Area above where the battery is is uncomfortably warm.

    Laptop is a P960ED.

    As the title states the area of the laptop on the left-hand side is uncomfortably warm. Of course the back where the power button is also extremely hot but that's kinda understandable as that's where the fan exhaust is.

    The area above the battery is ~35*C which I feel isn't normal as it wasn't previously like this when I got the laptop initially. I am running linux on it so I have disabled the Nvidia GPU and I've used intel's DTPF to set the TDP to 35W and undervolted it too to reduce overall heat. I don't remember the temps being that warm previously. Also the battery doesn't seem to have a thermal sensor builtin(for whatever reason) so I can't check that. I don't know what's causing this random increase in temps in that specific region for. Area towards the back is ~39*C

    Also has anyone put a PCH heatsink on their PCH chips. It acts like it's safe to just stick it on there but I'm kinda hesitant as I don't know if a single layer of 3310 thermal tape will be enough to stop it from shorting itself. I already put some thermal foam on it to stop it from reaching 90*C+ and now it's reading 60*C which is still warm for a chip that's doing essentially nothing. I feel like I can get it below 50*C with that heatsink.

    The sourhbridge is running the i/o so it's always doing something basically.

    i have same problem, but with different clevo laptop. In my case it is not battery but audio chipset - it's placed in same spot as battery so my first bet was battery also(probably 2xcapacitors overheating). I going to try some small radiators to fix issue. Mby in your case this kind of radiators could help.

    PS. What kind of foam did lower temperatures on PCH by 30C?

    Air is a terrible heat conductor so I'm guessing they mean thermal pad.

    I am just using some AS5 thermal padding because it was cheap and I wanted to see if it'd help at all. The thermal conductivity is extremely low but it's way better than air.

    I personally doubt it's the battery as it's not charging or dishcharging atm(I have flexicharge enabled). It may be the audio chipset then. My biggest issue is clearance the laptop is _extremely_ thin. Like the clearance between the PCH and the back chassis was only ~7-8mm.

    Has anyone ever put those PCH heatsinks on their PCH I, personally am extremely weary of putting aluminum or copper directly onto the chip.

    Edit: here's what I was going to use but chickened out as I don't know if it's safe to directly put aluminum ontop of the pch.

    I know that since they're coated the thermal transfer properties will be lower than uncoated copper but they were the only ones I found that were within the range of safety from my measurements.

    P.S. Is the audio chipset also above the battery on this model also? If so I'll probably put some foam on top of it.

    It's safe afaik. Coopper ones would be better.

    Idk. Couldn't find any service manual of your laptop. I guess u have to disassembly it to find out:)

    Anyway. My Ram heatsinks arrived so at Monday i will try it out on sound board and will let u know if it made any difference.

    UPDATE:

    So i installated extra cooling. Unfortunately it didn't help at all. Maybe it's even worse since copper without air flow is working as heat trap in this situation. I was trying extra old Realtek drivers. Nothing seems to work. It's hard to comprehend how even audio board is able to heat up to point when it starts to burn.

    I guess im out of ideas.
