Razer Blade 16 CPU temperature; what is normal?

I’ll just start this with, I’m usually a desktop user. A long story short I had to replace my desktop with a laptop. 

 

I’ve had a Blade16/4090 since the start of March but I just can’t get over the temperature. During gaming my GPU will sit around 70-80c but my CPU will sit around 95c-99c. 

Now I come from a desktop where I’ve used a custom water-cooling loop and never saw my CPU go above 50c so naturally these temperatures make me worried.

 

I’ve tried to undervolt it but that’s made zero difference to my temps. I haven’t yet took it apart to apply new thermal compound but I figured I shouldn’t need to do that on a £4400 laptop which I’ve only used for a few weeks. 

 

Any other Blade16 owners mind letting me know what sort of temperatures they’ve been getting and should I be worried?

Exact same issues, I’m monitoring temps with MSI afterburner, on the main menu screen on balanced or even low across both GPU and CPU temperatures are 87 to 90 degrees on the CPU, it doesn’t seem right, I also tried undervolting my keyboard is barely touchable.

Yah min​e was really hot. I’ve had to send it back as it has developed a fault with the screen but will be interesting to see if I get my original unit back or a replacement to see if the temps are the same ​​​​​​

Yeah, I get the same temp range here. If it's the Blade 16” 2023 model with the Intel Core i9-13950HX Processor and the RTX 4090 Mobile GPU, it seems to hit temps of 99oc CPU and 70-80 GPU on resource-heavy games. Quite honestly, given the size of the chassis and the location of some of the vents, I'm not surprised we're hitting those numbers.

It's a beautiful machine and for something that can run most games on ultra in 4k, that's also super portable, I think it's a case of compromise.

A lot of folk online suggest underclocking/undervolting but for a $4k+ laptop, I just plain refuse. 😅

I've never had issues with keyboard heat like others mention, though, so you might want to get that checked. The hottest (and untouchable) part of the laptop is the top 'bar' between the keyboard and the screen.

I’m on my second blade 16 because the first ran 107°C at spikes and averaged over 85°C. 
 

It’s clear to me that every razor blade 16 will suffer the same way yours and mine does because the chassis and cooling system cannot handle the heat generated by the CPU. 
 

I’m a computer engineer and repasted the CPU and GPU with PTM 7950 and it made no difference whatsoever. 
 

contrary to what you may think undervolting seems to cause it to run hotter because there’s more thermal headroom. 
 

the only way I found to get the system to run reasonably cool is to disable the boost in your windows Power plan. Then the CPU will run around 60°C. But unfortunately your performance will be Nerfed. 

Playing Call of Duty Modern Warfare 3 on Extreme at 4K and the CPU package hit 113C on my system. I was still getting 110-130 FPS.
