Hi! Can someone please confirm the thickness of blue, yellow and grey thermal pads used in this photo? Thanks! :)

Hi,
Get a verity pack or large sheets for future projects
Most common are 0.5 & 1.0 & 1.5mm
 
It looks at least 1,5mm to me. From my humble experience 0.5 is very thin and I haven't seen it used in GPU or laptop a lot. I would say get something thicker, it's easier to squash it, than having a microgap due to a very thin pad.

Thanks for sharing your experience. I think blue ones look like they are 1.5mm but hard to tell what yellow and grey ones are. My guess would be 1mm!

I would keep your suggestion in mind! Thanks!

Can I stack 0.5mm pads on each other and use them since I didn't buy 1mm ones? Will it work? Thanks!

you can stack them and yeah just buy 0.5 or 1 mm incase you need something since most use that
 
I would highly suggest making sure you use the right thickness pads. Do your research, make sure. You may think .5 mm isn’t enough to hurt anything, but just recently, I sold a rtx2070 fe. The person that bought it replaced the pads. He used 1.5 mm. 1 mm pads are what was suppose to be used. That .5 mm was enough to keep the heat sink from making contact with the GPU, causing almost instant overheating and crash.

some people think that when you tighten the heatsink, it will squeeze the thermal pad and it's fine. in some cases you gonna find bent pcb coz of it

I bought 0.5mm and 1.5mm of these ones: https://www.amazon.com/SOLUTIONS-GP...lid+Solutions+GP-Ultimate,aps,480&sr=8-4&th=1

Should I buy 1mm too or stacking 0.5mm will suffice? Thanks!

Agreed! That's why I'm really confused as to which is the correct thickness for these stock thermal pads! I don't want to mess it up! I need to be really sure!
 
Hi,
Yes get 1.0mm
It was said you could stack to get 1.5mm but personally I'd get all three sizes and be happy.

absolutely agree. Even 0.5 mm difference could be an issue.

I have no direct experience in that, but I'm not sure that stacking 2 x 0.5 mm would have the same thermal conduction of 1 piece 1 mm.

Thanks I bought all three thickness pads -> 0.5mm, 1.0mm & 1.5mm and a vernier caliper to measure stock pads thickness to be on the safe side! :)

Hey XT785! I know this is a super old thread but I also happen to have this same computer and had the same question about the thickness of each pad. Do you remember which pads you ended up using?
