Bad news: I opened up my GTX 1070 FTW DT to check for these gaps and
yes there were gaps on virtually all VRAM pads. Only 2 pads were touching the VRAM chips and only by a little bit of the corner. You can tell how it looks like if there was actual contact by looking at the thin thermal pad on one of the pictures.
Good news: I didn't wait for thermal pads from EVGA for the VRMs or VRAM etc and got my own (Fujipoly / mod/smart Ultra Extreme XR-m Thermal Pad 17 w/mk 100 x 15 x 1.5mm) and cut them up to 15x12mm portions. After putting them on my VRAM (the dots on them are from where I pushed them to make them stick to the vram) and placing the original 1mm VRAM pads onto the VRMs (there are enough to cover the VRMs) I put everything back together. I used Noctua thermal paste on the GPU.
MY TEMPERATURES DROPPED 10-12C. I used to idle at 43-45C and playing Battlefield 1 would get me to about 63-65C (using Precision X). Now my idle temperature is 30C and Battlefield 1 temperature is 45-54C. I doubt the Noctua thermal paste explains the huge difference because the original paste looked like it was good paste with good spread. I think the
VRAM thermal pad gaps were causing heat from the VRAM chips to soak into the GPU. I'm still missing the thermal pad for the backplate but I feel so much more at ease knowing that the VRAM is being cooled now and the GPU is operating closer to the temperature range it should be at.
Other news: Got the powerlink in the mail today! Woot! Thanks EVGA! Just hurry it up with the thermal pads, etc please so I can get back to overclocking my card!
