New Fan Control DSDT - for silent fan at higher temps!

Hello Rehabman,

do you think I will be able to control my fan with your program on my laptop HP 250 G2, Intel Core i3 3110M 2,4 Ghz, Intel HD Graphics 4000 ? I am trying to find some solutions to have it more silent ... I can see that the fan turns on if reaches something between 47 - 50 C and then cools down under 44 - 42 C, I don't know exactly ... What I can see it's tested mainly on Probooks, but mine is different model ...

It is unlikely. The only way to see would be to see if the fan control registers are present at the same locations in DSDT, and that they respond the same way when manipulated in RW-Everything on Windows.
 
Hey RM,

Was wondering if you have ever had your fan just pin to 100% and then not shut off or ramp back down until a reboot?

It has happened a few times randomly. Not stressing the cpu too much (temps around 60-65C) then it just ramps up even though my temps have fallen way below the shutoff threshold.

No. Never.

Hi RM,

So it looks like this fan pinned on 100% issue is happening very often now and I can't figure out what is going on. I've tried a clean install on both Lion and Mavs, fresh new DSDT's on both and it still happens.

I was wondering if you know of a way to see what temp values are sent to the EC? or what values the EC is seeing?

Since it seems like an isolated case, I was hoping to do some investigating to see if there is something the bios is doing like a safety switch if the temps have been over a certain threshold for a given amount of time.

I discovered that if the temp is over 80C for 10sec, the laptop will shutdown. Found this out trying to encode some ALAC files :( So maybe HP has something if the temps are over 70C for a given amount of time?

The EC does get involved if temps start to go that high... Best to be certain you're not doing that by having appropriate reaction/setup in FTAB,etc.

I've been testing your silent temps FTAB from your github (via maciasl DSDT compile method) and I believe in that template the max fan speed kicks in at 75C.

I guess the 4330s was never meant to have a quad core in it :oops: so it does get pretty hot when I work on audio.

I will see if I can take out usb devices one at a time and see if that changes anything.

Its strange since it has really just started in the last 2 months or so.

But would you happen to have a debug version that shows what is sent to the EC? maybe something that outputs to console? If not, no problems, thought I'd ask.

And thanks for all your work and help!

Not sure what you mean by "sent to the EC." The EC reads its own information.
