is it safe to use tim (mx-4) on a 7970 memory chips instead of "thermal pads" because they are not available where i live - Page 4

post #31 of 38
In fact, does anyone with a 7970 know what thickness of thermal pad is required for the VRAM chips? I have an idea brewing. Also what length would be required? they seem to come in 120mmx20mm strips. I'm thinking 2 strips would be enough?

i don't think the gap is really all that big....

well the thermal pad comes in 0.5mm, 1mm, and 1.5mm thickness. Do you have access to a feeler gauge? Could you find out the gap size?

Some say .5 on the vram and 1mm on the vrm.

If you want a tighter fit then you can go 1mm on vram too

seems like the previous owner was not an honest person... no 7970s ship with tim on the VRAM and especially AMD reference 7970s.

I suggest fujipoly extreme if you can order these in your area or you can go ultra for a little bit more, the extremes hold up very well in maximal overclocks for my 560Ti, not sure how good ultra is, looks pricy though wink.gif
