Read GPU Temperature

[Wanja]

Can I read out the temperature of my GFX Card (Nvidia) by using AutoIt?

Is it possible to read out the nvidia driver temp display without opening the window?

I want to write script supporting me with GPU temp messages while I playing games

any suggestions?

Excuse my bad english ^^

I have written such a proggie. The limitations are that the Nvidia Control Panel must be open when you run the program although it hides when it starts it logging.... Nvidia wouldnt share their resources to call the dll right away through DllCall() although i contacted them 5 times...

Unfortunately i dont have the source code (formatted by accident) but i have an exe version...It logs the Temperature every 30 secs in a log file on desktop....

EDIT:

And BTW "This is not a general support forum!"

Hello hgeras

Found this on the Nvidia SDK site and thought you may be interested. It is the API documentation for the Nvidia Control Panel API.

http://download.developer.nvidia.com/devel...olPanel_API.pdf

SDK example page is (NVIDIA Control Panel API)

http://download.developer.nvidia.com/devel...es/samples.html

@44Harry:

Thanx for the info...It seems that it is exactly what i wanted although i hadnt find it 6 months ago when i had made the other proggie.Now i'm gonna find out how to make this work and re-write the whole code....Expect it to come in a few days....

Yeah thx for the api link ^^

so far I found this:

NvCplGetThermalSettings()

Function

Prototype

BOOL CDECL NvCplGetThermalSettings(IN UINT nWindowsMonitorNumber,

OUT DWORD* pdwCoreTemp,

OUT DWORD* pdwAmbientTemp,

OUT DWORD* pdwUpperLimit);

Parameters In UINT nWindowsMonitorNumber -- The display number shown on

the Windows Display Properties->Settings page.

A value of 0 indicates the current primary Windows display device.

DWORD* must be a valid pointer --

pdwCoreTemp -- GPU temperature in degrees Celsius.

pdwAmbientTemp -- Ambient temperature in degrees Celsius.

pdwUpperLimit -- Upper limit of the GPU temperature specification.

Return Values True on success.

False on failure.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

So I wrote some script stuff:

Dim $pdwCoreTemp

Dim $pdwAmbientTemp

Dim $pdwUpperLimit

$nWindowsMonitorNumber = 0

$dll = DllOpen("nvcpl.dll")

$result = DllCall($dll, "NvCplGetThermalSettings", $nWindowsMonitorNumber, $pdwCoreTemp, $pdwAmbientTemp, $pdwUpperLimit)

MsgBox(4096, "Test", $result , 10)

DllClose($dll)

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

But I got the error message that the nummber of parameters in the function call is not correct...it only works with one parameter:

$result = DllCall($dll, "NvCplGetThermalSettings", $nWindowsMonitorNumber)

The result is zero ...

well any suggestions how I can get my variables filled ? ^^

[Wanja]

I worked out this:

Dim $pdwCoreTemp

Dim $pdwAmbientTemp

Dim $pdwUpperLimit

$nWindowsMonitorNumber = 0

$dll = DllOpen("nvcpl.dll")

$result = DllCall($dll, "NvCplGetThermalSettings", $nWindowsMonitorNumber, "long_ptr", $pdwCoreTemp, "long_ptr", $pdwAmbientTemp, "long_ptr", $pdwUpperLimit)

MsgBox(4096, "Test", $pdwCoreTemp)

DllClose($dll)

$pdwCoreTemp is still empty but no more errors so far ^^

seems the dll call fails...

help ^^

[w0uter]

$result is an array that contains the data.

[hgeras]

Your syntax is not right... You have wrong number of parameters...Try this,I get no errors but right now I've given my 6800 Ultra and i have a MX440 which has no temperature control....Try this out and tell me...

Dim $pdwCoreTemp
Dim $pdwAmbientTemp
Dim $pdwUpperLimit
$nWindowsMonitorNumber = 0

$dll = DllOpen("nvcpl.dll")

$result = DllCall($dll,"int", "NvCplGetThermalSettings", "int",$nWindowsMonitorNumber, "long_ptr", $pdwCoreTemp, "long_ptr", $pdwAmbientTemp, "long_ptr", $pdwUpperLimit)
If @error then msgbox(0,"","ERROR")
MsgBox(4096, "Test", $result[2])

DllClose($dll)

C ya

[Wanja]

YEAH IT WORKS ^^

Thank you very much

[hgeras]

It works?!? I chose a bad time to not have my 6800.... Are u sure that works? Do me a favor and tell me this code works too....

$a = DllStructCreate("dword;dword;dword")
if @error Then
    MsgBox(0,"","Error in DllStructCreate " & @error);
    exit
endif

$dll = DllOpen("nvcpl.dll")

$result = DllCall($dll,"int","NvCplGetThermalSettings","int",0,"ptr",dllStructGetPtr($a,1),"ptr",dllStructGetPtr($a,2),"ptr",dllStructGetPtr($a,3)) 
If @error then msgbox(0,"","ERROR")
MsgBox(4096, "Test", $result[0] & " " & DllStructGetData($a,1))
DllStructDelete($a)
DllClose($dll)

It tells me:

DllStructCreate(...)

is an unknown function

[layer]

It tells me:

DllStructCreate(...)

is an unknown function

You need the latest AutoIt BETA if you want those functions.

[hgeras]

You have to have the latest beta installed as layer indicated.But even if you have it, SCiTe will again say that cos it isnt updated with the new definitions... Run it in "Beta Run" Instead of "Go"....

C ya

[Wanja]

I tried again with Beta:

it does work

[Wanja]

I've got another question if you don't mind:

I'm not so familiar with AutoIt Gui, well does there exist a way to print (let's say the GPU temperature ^^) on screen even if I run a game in fullscreen?

I tried to create a gui but when I started a game it always pops to background...

I know some tools able to print the fps on screen does AutoIt got such a feature?

excuse my bad english

[hgeras]

Go here and check why this is not possible...At least by me... and tell me if you like the program....

C ya

[Wanja]

this would be a nice feature request ^^

btw: my Logitech Keyboard got some special funktions and if I activate them I get a message on the screen even in games. Perhaps the AutoIt authers can implement something like this? ^^

hi  hgeras

i try to use this code to read NV VGA temp , but it failed...

can you help to solve this code problem ?  thanks!

[Jos]

Mmm 17 years later you expect an answer without telling us the problem other than "it doesn't" work..  good luck with that.

 

 

[debbiejames]

Sorry !  I should tell you more ..

I had try this code , I found that DllCall()  will return error , the @error return code is 1 , that means "unable to use the DLL file" 

so I dont know what next step to do ..

and I also  google  about  the "nvcpl.dll" file , but nothing help ..

so i reply this post .. may someone can help ?  thanks 

 

$result = DllCall($dll,"int","NvCplGetThermalSettings","int",0,"ptr",dllStructGetPtr($a,1),"ptr",dllStructGetPtr($a,2),"ptr",dllStructGetPtr($a,3)) 
If @error then msgbox(0,"","ERROR")
