I bought my card in January and its been working fine up until the last 3 weeks. Periodically on startup one of my fans would go to (what sounds like) 100% while the other 2 dont move and the 'fan stop' light is on. Eventually it would stop and wouldn't happen again while the computer was running, not even while running games.
Now though it seems to happen on every startup. I downloaded MSI afterburner and when I start the PC and the fan goes crazy I start afterburner but there is nothing there. Then I manually take control of the fan speed and the other 2 fans start, the 'fan stop' light turns off and the graph shows activity. When I change it back to auto the 2 other fans stop, the 'fan stop' light turns on and the graph goes back to no activity ALTHOUGH the other fan is still going at 100%. Then after a while it just stops.
I have a Gigabyte GA-X99-Phoenix SLI Motherboard and the bios version is: X99-Phoenix SLI F4.
Does anyone have any ideas to what could be causing this and how to fix it. It has been working fine for 4 months.
