Cpu at max for some minutes

Hi all, :wave:

I´d just like to know your opinions about a certain matter.


I was using a tax programme originally written for WIN (of course) on my Linux system (Linux LIte 6.2) using playonlinux/WINE.
I had to do some configuration work in the settings of the tax programme first.

Well, the thing is: during the proccess the CPU Load suddenly got up to 100 %. Taking a look at my running conky showed me that. :face_with_open_eyes_and_hand_over_mouth:
But I didn´t notice it at once and when I noticed it the CPU was at 100 % for 2 to 3 minutes already, I guess. :roll_eyes:

Sure, the fan speed was going up as well but I didn´t notice it at once either as I had to put up with some other source of noise in the room at the time.

So I hope the CPU running at 100 % for some minutes hasn´t done anything bad to my computer (which BTW is a Lenovo H520e desktop model)… :question:

What´s your opinion on the matter, if I may ask?

Thanks a lot in advance for your views.

Many greetings from Rosika :slightly_smiling_face:

It won’t hurt. When I render something, the CPU works constantly above 90% sometimes for hours long. The worst that can happen is that your cooling is insufficient (maybe the sinks clogged with some dust), and the CPU begins throttling. That means it temporarily reduces the clock frequency to lower power dissipation, thus avoid damage caused by excess heat.


Good old Pentium 4 days:

AMD got much better meanwhile of course :grin:

@kovacslt, :slight_smile:

Thanks a lot, László, for your reply.

Phew, I´m glad. :relieved:

I was quite startled at first as something like that hadn´t happened before.
Still, it´s good to have an instance of conky running at all times, I guess.
I doubt I would´ve noticed what was going on otherwise… :blush:

Thanks for tellling us about your experience…
… and thanks also for the youtube link.

Hi Rosika,
Your Desktop has fan openings at the rear of the case.
Make sure they are not obstructed. Clean with a vacuum.

As @kovacslt says, 100% cpu is no problem in itself, but it will need to be properly cooled



Hi Neville, :wave:

Thanks so much for your answer as well.

Right, I made sure of that.
As I already mentioned I noticed the fan was whirring at a much higher rate. I guess cooling is o.k.

Thanks a lot and many greetings from Rosika :slightly_smiling_face:

My output of sensors:

laco@Nagygep:~$ sensors
Adapter: Virtual device
temp1:        +46.0°C  

Adapter: ACPI interface
temp1:        +27.8°C  (crit = +119.0°C)

Adapter: ISA adapter
Package id 0:  +73.0°C  (high = +82.0°C, crit = +100.0°C)
Core 0:        +68.0°C  (high = +82.0°C, crit = +100.0°C)
Core 1:        +73.0°C  (high = +82.0°C, crit = +100.0°C)
Core 2:        +67.0°C  (high = +82.0°C, crit = +100.0°C)
Core 3:        +69.0°C  (high = +82.0°C, crit = +100.0°C)
Core 4:        +69.0°C  (high = +82.0°C, crit = +100.0°C)
Core 5:        +69.0°C  (high = +82.0°C, crit = +100.0°C)

Adapter: PCI adapter
Composite:    +36.9°C  (low  = -273.1°C, high = +80.8°C)
                       (crit = +81.8°C)
Sensor 1:     +36.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +47.9°C  (low  = -273.1°C, high = +65261.8°C)

CPU worked (and is still working) around 80% for the last 15 minutes.
All I want to say, using sensors you can make a good guess wether cooling is OK.


Hi László, :wave:

thanks a lot.

With me it looks like this at the moment:
(Of course I´m not maxing out the CPU right now, it varies, but conky says 2 - 8 %):

Adapter: ISA adapter

fan2:        1544 RPM  (min =   46 RPM)

Adapter: ACPI interface
temp1:        +27.8°C  (crit = +92.0°C)
temp2:        +29.8°C  (crit = +92.0°C)

Adapter: ISA adapter
Package id 0:  +33.0°C  (high = +87.0°C, crit = +91.0°C)
Core 0:        +33.0°C  (high = +87.0°C, crit = +91.0°C)
Core 1:        +30.0°C  (high = +87.0°C, crit = +91.0°C)
