What is the exact setting name? Do you have setup IFR generated already, or do you need me to send you copy of this so you can find the setting and let me know?

62

I do have IFR, but I do not know which settings to change.

63

You can set Active point 0 or 1 fan speeds, or change those active trip points temperature setting, so they are invoked at lower temps thus making fan speed up faster
Active Trip Point 0 = 71C
Active Trip Point 1 = 55C

However, I cannot tell for sure if this temp/profile/method is used, it may not be and EC FW may control your fans. Do you see active fan speeds change at those exact temp points?

64

Does not seem like it. There seems to be more then two trip point temps.

65

Yes, but those I mentioned are the ones tied to fan speeds in BIOS settings, IF this profile is being used. If fan speeds do not change at those temps, then fan speeds are EC FW controlled and we can’t adjust
Can you change with software, like MSI afterburner? If yes, then you may need to stick with that method.

66

Software like MSI Afterburner, Speedfan, and notebook fan control all don’t work.

Would changing any of these settings work?

67

Those are the ones I asked you about.

68

I mean we could try?

69

Yes we could try changing those, but you said 55C and 71C is not where fan speeds change, so this method is not being used so it would be waste of time to change them.
What exact fan speeds do you see at different temps, and what exact temp (as you can guess/check) do the fans change to different speeds. I will check the EC FW and see if I can find
If you want to also look, EC FW is the first padding inside the BIOS region, when viewed with UEFITool NE - Extract that padding and you have the EC FW to look through

70

I said 55C and 71C does not seem like when the fan speed changes because my laptop fans increase rpm very slowly. So I can’t really tell.

71

It would be noticeable change in RPM right near those exact temps, IF these settings were being used, I assume they are not.

Open CMD Prompt as admin and run this exe, or run the batch file, can you see and control fan speeds with this?

73

I just checked. My fans do start to turn on at around the 70~C mark and turn off at the 50~C mark. They just do it very slowly that’s why I didn’t notice at first.

74

@RogueDragon - Can you change fan speed with Fanview though? Check, use UP/Down (8/2 w/ numlock off, or Up/DWN arrows) and W/S, pay attention to the speeds they change easily a second later and it may not look like anything happens until you notice.
If that works, but does not change fan speed as checked with monitoring tools, then either this not compatible with your EC FW, or fans not EC FW controlled, hard to say.

We can try to change the 55/70C targets and see if you can then see the changes
Example -
Active Trip Point 0 >> Change from 70 >> To 55
Active Trip Point 1 >> Change from 55 >> To 31

This would turn your fans on sooner, and then maybe keep temps lower, especially if PWM is used and or voltage table increases after 55C reach as temps rise fans would get faster
If you want to do that, make the following changes in RU @ Setup

Active Trip Point 0, VarStoreInfo (VarOffset/VarName): 0x392 >> Change From 47 >> To >> 37
Active Trip Point 1, VarStoreInfo (VarOffset/VarName): 0x391 >> Change From 37 >> To >> 1F

75

@Lost_N_Bios - before we try that, do you know what rpm or percentage Active Trip Point 0 runs at? Because my laptop has at least three tri points. One for off, one for on slow, and one for fast. Trip Point 0 at 70C seems to be on slow.

76

@RogueDragon - No, I can’t see what any are set at other than what I mentioned before, and I’m not sure if these profiles are what is being used, can only go by what you tell me yes/no at those exact points or not.
Changing them will let you know for sure, if nothing happens, then this profile is not being used and EC FW is instead. Passive/off would be the third I’m not mentioning, because off=irrelevant here
It has to be turning on before 70C, you just don’t hear it maybe. Hold a string or hair in front of the out port, you will see it move long before 70C. Or open back of case and watch the fans.

77

Got it, thanks. I will change RU and let you know.

78

I changed RU and ran Cinebench, nothing has changed. I guess I just have a really stubborn laptop.

79

Yes, it’s common, many laptops use EC FW to control these things. If you have programmer, sorry I forget, you can dump EC FW chip maybe, and send to me. Then I can see if I can find, but no promises on that, there is no software that I know to view/edit, so it will be all blind hex poking around.
Or!! Maybe you can change the BIOS setting which tells the BIOS to use EC FW or BIOS setting, wait if you’re reading now I am looking in the settings to find for you

* Edit - Seems maybe SA Thermal Device may be what is being used here, so try changing these trip point offsets and see if trip points seem to change or not

@Lost_N_BIOS sorry, but could you tell me what exactly I need to change? Also, do I need to change 0x392 and 0x391 back to original?
