    About re-padding my notebook's GPU components

    Hi, I've asked this question in the MSI forums website, but since the place has a lot of traffic and a lot of questions being asked constantly, and I have not gotten an answer there (with my post already bumped down to the third or fourth page), well I decided to ask the same here, in case anyone knows and can give me some advice.

    My notebook is the GT72 2QD with the Intel 4720HQ CPU and the 970m GPU. Now, I overclock my GPU for some games, with the overclock dependent on the game: more demanding games require I overvolt to get a higher core clock.

    The GPU is doing fine, and I've never gone above 75°C-78°C (with the notebook fans at maximum) but that is a bit high for my tastes, even if it was running the Valley Benchmark. That was during spring, though, when the ambient daytime highs were about 30°C -- 10°C below what they are these days: we ARE in the middle of summer and recently they are around 40°C (104°F) (i.e., it has not been below 100°F-102°F for weeks, with this week not going below the 40°C mark, and many days a couple of degrees hotter); as I don't live in a refrigerator, even with the air conditioner running at its highest setting means I cannot use my laptop for gaming during the day, and since I kind of want to sleep at night, I am left with a rather expensive Facebook and YouTube watching machine --- for that I can use my HP notebook too.

    I want to keep the GPU components as cool as possible, and I think that using 17W/°mK pads would help, especially the VRMs when I overclock. Now, those pads are EXPENSIVE, and I don't want to buy the wrong ones, so my question concerns the thickness of the pads that I need -- figuring out the thickness may be easy, but NOT cheap, so if anyone knows this beforehand it would really help me out.

    But of course, that would make a repaste necessary. I am concerned, however, since I read somewhere that IC diamond paste can be abrasive and maybe even end up corroding the heatsink, so what does anyone here recommend?

    Thanks in advance
