17 R1, Windows 10, GPU fan not working

That should fix the broken graphics driver.

Sorry for very late aswer.

I buy new pc so im ready to try some things on alienware.

I try disable and instal NVIDIA - 451.67 - Modded But say it is not compatible What will be my next step?

After few trys... it work the driver but not the fan! same problem as before

It's hard to know exactly what the problem may be. I don't want to tell you to flash a new vBIOS as it can brick your card if it's not done correctly. If you want to try it, it's up to you.

Did you ever find out what vBIOS the card currently has, using GPU-Z?

This one?

im 200% sure it is a software problem cause i now using speedfan control software for turn on the FAN.
I need that software, other way the GPU fan is at 0% speed and alienware shut down cause temperature.

I'm going to flash bios tomorrow and if that works I'm gonna marry you hahaha thanks a lot is hard to find stuff in English when I am Spanish dude. But English is always the solution

OK so that vBIOS is for the AW 18 Slave GPU. This is a special vBIOS just for the secondary card in the 18. Your card was most likely pulled from the Slave slot in an 18. This vBIOS was not designed to be run on the primary GPU so I am reasonably sure that this is your problem (hard to be 100% sure until you try a new one). I have read a few guys having fan control issues when moving the slave GPU into the master slot. 

I believe the correct vBIOS for you will be 84.04.35.00.05

Have a read through this

Well my wife may have something to say about that, funny thing is that she is Spanish.

Just remember that you're flashing at your own risk. Things can go wrong, rarely but they do. 

I'm no expert on flashing vBIOS' but I've done it a few times. You need to remember to disable the GPU in Device Manager before you do the flash. Good luck and I'll try to help where I can. I always flash using CMD in Windows but there are a lot of people say you should use a bootable USB drive. Up to you. If you do it through Windows, i think you do it like this;

1. Create a folder in your C: drive called NVFlash

2. Download NVFlash and extract the files to your new NVFlash folder

3. Find and Download the BIOS ROM from TechPowerUp. Place this file in your NVFlash folder. Write down the ROM name for later

4: Use GPU-Z to save your current vBIOS on the PC

5: Disable the GPU in Device Manager (I'd also turn off wi-fi to make sure there are no Windows Updates)

6: Run CMD in Administrator mode

7: Type cd C:\nvflash

8: Type nvflash64 -6 ROM_NAME.rom

9: It should run the flash. Type exit once it is complete.

10: If everything worked then you should just go back into Device Manager and enable the GPU and restart the machine. 

If it fails during the flash do not restart your laptop. Keep trying to do the flash and hopefully it will work. 

Ok good job!

Btw i can test my old 880M before doing flash you think is good idea?

Yes, definitely a good idea just to check. I hope it works out for you. 

880M Fan Working

980M fan Not working

I guess my 1º time ever NVflash is going to happen today

May the flash be with you 

aslo notice this look no bios on card but i check it just after i done it and was 84.04.35.00.05 donñt know why disapear
