  1. Hey Guys!

    I have just recently bought a new i3 processor for my computer and fitted it into my 1155 socket, however I am currently waiting on a new PSU being delivered so the processor has not been used at all yet. After I fitted the processor and the heatsink I checked on it the next day and it was stained even though no power has been supplied to the computer whatsoever since its been fitted, Could anyway tell me whats going on?

    Here is a picture

    Well, that just looks like your thermal paste being spread out. Probably from the fitting of the HS. There is no problem here. However, I would probably clean and reapply before putting the HS back on.

    Ok I will make sure to re-apply before I start up thanks for the advice!

    Thats not a stain, its thermal compound that bonds the heat-sink to the CPU. I hope you have more thermal compound, because it is best to redo the thermal paste application process every time you remove the heat-sink.

    It hasn't explicitly been said: the stain is required. :)
