    Hi all,

    I repasted my laptop a couple of months ago - and now the temps are really high again.

    I'm guessing I need to do it again, but any ideas what I did wrong that it didn't last?

    Thanks!!

    I don’t have special powers to see what you did last time and how much material you applied

    Lol of course, but in your experience do you think it could be because I didn't put enough on?

    Thanks

    Which cores are hot? Have you had a read through the repaste guide by iunlock? Lots of good stuff in there.

    It could be. Could also be the heatsink isn’t level so not getting full contact with all cores.

    Really need to see some data.

    core 0,1,2. I'll have to have another go I think. Triple check the heatsink is level..

    Check your pads to see if they all have about the same level of indentation on them. If not that’s good evidence your pads are causing the issue

    well I repasted today, it basically looked like it completely dissolved...

    Any ideas based on that what I did wrong last time?

    Thanks all!

    It looks to me that (if 2 months ago it was 1st time LM applied) part of LM has reacted with copper and lost its volume a bit.

    During 2nd time LM application I leave the stain on copper, only smooth it, not remove. Now your LM should last much longer.:) as the copper stain has the proper mix inside.
