Sony demos silicon sheets that could replace thermal paste

  1. Although applying thermal grease isn't rocket science, there is some guesswork involved, especially if it's not something you do often. It's not uncommon to see questions about the application of thermal paste or even horror stories about the overuse of…

    this is very interesting, only the so called average conventional greese can range from 0.5 degree of difference to 6 degrees. it'll be 'really' helpful to know what kind of conventional greese was used for the test.

    Not to mention high end compounds can out-pace the average Joe grease by at least 3 degrees as it is. My guess is they're comparing it to their own "best case scenario" paste, which chances are isn't all that good. I'd like to see it compared to IC Diamond or Indigo Extreme to get a real comparison.

    Yea, they should compare to higher end thermal solutions. Otherwise, this is looking good.

    You know, even if it isn't as good as the best thermal compounds and even if it isn't sold to the average consumer, we can ALL feel more comfortable with the fact that OEM's can consistently apply the same amount of thermal grease to each and ever processor they use or produce. May I remind everyone of Apple's literally botched grease efforts in their older Macbook Pros?

    This is not new. I have purchased numerous heatsinks with a "strip" of paste pre-applied.

    Seems weird buying a part for your computer that's from Sony that's other than disc drive.

    @ spydercanopus: those are made of thermal grease. The "new" part is instead of using thermal grease, they use silicon and carbon-based thermal sheets.

    This isn't a "strip of paste"... It's a pad that claims to be as good as paste.

    This comment will probably generate some responses telling me I don't know what I'm doing. Maybe I don't....

    I've used Arctic Silver 5 and Arctic Silver Ceramique on maybe 10 different occasions. I've also used Radio Shack's "thermal compound". Radio Shack's stuff is much easier to apply and I haven't noticed any 'bad' temps by using the RS stuff. I don't overclock, so perhaps that is some of it. But I'm not really convinced the expensive stuff is worth it.

    Maybe I just apply wrong, but I follow the instructions given and I've watched some youtubes and whatnot.

    At stock frequencies you really won't see that much of a change. Only a few degrees C. Its far more important that you actually use some type of heat paste and that you apply it correctly without air bubbles.

    And perhaps being able to apply this new Sony silicon sheet consistently is the reason I am excited about this news, besides the fact that there is no clean-up and having to guess how much grease to use depending on the contact surface area of the CPU and heat sink. I just hope that Sony will make it available to the consumer market as well.

    People have mentioned they struggle to lay new paste etc but there was nothing to stop you buying the pre measures sheets applications that Akasa made if you failed so hard at the old cardboard routine.

    I would think if you used cardboard to spread the paste you were already failing. You have a pretty high risk of flaking fibers from the cardboard off into the paste. Credit card or other similar flat edged plastic would be a better choice.
  15. The last time I measured pressure, I had a result in pascals (Pa) - same as N/m^2 (I'm an engineer). So what the hell does 1-3kgf/cm2 mean? Is that the same as the bending strength of an elephant's trunk?
    Come on... give it to us in actual, recognised units. I can understand 'Pa', 'bar' or 'N/cm^2' but "kgf" is totally new to me.
    And no, kilogram-force is no more a unit than 'cubic pounds per arc-minute' is a unit. Just sayin'.
  16. Really cool SONY. Lets hope this doesnt backfire in the PS4 so please do all the necessary test

    Unless it comes at less than or at the same price, and provides more than 5C of temp drops, it's not worth it.
    Both the methods are inefficient/dangerous, due to the uncertainty in the final thickness and cover area of the paste and inevitable air-bubbles. I've covered that in EACG-II. You can check it out if you like from the link in my sig.
    I haven't replaced my paste in a while, but when I do, I'll attach some pics to show ideal application. Covering the Don'ts would be rather expensive for me.

    I for one use generic paste, and with proper application alone I shaved off 4C. Nothing high end.
    One should note that the temp-freq graphs aren't linear. Once you exceed the stock speeds, the scene pretty much changes drastically. The worst-case scenario is in which one should (I do) look for differences, and not on a happy system.
  18. I deed some of that for my head for this summer for my brain needs to run 3 degrees cooler....
  19. If you replace deed with need. It makes more sense.

    All these great innovators at Sony and all they come up with is a solution to thermal paste?

    Goodbye, Sony.
