NO MORE THROTTLE OR FANS surface pro 3/4

[Geo Hutchings]

1) Click start and type "regedit" (no quotes) to open the "Registry Editor"
2) Navigate to HKEYLM\SYSTEM\CurrentControlSet\Control\Power
3) Change the value of "CSEnabled" from 1 to 0.
4) Click OK, exit the registry editor & reboot.
5) Log back in and check your Power Options, you should have all of the hidden Power Themes & advanced options.

*Maximum processor state settings will modify the throttling settings.










Now reboot!!!






Clock to what works for you and merry Christmas

The screenshots are a little compressed so some parts are hard to read, so here's some easier to read instructions:

1) Click start and type "regedit" (no quotes) to open the "Registry Editor"
2) Navigate to HKEYLM\SYSTEM\CurrentControlSet\Control\Power
3) Change the value of "CSEnabled" from 1 to 0.

Just notice only look now, as I had to wait for it to be allowed I will write it in a bit cheers

I'm hoping you don't catch a bunch of grief for posting a solution.

But I suspect

Also more battery

 

[zkyevolved]

Also more battery

How so? Supposedly this will give you longer battery life? But... won't this overheat your device if you turn off the fans? :S

You are not turning off the fans XD lol you are under clocking it to the point that it is running at 45-60c but still giving you a really fast machine and stop it trying to push and more battery as its using less power

Ahh OK, I understand now. But my question is why would you set the minimum state to 50% when on battery, and 35% when plugged in? Is that to keep the processor cooler while the device gets warmer while charging?

correct

 

[zkyevolved]

correct

And you're not getting any slowdowns for running the processor at half speed?

 

[Geo Hutchings]

Nope... like maybe running games, but then I just put it to 75%, its funny the i5 and i7 run better at low speeds, in the surface pro's anyway as they run cooler

Already made this change a couple of weeks ago. However, the cpu speed isn't throttled down to max 50% or 35% , and still goes up to 100% on my i5. I'm not sure if these settings do anything at all, fan still comes on when watching on line HD videos etc. Also, i run BatteryBar Pro which can show the power drawn by the CPU, this still goes up to 25W at times.

Update 28/12: i take that back. I made these changes again, and CPU-Z shows indeed that cpu is throttled to the max percentage set. Even better, you can undo the registry change to get the sleep state back, and still use the power scheme you created with the advanced options.

Download throttle stop 7 I think.. and disable turbo boost but you should not have to do that... you might have to get a replacement

No slow done and no fans.. at the last point the tablet was not even warm.. felt like a IED light would feel little bit colder then that

Okay now I have put in my dock. on battery
This so I can utilise my 32 ich 1080p curved display, keyboard and mouse and speakers, when rendering/setting up
I have keyshot, egde, modo and 8tracts for music running at 1.4ghz stable, no fans and only warm to the touch, rendering took 6mins on a 3k res image 44k triangles in the model, keyshot was running at 24fps

Lol what you on about XD

This works. You can even change back the registry setting to get the sleep-state back, and still use power schemes created with reduced cpu settings.

I find it odd that they don't allow the settings in the first place...

Glad to hear

That's definitely a good trick to get a silent, cold, powerful "tablet", that can be unleashed at any time...
In order to play 5+ years old games, fanless, I'm also using the following tricks :
- Custom resolutions (reg files)
- Frame per second limiter to 30 fps (I'm using dxtory)

For instance with a SP4 i7, I'm able to play "The Witcher", the first one, at 1728x1152 (roughly equivalent to 1080p), high quality settings in the game, limiting at 30 fps, with the fan stopped.

Using a soft like Dxtory just to limit the fps is a bit strange, if someone knows another way, I'm interested...

Thank you for creating this thread, for now it gives good indications that it will help me save a lot of battery.

I just have one question about your settings: If you are setting the minimum processor state on 50% and 35%, doesn't that mean you are making your processor run more than it should? My confusion comes from the fact that by default the minimum percentage on both is 5%. It would make more sense to change only the maximum processor state.
