What thermal pad size should I use for a Gigabyte GTX1080 G1 gaming?

[Master]

Hello everyone,
I tried reapplying new thermal paste on my 5 year old GTX1080 card. I used deep cool's z5 I guess. but the temps went up instead of down! like 10 degrees! and I had to crank up fans to keep it cool!
I'm not using that system anymore, my nephew uses it to play games, so I really didnt pay much attention until recently I noticed its got worse and I'd better do something about it.
I guess this is because of the torn apart thermal pads on the card (when I opened it, they were completely dried out and a good chunk of some them just tore apart) I put back what was remaining and you know the rest.
I looked for some thermal pads, but it seems they have different thickness, like 1mm, 1.5mm, 2mm, 3mms and etc
I'm not sure which one is suitable for this card.
also what thermal pad should I be buying? would anything suffice for the card, or should I go for a decent one if so what do you suggest?
also how much thermal pad do I need for this?
Thanks a lot in advance.

ekwb is a pretty good source for information like that thanks to their installation guides, which they have for all their waterblocks. And they also contain thermalpad information.

In this case they use 0.5mm and 1mm so chances are those will do fine. And that seems to correspond to other answers to the same question I seen online for this card, and most also point towards ekwb's installation guide for that kind of information in general.

I doubt the temperature went up because of the pads.

Thanks a lot really appreciate your kind help. will look into it asap

I'm pretty sure I used enough paste on the die and didnt miss anything! maybe I messed up on reassembling though, but not sure. anyway, I'll be reopening it again for changing the thermal pads, so I reapply the paste. is there anything I should be knowing concerning applying paste on the GPUs? is that really any different than the CPU?

Not practically. I'd clean the cooler (both the fans and the heatsink) as well from dust and other crap.

You just have to make sure the entire die is covered and that there is equal pressure from the heatsink, when you take it apart it should be obvious if all of the die was covered or if all of it was in contact with the heatsink.

Use feeler gauges

This is why my signature exists

Im running an MSI 1080 and havent removed the cooler. It still runs as it did on day one...

Hi,
I just use arctic pads
Cheap enough to get large sheets of all sizes.

Thanks a lot man, really appreciate it

Heres an update:
as someof you pointed out, it wasnt really about the pads, but the paste! I removed the crappy z5 and instead used an arctic silver 5 or something like that and saw a sharp change in temps, at least 7/10 degrees decreased and it stayed that way while previously it would ismply go up as you played a game like GOW at max settings.
I guess either that paste was fake or expired (if thats even a thing!)

2021 thread back from the dead! (in a good way)

Pads can cause issues if they're too thick, since they push the heatsink away from the GPU die - damaged ones can cause this as well, although it's not likely unless you smooshed them back in really badly

You can get cheap crappy pastes, expired pastes (they usually need stirring, which can be tricky in a tiny tube) and even fakes.
Heck, even some premium brands release bad batches or even bad thermal pastes (MX4 is super popular and has fakes online, and their MX5 replacement is already EOL - it wasn't a good product)

Same for the R9 290 I have.
