SOLVED: gpu fan not running at all (Nvidia 7600 Go, Vista 32)


BugsBunny

Recommended Posts

Solution (even though a rather strange one) here ..

----------------------------------------------------------

I just switched from XP, where the gpu fan would kick in when grafics intensive tasks are running as it should. Now in Vista, with graphics intensive tasks, the gpu + the entire left side of the laptop gets really hot, and Vista sometimes even crashes .. :) (according to HWMonitor 8x/9x °C, whereas with XP before and now with OS X it ranges from 5x to 6x °C).

A BIOS upgrade to 4.3 did not bring about any improvements (only Vista not waking up from sleep anymore), so I downgraded back to 4.2, and wake-up-from-sleep works again.

The fan is still OK, because if I restart and the gpu is hot from Vista it runs at 100% untile the kernel loads and turns the gpu fan off. The cpu fan works as it shoud (it now even works more because it is foced to deal with the additional heat from the gpu). Also I have Mac OS x86 installed, and the gpu fan is running there from time to time as it should, so the fan and the BIOS are fine.

I have tried all I could (different revisions of Nvidia drivers (modded/ unmodded) from Toshiba, Microsoft and Nvidia, ntune, chipset drivers, BIOS..), all to no avail.

The GPU fan control in ntune remains greyed out.

Is there a way (some setting) somewhere in the infs which can (force) enable fan control? I uploaded a little inf package right here, in case somebody thinks it is possible to tweak an inf so I get fan control.

Any input, idea etc. is greatly appreciated. I don't have any mind to switch back to XP just because Vista or the NVidia Vista drivers do not find my gpu fan anymore .. :)

Thanks a lot,

Bugs

I am working in customer support, and more and more customers are running Vista, so I need to be very familiar with this OS. The Toshiba Laptop is my main machine, and apart from this gpu fan bug I am very pleases with both, Vista and my Toshi.

In RivaTuner the fan tab (as shown in the tutorial) is missing, too.. :) (link tp pic) which might be explained by what yantronic wrote here and boogieman quoted here even more detailed about manual gpu fan control not working with some grafics adapters respectively their fans, but that still does not explain why the gpu fan is totally dead in Vista here.

Does anybody have any clues?

Don't listen to those people who tersely and disrespectfully tell you to ditch your OS. Some people just don't realize that sometimes users do not get a choice about which OS to run. Which driver version are you running?

hey Michael, yeah you're right, my experience is that the people that answer first in a topic are the least understanding and the least helpfull :) - but who really cares ..

Which driver version are you running?

so here's my driver history:

  • with the driver 156.66 as supplied by Toshiba for the NVIDIA GeForce Go 7600 in Vista, the screen on an external display flickers frequently - constant blackouts of maybe 1/3 of a second = very irritating
  • same with the driver 163.69 which Micosoft supplies for the NVIDIA GeForce Go 7600 via Windows Software Update
  • the latest WHQL from Nvidia 175.16 breaks wakeup-from-sleep in Vista
  • tried 169.25 (WHQL) - that one does NOT flicker AND delivers proper wakeup-from-sleep, so so far I have been sticking with this one for now (stopped trying thereafter, so I bet there are other versions without flickering AND proper waking-up from sleep)

As expected, disabling driver signing did not bring about any positive changes because from what is written across the web driver signing only effects fan control in Vista 64, not 32.

In the meantime I have done some more research, and found out quite a bit:

  • one guy with Vista 32 and a Nvidia Geforce hat properly working fans up to Nvidia driver 100.65. Thereafter most people had fans that were always on 100% (example). So accoring to some people, at some driver version (couldn't find out which one exactly) NVidia seems to have decided to, instead of fixing this because it worked before, switch the fan to "lowest speed", controlled by some ACPI function. But when I hold a wet finger or a flame in front of the vents it is definitely off totally now !!! [EDIT]: as always, this only seems to affect some grafics adapters repectively machines
  • about RivaTuner: "Currently RivaTuner doesn't provide driver-level 2D/3D fan speed control features under Vista due to NVIDIA Vista driver's limitations." This applies to certain grafics adapters, and it seems to apply to my Geforece 7600 Go.
  • about ntune (link to quote):
    Fan control has been moved from the graphics driver to nTune. Right now nTune has a problem with fan control [..] as well as saving and loading profiles. We will have to wait until nTune is updated by development for user fan control. I'm sorry but we can offer no workaround in Vista.
    Best regards,
    NVIDIA

However, somebody posted that he had fan control in Vista 32 working with nTune 5.05.25, then updated to 5.05.47 and lost it right away.

So I will now uninstall the current 169.25 grafics drivers, reboot, install the 100.65 for Vista 32 (with modded inf I guess), reboot again, install nTune 5.05.25, and see what nTune 5.05.25 and RivaTuner 2.09 say abot this gpu fan .. :) well actually I hope it blows again then, because before upgrading to Vista (fresh install), I never had a fricken need for any "fan control" in the first place ...

