Speaking about heat is at the point it become very inconient to put your hand on this zone. Not to say I am coding and spending lot of time on it... 

Processor is an Intel Core i7-1165G7 @ 2.80GHz. Config with 16 GB RAM, 1TB SSD and dual graphics cards (Intel Iris Xe + nVidia GeForce MX450).

Drivers are all up to date. Same for BIOS, latest release.

I am always using some pretty common programs (code editors, graphic editors, browsers, etc.), and no gaming on this PC. So really nothing special.

I opened the bottom lid in order to spray some compressed air.

The inside parts, the heat sink, the heat fan and the ventilator weren't very dirty at all (only a very small dose of dust). And the ventilator is working. 

I even raised the laptop with some little pads, to let more air pass underneath. No success. 

Last but not least, I ran the "HP PC Hardware Diagnostics Windows 2.2.0.0" : Success on all tests. Great, but not great 🙂

So, before I'm starting to fry some breakfast eggs on it... does anyone have a great idea of what is going on with this laptop?

Thanks for reading and for your eventual ideas / collaboration.
