    We’ve been informed that one of our users decided to open the chassis of the new Blade to see if he could improve on the thermal performance of the Blade and replaced the thermal paste as well as made some modifications in a bid to improve the thermal performance. Some of the posts that were made are here:
    and here: http://www.reddit.com/r/razer/comments/2wn5fr/stock_thermal_compound_and_heat_pipe_design_is/

    Unfortunately, after the user made the changes, he experienced much worse performance from his system and we’re giving some insights as to the reasons why below:

    At Razer, we have some of the top thermals experts on the planet and our thermals designs are usually at least a generation or two ahead of the rest. For example, one of the concerns the user had was that in the 2013 Razer Blade, we had used heat spreaders - while in the 2014 and 2015 Razer Blade, we had removed the heat spreaders which led him to be concerned that it would have decreased performance.

    Historically a copper slug (or “heat spreader”) has been the point of contact between the largest point sources of heat (CPU and GPU) in order to ensure that hot spots from the package did not miss contact with the heat pipe.

    Today, CPUs and GPUs are much better at evenly distributing heat across the entire surface of the package. Our thermal analysis has shown that the application of a heat spreader does not substantially improve the spreading of heat, and other factors such as heat pipe thickness can have a much greater impact on thermal efficiency and capacity within a constrained product thickness.

    In fact, in some cases (such as the Blade) having a heat spreader located between the CPU/GPU and the heat pipes can act as additional thermal resistance and can lower the efficiency of the overall system. Though it is less conventional to do so, Razer chose to eliminate this inefficiency.

    For the 2015 Razer Blade we redesigned the thermal architecture by modifying and improving the efficiency of the thermal assembly. As part of the redesign, we removed the heat spreaders while substantially increasing the TDP of the system. As such, the 2015 Razer Blade has the same form factor of the earlier 2014 Razer Blade but is able to contain a much higher TDP without an increase in skin temperatures.

    We understand the user also referenced some thermal solutions of other brands, and as many brands out there reference our earlier thermals designs, they are usually one generation behind, a good example being the heat spreaders that we used in our 2014 design.

    In respect of the user’s concerns of the “stock paste”, the thermal compound that we use is a custom paste with very specific characteristics and was designed to be used specifically with our thermal architecture. This is a custom paste and we do NOT advocate re-pasting with other thermal compounds out there as it would be likely to lead to decreased performance and is not covered under our warranty.

    TLDR: The new Razer Blade 2015 has a redesigned thermals architecture that substantially improves TDP over the 2013 and 2014 Razer Blade. Our thermals solutions are custom and we do not advise customers to open their systems or make any modifications as it is more likely to lead to decreased performance and would void your warranty.

    Always nice to see such an explanation. Cheers for sharing

    lol, poor guy, hopefully his blade can still run a few games. Why you would instantly void your warranty on something THAT expensive and tinker with it is beyond me...

    @Destrok, because 5c is incredibly big difference. :D

    LOL. poor guy. underestimating razer's engineer. he should have known that when he replace the thermal paste and resulting in an increase in temperature. he must do it wrongly. either material or designed or something else. one does not simply blame people when he replace something and ends up at the opposite side.

  6. Also because i wouldnt like seeing my hardware running at a 'for me' too too high temperature. Although the manufacturer says its allright. For example; my work macbook gets to a scorching 85c while watching movies. This is a 2011 13" with poor thermal design. But its within range of Intels max temp.

    That guy though... a bit silly... Does he even know what exactly is in place there before complaining? Lol :stuck_out_tongue_winking_eye:

    Why fix something that is not broken? And lose the warranty? Because he thinks he can make it work cooler by 5 degrees? I'm laughing so hard at this thread. The best part is that he keeps blaming Razer for "bad design". :D

  10. so..... Im wondering. Did he delete one of his posts out of rage/embarrassment? :D

    Well he must have thought that the blade was just like every other manufacturer assembled laptop/computer product that uses stock stuff and can be improved by common steps (like what people do for several years now - changing the thermal compound, lapping etc etc). It is good to know that Razer DID actually put some testing to their products instead of just "marketing"

    I see a lot of the comments giving the user grief for what he did - to be candid, in most cases, replacing the stock thermal paste etc would give a performance boost because most manufacturers cut as much cost as they can everywhere.

    With the Blade however, we designed it for me, for you, for ourselves. Basically we tuned it and used all the best, top notch cutting edge stuff from inside to outside - and made the ultimate laptop for ourselves. So cut him/her some slack - he/she wouldn't have been wrong 99% of the time.

    He did blame Razer for his issues, to quote him: "biggest design failure I have seen in a long, long time.". 90% of the grief comes from there.

    I wish Razer communicated this thoroughly about all their products.

    And this, *pause* is why you don't mess with Razer and its engineers. pffff :stuck_out_tongue_winking_eye:

    I don't see a difference between the 2014 and 2015 thermal assembly. What changed?

    I actually follow those forums, and they're one of the reasons I pulled the gun on the Blade 2014; most people around there know what they're doing.

    There are a lot of people that like to tinker with their gadgets, myself included; though I usually err on the side of safety and wait until the warranty is up, heh. A long time ago I had an ASUS G73 that started overheating, and thanks to the those forums I opened it up and repasted it, worked like a charm!

    That being said, I've come to think that owning a Razer Blade is a lot like owning a luxury car, like a Mercedes. Heck, it is a lot like a "middle age" crisis thing, in which I was too young to have the money a few years back but now that I have it, I buy an "overpriced" but beautifully designed laptop.

    And I wouldn't mess around too much with a luxury car :)

    What I would personally like, though, is know what have the engineers at Razer done. I just love technical articles, and knowing what redesign they did would be amazing to me. One should always know what is under the hood of their luxury items.

    Thank you for your info. Now i know 99% do that and increase my industrial engineering knowledge. but blaming razer is the 1 at fault here. i guess he learn his mistake from this post and improve.
