Just a little thermal paste on back side of cpu

[AvadaK]

So I had to send my new motherboard back for rma stuff, and when cleaning the thermal paste out of my i7 6700k some of that stuff got in the back side (no idea how), very thin line and it affected about 5 pin slots or whatever they are called when there are no pins nowadays. I got most of it out, when you look straight at them you can see very thin layer of greyish there, so is that bad?
I cleaned the cpu with these paper coffee things, I don't have that 90% alcohol at the moment.

Best bet is to go to the dollar store (or some cheap equivalent) and pick up some make-up removal triangles (at least that's the shape of the ones that I have used). They are a foam material that does a great job of removing every bit of thermal paste. Just dab some high grade rubbing alcohol on them and wipe away what is left.

Well, I used pure isopropyl alcohol and q tips to clean it, I should be fine right?

yeah, that's the same thing basically.

That should be fine. The only reason I try not to use Q-tips is that you tend to have to use a lot of them and sometimes if they are the cheap kind, they fall apart and leave cotton behind.

Yep, thats one downside. There is so little of the thermal paste left and it's only on the pin sockets that I hoped a little that it was conducting. The layer is very thin, you can barely see it. Does it matter or can I just let it be?

anyone?
