Swapping GTX cards between machines... problems

[Charlie98]

Reference DESK and DESK3 in sig below.

I swapped my EVGA GTX760 and GTX560 cards between PCs... and now I have 2 separate problems:

1) The 760 in the Pentium machine... the fans now run at 100% at boot. PrecisionX has no control over the fans at all, and shows 0 RPM. The only difference between machines is I'm using a Molex>6-pin adapter to one of the power plugs.

2) The 560 in the i5 machine... now idles at 55C, where it would normally idle at about 30C, PrecisionX open or closed.

I have uninstalled and reinstalled drivers (even though both cards take the same drivers...?) and it didn't help. The 560 used to be in the i5 machine, I moved it when I got the 760, and now back again; it never behaved like this.

Anyone?

Now the GTX560 is up to 59C idle...

Try different GPU software like MSI Afterburner, default fan on auto, can adjust user fan settings (button to right).

On one, may lower 100% fan speed, on other issue, may help increase fan speed to lower unusually high idle temps. See if that helps.

Did you swap them between machines that had Afterburner set up with a boot-time OCing or fan profile setting? Those may not translate properly to different cards. I would uninstall AfterBurner, uninstall the NV drivers, then re-install the newest NV drivers, and select "Clean Install" in the installer. Barring that, I would reformat your OS on both machines. Obviously, that's a less ideal solution.

Well, I had the assumption that the cards take the same NVidia driver... that's what I get, I guess...

I'm not using Afterburner, but EVGA's PrecisionX. I have uninstalled all drivers and reinstalled clean... and still. I don't normally run PrecisionX... only when gaming... which means the fan doesn't normally ramp up at all, even under benchmarks.

I also, in the case of the Pentium/760, defaulted the entire BIOS in an attempt to throttle it down.

In the case of the i5/560 I wonder if it's not an issue with voltage... it's acting just like an overvolted CPU... but the ASUS board didn't do this will the 760, with no other changes.

Just after the new year I'll be rebuilding all 3 machines (swapping parts around and upgrading the Pentium PC to an i5) so I will be clean installing all 3 OS's. Hopefully that will address the issue... I had to pull the 760 out until then.

Could it be that thermal temps in each case are different due to different cards?, hence different fan speed to compensate.

Not at all. The builds and cases are very similar, the 560 was the previous resident of the case it is in now, where it's idling at 55C... the only difference is the mobo.

In the other instance, the fan immediately ramps up to 100% at boot... not because it is seeing a load.
