    So uh, how will this compare to IC Diamond again?

    I am somehow skeptical of this.

    There have been 'sheets' for years and years. I remember seeing them on OEM CPU's 10 years ago.

    The thing about grease is that it fills all the microscopic imperfections on the CPU die and heatsink. I don't think a sheet can do that as well as grease can.

    It says "silicon highly-filled with carbon fibers" if the fibers can fill the unevenness to should work.

    We need to have to have a more consistent way of applying thermal interface material, and this might be it.

    I would not call it complete BS if the thermal sheets would last longer (need replacement later way later) than the thermal compound. This was probably meant for people who are completely clueless about how to apply the thermal compound. If it'll last longer than thermal compound I'd purchase this rather than crack my laptop open down to the CPU several times over the years to change the paste.

    This actually looks like a perfect product After the cpu/heatsink is lapped and polished to a flat, mirror-like finish.

    Of course, an experienced TIM applier would get even better results anyway after lapping/polishing the cpu/heatsink...

    Hmmm... how much would this cost (per application)?

    For general use, it's a good idea. For optimum performance it is not. I'd much rather have factories use this over paste because paste can be botched up so easily, I always get significantly cooler regardless of what laptop I buy when I repaste myself.

    "The sheet is 0.3-2.0mm thick. Its thermal resistance is 0.4-0.2K·cm2/W"
    what an incredible piece of crap. there's MUCH better thermal pads since many years ago.

    they should just apply our thermal paste in a vacuum environment :p zero chance of having air bubbles.

    Actually really well lapped cpu & heat sinks can run just fine with out TIM, i saw one guy who gain only a 2c drop in temps after applying TIM (after lapping)

    You should always add TIM. Even with the best laps there's always microscopic fissures/gaps that need to be filled.

    I bought and applied on my desktop a supposedly 16W/mk sheet earlier in the year only to find it performed worse than when using thermal grease (i.e. that supplied with Thermalright heatsinks). And yes I did apply it as intended.

    Thermal grease is simply the best choice. If you ask me they should rethink the whole heatpipe cooler designs instead i.e. what's the point of beefy heatpipes (desktop or laptop) if the area at which they touch the fins is so tiny so little heat can get passed along and the dissipated.

    Sound like it is a gel structure more than thermal pads you guys are thinking about.
