    So, was really frustrated with the temps and since the i7 came delidded already I decided to check the delid.
    It looked like this, the top part on this img seems to have barely any contact:
    [​IMG]
    So I cleaned everything carefully with some alc, scrapped the silicone with fingernails off the pcb (with knife on the ihs).
    I repasted with mx4 between chip and ihs, since thats all I have and I refuse to touch liquid metal ever again.
    I dont have silicone either so I just ... carefully put the lid on and let the metal thing keep the ihs in place. Its doesnt seem to be able to move.

    Now I can run XTU on stock with no uv on autofans without any throttle :D
    Lesson learned: Do it yourself !
    Im not complaining about the prelid though, cutting that silicone is 100% easier than the Intel glue.

    Temps on XTU with autofans:
    [​IMG]

    The core temps are now all even, when under load. :)
    On idle core 0 is still 5° hotter, but I think the fans actually turn off completely since I keep hearing them turn back on. Also the heatsink is probably still not even on the ihs.
    This is my TIM spread which looks pretty thick to be honest, I cant get it thinner though:
    [​IMG]

    Ill keep using it on E3 levels with uv. The fan is so slow now, even in GW2 under heavy load.
    Im falling in love with my laptop again :D
    Time to change my sig :p

    Some variations in core temps is common enough to be normal. As long as none of them run too hot (read: thermal shutdown) there is nothing you need to worry about.

    Now it´s looks like better your Temp :p
    But you can try some thinks.

    1. check the CPU Heatspreader. Is it flat or concave? Flat ok but concave you better polished it.
    2. If you polished the Heatspreader now you can polished the Heatsink

    3. Use a thinn layer of TIM, thats too much
    4. You can undervolt your CPU with the stock clocks. 1.252V is too much for stock 44, 44, 43, 42 clocks. Or you have a bad 4790k that need so much voltage, but i don´t think so ;)

    1. Will check next time I open it :) But the gap is already big, If I polish it, the gap between ihs and heatsink will get bigger.
    2. Thats a nice thin layer of TIM :eek: wish mine was like that. Only my GPU has thin layer like this, even if I put too much it will just be pushed out with a thin layer remaining. Thats why I think that putting less TIM on CPU will create small spread :confused:
    3. If I use less there might be no contact :confused:
    4. Yes, I just used no uv so I can compare the improvement to my last test ;)

    Even if I think about telling my seller about the gap, apparently swapping CPU and even just removing the heatsink voids the warranty :oops: "Because one mistake can lead to parts overheating" was the reasoning.

    I forgot what it was but figured it out when I was in there a week or two ago (currently RMAd).
