Windows 8.1 is supposed to be a bug-free operating system that shouldn't cause too many problems problems in their operation. At least, it won't be as much if you're moving to 8.1 from Windows 8.
It turns out, however, that many of the users who decided to do the movement to Windows 8.1 really experience all sorts of themes, including the highest flat noise generated by the processor fan.
Consumers clashed with Microsoft community forums to report that the fan the CPU produces more noise than before, probably in an attempt to cool the processor.
This means that Windows 8.1 actually requires more processing power, hence a warming need for more intense cooling.
Specifically, a user says in the Microsoft forum:
"My laptop is a Sony VAIO with a technological age of less than a year. I'm referring to the sound of the fan, which I had no problem with before updating from Windows 8. I called Sony and they told me to contact Microsoft. I noticed that my laptop was very hot on the side where the sound of the fan was coming from.
I don't work my laptop on a flat surface, I usually use a small piece of wood on the back to give it a 30 degree angle. The fan stops if I restart the laptop, and two minutes later, it starts working again at full power. When I explained all this to SONY they told me to contact Microsoft immediately as there is nothing wrong with machine. "
There does not seem to be a solution to the whole issue, as there is not much that can be done as Windows 8.1 requires more processing power.
Here are the system requirements of Windows 8.1 system requirements in case you want to see if your computer has what it takes to run the new operating system:
Processor: 1 gigahertz (GHz) or faster with PAE, NX, and SSE2 support (more information)
Memory: 1 gigabytes (GB) (32-bit) or 2 GB (64-bit)
Free hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
