GTX 760 fan curve settings. Am I damaging the fans?

[TheSquirrel]

Hello,

I've often come to the Tom's Hardware forums for assistance this is the first time I've asked a question myself.

I recently got a new gaming rig with a 3.2 i5 and a MSI GTX 760 2gb video card. Naturally I booted up Crysis 2 and maxed everything out to see how it will handle things. It hit the 80C mark pretty quick. From reading this is where the GPU booster cuts out. It's not a dangerous temp apparently but it's higher than I would like.

So I downloaded MSI Afterburner and set a fan curve and I'm keeping it around 69-70C during heavy action. This is with the fan spinning at 80-90%.

I was curious what the long term hardware effects are for running the fan at this speed. Am I extending the length of the card only to have the fans die out on me sooner? Or are the fans designed to handle this kind of load and speed and I don't have much to worry about?

If the fan is spinning constantly at 90% or around there then yes it will slightly reduce the life of the fan, but were talking about two years minimum.

If the fan is spinning down when the gpu isn't in heavy use then it should be the same life span.

Actually, it's the other way around, lower voltage on the fans is more stressing than having them run at nominal voltage and speeds. My ASUS 780 Ti have a curve like this 50c=50%, 60c=70% and finally 70c=80%.

This is my current profile. So it does slow down to about 40% when the GPU is not under load. Should I lower that to 30? It's the default minimum that Afterburner had in but when running with the default fan settings it lowers to about 30. I guess I could just close Afterburner when I'm not gaming that way it returns to the default 29%.

Any changes you think I should make to the curve profile? I don't have it overclocked in anyway except for the built in GPU Booster (I obviously don't know enough to overclock, I'm terrified I'll fry the card).

It's a matter of taste, really. If it doesn't bother you noise wise, leaving it at 40% below 30c is totally fine, if it does bother you, just set it 30%.

Otherwise the curve looks fine to me. http://postimg.org/image/se8dwb39d/

Cool. I altered it slightly to be more like yours. Going up 10% with each 10 Degrees of heat. We'll see if it can maintain the 69-70 temp while playing during that. If it doesn't I'll swap it back to the one I posted.

The sound doesn't really bother me, if I didn't know it was just the GPU fans I'd probably freak out but since I generally game with headphones the 80-90% sound doesn't bother me. Runs rather quiet at 40%

Thanks everyone for your response, and if anyone has any more information I'd be happy to hear it. Guess this is where I'll come when I finally get up the courage to overclock it some.
