    I repasted my CPU and GPU right after I got the computer on the 7th using PK1.My temps were way above normal so I repasted using IC Diamond. Temps went way down. I thought PK1 was supposed to be good.

    MOD NOTE:
    Transactions should be held in the NBR Marketplace

    PK-1 is supposed to be decent. Chances are it was a mispaste where something happened with the spread. I've got a tube coming so I'm gonna see if I get similar results when comparing with IC Diamond.

    i think you had bad contact between your cpu and heatsink when you put the PK1 on. As of 2011, PK1 was near the top of available pastes

    ICD-7 does well in bad contact situations, but does not improve when contact improves...so unfortunately, it becomes just an average paste overall. plus i keep telling people to avoid using ICD-7 in laptops because laptop CPU and GPU dies are lidless. The ICD-7 has particles in it that will scratch your dies with repeated applications and it will have a severe polishing affect on the copper heatsink contact which will affect your temps over time. ICD is more meant for desktop CPU's that have metal lids on the CPU dies

    Look here for a good paste comparison in 2011, look at moderate contact for what you might expect in a laptop:

    2011 Thermal Compound Roundup – Results Compilation | Skinnee Labs


    ...you'll notice that ICD was not part of the tests. The reason was (as quoted straight from Skinnee's mouth) " IC Diamond will only be tested after this testbed is ‘retired.’ Due to its severe polishing effect, ICD is not something I can test 15 mounts of and guarantee that the testbed will perform the same after as it did before (it permanently alters the CPU IHS and the block bases). That said, I did briefly test it while pre-testing for this testbed and procedure and I can say it’s really good with Poor Contact but does not improve much as contact improves, making it just an ‘okay’ paste when you have at least moderate contact, which most CPU blocks, most GPU blocks, and most heatsinks do"

    I just repasted my GPU... PK-1 appears to be working great!

    Nice one, glad it is working well. Mine is coming too, hope to find a suitable replacement for ICD. The GPU die is pretty worn already lol.