Good luck. I hope that you solve the problem. I had the same thing happened to me when I had my old Alienware with the geforce go7600. In XP, the fan worked as it should and everything was running cool. But, strangely in Vista (I did a dual boot configuration...) the fan didn't blow as it should, causing overheating. No driver worked properly. So, I just went back to stock drivers since they would downclock the GPU when power wasn't needed and it kept my laptop cooler. If you come up with a solution, let us know.

@ F3nNec: even though I agree with you to a certain extent (and have been around computers and OSes way before you, since the days of DOS and Mac OS classic): since you live in Moscow accdg. to your sig, go swollow a bottle of Vodca and crawl to bed .. :)

@ Kobe: yeah I figured I was not alone with this, thanks for sharing your experiences. So now I have 100.65 int. WHQL installed with the org inf (the modded one must contain errors because 100.65 would not install with it), but still neither fan control (ntune/ RivaTuner) nor a blowing fan (not even slightly).

From what I know this is NOT Microsoft's fault, but: 1) Nvidias and 2) Toshibas (amongst other Laptop manufacteurers). Here's why:

what Nvidia did when they found out quite a while that they were uncapable of coping with driver writing for Vista, esp. for OEM cards like the ones built into Laptops, and because communication and collaboration between NVidia, OEMs and Microsoft simply HAS HARDLY BEEN WORKING for a very long time now, they turned the fan speed down to "lowest". The speeds of the different levels are programmed in the DSDT table (part of the ACPI) in the BIOS. Many (!!) Linux people have had these (and other) problems with fan speeds, so what they did is extracted the DSDT with a decompiler, coccected the erroneus entries in the DSDT (in my Toshiba: at least 18, but probably more), and reinjected the corrected DSDT into the kernel during Linux boot, overwriting the faulty values in the DSDT, and - boom - had proper fan speeds (GPU, CPU), either with a fixed or even an altering speed, depending on what could be corrected.

In Mac OS x86 one guy has rewritten the IOPCIFamily.kext (darwin open source), which also corrects wrong DSDT values, turning many PCs and Laptops into full Macs incl. working fans.

Since neither the Micro$oft's Windows kernel nor their ACPI/ PCI specs are open source, there is only one other way: recompile the BIOS with a corrected DSDT table, and apply it! For that sake, I have contacted a very gifted programmer who has been recompiling dozens of BIOSes with corrected DSDT tables ..

I'll post into this thread as soon as I know more. If anyone comes up with a solution, please let us know. But please no XP/Vista flaming anymore, the web (and even this forum) is oversaturated with that kind of stuff - we don't need any more of that - pease ....

@ Kobe: what do you consider "Vista Stock Driver for Nvidia Geforce Go 7600"? You mean the 163.69 - 7.15.11.6369 (11.09.2007) that Windows Update downloads when reaching the desktop after install? Do you still have Vista installed now, and which driver do you have running?

I have not done (no time) representative heat tests, but which driver version would you say keeps the gpu the coolest?

Thanks,

Bugs

Don't say this too quickly. I often reply first to topics, and I try not to be rude like this. I am sorry, but I don't think I can help with your problem. I once was helping someone troubleshoot this problem on a similar Toshiba, but I never did get if fixed. Good luck.

So I just upgraded to Nvidia's latest official 175.19 WHQL which was published just some hours ago, with an inf I modded myself, but, as expected, no fan, no wake-up-from-sleep :) (but at least no flickering on my external) ..

I have not tried any of the 177.xx yet, but I do not think they would do any good for a 7600. So I will negotiate with the BIOS programmer again ..

For my previous alienware laptop m5550, I used stock drivers 101.34, I don't have this laptop anymore, but since then they have released newer drivers, the 165.32 beta drivers.

However, now it's a different story with my newer Alienware.

Did you try the 175.80 driver for vista 32 yet?? It's pretty stable and it downclocks the GPU automatically when the power isn't needed. That's what I'm using right now on my notebook and it stays pretty cool.

Hi there,

Im very interested in your topic because i have this exact problem on my Asus F3JV. It has been months that i am desperating about finding a solution with this fan problem an overheating problem in general.

I'm sure this graphic card is prety decent and i am very happy with my laptop but this problem is so annoying that everytime that i play a game and see my display screen flickers like you just told before.....it pisses me off!!!

I think a lot of people including me will really appreciate if you find a solution to this. I will constantly reading this topic until someone has a solution :) (and of course i am searching for it :) )

P.S. Bugsbunny if you know precisely how to recompile the bios with correct BSDT let me know how to do it :P

You need driver 167.59 WHQL from Toshiba: http://forums.laptopvideo2go.com/index....showtopic=17271

this is the best ever/latest they have released.

wake-up-from-sleep works, no flickering on my external, but the gpu fan still does not kick in. nTune's grafics test has the gpu overheat up to 97 °C, then nTune and the driver crash ..

downclocking cannot be considered a substitute for a running gpu fan .. and I have really gotten tired of checking out this- and that driver, but thanks for the info

Asus has the most errors in the DSDT tables of all manufacteruers, followed by Dell and Toshiba, including fan problems if running any other OS than Windows XP.

