    Thermal paste


    Hey guys,

    So I was hoping to get some clarification (as well as personal opinions) on thermal paste application.

    I have heard many different ways of applying thermal paste, and I am guessing they all work.
    The real question is, how MUCH?

    I just have a feeling I put on TOO much on my new CPU and its causing some heat buildup instead of cooling.

    Well LB that post should about do it. So did you apply to much?

    Looks like I may not have applied overmuch, but it could have been done better.

    I will pop off the cooler and try that method later tonight. Hopefully I will see a temperature drop.

    Not changing the subject, but your specs show that you're using the SAMSUNG Spinpoint F3R.
    Is it quiet? Fast?

    I don't know about fast, it is an HDD. But I don't hear it, so I guess it's quiet (my fans make more noise).

    Alright, reapplied (and redid my watercooling loop ) thermal paste thinner, temps do seem a bit lower.

    If your brain works better with concepts than with rules then this sage advice that I got from a fellow geek many moons ago has always worked for me:

    If you look at a seemingly smooth piece of metal under an electron microscope you will see that the surface actually looks like a mountain range - many peaks and valleys.
    To have perfect heat transfer the two metal surfaces should be touching on 100% of the surface area of both plates.
    But when you go and try and mate the two metal surfaces together the peaks and valleys create voids that greatly reduce the thermal transference.
    The purpose of thermal paste is to fill those peaks and valleys, at that microscopic level, to increase the total contact surface area and eliminate those thermal breaks.
    But you do not want to use so much paste that it actually starts to insulate the plates from each other. You want some metal-to-metal contact (peak to peak).

    So that is the trick: you are just filling the holes, not frosting a cake!
