HP EliteBook 840 G8 overheating

[big_zygi]

I have a problem with my laptop, the CPU temperature reaches 100 C in idle mode.

if I set the battery performance to "best" it will overheat regardless of the power source (mains/battery)
I applied new thermal paste and there is no difference in the CPU temperature (when set to maximum performance) up to 100 C, when I set it to minimum it's about 50C

haw can i manualy set fan speed ?
or how can i reduce my laptop heat.

--------------------

Mam problem z laptopem, temperatura procesora w trybie spoczynku sięga 100°C. jeśli ustawię wydajność baterii na „najlepszą”, przegrzeje się ona niezależnie od źródła zasilania (sieć/akumulator) Nałożyłem nową pastę termoprzewodzącą i nie ma różnicy w temperaturze procesora (na maksymalnej wydajności) do 100°C, na minimalnej jest ok. 50°C jak mogę ręcznie ustawić prędkość wentylatora? lub jak mogę zmniejszyć ciepło mojego laptopa.

Its not a solution but help with overheating.

then we can set CPU to 60% and it temporary fix problem ...

Have you cleaned the dust from the fins on the CPU cooler and the intake and exhaust ports?

Yes, i clean all od that, add new thermal paste.

Furmark and CPU burner shows how quick CPU will reach 100 °c.

Only setting max CPU to 60% prevent CPU burning.

It sounds as if you did not quite do the removal and reapplication of thermal grease correctly, because what you described should not be happening. I am not judging. I know it does happen inadvertently.

Every time I have done a new application of Arctic Silver Ceramique2, my laptop and PC temps drop down after a few hours. 

What is the brand and type of thermal grease you used and how much did you apply?

Did you completely clean the top of the processor and the contact plate of the cooling plate that makes contact with the processor.

I use 99% Isopropyl alcohol and Kimtech wipes for cleaning off the old paste or  any remaining bit of of thermal pad just to make sure.

Did you perhaps use Liquid Metal?

I see that the region of the world that is showing is United states, but you typed in , my guess is the Polish language. If tha is accurate, the ambient temperature should be cool.
