Greetings,
Today I was replacing the thermal compound on my GPUs, all went well up until I ran Furmark and one of the GPUs went nuts... The fans started spinning like crazy, sounded like a jet and I immediatelly had to shut down Furmark. I am on the stock BIOS not the SSC one, so the fans are idle up until 60°C. But as soon as the cards reached 60°C one of the cards entered "jet-mode". Cant figure out why this started...
I checked the fan cables, all is OK. So I dont know why all of a sudden it started :(
Any help is welcome, thanks

Sounds like you need to flash the card back to the default vBIOS if you're not running the SSC one loaded from EVGA.

The card has double BIOS, all it takes is flip a switch directly on the card

You need to use the other vBIOS then as the one you're currently running has a more aggressive fan curve.

I said in the OP I am running it and NOT the aggresive SSC bios

Maybe you accidentally flipped the switch to the other vBIOS while changing the paste? The fan speed will increase after 60-65C. Maybe you're just really sensitive to noise?

Nope, I was running the SSC bios until now and switched back to stock today... I can record the sound it is a jet engine, fans spin at 100% right as it hits 60°C and I think it shouldnt be like that at all, not on the stock bios

Sounds like they have the vBIOSes loaded incorrectly on your card since it doesn't happen on the other one.

Doesnt seem like it... A month ago I had both cards at stock bios, all good, then I switched both to SSC bios, all good still... Today after feaplacing thermal paste for Liquid MetalPads one started to go nuts + yes I checked, the MetalPad stayed on the chip, didnt short anything

#1 Remove GPU fan shroud and make sure the GPU fan cable is fully seated and secure to the GPU PCB fan header. #2 Make sure the card is fully seated to the MB. Make sure the PCI-E power cables are fully seated and secure at the PSU side & GPU side. #3 Uninstall all monitoring software. (Precision, Afterburner, Speedfan, HWMonitor, etc.) #4 Perform a clean installation of video drivers. - Uninstall Precision X/Afterburner if installed, make sure to select "no" to saving profiles if asked. Reboot the PC now if you had to uninstall PX or Afterburner.
- Download & save graphics driver 350.12 to your desktop. Run the graphics installer located on your desktop once the download is complete.
- Select custom advanced install, under custom installation options uncheck all options except the physx system software, if you have a 3D capable monitor and would like to use 3D at some point please select both 3D options, check mark perform clean install, then click next to install the driver, reboot when asked.
If you're still having problems after performing steps 1-4 RMA the card as the fan controller on the GPU has a problem.

Hey, Sajin I did everything you suggested, removed shroud, applied regular thermal paste, uninstalled all monitoring software, did a reinstall of drivers + ran just the "faulty" GPU alone and guess what :) Works like a charm :) Now to test it with both GPUs in SLI and pray it stays OK :) Many thanks for helping, will get back to you with SLI results EDIT: Tried in SLI - everything works fine :) Thanks

My SC GTX 970 kicks the fan to 100% at 92c with the stock BIOS. SO yes its not normal for the card to do this. I personally don't care for EVGA's fan curve, so I just manually set the fan, depending on what i am doing, and the intensity of the program being run.

Well if your card is reaching 92 degrees centigrade then you have a problem with internal airflow. To verify this obtain a normal house fan (or borrow one). Open up the chassis side panel. Allow the fan to blow air onto the card. Check the temps at idle and under load.

The only reason the GPU got so hot was because i forgot to turn the fan up! silly mistake. Thats the problem with manually setting your fan speed. My 970 at 60% fan speed runs around 55c under 98-99% load!
