    **** I added a short video that shows the temp differentiation*******
    Guys, you know the problem :)
    And i think i found a solution, at least it worked for me.
    Here is the miracle;
    ? used thermal pad over the heat pipe of the cpu, and it worked nice, In sum; the pad transfers the heat to the cover(thanks to lenovo its metal), and cover spreads heat , and this lowers the actual temp of the cpu.
    I put the pad on the red rectangle.

    Because i couldnt find thicker pad, i bent 1mm one and used like this; if you can find a thicker one like; 4mm or 5mm it will transfer heat more efficiently.

    Of course you have to do it longer :)

    And after the installation; you can see a little part of the thermal pad under the cooling vent.

    And here are the results;
    Ambient temp is 27c and 10 mins of prime95 max heat test. Couldn't go over 86c
    [​IMG]
    And the temps after 10mins of GTA V , all settings are at maximum as to my cpu and gpu.

    And these test were made without a cooling pad. And there is no room for worrying, because thermal pads are non-conductive so it will never cause electrical short circuit.
    So give it a try people, i hope it works for you too.

    Over 5hundred visitors and none gave it a go?
    At least im pretty well satified with the mod.

    actually, increasing surface area of heat dissipation is better compared to just using more airflow

    The reason is that I don't have a Lenovo! :)

    Nice simple mod - and those are the best IMHO.

    That's a pretty simple mod, I'll have to try this out, thanks!

    I may have overdone it but who cares. I gave it a try and used the heatsinks (IHS) extracted from a dead PS3 . So far not so much of a difference in actual temperature ranges(perhaps a decreae of 4 -5 °C), but at least it gives it some heat inertia so that it takes longer to reach higher temperatures.
    Thinking of replacing those pads with actual thicker aluminum pieces and see if it improves things.

    Hi there,
    if you use copper shims, it will transfer heat more efficiently.
    And be sure you fasten those shims as they are electrically conductive materials.

    I already replaced the thermal pad I had put on that aluminum heatsink above the CPU by an aluminum piece. Will take pics later on.
    The piece is thick enough to be held on by the pressure of the case so no screws were needed. I will see about getting a solid copper sheet that is thick enough to be held out by pressure of the case (And thus maximum heat conductivity).
    I am already getting lower temps,about an additional 4-5C.
