Yesterday I picked up a gtx260(non 216) and I've noticed it's much hotter than my 8800GT(of course). The fan was on 40% when I got it and I quickly got up to low 70's when gaming. I upped it to 60% fan speed and still hovered in the 75C range, so I bumped it up to 80% and it seems to control it a bit better. My question is, I know these new GPU's are even going into the 80's(gtx280+4870 ect..), but is this going to cause a problem? I'm used to staying below 60 with my 8800gt and I'm sure 75 max is fine for my 260, just figured I'd double check.
Also, running the fan constantly at 80%, should it reduce the life of the fan/gpu? And is there a way to only have the fan run at 80% during 3d performance mode through rivatuner.
Suprisingly enough, the fan isn't that loud, I have my tower right next to my monitor and it actually seems quieter than my 8800 at 80%.
It the temperature should not be a problem at all. I have two 260's and I have noticed that during summer in Iowa they got up to the high 70's and low 80's with 75% fan speed. Now, in Michigan and cooler weather they rarely break 70 with 75% fan speed, so your background temperature matters. However, you should be fine at those temps.
You don't need to run it constantly at 80%, you can preset a "normal" fan speed and overclock and a "gaming" fan speed and overclock and simply switch between the two with a hotkey using RivaTuner or something like EVGA's precision.
must be defective fans because i live in florida and i have the GTX260 216 and it never goes above 60C at 40% fan speed. its always hot in florida. and i dont live in a cold house, its usually 75~77F in the house and my card never gets above 60C. i would check that out closer. oh and my card is over clocked like in the sig.
I've checked the fan, it seems fine, like I said I don't think it's faulty, I've got a mid tower and not the greatest airflow, so staying below 70 at 80% fan speed appears fine. I'm more concerned with lowering the fan speed when I'm not gaming without having to open up riva ect.
