EVGA GTX 460 SLI Fan Issue (Fan stops spinning)

[popsicles]

I just built a new rig using a evga GTX 460 from my previous build, and a new super clocked evga gtx 460. When I play a game (crysis 2) under full load, the new card's fan will stop spinning (GPU stays on till it overheats). I have set the speeds on both cards to 720/1440 (so non-overclocked) using EVGA precision, and still have the same issue. I have tried switching the cards slots, and still the newer card's fan will stop spinning while playing.

I don't think it is a heat issue that is causing the fan to shut off, because I have tried cranking up the fan speeds on both cards to 100% and they don't reach over 53 degrees Celsius on full load. CPU temps top off at about 53 degrees as well, so no issue there.

So my question:

Is it a faulty card? Does it matter if one of the card's is "super-clocked" and one is regular, if they are both gtx 460's and I set them to the same speed?

Can't be a PSU issue can it? It stops spinning even when it is not the primary SLI card. I'm using the Thermaltake Toughpower 775w Bronze Certified PSU.



My Rig:
i5 2500k @ 3.3ghz (turned off turbo boost even)
Gigabyte z68mad2hb3 motherboard
2 EVGA GTX 460's (one superclocked, one regular, but running at the same speeds)
DDR3 Corsair memory 2000mhz (under-clocked to 1866)
2 Harddrives (750gb, 1tb)
775 Thermaltake Toughpower 775 PSU
El Diablo Full tower case


Any input / ideas would be greatly appreciated, thanks!

Sounds like the fan is bad, possibly a thermally sensitive component or trace on the circuit board. If it's still under warranty, and you registered it with EVGA, contact their tech support for a replacement.

I just bought the card about 6 days ago. Would I be better off sending it back to Newegg for a new card, or sending it to EVGA under warranty to get a replacement?

I would totally uninstall evga precision, the Nviida driver, then reinstall the Nvidia driver, imo, it could be one set of internal driver profile fans profile settings clashing with another. This is possbily something that could rear itself with precision but not msi afterburner which can also control your fan profile settings.

OK so if I use MSI afterburner there would be no chance of conflict from the gtx 460's internal fan speeds and the programs?

If Newegg will replace it and pay for shipping, that would probably be faster. The good news is, they live in one of your favorite areacodes:

Toll Free: (800) 390-1119

You can contact EVGA in another of your favorite areacodes:

Customer Support
U.S. and Canadian Customers: 888-880-EVGA (3842)

Since it's that new, someone should be able to help you pretty quickly, and the calls are on them.

NO, no guarantee, actually , depending on how coding, it could also cause a issue. IMO, you might be experiencing a worst case experience from these external programs intermixing with the driver/bios fan settings of these cards. With MSI Afterburner, I do select a custom fan profile , and then I also check sync settings, for all cards. I have identical cards, and experience NO problems of any kind. But I read of many people mixing also and having optimal experiences.

Your solution worked. I uninstalled evga precision, rivatuner, and speedfan, and then uninstalled/reinstalled the nvidia drivers. I played Crysis 2 without the fan stopping for 2 hours straight, no problems!!

I haven't downloaded MSI afterburner cause I figured it might cause another conflict, but it's working now so I don't need it anyway

Thanks so much.

I understand that this was not your problem but I just had a problem like this with a different cause. On a new build with an Evga 460 GTX everything was fine at first then a complete loss of video at random times. Got more frequent later and finally unusable. Blank screen that would be corrected with reboot, usually. Suspected MB, PS, Ram but turns out that it was the FAN on the video card. Located in a crowded HTCP case I could not see that the fan had a broken blade that was hitting the card cover and stopping it causing it to overheat. It would cool down enough during a restart to recover for a few minutes.

The fan blades on these cards are extremely fragile and brittle and will break at the slightest touch. Has happend, as it turns out, to many people. If your case is very tight it is difficult to insert the card and it may break a blade just by your grip ! The cover is rather loosly fitted and can compress enough to touch the blades which even protrude out past the cover a bit. Not the best design. The fan is a 4 pin unit branded "AVC Model DASA0815RZU". I couldn't find retail replacement and warranty would not cover or sell me one. Pretty crappy. Be aware and be careful in handling this extremely fragile piece.

Your card is fine. It's a bug in EVGA Precision when using multiple NV cards.

I had the same thing happen to me, on my F@H box with four 9600GSO GPUs.

I installed the newer version of Precision (after uninstalling Rivatuner), and it *seemed* to work, but it really didn't.

I set the fan speed on all GPUs to 100%, and Precision glitched, and the fan speed on one of the cards defaulted to the lowest speed, and since it was no on AUTO, it didn't rise with temp, so the card overheated (105C!), and now the card's fan rattles, because the fan bearing softened.
