Question regarding rubbery thermal pad in dv6575ca notebook

Hey again!

I just finished taking apart the dv6575ca to apply new thermal paste on the gpu and cpu.

When i had it apart, i found that there was also a spot on the heatpipe/sink for a 3rd part which i believe to be the north/south bridge? The GPU and CPU's themal paste needed replacing, so i replaced with arctic silver thermal paste.

However this 3rd part was only using a rubbery pad. I have never seen a rubbery thermal pad before but with a bit of googling i found it. I could not use thermal paste instead of the pad because the pad had quite a bit of width that was filling in a gap(if i used thermal paste it would not reach the heat sink). I was not thinking and got thermal paste all over the pad. I used rubbing alcohol to clean the rubbery pad as best as possible but i am worried that the pad will not work properly now? i have the laptop running and in hardware monitor, the GPU and CPU temps are great but i do not think i can see the temp for that 3rd part. Any thoughts on if that "rubbery thermal pad" will do its job still? or should i replace it asap?

Thanks,

You could always replace those with copper shims if you can find them.
Usually, copper shims are sold in different thickness and are used to shim big electric motors/pumps so they don't vibrate.

But if you can get the right thickness of copper to replace the pads, and use thermal paste (just enough), well, you should get better results.
Thermal pads aren't great and they don't transfer heat much.

Hmm, GeForce 8400GS GPU. The thick rubbery pads can be replaced by a copper penny (pre-1983 American) or some other copper shim. That makes a HUGE difference in heat dissipation. The pads are terrible. Thin pads need... something else. There's a guy on eBay selling shims that work for cheap.

 

The rubbery pad was not being used for the gpu, the copper pipe/heatsink can touch the gpu and cpu. I think it was the north/south bridge that required a spacer in order to touch(the rubbery pad) the pipe/heatsink.

I have been monitoring temps and the cpu/gpu are fine. Also the THR1 in hardware monitor seems alrite(idle is 48-50) and the cpu is idle 42-45 and gpu is 48-50 idle.

I think i will just leave it. Taking this puppy apart takes a good couple hours.

Lucky for you then. Seems like yours was manufactured with a little more sense of reason.

When you do it first time, yes... I'm now able to take a dv9000 apart in 15 minutes and put it back together in 30.
