My laptop is heating up too much

[ashohakan]

Overheating issues with HP 245 G7—even with a stand. I recently bought a laptop stand to help with thermals, but the temperatures are still concerningly high. Does anyone have advice on internal cleaning or settings tweaks for this specific model?

You should do cleaning and repasting properly. Check below video, it shows how to open your laptop and disconnect some parts which should be needed when cleaning. Use it. For cleaning, remove heatsink then unscrew it to access fans fully. Clean fans, air vents from both sides properly and secure it's screw again. Then apply good quality thermal paste like Arctic MX-6 on CPU/GPU chip (if have one) then apply heatsink and secure your laptops screws and parts.  (Make sure not to damage anything, don't do if you can't)

Below i attact the cleaning and repasting suggestion that is shared with gaming laptops. But cleaning and repasting methods remains same you can check this too:

Here are steps to do it properly (Taken from another user reddit guide):

Cleaning and repasting the CPU and GPU with PTM7950 or Arctic MX-6 can effectively improving heat transfer and airflow.

I’ll explain this only in short. Before opening your laptop, do your own research on what tools and materials are required and what important precautions need to be taken. Watch disassembly YouTube for your laptop (or a similar HP model) to understand the process. Prepare all necessary items in advance, such as basic tools, PTM7950, Thermal paste, thermal putty (to replace worn thermal pads/putty on VRMs if needed), Cleaning supplies, etc. Again, Do your own research and proceed carefully and at your own risk.

Once opened, disconnect the battery, remove the heatsink assembly, and clean the fans and air vents from both the inside and outside. I don’t have an official video for this exact model, but the video linked below shows what needs to be done. Your heatsink design may differ, but the process is the same: detach it, open it, and clean the fans and vents as demonstrated.

After cleaning, reassemble the heatsink. If the original thermal pads or putty on VRMs are worn or dry, apply new good quality thermal putty first like Thermal Grizzly TG Putty, UPSIREN UX PRO Ultra, Upsiren U6 Pro, etc in place of old thermal pads, or putty.. Then apply PTM7950 on the CPU and GPU (or thermal paste if you not using PTM7950). Use the video guide linked below, follow the thermal putty section if required, otherwise skip ahead and follow the PTM7950 application method.

(For users who are not using PTM7950, Use X method to apply thermal paste properly. Youtube videos on this topic also available)

After completing, apply heatsink carefully, connect battery cable and attach back panel of your laptop.
