I am trying to control the fan speed of the video card but it seems it is stuck at any % is set on drivers but indeed is running at 100% fan speed, I have tried uninstalling with DDU and manually wiht the drivers but none make any change, even at boot the fan speed is 100%

I am using win10 proffesional 64 bit, I have tried 15.12,15.11 and 15.11.1(beta) drivers
 
is anything like msi afterburner installed? has to be. Is the card temp ok? maybe the heat sink came loose and its trying to cool off?
 
Was the card always spinning at full speed? Or is this something new since you started trying to adjust it?

From Boot to windows 10 startup has full speed on the fans.I tried booting with the 2 Bios

I tried a different card and it has low speed when it boots
 
Is this a new card for you? Has the card ever not had this issue? Are the card temps fine or is it burning up like a dumpster fire when at 100% load? Did you remove the cooler on the card for any reason? You aren't providing a lot of details here...
 
I bought this card used but temperature wise is fine only the fans cant be controlled with Catalyst or MSI AB
 
1 Card fans can be controlled by cards bios which means old owner could have modified the bios for faster fan speed or
2. Someone rewired the card fans to a constant 12 volt wire somehow

i think i would look into updating the cards bios to make sure its not using a modified bios, then you have to reinstall the drivers and see it it worked.

TPU DB bios or sapphire´s webpage bios? also each 7950 uses a different memory IC, then I dont know what BIOS they uploaded
 
Signed up to reply (lurked here for years and years!)

I have a Sapphire 280x and this behavior started happening to me recently. I uninstalled drivers, reinstalled drivers, changed fan settings in afterburner all no avail.

What fixed it for me was actually giving the CPU heatsink a good old clear out, and that seemed to fix it.

My symptoms were:
1. Fine one day, then randomly for no reason the fans all span up to 100%
2. Once the fans were in 100% mode, as soon as the PC was turned on, the fans were spinning up to 100% immediately.
3. Leaving the PC off overnight didn't resolve the issue (to test once the machine was cool)

Not sure if the system is detecting some overheating somewhere (have an Asus Maximus VI Hero).

Give it a try, may fix your problems!

Maybe ask the previous owner if they changed the BIOS.

it is the stock bios


some days ago I tried installing a program (trixx) but before opening it the fan lowered the fan speed and i changed the fan speed to around 45% and then to 50% but when i set it back to 30% the fan got stuck again at 100%, i doubt it is the bios

Not sure if you tried my idea above, but another thing you can try is popping out the CMOS battery on your board. A full reset of the bios might help.

On graphics card fan speed? Be first i ever heard that working.

OP with the additional info you provided it seems most likely you have some software your unaware of is controlling your cards fan speed. Can you post a screenshot of your installed programs? A screenshot of running tasks could be helpful also

Reinstalled windows(the fan was at low speed with 15.11.1,I had followed some steps in amd forum) then when i installed crimson 15.4 and reboot the fan was again at 100% on boot and windows

Strange one, I know, but It worked for me!

Incidentally my GPU was hardly dusty at all compared to my cpu fan. As soon as I cleaned it up it worked a charm!

mobo bios does not control gpu fans. cpu yes but I have never seen gpu control in bios. the video bios controls fan speed and you CANNOT just enter it to change settings. why are you using old 15 series drivers? goto amd and get the new 16.4.1. ddu the old and install just the newest.

edit: corrected speeling
 
I have tried to run the card with any% but the card tried to push 100% and the % is set on overdrive and then keeps at 100% until i set at 100% for a while and then reduce the speed,and continues doing the same
 
Ok so you've wiped and reloaded windows installed two sets of old drivers and the issue came back. Try this:
Download and run the newest DDU. When it asks for launch options select safe mode say yes, let it reboot to safe mode, run DDU and remove everything. Reboot when prompted. Then do it a second time to remove any left overs. Once its booted to normal again it should be running on basic windows drivers. Uninstall anything like trixx or afterburner, speedfan or open hwmon. Reboot again.
Now check the fan speed. Is it normal now? If not, you need to update the bios. Go to TPU.
If it is, go to AMD.com and get the NEW 16.4.1 drivers. DO NOT install old 15 series drivers. DO NOT install trixx or afterburner or anything else.
See what happens.

save you bios with gpu-z then upload it to mega or whatever and let one of us take a peak at it. As it sounds like someone modified the bios - Its the only explanation. Also follow what Pend said to do cause thats needs to be done as well.

I have compared the fan curve with VBE7 and they are about the same, and about the pendragon steps I have done something similar

something similar is not the same... that page is more than 3 months old and still talking about 15 series drivers. It worked after you reloaded windows. then you put 15 series drivers on and trixx and whatever else youre using and the problem came back. it is obviously something you are installing and it seems to me like your fighting our suggestions(did something simular, no bios posted but "i looked its ok"). good luck...

When you say ABOUT the same, as in IS the same or there were some notable differences. If so what was different? It Should be exactly the same under normal circumstances. For what it worth i think that card has alternative bios's.....like one is called boost bios or something

I suspect whatever the OP is using to "monitor" the problem is causing the problem. Pretty confident if the OP wiped Windows and then reinstalled just the new Crimson driver then thing would be fine. Seen this so many times, people create their own issues trying to fix things. This is especially true when people install multiple monitoring or tweaking apps, the shit often just doesn't play well together.

It should be the fan PWM control related because I have done a clean install of windows 10 and the problem exists even with 15.11.1beta drivers
