Heatsink mod HP m6 1035dx?

Hello, I was wondering if it's possible to use a dual heatpipe heatsink from HP to better cool my laptop? Sorry I'm new to the whole cooling mod, but after doing some research it seems that having multiple heatpipes linking to the fan results in better temps. I know for a matter of fact that the dual heatpipe heatsink would work for my laptop since HP has the same layout for other laptop models. My question; however, is whether or not I can cut off the copper heatplate (which is supposed to go over the dGPU) without damaging the heatsink itself.

Can you install it without removing the copper plate for the GPU?

 

There's no die in between the mobo and the heatsink. So if I were to put the heatsink without removing the copper plate, I'd be risking the copper plate making contact with the motherboard thus transferring the heat to the mobo and reducing its lifespan.

 

It's gonna be tricky to cut that plate off because it is welded to the heatpipes.

Edit: be careful with heatpipes. They actually contain fluids made up of different chemicals.

 

If it's designed to sit on the top of the gpu die and be held down by screws, I'd be surprised if it touched the motherboard while properly installed. If there were a dGPU there, don't you think that would be transferring heat to the motherboard anyway? From your photo, that area of the pcb looks unpopulated.

Doesn't matter anyways because there's nowhere to put the screws anyways. For comparison, here's the same motherboard but with the dGPU.
Notice that this one has screw-holes for all 3 screws to go into, whereas the previous one shown only has holes. Meaning that the copper plate would have to make direct contact with the mobo unless I cut off the copper heatplate.

 

A bolt cutter, hacksaw or angle grinder will get rid of it easily, copper being a rather soft metal and all. Just don't place the heatpipes within the vice and you'll be fine.

But really, why bother? Apply electrical tape all along the bottom of the gpu flange if you're worried. That'll insulate it completely from the motherboard. Besides; it's additional copper, so a 'sink' of heat as well, providing a small bonus. The motherboard won't care either way; its temperature is merely due to ambient heat inside the laptop.

 

I still fail to see the problem.

Looks like it will work fine. Just don't tighten the screws.

Thank you! I might not even need to worry about it touching the mobo since the screw-holes that are designed to go under the heat plate are elevated meaning that it wouldn't touch the mobo in the first place. Looks like I got worried for nothing
Anyways, thank you and thank everyone else that posted in this thread!

 

Yeah, my bad, turns out I don't need to worry about it at all.

 

to be honest, having the (relatively) heavy copper plate there, unsupported, is asking for some sort of twisting/lifting of the CPU heatsink plate when you move your laptop around. the tension screws on the CPU side aren't that strong.

Cut a small, thin layer of matching shape foam and place it underneath the unused GPU area, not too think that you have to significantly squish it down, just enough to keep it from bouncing around and attach it to the heatsink plate with some tape

 

Don't forget to let us know about the impact of new heatsink on cooling performance and CPU tepms, of course!
