Thermal pad thickness

I took my Zotac 1070ti amp extreme apart to deep clean and replace the thermal paste however when I disassembled the card I noticed something. Two of the memory chips are missing pads and the other pads just seem like the person who put them on had a bad day lol. As an American I have no easy way to measure in mm :upside_down_face: I’ve searched for a tear down guide/specs with no luck. I def hoped that iFixit had something but no dice, so at the end of the day if anyone has info about the thickness of the pads that’d be the bees knees. I’ve attached pics of the board/cooler the “top” chips are the ones in question.


honestly, a set of calipers are fairly cheap on amazon. and a good tool to have.

i would buy a set and then you just need to gently pull the pad off and measure the uncrushed portion.

Well
looks like cheesy assembly line effort.

(for reference a dime is about 1mm in thickness)

visually speaking:
go to amazon get the Gelid ultimate pads, 15w in transfer, get 3mm thickness

apply (using exacto knife, a pad the same shape per chip, if you don’t feel good enough to be that precise then apply a strip to cover each side making sure you cover each chip

using a hair drier heat up metal heatsink and warm up the pads on the pcb, then immediately after
screw together carefully and evenly alternating half turns on each screw until fully seated

the heat helps the pads soften to shape making forming and adhesion better.

Gelid ultimate 3mm

you can have them by tomorrow

if you can visually see that its no more than 2 dimes thick in distance, then consider the 2mm pads, but for those you must have no more than 1.5mm of travel or the 2mm pads won’t make enough contact

Well using the dime as a reference (which I didn’t know and will keep in my back back pocket) the pads are about 2 cunt hairs taller. My initial thought was a 1mm pad would be fine but my gut says go with the 1.5 pads.

go bigger and squish that shit
the delta naught of air is almost 0
so better more than less

I agree, a 6-inch digital caliper is around $20 and a 12-inch $40.

I just ordered a 12-inch with stacking coupons for just under $30 because I need one for my 3D prints.

Too thick degrades contact with the GPU die, though, so getting the right combination of 0.5 mm steps and compressions is helpful.

Putty may be a better option, though it appears some GPUs might take the bow from pad forces into account. So switching to putty may also reduce contact quality.

Don’t have one in my small town and it’s not worth dealing with maniac drivers to go “into the city”
