I bought this graphics card a week ago from pcandparts, it is a MSI GTX 970 GAMING 4G.
Great video card, runs games smoothly at high settings.

However, I've had some fan issues with it.
It has the Twin Frozr feature which allows the fans to spin only if the graphic card is in gaming mode. Other than that, the fans should be off at idle state.

In my case, I turn on my desktop computer, GTX 970 is silent. When I play games, one fan or the two (depending on the game being played) start(s) up.

However, when I quit the game, fans would keep running. I have tried waiting for one hour to see if they would turn off, but they didn't.
I have to manually reboot, so I shut down my PC. And I press the power button to power it on (Using the Windows 'Restart' option doesn't turn off the fans on reboot).

After manually rebooting, my PC would be silent once again.

Is my GTX defective? I doubt that it's meant to always run loud even after gaming .. :/
provide some data logging please

Which software can I use to data log my GPU?
This is my first pc build so I'm quite new to this stuff.
It takes about 2 to 10 minutes for the fans to stop after quitting a game, in your case perhaps the game is still running in the background or you have a case with bad air circulation, can you control+Alt+Delete after quitting the game to see if it's still listed as active?

Do you have an MSI Afterburner installed , by default the fans has a 0 rpm util the GPU temperature reaches 60 degrees Celsius , you need to check your fans profile through MSI Burner.

Also, you need to check the power management through Nvidia Control Panel, if its set to maximum performance , the GPU core clock will be locked to 1114Mhz, regardless of its load, this might raise power draw and temperature.

Also, check your GPU temperature while idle through GPU Z, if zero rpm fans it must stay on 30 degrees Celsius with regualr desktop usage (browsing internet etc..) , and enable some GPU statistics live while your gaming through MSI After Burner like (load , temperature , Fan Rpm % etc..)

Nope, the game's process ends as soon as I quit the game (any game basically).
I waited one hour for the GTX to cool down, and it does cool down, however the fan that is closest to the case's front panel stays on. The other one close to the I/O shield turns off.

Thanks for your reply,

I have MSI afterburner installed, ill check whenever I get home.
As for the nVidia control panel, i didn't change anything since I built the computer, so by default I don't think it should be locked to 1114Mhz. I'll keep you updated as soon as I'm home, and provide you with GPU statistics.
