    If you own a Razer Blade 14" or any Razer Blade for that matter and experience poor thermals on the CPU, for example, when running anything CPU intensive some cores shoot to 100 deg C instantly while other cores will hover at a reasonable 70 deg C, I've determined the cause.

    After spending literally hours with Razer Support about this and listening to them INSIST that if I run the latest version of the nVidia drivers and Windows updates it will solve my thermal issues... I gave up. These guys... I mean, no words. I gave up and just opened my system.

    The CPU is on the upper left. Look at the heatsink!

    You see how the heatsink for the GPU is flat copper, that's how it's supposed to be, an even thermal block across the PU. However, on the CPU, there's big gaps running along the entire CPU surface between the heat pipes! This means that some CPU cores will have direct contact with the heat pipes and some cores will literally not be touching the heatsink at all.

    As a bonus to my poor thermal performance, whoever assembled the laptop forgot to take off the protective plastic on one of the thermal pads, thanks guy.

    "But isn't this normal in all laptops?" You might ask. No! In fact, a quick google search of laptop heat sinks for MSI, Acer, and literally every other laptop you can think of have solid, flat heat spreaders over both processing units. Seriously, google it. Every. Single. One. Other than Razer, that is.

    Because of this manufacturing oversight, I highly recommend against getting a Razer laptop. I love my laptop in every other way, except for this. And that the first one was DoA. Maybe this will be fixed in future Razer laptops. Maybe you got one where the heat sink aligns perfectly with the cores on the CPU so you don't have this issue. I didn't get one of those. And if you're thinking about buying one, you might not either.

    If you have a Razer laptop with this issue, and you can test by running Prime95 and seeing if one of the cores immediately jumps to 100 while another core stays around 70, then you can bet your top dollar that this is the cause.

    ========================

    UPDATE: I cleaned up the stock Thermal Paste and replaced it with Liquid Metal (Thermal Grizzly Conductonaut) and WOW, this laptop performs better than ever!

    Running Prime95, all 4 cores stay at 45 deg C and slowly rise to 70C and then stop. AMAZING compared to before where 2 cores would jump to 100C instantly and 2 would jump to 70C and then rise to 100C.

    And for gaming, my temps on both GPU and CPU hover around 75C. I could not be happier, it's like having a brand new laptop! It just sucks that you have to void your warranty and take apart the laptop just to get it to perform like it should have from the factory.

    ========================

    UPDATE2: I was wrong. The CPU is actually on the right and the GPU is on the left. So the GPU is the one that does not have a flat connection to the heat pipes. This means my issue with the CPU temps were because of a bad thermal paste application by the system builder and little to no QA after it was built. Manually cleaning and replacing the thermal paste on both the CPU and GPU, as well as removing the plastic left on one of the thermal pads, resolved my thermal issues.

    The cause of this issue has been confirmed to be related to the system builder and lack of Quality Assurance.

    How about placing a thin copper plate in between the heatpipes repasting the grease? My blade pro 7820hk core1 always goes above and beyond the other ones.

    lol @ protective plastic on thermopad, never seen something like that. And what a mess, even motherboard is covered with thermal paste.

    Copper plate will be a good option, just put more thermal paste between the gaps, then "stick" a copper plate to it.

    It is "normal" saw similar or even worse cooling solutions on other (but non-gaming) laptops. Thermal paste on Dell laptops looks like a pigeon sh**, and it becomes hard after few months.

    Holy crap... they have to RMA your laptop and give you one new and fully working. this is absolute a bad notebook that doesn't will be reach public selling. try to contact an amdin here to get a support on support request.

    This is exactly what I experienced on my blade before. There was a hugeeeee long thread on Notebookreview's forums about trying to figure out why the repaste temps were so bad. Razer's CEO actually took to social media to claim that Razer's cooling technology and engineering was "years" ahead of the competition. Actually, it's just cheap cost-cutting. Sorry for your Blade.

    The CPU side is the flat copper shim....the direct to heatpipe side is the GPU. You got a badly assembled unit, unfortunately, since many blades out there don't have a core temp differential issue. That being said I wish they used a flat copper surface for the GPU side as well.

    Sorry to hear your issue. In that case you should contact the support with those proofs pictures and get RMA. Poeple has various issues with a gaming laptop and to minimize it they’re running tests inside RMA period. Running intensive program like stress test or games Let’s say AC Origins, will any laptops cpu temp to peak even a desktop cpu. So poeple undervolting the Blade for a better thermal, on first stress test without uV mine was fine but for the games, ACO, 7700HQ needs to be undervolted for lower temperature, light games like OW, destiny 2, CS Go, o don’t even need to uV or control the thermal. If within a year the thermal (CPU cores/GPU) is already bad, I agree as you said it could be a manufacture process issue.
    Really comparing with MSI laptops, it runs hotter and I think louder even on thicker their 13 inch laptop (Phantom Pro, tried the 1060 before bought Blade 14). Though your picture proofs the reason, maybe Razer should not only put money on the development research, but also on QC.

    Congrats, and enjoy it! So repasting avoids the warranty? Because i think there’s no seal or something similar with that, did you ask the support before. Well if yes, so far I know only dell that allows user to repaste but you seems have to explain the reason.

    What year is your blade 14? Just curious.

    He has late 2016 Blade 14, from past comments.

    Welp, that would explain any disparities. Just a "quality assurance" problem like most of Razer's flaws can be traced back to. :stuck_out_tongue_winking_eye:

    This is why I prefer to get boutique laptops instead just because each one is individually assembled and tested instead of a production line where "faster is better" is the sentiment. But I'd like a Blade one day once they get these issues resolved. :)

    you might want to overthink that ;) the cpu is on the left Bro .. the other chip that you think is the cpu literally says NVIDIA on it ;)

    That’s what the ts said. The left is the cpu and the right one is the gpu. You high bro?

    my bad i meant the right is cpu but yea you can see that if you remove the thermalpaste that the left chip says NVIDIA on it ;)

    Thank you for posting this. I recently had to remove a bulging battery in mine, and as soon as I put the chassis back together I immediately regretted not taking photos because mine looks...eerily similar to yours. Just another example, in my mind, of the QA/QC problem Razer has. Great design ain't worth squat if things can't be built properly.

    Thank god I did not go through all of this. I am able to run prime95 no problem by simply undervolting the CPU. This keeps temps in check with intel standards and allows all 4 cores to run max clock at 3.4 for extended gaming sessions etc. Sure the CPU will creep up to 90c during the small FFTS test but it still maintains full clock speed and never gets that hot during gaming. A much faster fix for those who don't want performance loss or overheating.

    On a side note... if you have a bad thermal paste job then this wont help so much. In OP's case he had to make some physical tweaks under the hood. Most of you should not. Happy gaming!

    and now i agree with you ;) thats exactly what i also noticed ;) after changing the thermalpaste to the Noctua paste on my blade, the temps went way better under load ( althoough i never had throttling )

    Can anyone provide temp numbers before/after re-pasting? (Or just after if you're not sure of the before)
