CPU Overheating, Is It Normal?

[Isaac Foster]

I have an Intel® Core™ i5-8300H from 2018, 45W TDP. On the GPU side there is an NVIDIA GeForce GTX 1050. 4GB VRAM GDDR5.
Here is the problem, the CPU is Overheating. The GPU is 20C Lower than the CPU.

CPU 90C.
GPU 69C.

This, is sh*t, I am getting around 80 FPS+ at FH4 High Settings (Yes it's the same FPS as the GTX 1050 Ti Desktop Ver.) But as an gamer, I want Maximum Performance out of the things that I buy.

The GPU and CPU use the same Thermal Paste. But significant temp difference, why is this happening?

 

My Milestone : get 90-100 FPS at FH4 at high settings.

Right now, the CPU is outputting 20W because it's HOT.

so my Milestone might be possible if the CPU is fine.

Shit cooling, typical for laptops. Is it normal? I would say it is. Is 90c overheating? nope. You still have around 10c before it starts throttling. There is also the difficulty of having to cool 120-150w of components in a laptop that isnt as thick as a brick.

The wattage limitation on the CPU may have more to do with the available power than the thermals. For example, if the power delivery can only give 125W, and the GPU pulls 75W, that only leaves 50W for everything else (CPU, display, drives, RAM, etc) so the CPU will have to draw less power so the rest of the system can function.

 

Have you tried to see what sort of performance you can get when the cooling is better? Like with a cooling pad, or elevating it off the table to give the fans more breathing room?

Despite claims laptop overheating is an issue due to space limitations  the thing is most programms use CPU more then GPU.

That too, but thermals do play a role in unlocking higher clock speeds on newer machines, so dropping temps would increase perfomance.

 

But really i am not a fan of gaming laptop industry, too many compromises for marginal usability

Yes, thermals do play a role, which is why I said to test that. But no, there is no guarantee that better thermals will help, which is why I said to test that.

 

If you are 100% power constrained, thermal improvements do nothing. Also, plenty of older Intel CPUs have basic boosting behavior that only cares about thermals once you hit the defined limit. And with laptops, the OEM has tons of control, meaning that unless you have the exact same model to test, you cannot say "the 8300H does a soft throttle staring at 80C" because that will not be universally true.

Ofc ofc

Absolutely, but taking it into account is a valuable tactic to adress the issue.

 

Just sounds weird the laptop would be power constrained from the factory, but again laptops are not my major)

That's totally normal. Don't forget that battery life is a big selling point, so stock settings are going to be more power limited.

 

And lower power limits makes the whole laptop cheaper. Cheaper power brick, cheaper VRMs, cheaper cooling solution, etc all adds up to better margins. The laptop will sell just fine, because 95% of consumers don't even know what a configurable TDP is, much less what lowering it does to performance. They see "i7" and just assume it's powerful.

Ah, i see i see

Most don't need to in all honesty

Anything to improve the thermals? Well I tried Undervolt and ASUS BIOS team are just like "let's lock the voltage for no reason" I will try Liquid Thermal soon. I remember trying extreme cooling solution by adding 1 more fan. It worked, 28C Idle Temp, and if I unlock the TDP it will go 65W all day. Sadly I can't keep the "Extreme Cooling Solution" People buy laptops because they can just put it in a bag and bring it everywhere they want, and the Extreme Cooling Solution is too thick lmfao. But I will try my hardest to keep the CPU cool and chill, really, nothing is impossible in this world, at least that's what my dad said.

 Here is the thermals. 

So far everything is normal. GPU is literally almost 2GHz there and still at 55C

But look at the CPU, 67C, Now that's a great temps, but, The TDP is low, 20W/45W

and its dropping performance significantly.

The Usage? Well they are low because the game are running in the background 

for some reason my Snip & Sketch doesn't work with Windows + Shift + S lol
