    What's this on my CPU/GPU?

    My old laptop's screen was recently destroyed (That's what you get for lending it to a friend) and I thought I'd go ahead and sell the parts (3610QM and 675M).

    [​IMG]

    Problem is, under a layer of particularly hard to remove thermal paste, I found these marks on both my CPU and GPU. I just can't decide whether its just caked on thermal paste residue or genuine physical damage. (They're completely functional as far as I'm aware)

    So, do you think they're fit to be sold? If not, any idea how this happened

    Thanks :)

    PS. Sorry for the massive, not particularly clear photo.

    Did you happen to use IC Diamond? Because if you don't thoroughly dissolve it before removing it, it really can scratch up a die.

    This is what it did to my 4940MX.

    Yeah, I did. Didn't think it would be that fickle of a paste. Are these marks serious at all?

    No, just cosmetic. Some system builders will void your warranty for it and it drops resale value, sometimes sharply, but it doesn't affect the functionality at all.

    That's good to hear, I was hardly looking to make a fortune off of them anyway. Lol. I'll stick with MX-4 over IC Diamond from now on, though.

    Thanks for the quick response!

    Don't use MX-4. Get GC Extreme. MX-4 not only performs worse than both IC Diamond and GC Extreme in low pressure mounts (laptops), it pumps out quickly. GC Extreme doesn't have the longevity of IC Diamond but it lasts a lot longer than MX-4.

    I've had those exact results from IC Diamond.

    No matter how careful I've been and soaked the paste for awhile in bernal remover it always seems to leave scratches.

    I now avoid it and have had great results with PK-3.

    MX-4 was garbage in my laptop.

    The scratches are purely cosmetic and don't affect performance of the TIM.

    Agreed... Use Gelid GC Extreme... MX-4 is total utter junk and it will pump out in no time :)

    IC Diamond will last years, GC Extreme you might have to replace after a year.
