HP 255 G9

Greetings. 

A few days ago I bought a HP 255 G9 laptop with a Ryzen 3 5425u processor.

The fan on the laptop only turns on when the processor temperature reaches approximately 80c, spikes to almost 90c and only then does the fan manage to bring it down to normal, and so on in a circle. Why does the fan not respond before the temperature reaches the dangerous margin? Computer is so hot that you can't hold your hand from underneath.

The cooling fan is working as it should and is triggered at the Delta T in the BIOS ROM file.

80-90 Deg C  is not in the danger zone. As long as it never gets above 95C, it is a happy device.

You might consider using a laptop stand to increase the airflow.

You can optionally turn the fan to the "always on" setting in BIOS if that is your preference.

Hello Erico, thanks for your time and willingness to help.

First of all, the junction temperature on this processor is 95c, so everything above 90c is highly dangerous and greatly reduces the lifespan of the processor. 

Another important thing is that the surrounding electronic components, such as ram memory, nvme disk, capacitors, suffer additional heating due to such a high temperature of the processor. Such a high temperature must have an extremely negative effect on them. The motherboard and the plastic housing, which is extremely weak, also heats up a lot, and as a result, additional twisting occurs, which results in a greater twisting of the motherboard and leads to the risk of a wire bursting.

All of this would be less important (by no means negligible) if this laptop was not made of such low-quality materials.

A new bios with much more aggressive fan engagement is definitely needed here.

And yes, I set the fan always on, although it does not prevent the processor from reaching 90c, because the fan simply reacts too late.

I am extremely disappointed with the HP policy, the build quality is at the lowest possible level, when I lift  laptop fan sound changes due to case twisting.
