GTX 470 random fan spikes?

post #1 of 7
Thread Starter 
hey so recently, my 470 spikes the fan to 70% from 50% for about 3 seconds every 10 min when idling. when under load, it ramps the fan down from 70% to 30% and sometimes stays there. yesterday i was playing bfbc2 and the fan ramped down and i thought itll go back up again, but it stayed down and eventually overheated and shutdown. Whats wrong? i reset the oc in afterburner and it still does this.

Is any other monitoring software running at the same time, such as CPUID's Hardware Monitor? If so, then that's the culprit.

only msi afterburner for the oc. Why should it affect the fan speed though?

I get it. Just to say, fan speed is limited to 92%.. which is ~5000rpm. Mine randomly goes full, which is 5400rpm (can't be dont normally since its locked) and i can also tell because its a lot louder than the limited 92%.. and it just happens randomly. Afaik it's driver related but 260.99 stopped it happening, now it has only happened once or twice maybe.

Fan control is usually something the driver controls. Try the latest driver from nVidia.

There is a history of these types of anomalies when using something such as Hardware Monitor at the same time as Afterburner, Precision, RivaTuner, etc.
