MSI Heat Issue and Possible Solution [GE72MVR]

Hey everyone,

So, I have the GE72MVR and like many other MSI owners, this thing doesn't have total proper heat management without a noisy fan. After swapping out the mediocre factory paste that came with it with Noctua NH-T1, things got better. However, there is one nagging heat sink on this thing... the palmrest.

For the life of me, I don't understand why they used metal for the palmrest other than a flashy buzzword or "feature". The thing is a heat sink to my hands from whatever is warming up underneath the keyboard. There is something on the left side of the touchpad that gets pretty warm. It is enough that I have a fan blowing on me and the laptop on my desk at home. I like the cooler air, but I hate the fact that I need it to not sweat all over the palmrest and keyboard if I am playing a game, or shoot, just using it.

So, being an engineer of a sort, I've decided to tackle this issue. But, I like more input, so I am here asking for yours.

I've narrowed down to two types of material.
Leader OPUS LD8100 w/ 1W/m.k thermal conductivity:

Sil-Pad 400 w/ 0.9W/m.k thermal conductivity:

Both offer the thinness that I need and the best thermal insulation that I can find in a small package. While I don't know the exact electric conductivity properties though.

So, thoughts?

 

As for the solution, I will wish you the best of luck. As for WHAT causes it my guess is that the PCH chip might be in that place. Or you are feeling the heat of the m.2 ssd. To be fair, there should be a plastic plate insulating those from the palm part of the laptop. Maybe you can check in hwinfo or something whether those 2 are running very hot?

 

Left side of the touchpad, on most of them there's a drive right there. Are you planning to put this material inside the system or just pad the palm rest with it?

 

I haven't checked the temps over time to see what that is. It might be NVME. It's been a bit since I've had it taken apart. I was thinking on checking temps later on.

My plan was to take the SIL-PAD 400 and place it under the palmrest itself, that way it doesn't matter what was creating the heat.

 

Looks like it might be the HDD:

 

Actually, after further review using other videos, and know the HDD isn't on that side. HDD is on the right side of the palmrest which is a perfect temp. It appears to be the Northbridge chipset. It is just under the touchpad, offset to the left. There isn't anything cooling that chip!

I've ordered a few large 200mm x 200mm thermal pads and some Kapton tape. The idea is to attempt to block most of the heat getting to the palmrest, and instead redirect most of it through the thermal pads (which I plan on applying over the thermal tape and into areas that get airflow). Essentially, making a large heatsink with thermal pads that would help cool the chipset by directing heat to the airflow areas.

 

Hi, as an owner of ge72vr which motherboard is very similar to yours but my has gtx1060 while yours is 1070.

The hot spot(very hot sometimes) under trackpad is a PCH. The die of is upside The palmrest not downside like cpu or gpu and is heating balet The palmrest
Solution that works best was as following:
I bought gelid subzero heatsink for 2280 m2 ssd( around 3mm height), cuted 1/2 of it and used alphacool 1w/mK thermal dual side adhesive pad cuted into window shape and placed around the pch die while on the die I used a bit of phobya nanogrease Extreme 16W/mK. And placed The cuted heatsink on the die.
Thermal paste will transfer heat from pch to the heatsink while the adhesive pad will keep it in place.
It will help you spread the heat on a larger surface so in the end you will still feel palmrest a bit warm but no one very hot spot which in my opinion is good resault.

What you can also do is set in bios in system agent VR ac and dc domain 1 exactly same procedure as for cpu domain which will make some undervolting on The pch

 

Hey,

Thanks for posting.

Actually, I did try to spread the heat across a larger area with 6 W/mk thermal pads. The pads did their job but sent more heat to the palmrest. I didn't give enough surface area to cool it down via the fans.

I ended up not using any thermal pads, removed them all.

What I did do instead was create my own heat pipes!

First, I flattened an older copper heat pipe, used Noctua NT-H1 paste to connect the north bridge chipset to the flat copper, and Kapton tape to protect it all.

Second, I used the shiny side of heavy duty aluminum foil and made a thick pipe from under the keyboard, connecting the underside of the CPU and GPU.

Both pipes went to the fan.

The palmrest heat near the touchpad is nice!

The keyboard still gets warm, but by a good 25% less than before.
