    I often clean laptops from the inside and take out and clean the heatsink and I have to change the gpu thermal pad. Which is the best kind that gives better cooling heat transfer etc? Also which thickness is better? Is it ok or better to use a 1.5 or 2.0mm pad on a gpu that used to have a 1mm pad? There's so many of them but i don't want to get cheap ones that will not cool efficiently.Also is AS5 the best thermal paste? is there a superior one?

    I like ICD better than AS5. Its not conductive and it works well when you add thickness, where as AS5 works better the thinner you can get it.

    Does it lower the temps better than AS5?

    As5 is great but cure times are pretty long. Really most top end pastes will work about the same if applied correctly.

    I did AS5 on my Asus G73 GPU and it lowered the temps over the original paste. But after about 6 months I switched it for the ICD and it seemed to drop the temp a few more degrees.

    I have also used it to replace thermal pads in some Dell Latitudes, it worked great there as well.

    Been reading about it now and it seems pretty good lot of people say its better than AS5. I will order it once my AS5 supply runs out.

    The answer to this question pretty much always end up between PK-1 or ICD.

    Personally, I would say get a small tube and try it unless it is outrageous more expensive.

    Well I found a really cheap thermal compound, 907.2 Grams for $7.55. Compare that to 1.5 Grams for $8.49. And it works just as good as ICD. Links:

    I been researching and it seems like the best thermal pads are from a company called phobya there are 2 kinds 5w/mk and 7w/mk. I think the ones I'd been using were 3.2w/mk. The better one for laptops seems to be the 5w/mk because it is more flexible and compressible unlike the 7w/mk which are very hard to compress. Anyone had any experience with those?

    I really have great doubts that your "special" thermal paste that only costed that much works as well as ICD.

    thermal pads are different and worse then thermal paste. the best thermal pads have 12w/mk.
    phobia doesn't make thermal pads, they are just a brand, the product itself is made by someone else.
    the thickness depends on the notebook model.

    AS5 is conductive and nowadays there are much better, cheaper, and non eletrically conductive alternatives.

    if you want something good and cheap get this:
    Newegg.com - COOLER MASTER IceFusion 40G RG-ICF-CWR2-GP Thermal Compound

    If you follow the third link on my post you will find a link to a website where they test all the major thermal compound and some alternatives including mayonnaise, chocolate, and butter. Numbers cant lie.

    Thermal pads are necessary to use in situations where the gap is just too big and thermal compound cant fill it up it would drip on the sides or something. That's the way laptops come, with a thermal pad installed. That's how the laptops gods created them.

    I've been researching more on the subject and phobya indeed doesnt make the thermal pads; some other silly company does. In my journey I have also acquired teh knowledge that hp doesn't make computers laptops its some other compufactory in china with another equally silly name.

    that review is biased and unscientific and often pointed out as a bad example.

    thermal pads are not necessary. they are a cheap way to fill the gap in notebooks. they have very poor performance compared to thermal pastes. that's why as you can see around here in thousands of posts that people use paste and not pads. a good paste will not drip to the sides or something.


    there are no laptop gods. there are companies that want to make money selling laptops.

    hp does make some laptops of their own brand. I don't understand what why you say Quanta computers, one of the biggest notebook manufacturers in the world, have a silly name.

    I wouldnt say alot better, but with the better cure times and being relatively same performance as my tried and true AS5 Ill be going ICD when my supply of AS5 is gone.

    AS5 was trully the best TIM like 15 years ago. it WAS great back then. now it's ancient and there's cheaper, better, non conductive, easier to apply TIM's then AS5.
    Actually the only reason why people talk so much about it is because of the reputation it had for many years.
    nowadays there's no reason to use it.

    It's still a very good paste, and like many things if I have it laying around (and I have 2 tubes left) I'm going to use it before I go out and buy another paste. No sense in wasting good paste for such a marginal gain IMHO. I personally bet the as5 I have will probably outlive my newish m4600.

    So back to thermal pads, which would be best used in a Sager NP8170? I have a 7970M upgrade kit coming from Sager, and am awaiting a reply if that includes thermal pads. In the mean time, I thought I'd look for information on thermal pads while I wait for a response.

    I am assuming that the thickness needed would be similar to thermal pads used on 6970M and 6990M GPUs in Sager machines, but I could be wrong.

    As for thermal pads themselves, they are a requirement to have on your vRAM and other components of the GPU, are they not? Surely no one is going to use thermal paste in these spots? Wouldn't that create a huge mess and insulate the memory controllers and vRAM?

    Use a copper shim with the same thickness as the thermal pad. Use thermal paste on both sides and you will have better results. There are plenty available on ebay!

    Been thinking or cleaning and re pasting my m4600 and I might head up to home depot or lowes and cut one myself. But Id be interested in knowing who around here does this.
