    Hey everyone, I have actually been very content with my Razer Blade Pro 2019 temps.
    During light loads such as web browsing the fans would ramp up for a few seconds and come back down. The most I see on the CPU while playing Modern Warfare is 95C and this is with the fans running maxed out. However, I still believe this can be improved on.

    Would it be worth it to do a repaste with just kryonaut? I have tried liquid metal on previous blades but the temperatures would degrade after a year.
    Also, if anyone can guide me on which screws needed to be removed on the top left and right of the heatsink before I just start prying it off. o_O

    Its a laptop, at least yearly repaste and cleanup is expected.
    At least kryonaut is easy to cleanup and repaste compared to the stains LM leaves on the heatsink.

    I have the late 2019 with 2080. After hours of modern warfare, wow, overwatch usually see a max of 92c and an average of 59c. i consider those temps to be perfect

    Just wanted to update everyone that it was actually very simple to remove the heatsink. I repasted with kryonaut and dropped my CPU temps by about 5-10C all around. The fans don't even ramp up while web browsing and YouTube. :p
    I might consider liquid metal sometime in the future if I get even more curious.

    Hi,

    I've got a new Razer Blade Pro 4K Touch 120 Hz laptop. The overall temps are not too bad. Especially, GPU temps are perfectly low (max at 70). The only thing is that CPU temps peaking at around 95 playing far cry new dawn at high settings 2K or 4K resolution. I am thinking about repasting this laptop as you did. Could you give me some tips and tricks on how to remove the heatsink? I couldn't find any guide on youtube with this new razer blade pro model. Thanks in advance!

    In addition to the obvious screws, there is one in each corners near the hinges. They're kind of hidden under wires. I found that it was helpful to take the fans out as well.

    Note the little pieces of plastic over the heatsink in the back. They prevent you from lifting it straight out. I found it easiest to lift up the front then pull it out at a bit of an angle. You will also of course need to be careful putting it back in. Make sure you're not dragging it along the CPU/GPU die while you do that.

    Are there 11 screws overall that are keeping the heatsink in place or am I missing some hidden screws?
    Which thermo paste would you recommend to apply?
    What is your opinion about a cooling pad? The opinions are very conflicting. I have read some feedbacks that they can actually decrease the temperatures while other comments say to expect no improvement at all only waste of money.

    I used kryonaut. Not sure I have a particular recommendation, other than any one of the high end pastes.

    By cooling pad do you mean something under the laptop with fans? It should help if they move the air in the same direction (i.e. it isn't fighting against the fans inside the laptop), but I don't like them. If I was OK with the space a cooling pad takes up, I'd just get a not-thin-and-light laptop and have the extra cooling built in with far less hassle.

    I haven't counted the screws, but 11 sounds about right. One screw near each hinge, one down near the battery (holding a thin piece of copper over the PCH), and the rest over the CPU & GPU.

    What was the overall improvement in temperatures while gaming in your particular case after you repasted you razer laptop? Did you repaste a new laptop after you had bought it or did you repaste it after some time?
    Is it enough to buy 1g thermal paste or should I buy a bigger amount of it?

    1g is plenty for a few repastes. There have been rumblings of fake or old kryonaut; you may wish to buy from their authorized US distributor (you can find that on thermal grizzly's website). I bought from Amazon and I'm 99% sure I got the genuine stuff.

    My laptop was about 8 months old. While I didn't have a good reference point of performance at new, I felt like the cooling had degraded... but it's very possible I was just pushing it harder. I noted the following changes in thermal performance (same benchmarks before/after, same room temp, etc):
    Balanced mode, fan locked to 3k RPM, 35W on CPU and 100W on GPU: roughly 3c improvement
    Custom mode, 55W on CPU and 90W on GPU (nvidia driver bug): roughly 10c improvement.

    No real change in GPU temp


    edit: "same benchmarks" should be "same stress test"
