eGPU fan not working

Deffington · Apr 18, 2017

Hello,
I need some help with eGPU setting up.

I have Corsair SF450 PSU, EVGA GTX 1060 for eGPU and GDC dock (mPCIe). Everything is wired, the LED on GDC is green, but fan is not working. It only spins for a brief moment on reboot, then stops.

I tinkered with drivers ignoring this, but even though I got the second display working for few seconds, the fan was still steady. I think I actually need to solve this first, before drivers and famous error 43. Do you have any idea how to get it working? Thank you!

It got quite hot during the experiment with drivers, I'm quite sure that the fan would be working at that temperature and temperature rise (otherwise it would have no treshold in real application). We are talking about the fan not spinning before there is any driver installed, so I doubt it could be affected by any kind of custom profiles. Am I wrong?

Okay, maybe it's the one with 0db mode. I was basically told to ignore it until it get's like 90°C. Thank you!

Unfortunately, I'm running into another errors, first I get error 43, which according to TechInferno could be fixed with older drivers, 372.70, but this driver crashes on install with this: Could not create folder "C:\Windows\Temp\NVIDIA\ControlPanelInstallerTemp". I'm basically getting this error with every desktop driver version I'm trying to install for the 1060. Any idea?

Oh, DDU tool! I must have left something when I was doing it manually. Thank you, I was able to install the driver now. EVGA Precision XOC solves the fan, it looks like I do have the 0 db model, but after setting an aggressive curve it works fine.

Unfortunately for me, the eGPU works only for a few minutes after driver installation and then crashes back into error code 43. Funny thing is that when it works, it shows both dGPU and eGPU working correctly under same driver, like dGPU could run under desktop driver version.

Full hardware: Clevo W150ER (XMG A502), i7-3610QM, 8GB RAM, GT 650M dGPU, GTX 1060 3GB eGPU via GDC Beast mPCIe wifi slot with SF450 PSU. OS Win10 64-bit.

I found the issue. The 372.70 works, but when I connect laptop to internet, it automatically downloads and installs 376.54 which ends up with crash. It happens just in few minutes.

A problem is, that I don't have any 'Update' tab in my NVidia control panel like it's shown here http

/www.nvidia.com/object/nvidia-update.html. I also tried this: https

/forums.geforce.com/default/topic/529337/how-to-disable-automatically-downloaded-latest-nvidia-drivers-/, even though it looks a bit different on win10 and doesn't work. It sucks the update every damn time. They say it's windows update problem anyway.

I would prefer to disable just the Nvidia update, not all automatic drivers that make the PC able to plug'n'play. I found this https

/support.microsoft.com/en-us/help/3073930/how-to-temporarily-prevent-a-driver-update-from-reinstalling-in-windows-10. I have Win10 Home version 1607. But I got 'unexpected' error trying to run the package. I really didn't expect the error there... Can someone shoot my troubleshooting wizard?

I've got the setup working on Windows 7. I was testing it for the last few days and it looks okay. It's actually a good idea to have two OS; for dGPU and eGPU.

Thank you for all the help!

I summon you once again! Grant me a wish, a working system.

I tested the setup on win7 and win10 (managed to keep the 372.70 driver). It runs, but the driver keeps crashing and recovering. It happens like once an hour under load. I could live with that if everything was working after recover, but some applications are not coming back to screen and need to be restarted. That is super annoying.

I found and tried this: https

/tinkertry.com/display-driver-nvlddmkm-stopped-responding, but without success. I also read a mention about the problem being the difference between VRAM and RAM, but that sounds like sh... not right. Maybe you have come across similar problem before?
