I would like to repaste by quadro 4000 but I can’t find any info for pad thickness. This is a plain 4000 not RTX 4000 or any variant that starts with a letter. https://www.techpowerup.com/gpu-specs/qu…
This may not be helpful and I am sorry. I buy multi packs of thermal pads ranging from. 0.5mm, 1.0mm, 1.5mm. as these are most common. I would say it would be either a 1 or 1.5mm thermal pad. I suppose it’s narrowed it down a little. If you build it with a 1.0mm and it’s over heating and crashing try the 1.5mm as the 0.5mm can make a difference in helping the pads make contact. I just use trial and error for work like this.
