    well i recently changed my heatsink and fan for my cpu, worked better than my original one and it was at avg of 130ish degrees F"

    then i bought thermal paste and the temps like 126 - 130ish still. did i apply it wrong?

    if its still normal thermal greese, i wouldn't expect a difference from before you applied new greese.

    if you want thermal compound that will make a difference, get arctic silver 5 instead of thermal greese. its a little pricey for a little tube of compound but its more than you will ever need and its the only stuff i trust as thermal compound.

    you could also be right about applying it wrong. if you add too much, it will do more harm than good. if you added too little, then its not effective enough.

    before you do that, how much did you already add? a drop about the size of a grain of rice should be enough. also be sure to spread it evenly. you want a nice even coat so that you can still kind of see through it but not too clearly.

    That is probably too much, but we'll see what happens.

    Perhaps you should clean off the cpu and heatsink with some rubbing alcohol and a coffee filter and reapply. Use about a grain of rice size drop of Artic Silver five. Spread evenly with a razor blade or credit card and reseat the heatsink. What kind of heat sink is this, stock? Maybe you could open your case and aim a small table fan to blow inside until you sort out your temp issue.

    just a little warning, if you are going to use a razor blade. DO NOT slide it sideways. my hand slipped a little and i scratched my old stock heatsink for my A64. that long scratch raised the temperatures a few degrees C.

    i recommend using those clear plastic laminents used to hold the base of the heatsink. the edge is round so its perfect.

    let it settle, at first, the temperatures are a bit higher. the thermal compound needs time to fill in the little gaps. it will be a little hotter at first. i suggest not leaving the computer on too long. turn it off if you are going to walk away and you know that you aren't coming back after a while.

    I do have a couple questions. What type of processor is it? What heatsink and fan are you using to cool it?
