Part 1, The Programs
1. Download NSSM and Extract '\win64\nssm.exe' from the ZIP file to 'C:\Windows\System32\nssm.exe'
2. Download and Install SpeedFan
 
Part 2, SpeedFan Setup
1. Open SpeedFan, Check the 'Do not show again' box and click 'Close' - Do this Twice
2. Check the 'Automatic fan speed' box and click 'Configure'
      Basic Configuration:
        • Temperatures tab - Uncheck everything Except 'GPU', click 'GPU' then set - Desired: '65', Warning: '85' and Uncheck 'Show in tray'
        • Fans tab - Uncheck everything Except your Radiator fan - You'll need to figure out which fan this is on your own
        • Voltages tab - Uncheck everything
        • Speeds tab - Uncheck everything Except your Radiator fan
        • Fan Control tab - Check: 'Advanced fan control'
        • Options tab - Check: 'Start minimized', 'Static icon' and 'Set fans to 100% on program exit' | Uncheck: 'Debug mode' and 'SMBus'
        • Advanced tab - Select your Super I/O chip from the drop down, Select the output that controls your Radiator Fan then set it to 'Manual' and check 'Remember it' - You'll need to figure out what output controls the Radiator fan on your own.  On my board the outputs are called 'PWM 1-5'.
       ---
      Temperature vs. Fan Speed Curve:
        1. In the Fan Control tab click 'Add', Type 'GPU Radiator Fan', click 'OK' and then click 'GPU Radiator Fan'
        2. Check 'Controlled Speed', choose your Radiator Fan from the drop down and set Method to 'MAX of speeds'
        3. Click the 'Add' button on the bottom, Select 'GPU - GPU from GeForce Video Card @ $XXXX on PCI' and click 'OK'
        4. Click your GPU in the Temperatures box, set Hysteresis to '4' and use the arrows to set Min/Max Temperature axis of the graph to '36°C/72°C'
        5. Change the graph to your liking or match the graph I attached below for 0 RPM mode - Note: PWM fans are able to start spinning at much lower percentages compared to Voltage controlled fans (3-pin vs 4-pin)
       ---
      Testing:
        1. Minimize SpeedFan, Stress test your GPU and monitor temperatures until they stabilize - If the temperatures are too high adjust the Temp/Speed Curve
        2. Go back to the 'Fans' tab, uncheck your Radiator fan and click 'OK' - No need to use resources monitoring the RPM as SpeedFan will be running with no GUI
        3. Exit SpeedFan and make sure the Radiator fan goes to 100%
 
Part 3, NSSM Setup
1. Press 'Win+R', type 'nssm install SpeedFanSvc', click 'OK' - DO NOT call the service 'SpeedFan', you will break SpeedFan
2. Application tab - Click the '...' next to 'Path', paste '%ProgramFiles(x86)%\SpeedFan\speedfan.exe' in the box and press 'OK'
3. Application tab (1) - Paste '/NOSMBSCAN /NONVIDIAI2C /NOSMARTSCAN /NOADVSMARTSCAN /NOSUMMARYLOGSCAN /NOSCSISCAN /NOCSMISMARTSCAN /NOARECASCAN /NO3WARESCAN' in the 'Arguments' box
4. Details tab - Display Name: 'SpeedFanSvc', Description: 'Monitors and sets custom RPM curves for system fans.'
5. Process tab - Priority: 'High' and Uncheck 'Console window' - 'High' makes sure SpeedFan still gets priority when CPU usage is near or at 100%
6. Exit actions tab - Delay restart by '3000' ms
7. Click 'Install service' and Restart Windows - If you don't want to reboot you can also manually start 'SpeedFanSvc'
 

This is awesome!  Thank you!

Glad to help :D

BTW guys you can add other system fans to this and have SpeedFan control everything.

Remember to stop the service temporarily if you need to open the SpeedFan GUI or if you need to Update SpeedFan, and if you're removing SpeedFan make sure to remove 'SpeedFanSvc'.

