CPU Heating and Performance Issues

[north fulcrum]

Model: Legion 5 16irx9
Describe the issue: Even Though my earlier CPU problems were addressed, i still like to have a few of my queries answered, The CPU seems to be reaching extreme temps and even underperforming in Cinebench23
What have you tried already?: I have tried elevating the laptop for proper airflow and avoiding it from hot environment.
When did it start producing the issue: I started running the monitoring and benchmarks lately and the laptop is relatively new, about 2 months.
Did you install new drivers or software?: All my updates have been from vantage
Can you provide images/videos to show us the issue: I will share a couple of my HW64info logs.

This is the Log when running Fortnite at,
1080p
Performance Mode on Lenovo Vantage
Performance graphics in fortnite
FPS CAP was set to 240

and This is the log of Cinebench23 on performance mode enabled in Lenovo Vantage
And from the screenshot you van also see the Cinebench23 results where the cpu seems to be underperforming getting only 25k.

I have provided multiple logs so it would be easier to determine the problem and issue

Undervolt the cpu, clean your fans and vents, lower your room temperature, repaste.

You only have a legion 5, you can’t expect vapor chamber type cooling for your cpu

[north fulcrum]

understood
what makes me thing there actually is a problem is when i saw the laptop i had getting around 80-90 degrees

when im getting 10 degrees more

the laptop is just 2 months so i don't thinkt the fans can be dirty especially when im cleaning the table i put it in regularly and maybe repasting could be an issue but its js 2 months

[mossy topaz]

None of this means anything

What I said are the things you can do. Nothing to troubleshoot

[north fulcrum]

what do the logs of HW64info say, if you've looked at it

[mossy topaz]

I’m on mobile, I’m not going to try and read those

[north fulcrum]

understood.

[mossy topaz]

What’s the average temp in fortnight

[north fulcrum]

above 90

maybe 94-96

[mossy topaz]

Not necessarily a problem

[north fulcrum]

ofc fortnite isnt optimized well but i seen the laptop as me get 80-90 so yeah

[mossy topaz]

What’s the room temp?

[north fulcrum]

it 16-20 i would say degree celsius

or maybe around mid 20s

[mossy topaz]

You should stop comparing to other people. They have the exact same setup as you? Same room temp? Same cleanliness of fans and vents?

[north fulcrum]

i understand what you're tryna say
but my laptop is relatively clean and new so vents and fans could be an exception

[mossy topaz]

Have you actually looked at the fans and vents?

[north fulcrum]

yes

[mossy topaz]

Pics?

[north fulcrum]

ill send the pics as soon as i can but im sure they're clean, i even have those light brush clean the vents

[mossy topaz]

That just pushes dust into the vents

[north fulcrum]

no i do it in slant and with the laptop above me having my sister/dad to catch it

trust me man, i've taken care of this laptop for more than anything literally

[mossy topaz]

How did you clean the vents?

[north fulcrum]

oh wait i thought fans and vents are same thign mb

i do that for the fans

[mossy topaz]

The fan blades are to bring air in

The air then goes out the vents

You can’t clean those with a brush

[north fulcrum]

the vents where hot air come out, its been clean

yes i got cinfused

the vents are rather clean + i occasioanlly have the air purifier one

[mossy topaz]

If your fans were dirty, then your vents were dirty

[north fulcrum]

the fans aren't necessarily dirty man, i clean it regularly

even tho they might not look dirty i clena it anyways, same as i brush my teeth

[mossy topaz]

Well you say you are cleaning them and doing stuff to catch the falling dust, which would imply there is dust there to begin with

[north fulcrum]

its like minimal dust, nothing like that u see on yourube

its barely 2 months old

i'm worried the cpu is a defect or that the thermal pase isnt applied enough

[mossy topaz]

It being 2 months old doesn’t mean much. People can completely clog their vents in 1 month

There is no defect

[north fulcrum]

actually let me send a pic bro

i can send a pic of the vents to u

[mossy topaz]

Sure, but it doesn’t really change anything

What I said in the very beginning are the things to do

[north fulcrum]

Here’s the vents

and are the temps concerning?

