How reliable are the power delivery in laptops

[helix26]

Hello all, 

I run a ASUS ROG Strix SCAR III (i7 9750H with RTX 2070 configuration), and I use it for training deep learning models. All the models train for at least 8 hours and the average temperatures of the CPU and GPU are around 90C and 65-70C respectively. The Power draw of the GPU fluctuates between 80-110W and needless to say, the charger is plugged in throughout. I am concerenced about the life of the components especially the CPU(due to high sustained temperature) and the power delivery component in laptop.  Is it safe to continue such use and what would be the impact on life? 
TIA..

Just the nature of the beast. Pretty normal.

They just run stupid hot. Like a desktop shoved in a 1/2" thick case lol.

 

It comes with a warranty.

Just like back when I had free electricity for folding, I prefer keeping the CPU away from computing workloads when it runs so hot. Dont need to worry about the VRM tho since laptops are designed to run at their thermal throttle points (if they do reach them) or max performance.

Thanks a lot for the reply, I wanted to know how adverse is the effect on life, If it goes bad outside warranty

Most power supplies are rated 100,000 hours continuous usage. 

The battery "should" be the first component to go bad. 

When happens, get a new asap, cause the bad battery will take out the charger.

@Jurrunio Thank you for the reply, so are the CPU temps a mojor concern, or is it okay to let it linger around 90 degree celsius for around 6-8 hours, the critical temps for the cpu is 100C

the throttle point is at 100c for a reason lol. 90C is very hot but shouldnt have extremely adverse effects on your components. if it spikes higher than 90c i'd maybe undervolt a little but 80-90C shouldnt be cause for worry. assuming youre running it completely stock, no reason to think its abnormally dangerous

[helix26]

@VeganJoy yes it is completely stock, the temperatures do reach around 95 and stay there for some time, Thanks a lot for the reply, tbh I really get uncomfortable when the temps are that high, this with a cooling pad beneath.

95C is definitely pushing it. not worried as much about the cpu as id be about the surrounding components like the memory. undervolting is pretty straightforward, would help temps a lot. a repaste could be an option, plus sticking some thermal pads on hot points to help distribute heat. people who are serious about laptop temps use liquid metal and expensive fujipoly pads but some normal paste like tg kryonaut or arctic mx4 and some basic 7w/mk pads would be a good jump over stock. chances are that someone on youtube has a teardown of this laptop or a similar model and has pointed out good spots to put thermal pads on.

Thanks a lot @VeganJoy will try these solutions out.

Capacitors really dont like heat, that's why I would avoid running it so hot long term. The CPU itself and many other components don't care about running on the limit however.

Pretty sure most caps can handle over 100c Jurrunio

you should also consider the performance, for machine learning CPUs are really slow compared to GPUs. Why let it nibble my capacitors lifespan when it barely speeds things up (in percentage).

lifespan of most solid capacitors is 200,000 hours.

Coils are 100,000 hours might be more or less depending on gauge and amount of windings. 

 

Now chemical capacitors generally don't like heat and have a lower lifespan. Gotta watch that on buying used classic and vintage hardware for sure.

GPUs are indeed way faster, but you need to remember that more often than not some data transformation is needed before the GPU can use it to train, which seems to be the case with OP since both CPU and GPU are being stressed out.

Yes this is the case, and also the CPU is the one responsible for loading batches and scheduling the GPU, so even if there is no dataprep, the CPU will be used to certain usage, and exactly what operations are  performed by deep learning frameworks in the background we dont know that either.
