MSI GTX680 Twin Frozr fan issue

Hi Guys and Girls.

Apologies if this is a repost, I've searched google and TH but can't find any example of this issue.

I've bought a second-hand card but it appears that the fans won't run at all. They spin for a second or two on power-up but that's about it, and it will just sit there getting progressively warmer until I turn the power off.

The display runs, and I can see the POST screen, so it is working.

I'm using a 1000W PSU with dedicated PCIE rails so I doubt its a power issue. I've tried it on two boxes, one is a an AMD Phenom X6 and the other is my graphics workstation running a pair of Opteron 6328s, the result is the same.

I'm a bit worried about trying to install drivers and run it for more than a minute or two with no cooling.

The info I have found all seem to tell me that at least one fan should run all the time, albeit slowly if the GPU is idling.

Any ideas?

Cheers, Tim

Well, that seems unfortunate. I believe running 2D without the fans won't be a problem. There is a massive heatsink over the GPU, the thermal solution is designed for almost 200W and idle TDP is about 15W. I believe you could run 24/7 in 2D mode.

Anyway, if it was mine I'd go ahead and boot it, then try to create a fan profile in rivatuner.

Hi

OK well I installed it with the drivers I got from nVidia and the v3.01 of the Afterburner utility.

After trying to create a fan profile, it runs for a little while, then the speed of the fan gradually drops to zero and stays there. The Fan Speed looks like its asking for 40%, which slowly rises as the GPU temperature increases. I can get the fans to spin if I set the level to 100%, however it's bloody noisy and is not something that I want to do.

Definitely seems like a hardware issue as this happens in both Win7 x64 and XP64 SP2.

Please check this thread, might be useful to you:

Also, it looks like you can test those fans by connecting them to the motherboard as if they were case fans.
