Razer Blade Pro 2019 Repaste worth it?

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.

 

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.
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"

 

A repaste is absolutely worth it if you know what you're doing. Even a 5c drop is worth it especially most of the stock crud is causing the cpu to be up in the 90's.

You will get an about 7-10c improvement on Kryonaut and about 12-15c on Conductonaut which is what I'm running. My temps were up in the mid 90's and now the max with heavy load is in the low 80's.

 

I agree that it's time very well spent if you're comfortable doing it (especially with how easily accessible the vapor chamber is). But I wouldn't want to imply that it's essential or necessary on this machine... it gets pretty good performance on stock paste.

Still a great machine for people who aren't interested in repasting.

 

I am wondering which one is the right screw near the hinges that is holding the heatsink? Is it one of the five screws that I have marked? Or is it hiding behind that cable (see the question mark)?

 

Now you're really making me doubt myself, I wish I'd taken some pictures.

I'm pretty sure it's none of the 6 that you've marked. It's also possible I'm getting mixed up with my wife's 15" which I also repasted recently. Look under that cable, about where you wrote the 5. . It should be obvious when you see it.


Also - I don't think I've ever seen a 17" blade pro with an all black vapor chamber. Mine was mostly copper finish. Any idea when yours was built?

 

Ben95,

please could you have a look at my last post with a photo of the inside of the Razer Blade Pro and advise if there is a hidden screw under the cable near the hinges.

Thanks!

 

Yeah, my laptop was assembled on 01/2020 and I bought it about a month ago.

 

So, it means the laptop is quite a fresh one.

 

Hi guys,

I need your opinion on this matter. I have been in touch with razer support in terms of high CPU temperatures (90+). They asked me to download intel XTU and show them the statistics.
These were the results. It shows power limit throttling.

Results in balance mode under stress test:






Results in custom mode (CPU and GPU in high mode):



Is that normal to get this power limit throttling and negative max core frequency (sometimes after restart it shows positive value - system bug?).

When razer support team saw the results, they replied:



What is your opinion about this issue? Could you please check on your systems what the results are with intel XTU (takes a few minutes). I would like to find out if there is really a problem with my system or is it normal case among razer blade users.

 

Bump the Processor IccMax to 140-150Amps, it should go away.

 

That doesn't make any difference. I have tried different values (even with max setting) but still the result is the same - power limit throttling and current/EDP limit throttling.



Maybe there is really something wrong with the power supply. I ran this benchmark with CPU and GPU in high mode on razer synapse.

 

Sharing this video with the ones interested in a cooling pad. It includes several laptops, you can fast forward to the Blade Pro 2019, hope it helps.

 

Power limit throttling is 100% normal, expected laptop behavior. There is nothing wrong with your power supply.

On balanced mode, the CPU is limited to 35W. That's a power limit. When your CPU bumps into that power limit, it is "power limit throttling". Switching to custom mode in Synapse & setting CPU to high will increase the power limit a bit. Another impact of balanced mode is that it lightly throttles a bit at around 82C (down to 30W). That doesn't happen in custom mode.


Many of the settings you change in XTU have no impact on how the laptop performs, as it's not an overclockable chip & a lot of other settings are controlled by the laptop's embedded controller (EC).

As to why XTU showed a negative frequency - that's a question for Intel, but it is a software issue. There is no such thing as a negative frequency (think about it - it's not possible for something to happen negative times in a second).