[mossy topaz]

These pictures don’t show anything. It’s just black

You have to shine a light into the fans so you can see in the vents

[mossy topaz]

You’ve been told no by many people at this point

[mellow bobcat]

the machine is flat with desk?

[north fulcrum]

no its an encyclopedia

and then its elevating

the fans have space to take the air in

[mellow bobcat]

nothing to discuss until you do something that was told to you

[north fulcrum]

no but the 90s are

[north fulcrum]

i did

i sent the files

[mossy topaz]

No. They. Aren’t.

[north fulcrum]

and what else have i not done

[mellow bobcat]

you undervolted?

you cleaned the fans?

[north fulcrum]

so 90-100 temps aren't concerning, i can go like hours on those temps???

[mossy topaz]

24/7 for years. The chip doesn’t care man

[north fulcrum]

last thread one of the guys literally told me to not do anything w/ it bc it was 2 months old
the fans are clean

i put my hands below the laptop fans, it sliterally freezing

[north fulcrum]

so the cpu doens't get damaged

[mellow bobcat]

my man

[mossy topaz]

How many times do I have to say no?

[mellow bobcat]

people tell you to do undervolt

"consider undervolting"

[mossy topaz]

You’re beginning to become very frustrating to deal with.

[north fulcrum]

im sorry, i get that the temps are normal

i will try and undervolt it

and the logs i've shared, i'd like to get a review on those if possible, if someone reads it ofc
and is undervolthign just hit and trial?

[wise lava]

Lenovo define limits that should not normally allow the laptop to be damaged within the warranty period regardless of what you do. If you want to be paranoid about longevity well past the warranty period you might want to look into peak voltages, not obsess over normal temps in the 90C range. If longevity is the goal: undervolt and perhaps consider decreasing peak multiplier from 58 to 54. Past that you could perhaps also have a look at using a newer microcode https://www.techpowerup.com/forums/threads/intel-how-to-update-your-microcode-for-intel-hx-13-14th-gen-cpus-laptops-mobile-easily.325403/ )

I did have a look at your logs previously. As far as I can see nothing have changed which make it relevant to have a look at further logs? You had a load close to design limit while the cooling seemed to function as expected. No issue.

[north fulcrum]

Thank you alot
I understand that it’s normal
also what do you think about it getting just 25k on cinebench r23?

I don’t think it was throttling during the process

[wise lava]

What do you compare against? I assume you are aware of the difference between single runs and 10min runs. Due to "long term" and "short term" power limits the score between long and short runs will differ greatly at default settings regardless of cooling. Neither can you compare against anyone who undervolt (which most here do) as that will greatly improve the score. Your background applications and minor stuff like moving the mouse also impact the score.

I personally believe you would be better served by spending your time looking into undervolting rather than pursuing this any further.

[north fulcrum]

So all I need is undervolting???

And thermal repaste is not an option?

[wise lava]

Please research undervolting. It's not expected to decrease temps during an R23 benchmark as long as you have the same wattage limits in place. You will however get better performance.

I have not seen anything that indicate thermal repaste being necessary. If looking into that the temperature delta between cores is more relevant than peak temperatures. While doing a R23 run with identical load on all cores you don't want the maximum temp difference between core of each type much larger than lets say 10C.

...and I never noticed any information of you cleaning out the heatsink with pressurized air after being asked about it. You only mentioned cleaning fans.

[north fulcrum]

The fans appear to be cleaner

[wise lava]

Cleaner than previously? Cleaner than the heatsink? What do you mean? Considering the fact that you mention it necessary to clean dust from the fans there is probably dust which should be removed from within the heatsink as well.

[north fulcrum]

wdym bt heatsink

ill send a pic when i can

[north fulcrum]

All in conclusion my laptop is running perfectly fine???

[mellow bobcat]

okay, so we can close this topic?

[north fulcrum]

one last thing ebfore closing

i think when i press FN + Q to get performance mode

it doesn't perform like before

like the fans are not comparatively loud as they sued to be

idk why the custom mode on best performance mode on power w/ fans full performs way better