DSDT .. :)

It requires lots of knowledge! Recompiling the BIOS without messing it up isn't done just like that, it is a specialist's work. It can only be done satisfyingly with Linux tools right now, and even with all these tools there is some BIOSes which can either not be disasembled, or reassemled, or both. I cannot do it, and right now I just know this one guy who has figured it out for many BIOSes (not Dell, however), and even he says he only knows little about the vast commands in all the BIOSes there are.

Anyway, I already have one corrected DSDT table for the 4.2 BIOS my Toshi is running on right now, and another guy with Linux and Mac OS x86 is fine-tuning the DSDT right now under Linux. Also the programmer just told me that he can compile as soon as he gets the correced DSDT table, so I would say it is a matter of days.

Hi everybody,

I'm pretty interested in this topic too, because it's a whole month I have the same problem with my hp pavillion dv9000 and right now it is even a problem touching my keypad because it is extremely hot.

I use my laptop mostly for graphics, renderings and working with AutoCad and I was always satisfied with its performance. Vista 32 bit Home premium is mostly a problem because most of the softwares don't recognize directx 10 and I had to wait the vista releases, but besides that I don't have much to complain about.

But, back to the problem. The CPU fan starts running as soon as I start the computer and it work all the time 100%, even if the CPU temperature is around 40 celsius degrees, which shouldn't activate the fun like that.

Instead, a temperature monitor showed me the hard truth: the GPU fan isn't find and it doesn't work at all --> consequence: my GPU temperature is around 60 celsius degrees. I put book under the laptop, I cleaned the fans, but the situation didn't change at all.

Anyone of you has any further solution about this problem?

The TOSHIBA laptops I have used with Vista 32bit and NVIDIA like Go 7600 don't have any fan/overheating problems of any kind. Please note that the A100/105 series only have a single fan/cooling component for both the CPU and GPU at the same time. They run BIOS v6: http://ie.computers.toshiba-europe.com/cgi...iverLanguage=42

A GPU temp of 60 is not bad when on load; in fact it would be very normal.

So the gpu fan problem has been solved here in Vista, by a rather questionable means ..

What I did is reinstalled XP on a separate partition to make sure I was not suffering some sort of hardware defect. gpu fan as expected working fine in XP. Then booted into Vista, and baaannng - gpu fan even working in Vista. Turned the Laptop off, waited, booted Vista again, but this time without booting into XP before that, gpu fan still working.

Now, with the driver 169.25 for Vista 32bit which I recommend for the Toshiba Satellite P100-102 (and most likely others of the 1xx series) with the 7600 Go at this time (June 26, 2008), the temp is staying in the low 50s °C as in XP, and when running benchmarks not going above 65 (66 in XP).

Hard to believe, but XPs different ACPI moddel must have revived s.th. somewhere on my mobo (BIOS/ CMOS) that got stuck either in Vista or Mac OS x86, and could not be revived by reinstalling Vista onto that test partition.

The version of XP I installed is the one from MSDN with SP3 included. I also installed the latest Intel Chipset driver 9.x + Nvidia driver 162.18 WHQL international. No idea if these components were important, too, for triggering the gpu fan to finally kick in in Vista.

So anybody else with this kind of prob: try installing XP on a different volume, make sure the gpu fan works (just do a grafics benchmark test like the one in nTune and it should run), and check in Vista if it runing there then, too.

Thanks everybody for your input; I will post in here as soon as I have heard anything about my BIOS.

Sure, 60 degrees aren't bad, but I have them when I'm surfing internet, using word... nothing that makes the GPU work.

When I start rendering, the temperature rises until the laptop switches off without any warning. And this is a problem because I need this computer for working reasons and a render tooks about 4 hours to get ready. You can understand that losing any time 4 hours of work is creating me a lot of problem.

Moreover, my laptop is a HP pavillion dv9000 and it should have both fans, on cpu and gpu.

I don't know what to do actually, because even right now my keypads are so hot that touching them is a bit discomforting. Luckily, I have another desktop pc, but when I'm around for working reason, I can rely only on my laptop and you have already listen my sad experience with it.

Anyway, thank you for your reply... I'll keep on checking this topic, hoping someone will found a solution.

Sorry, your reply probably happeared while I was writing my reply.

Unfortunately, I can't install XP on my laptop. I've already tried, but it's not possible... I've written even to HP about this and they told me that since thic computer was built for vista, then it's normal that I cannot run xp on it. The installation process simply starts and then it doesn't detect my HDD... I've looked for the right SATA drivers, but Fujitsu doesn't distribute them, giving the same reason I got from HP.

Well, I'll find another solution. Thank you anyway :)

Assuming your laptop uses an Intel chipset, you could have downloaded the SATA drivers directly from Intel. Other manufacturers might provide their drivers too.

You can install XP on your Hp Pavilion dv9000 laptop. I have myself done it several times. Enter the BIOS and disable the SATA interface. The next time you boot with an XP CD, it will detect your Hard Disks.
