Which of the two programs is lying?

Question

linux

Conducted a stress test of the Core i9 9900k processor on two systems: Windows and Linux (Debian). On Windows, at 100% load, speedfan and Open Hardware Monitor show 69-72°. In Linux, under the same conditions, the lm-sensors program shows 89-90 °, while throttling is not observed. Which program is more likely to lie?

Answer 1

it is necessary to find out from which sensors the data is taken. in general, correct programs do not give gag. however, there is a high probability that different sensors are read
( upd and they are crazy, for example, in my desktop. personally, I have not yet been able to find exact analogues for the kubuntu widget and aida64 under take out10. but this does not prevent me from sleeping peacefully)
ps from the comments:
Igor Makhov ,

I just wanted to know if my build can be used for high performance tasks without fear of overheating the CPU or not.

and there are no tricks here:
- your processor has a spec - there is a TDP
parameter in the spec - and your cooler (even if it is a passive radiator or dropsy) has a TDP parameter - the TDP parameter of the cooling system should be equal to or higher than that of the processor (better when above) - do not use overclocking techniques .. if you follow all the points, you will be happy

Answer 2

I can tell you about real temperatures at 9900K.
Its heat output on the website is indicated as minimal! NOT THE MAXIMUM
It heats up like a kettle and a little more
The real way to cool the 9900K is just dropsy! moreover, 240, so that it already costs adequate money .
No cooler even rza 6K will cool it, well, the last and largest ones will cool it, but for the price it is more expensive than dropsy and the exhaust is less.
Gone are the days of waterless processors.
It's water time.
There is no other alternative.
If you are playing, you may have enough ordinary powerful coolers, if you make calculations, then no, any air cooler will not give you noticeable cooling.
It is in connection with such wild heat dissipation

Answer 3

The probe of a proven thermometer, thrust into the processor, will judge you.

Answer 4

Linux doesn't always show the temp correctly.
You can use it, nothing will burn.
All the same, the PC is oriented to the pace, which is shown in the BIOS. And it will cut out if it overheats.

Answer 5

Well, I would guess that in different systems there are different cooler control settings, so the temperature can really be. different.
As ky0 said above :

The probe of a proven thermometer, thrust into the processor, will judge you.
