SF314-42 How to make it quiet as a premium one

Hello,

This notebook is awesome, it comes with fastest AMD Ryzen APU's and has all the goods. But one thing was bothering me from time to time. When a computer receives a stronger load on CPU - fan becomes really loud, even if the load is very short.

There is a really good workaround to forget how the fan spins. You just have to limit CPU usage to 70%. A little loss of power, but a very satisfying use of laptop and of course, longer work on the battery.

1. Go to Start

2. Enter "Edit power plan" or "Power options",

3. Change advanced power settings

4. Processor power management

5. Maximum processor state

6. Set it to 70%

Okay, so there's a better workaround I've been using for this summer. And I didn't hear the fan spin. And basically couldn't feel any performance lose.

CPU turbo boost works by temporarily overclocking itself to max clock until it reaches critical temperature and fans needs to kick in at full speed to cool it down.

Theoretically it's a great function. Pratically it does it all the time when there's even a simple app launch. If you have a desktop computer, mostly you don't care about fans spinning when you're playing a game or listening o music. But when you're in cafeteria, drinking coffee and working with your ultrabook, you really want to keep it quiet.

By disabling turbo boost on my ultrabook I couldn't hear my fans spinning up and I didn't felt any performance lose.

You can do it by fallowing these instructions that some YouTube content creator provided. It works with Windows 11, it should work with Windows 10 also. :)

1) Open Advanced power option with "Win + R" and "powercfg.cpl" command

2) Find "Change plan settings" and "Change Advanced Power Settings"

3) In Power Options window find "Processor Power Management"

4) Under it find "Processor performance boost mode"

5) Put setting to "Disabled".

6) Done,

If option is not there - change registry settings:

1) Open Registry "Win + R" and "regedit" command

2) Follow the path: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7

3) Change option under name "Attributes" from "1" to "0". * If this does not work - try changing it to "2".

4) Close all windows and reopen Power options once again!

Hi @kirmgrauza,

Is the fan sound is very loud and is that records on a video recording? Also please share the exact model of the unit. Example SF315-52-58VH.

Yeah it does sound loud when when CPU usage is high. But I made this tutorial as a workaround how to solve it. Model is N19C4.

So instead of letting the fan spin up to full speed when the processor is working heavily, you just tell it to not run the processor at full speed.

That works, I suppose, but you are leaving a lot of computing power on the floor...

Yeah, I kinda thought of that. But these notebooks comes with powerful 4 generation AMD APU's and there's enough juice for any work task. Unless you go for gaming...

You might do some testing at 99% instead of 70%... A lot of the gamers swear by that.
