CPU Temperature Issue

[[email protected]]

Hello guys,

I received my new laptop today and I run a CPU stress test and the maxim temperature in less than 5 minutes was 97C, Should I return it?

On idle is at about 45-50C
If I do random staff in Windows is staying between 60-80C.

I read reviews on forums and at maximum load on all 6 cores should stay around 75C.

U have few options if u wanna take control that high temp.

- offset core voltage ( uv , xtu ) effective and boost your cpu core frequency
- lower short boost power limit, but this option lower your cpu clock speed on that 28 sec boost time (xtu) effective
- Cooling pad . Mostly works
- Repaste your cpu . ( Not recommended , if u don't know how to do it ) most effective if u use with uv.

With respect to @ExistedName , I wouldn't recommend tweaking the clock settings / over or underclocking your laptop if you're not familiar with what you're doing.

A cooling pad will certainly help and needs no prior experience!

I'm not certain what the temps should be, if they're over the top and you are not comfortable with repasting then I'd certainly suggest letting PCS know, perhaps all it needs is a repaste?

Easily can be push that temp down if undervolt that cpu ! XTU make it very simple .
Also need to take that gpu out of that stress test and we will see more accurate temperature !
8th and 9th gen CPUs in laptops running hot ( very hot ) that is the main reason why I have Octane VI . His laptop has disadvantage : slim design .
One of the reason why he has so high temp because extremely stressing the full system pointlessly . No any application put that much pressure on full system !

Cooling pad not even necessary if he doesn't want spend more money . All he has to do lift up the back end a bit with something so the laptop more easily can suck fresh air in .

This is a good point that stress tests don't necessarily reflect real world use. Laptops are notoriously difficult to cool and stressing one to its limits is almost certain to result in very hot running.

Personally I would invest in a fan assisted cooling pad before embarking on an undervolt experiment, as Steaky360 says you do need to be confident in what you're doing there.

Hi Guys,

Thank you for the suggestions.

I come with an update:

I'll not understand how this laptop passes the PCSpecialist tests, as with no stressing the CPU the temperature jump to 90 degrees C.

I'll run a stress CPU test again and update.

Cooling pad, I expect to get delivered one today see picture.

Hi again,

I did some more tests and I'm very disappointed.

Did some Benchmarking tests and all are at high temps. Eventually 100C. The Thermal Throttling is YES almost all the time. See picture attached. And all this with default settings. I don't think I can do anything to lower the temp.

Ok ...Let me help u !

1. Open XTU
2. Change Core Voltage offset to -0.050V ( first step , we will going lower . Normally the system can handle -0.120 ish )
3. Change Turbo Boost Short Power Max to 70W
4. Apply

Aida64 ... when u stress the cpu u have to stress CPU , FPU , CPU cache , and system memory too ! Install HWMonitor here

Do the test again . If your system stable we will change the Core Voltage Offset lower step by step . Nothing wrong can happen , trust me !

Here is my result ( My cpu desktop grade i7 9700 65W , running on 80W . Capable of handle 100W ! )

Hi,

Thank you for sharing this with me. I won't do any changes as I talk with them today and they ask me to return the laptop. It's been scheduled for Friday.

I'm sure will be impossible for me to get it stable as on standby (the time I wrote this respond), is 65-75C, at no stress at all. I read a lot about this processor so far, and the temperature should not go so high. I don't want to damage more if the paste was wrongly applied.

See picture again with my cooler pad at maximum.

 

[ExistedName]

Make sense . That 11W shouldn't rise the temperature that high .

Not sure if I can share a video of this processor review on youtube. But have a look at what this guy can do with this processor and see his temperature stability and then compare it with mine.

YouTube

Now compare them with mine ... I give up! Hope I can short this problem with these guys.

Yes u are right but every CPU are different !!! Each manufacture using different cooling system !!! Don't expect the same result from your system ! ( Can be that good , maybe you are a winner on silicon lottery )

Let's wait till u get it back . If u need any help for how to use XTU ( better than ThrottleStop ) u can contact me any time !

 

[steaky360]

Do let us know how you get on, will be good to understand what they think is going on here.

Happy New Year guys,

Finally, I received my laptop back. They replace my motherboard and link the heatsink corrected. I can see there is a good improvement but still have some concerns.

I tested in Game "This land is my land" with everything on Ultra performance. See picture attached. Want to mention that on the left side, is very hot, you cannot keep your hand on to use W, S, A, D, to long, it's like you want to keep your hand on a hot heater device.

I use a "cooler pad".

Is this normal? or still, is not something quite not right for this system? is anything that I can improve in terms of temperature?

My scope getting this laptop is to play games (news one) with no worrying of breaking it.

I tested on Heroes of the Storms and with high performance had no issue.

Thank you for your feedback.

It is a laptop so it will run hotter than a PC tower with a ton of airflow and fans, something you'll need to accept.
The 2nd screenshot with CPU usage of 39% and temps in high 80's is still a bit worrying in my opinion. Could potentially cause some serious thermal throttling if usage goes higher?
Contact PCS with screenshot and see what they say.

The CPU temps by themselves don't look too bad - sad as it is to say - for a modern laptop. mid-high 80s average with an occasional peak to ~90...

If the laptop becomes too hot for you to touch, that is a problem of course.

You could try undervolting the CPU. Undervolting is where you reduce the voltage to the CPU, as the CPU is often receiving more voltage than it needs by default, without reducing frequencies or harming performance. It can actually increase performance, though the main aim would be to lower temps.

Perhaps discuss with PCS again

For 40*% Usage high 80's is pretty bad. I'd understand 70% usage or 80% but not 40*%

Id definitely check with PCS don't settle for less when you paid a lot.

 

[Oussebon]

I saw that. Odd as it may sound temps don't always increase linearly with % load.

For instance if the fans aren't at full speed, because the CPU is not at max load. It would concern me too, but taken in isolation it's not necessarily unusual. Unfortunately.

I did a CPU stress test and the maxim was 83, but GPU was not used at all. I believe the GPU is on the left-hand side of the laptop and the temp for CPU go up because of the load of the GPU. Sound strange but, the right-hand side was not hot at all.

Is this forum a way to address directly with PCS?
