I recently bought a new system along with Gigabytes GTX 590 and it has been working just fine, except for one weird thing that occasionally happens.
Sometimes for no reason, the fan will just instantly go to 95% to then slowly drop down to 40ish again, at about 1%/sec.
This happens for no apparent reason and I only notice it when the card isn't under any load. I can just sit and browse the web, doing nothing demanding when it happens. I use MSI Afterburner to monitor(not changing anything, happens with or without it on) and I see that the GPU usage is at about 2% and the temperature at a steady 45/65 degrees when it happens. It might happen under different circumstances, but not as far as I've noticed.
I've tried different drivers but this still occurs no matter which I use. Currently I am using Nvidias latest driver, 285.38. This doesn't happen regularly though, happened two times today, but before that it hasn't happened in a week. It's not a huge problem but it gets me worried since I have no clue to what's going on.
So does anyone know why this is happening?
Sorry if this has been answered before, but I couldn't find it using search.
