NO MORE THROTTLE OR FANS surface pro 3/4

[Geo Hutchings]

My main concern is why is there heat when this is what I'm doing:View attachment 119992
Ordering food on delivery.com, nothing else in the background, have modified host file, and the fan is on full!

Download throttle stop. And check the temps

That's a bit difficult to say something's just from this taskmanager capture.
I'm using Intel Extreme Tuning Utility to monitor what's happening tracking "package temperature", "cpu utilisation", "core frequency", "graphic voltage", and the more important, "package tdp".
Unplugged, without cover, in a 20?C room, the fan is starting at low speed after a few minutes at 8-10 watts. I never reach that in regular desktop usage, with rare exceptions being sometimes bugged applications stupidly deciding to eat cpu for something I don't care (things like cortana, windows update, one drive...).

But with a cover and/or plugged with battery loading that's probably another story...

Geo Hutchings, thanks for posting the regedit settings to get to the expanded power options window. I haven't actually changed my maximum processor state setting yet, but it's nice to see that I can do so at any time now. I still don't understand why you would change the minimum processor state from 5% to 50%. Since I don't have a fan or heat issue now, I think I'm just going to set my maximum processor to 65% from 100%. Thanks again!

Here you go:

fan near full, wtf is it doing?!

I was playing Zynga poker (only other app was Intel Extreme Tuning Utility) and the processor averaged below 15%. You telling me, with heatpipe, an i7 requires a fan for this very simple windows store app?!

PLEASE, anyone with a stock SP4-i7 that plays poker (ha!) just launch that app and tell me if the fans start going while playing. Will exchange my lemon tomorrow if not!

Zynga Poker takes up 3 GB??? Don't tell bolt about that. Something is up with your system.

That sounds weird, can you post the 10 minutes graph you can get with this tool ? (sorry I get the i7 but I can't connect to zynga poker)

Get it replaced... sounds like a problem in your system

Performance = heat, if you unthrottled the cpu it will get equally hot, there is no magic bullet setting that can give you the same performance for much lower heat. The only option that helps is voltage which you can drop to help until it becomes unstable.

So all this talk about max processor tweaks and not throttling is NOT reducing heat and putting more heat into the system without the fan.

Skylake is already designed to be very efficient leave it alone to do its job otherwise unintended consequences will surface such as added system heat in a thin chassis. Microsoft would have designed the surface without a fan IF it made sense for the cpu chosen.

 

[snakebitten]

He's right about the Skylake design. However, that "design" is far from leveraged properly and completely yet. (By anybody, as far as I know. Not Dell, HP, Microsoft, .... Simply hasn't been enough time)

Thus this thread.
None of us are saying these tweaks are permanent.

Comparison of 2 minutes of the same scene of a game, with the cpu set first to full then limited (as suggested in this thread).
Full CPU values:



Limited CPU values:


I think it demontrates that the fan is not or less running only because there is less heat to dissipate.
I would say that the tweak suggested in this thread is actually good for the hardware.

How can you draw that conclusion? The graphs are near identical.

Sorry, I have now edited the images with labels to be more understandable.
The images are the same, except for the white cursor and the associated values.

Thanks... so by your graph its 48C vs 45C or 118.4 F vs 113 F

Now the FAN will expel all that hot.

So on a hot day which would you rather have:

Option A In a tool shed 118 degrees with a fan drawing hot air outside
Option B In a tool shed 113 degrees without a fan no air flow

Both temps are within range for the CPU what none of you are taking into account is the built up trapped heat on all other components inside the surface itself.

 

[ajay singh supahiya]

I had the same confusion. But with what I understood I will try to explain with your example. In option B i.e 113 degrees, it is not fan less. Fans are just less running for obvious reasons. So basically we are just making an i7 to work like an i5 and produce less heat.

By manually setting OS cpu limits all of the cpus automatic "speed step" is turned off.... the surface was purposely designed to use skylake speed step and that effects when fan runs...its not some thermostat threshold. Its controlled in the cpu architecture.

This is back open now, please be respectful and Keep on topic, I be glad to help anyone out

 

[snakebitten]

Thanks Geo, in case I haven't said so before. Your efforts are greatly appreciated.
And my SP4 is a 99% delight to use. Daily, in fact.

 

[KristianKennethCarl]

On Minimum Processor State, I have 5% on both on default. Is this normal?

 

[tboy2000]

If you have to slow down the cpu to avoid fan noise then what was the point of buying an intel surface pro when you might as well have bought an M3 version?
