Why Ubuntu and Windows download CPU different?

The laptop has 2 operating systems: Windows 10 and Ubuntu.
Just noticed that on the Ubuntu laptop starts to make noise after starting (the noise in my case, the indicator that is loaded PERC) and the battery time is less than 2 times. In system monitor I look: on simple 70% consistently.
On Windows it makes a noise always justified, "in the case" (when compiling the program, either boys Oh boys tabs and apps open).
On Ubuntu for learning purposes. What could be the reason? Here it is not even in the figures of the CPU, namely the work at a laptop - a basic discomfort occurs.

in order to "calm the water cooler" you need to put/to set
why do you have the CPU loaded at 70% ??? - see in system monitor that seems useful.
and if is Windows 8.1 Pro on the laptop. it is possible for example to set so the cooler on percents is included at 70 degrees. I tried to put the program speedfan but it doesn't work. helps to set the energy saving mode to maximum then the cooler runs constantly at 50-55 degrees CPU. in the BIOS was looking for the temperature - there is no point which would lead to it. laptop msi ge62 2qf. percents i7 5700hq dbylf 8.1 - Anya_Hodkiewic commented on April 19th 20 at 12:07

What exactly is the system load?

Linux extremely miserable subsystem power management, then either the aggressive power saving on (Google: cpufreq) or to return to a full OS for the desktop that will support the laptop normally.

You can put aggressive power saving utility:
sudo apt install tlp && sudo tlp start

energy is what?

Because the optimization is different. Manufacturers of equipment/drivers to pay more attention to a more common OS, which is logical. In Linux, because of the large number of distributions have difficulty with optimization for each. So it all falls on the shoulders of the maintainer or the user. Some drivers so it says not a manufacturer, and members of the community.
So out of the box Linux on specific hardware runs more "wasteful" in terms of batteries. But if it "sleek" (to optimize), it will work about as Windows.
If you're lucky. And if not you can see in the dmesg a bunch of messages about not found devices and you will have problems with food. - rusty commented on April 19th 20 at 12:15

I have the same vin10 and Ubuntu. On the Ubuntu nagruzhennosti percent 5-15%. Something You seems useful. I think it's not in Ubuntu. See what process loads and deal with it. I CoreDuo laptop 2007. Ubuntu compared to Windows on a subjective opinion is more bright in 2 times.
Already it became interesting..Ubuntu, what version? Screw - HDD or SSD? - Boyd_Gutma commented on April 19th 20 at 12:17

So it is necessary to find out the reasons why it's loading so much. Be such a not be. Eliminate the root cause (load percent), there is the valve you see will cease to spin like crazy.

Once again confirmed that the Linux - system for zapilivanija. The number of laptops and their performance has long made up for their cost, and Linux are all treading water until now.
But I identically on Linux sitting: 3 laptop energy saving normal

Who Ubuntu put??? I'm currently on the laptop is supplied Mini cinnamonum everything works perfectly, the cooler on only when full load... And power management normally, when running on battery, the brightness dims, etc...
