iMac mid 2011 21.5, what is the gap for thermal pads on vram?
I got the dreaded stripes and tried the baking method and amazingly it worked. But it came back and I think it's because I used regular thermal paste on my vram instead of pads or thick paste.
I'm going to get the pads but looked everywhere and can't find if I need 1mm, 1.5mm, or 2mm.
Thanks!
Is dit een goede vraag?

**Update**
I got the K4 and K5 paste and redid the whole thing properly. Unfortunately I still have the stripes.
**Question**
I wonder if I actually zapped the gpu.
**What happened**
On that first attempt it worked fine and I only booted it up and observed but after a short while (less than 1 hour) the stripes came back. I know I didn't apply enough paste (which was confirmed when I took it out).
On my second attempt I re-baked it, applied the proper amount of K4 to gpu and K5 to vram and still got the stripes.
**Next Steps**
1) Buy a used card and try a third time (I assume the risk is that a used card is also fried).
2) Re-bake my card again
3) Take it to Apple and expect them to charge me hundreds which I'm unwilling to pay for a 2011. But maybe it'll be less.
Any wisdom y'all have is appreciated!