• How to remove SpeedFanSvc: Press Win+R, type: 'nssm remove SpeedFanSvc'
• How to stop/start a service: Use Services.msc or type the following in a Admin Command Prompt; 'sc stop SpeedFanSvc' / 'sc start SpeedFanSvc'
• How to edit a NSSM service: Press Win+R, type: 'nssm edit SpeedFanSvc' - This is useful if you want to add/remove some of the disable switches.

Edit: And thank-you for the Ribbon @Cool GTX!! I didn't want to bump my thread but I marked your post as helpful. :)

In the 1070/1080 FTW hybrid kit, stock rad fan is not controllable. I can not even see RPM with corsair commander mini. Does this guide overcome this issue? Or is it just rubbish temp controlled fan?

If they are the same as the fans shipped with the GTX 1080 ti SC2 Hybrid, then they are only voltage controlled (non-PWM) and have no RPM sensor (only 2 pins used of the 3 pin connector ... but I need to double check that, since I'm not 100% sure now [Edit: confirmed!]).

Thank for you for such a great guide! I will be sure to make use of this when my Hybrid card arrives soon :)
 
One question though: I guess there is no way to have ASUS AI Suite software running at the same time as SpeedFan then? I know I can disable PWM control for each individual fan connector on the motherboard within the BIOS, but I guess this would prevent SpeedFan to work with it properly as well?

Nice post! I might give this a shot at home when I have some free time and post my results.

Now I just need some free time...

Since you seem to know what you are talking about I have a question
Once our warranty has run out.., and the pump dies.., is it possible to retro fit a new fan/cooler to the Hybrid card??
I know we're talking about 3 years warranty.., but 3 years goes quick and I don't think I will financially be able to buy a new GPU every 3 or 4 years..., you have to sell your first born here in Australia to get a high end anything (GPU,CPU,RAM, etc, etc)
(My current PC is about 8 years old (FX 8350.., HD 7870 in Crossfire) and has been/still is, a very good PC. The first game that has given me any trouble was Ghost Recon Wildlands).
Time to upgrade, but I need to be smart about it. Kids are wanting VR.., hence the top card.

I used NSSM to increase the power limit of my video card at every boot instead of using Precision or Afterburner.  I avoid overclocking software unless absolutely necessary; especially the buggy mess Precision has become.  You were my inspiration.
 
In NSSM:
 
Path: C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe
Startup Directory: C:\Program Files\NVIDIA Corporation\NVSMI
Arguments: -pl 217
Dependencies: NVDisplay.ContainerLocalSystem
 
Sets my GTX 1080 from 180w power limit to 217w power limit at every boot.

 
EDIT:  And by use of nvoc.exe which is a console command executable available on GitHub, I can do likewise with nvoc to overclock the video card at boot.

I am loving it.  A couple commands, one time, and then it just runs the way I want it to run without needing to have a buggy program running all the time in the background.  And since it is watercooled, I don't need to have Precision running to control a fan curve.

Thanks for this post. I could use some advice though... Speedfan doesnt jive with my chipset, MSI Z170 and refuses to regulate fan speeds or even properly display RPM's or temps. From looking through the speedfan bug tracker it seems to be a common thing with this series of MSI boards, it just doesnt work. Any other alternatives? I Would like to be able to have some degree of control over the fans on my $850 card.

You could use the functionality built into your motherboard's BIOS to set the fan speed to a compatible motherboard header based on CPU temperature. In most rendering situations -- especially gaming --, GPU load creates CPU load. So, CPU temperature works pretty well for controlling GPU fan speed. Just make sure you don't use a zero RPM setting in such a situation ... just in case.

thanks ill haft to try these solutions out

Mount radiator above card

Very nice

Personally I don’t really find that there’s that much a difference in volume. It’s just a different sound. If you’re thinking about getting one solely for silence you might be disappointed. I’ve had several hybrid cards and you will definitely hear a low hum from the pump unless you open up the card and connect the header to your motherboard to lower the speed. It won’t necessarily be much quieter but a hybrid card will definitely cool a lot better at about the same volume and keep frequencies more stable. So if performance is priority number one go for it.

what is actual noise difference between fan or hybrin on gpu?

I think hybrid has an advantage, but to realize the advantage, the radiator fan would have to be replaced with a better one (better brand, and PWM). Stock setup is probably louder than non-hybrid at low load, but probably similar at high load.
