So once when you hit 60c I think 12mhz goes down. To avoid that I set 70% fans at 60c and at 70% temp can't go further but there is a problem. Every 15 seconds fans are turning on 70% and then once when gpu is under 60c, 59 or 58 fans are going to ~40%. Then again in 15 secs gpu reach 60c and fans are on 70%.

Can this constant change damage fans ?

Yep. It probably won't go above that temperature with the Windforce cooler. If it were a reference design, it would go directly to 84c and stay there, adjusting fans, Turbo Boosts, and voltages to maintain that temperature.

And here's your G1. Important to note that the Turbo Boost algorithms are the same for both cards, and the GPU's thermal design is identical.

Looks like this might be a thing, I dug up this thread over at Overclocker.net:

980Ti Low Temp Throttle

At the end of the discussion, it seems like the workaround is to modify the BIOS. Seems awfully low to throttle at.

I wonder if GigaByte has a new BIOS for that card. My GTX 980 doesn't throttle at 70C, you'd think Maxwell GPU's would have a consistent throttle temperature. My graphics card is made by ASUS. I sit at a consistent 1316 which is stock for this card, but it's factory overclocked.

Agree, even in benchmarks. Thing is with 50% fans I'm reaching 70-71c in one loop of Valley, I can only imagine that it would reach 75c in 20c room temp once when I play demanding games for hours. So at one point I will need to put 70% fans to stop rising of temperature which is in worst case scenario 70c for me. Now If I do that for 70c It's gonna happen in same way. Perhaps loudness between 50 and 70% is way too much so I'm getting worried about fact that one of the three fans might get broken or something.

I realize this may be shocking, but your card was actually designed to run optimally at 84c per its turbo boost algorithms. To confirm, check your Temp Limit variable in Afterburner or whatever you are using to set your fan curve. You really have no problem and are unnecessarily forcing a lower temperature than your card was designed for.

Your temp limit is the point at which your card will dial back its turbo boost clocks back to stock speeds. Below that temperature limit and your card will increase its turbo boost speeds. The temp limit is manually adjustable as part of your overclocking approach.

So basically GPU is giving me "free" performance boost until 60c and then it take it away from me ?

1524mhz core, 1.242v, as soon as hits 60c I'm getting 1512mhz core and lower voltage. I'm aware that that is not huge performance loss, in fact barely noticable at all. But that is normal ?

Also what fan curve would you recommend to me for this card then ?

This seems prevalent to the 980Ti and the Titan X, but not all Maxwells. For me, I've got a GTX980 which turbo boosts to 1316MHz and doesn't budge in the temp range that it works. I see high 60's to low 70's in KF2 with VSYNC disabled. Haven't gotten my card warmer than this, but I'm guessing my thermal throttle is in the 80's.

I guess I can leave auto fans on then and be at around ~70-72c, that should be considered safe ? Assuming that it's better to do that then having 70% to 50% and other way around every couple seconds just to keep 60c cold temp..
