Thermal Pads for 7870 GPU

The GPU is MSI Twin Frozr III

I want to replace the thermal pads due to they have a lot of dust on them which is causing problems with heat

I'm just lost on thermal pad thickness any help

If I understand you correctly your heat dissipate sinks under the fans are dirty (dusty). They can be cleaned without removing them with a brush and a can of air. Just remove the video card to do the cleaning.

Everything else is fine but the thermal pads that are on IC Memory & VRM are dirty there is crap on them

what matters is the surface between the pad and the memory/VRM and the surface between the pad and the heat sink. The sides aren't relevant for heat dissipation.

I washed with water a lot of gum-like thermal pads to "regenerate" them and they worked fine afterwards, but I cannot guarantee that it will work for you too. Can you post some pics?

That's the problem thickness of the pads

Does your thermal pads looking a bit like the attached pic?

If so, check the thickness and measure size, just with a meter.

You can find different size of thickness, 0,5mm, 1mm & 1,5mm.

I'll go for 1mm thick and those pads are soft and could not hurt when pressed on the Vram's. And i'll not use sided adhesive pads, just the common ones

Please note: This thermal pad can be compressed to half of its original height!

1) There seems to be set of 2 or 4 thermal pads, sized 120mm x 20mm that you could use scissors to cut the right size for you, if needed.

2)There 's 5W/mk type or 7W/mk type, and seems the 5W/mk is the most common.

Here's a LINK

That's the layout of mine

Don't think I will apply conductive thermal on that

I've by the way replace the thermal paste of the graphics card processor a little after bought mine but it is not a good idea for the Vram's!

Those ready thermal pads are OK...i've bought some for my motherboard mosfets...they do the job well.
