I posted this up in the vid card forum, but since so many senior people are here, I thought I would post my TIM issue, I can't believe I did this.
The thermal paste I am using is Artic, MX-4, nonconductive.
I was installing my HSF, and by accident, a SMALL amount of the TIM ended up in 3 of the little "slots" of one of my video card's slots. I haven't installed the card YET. The 3 holes weren't filled, more like covered. I took a pair of jeweler's forceps/tweets to lift out as much of the TIM as possible. The tiny holes seem clean, but I can't tell, 100% as they are so small. I'm sure using the forceps may have pushed some of the TIM further down, but I can't be positive. I'm ticked at myself.
What should I do?? Just not used to a mATX form factor, my hands just grazed the top of the vid card slots, and poof the past landed.
