Hi,
After receiving my titan SC, I've been running some tests, and without Precision X custom fan curve my titan stop at 994MHz because of the heat.
So I started paying with the fan curve but I have questions.
First, I know that a lot of people will say "in 2 years you won't have this card anymore", but actually I intend to keep it for a long time, in a second rig, and that's why I went for the warranty extension (still have a running 8800GT that just passed its 5 years).
Having said that :
- Is there a "risk" running the fan at a higher speed ? will it wear out much faster, or will it be OK for 5 ... 10 years ?
- what's the best way to keep it safe ? Use a "step" kind of curve ? (for example : 40% at 30° and stepping directly to 50% at 50°). I figured this would be healthier for the fan, but what if the temp goes between 49° and 51 ° ?
- how many steps ? I use all of them right now, going from 40% to 80% about every 5 or 10°. Is it Worth it ?
If you have advice on fan curve settings .... I'm all ears !!!
Thanks !

Ish happens but we got the warranty and or you can probably find another shroud to swap it with from those selling it cause they went water cooled.
Mine personally sits around 63c peak @ 60% fan, never really seen the need to raise the fan any higher.

you're Lucky, mine was at 81° (metro 2033 in 2560 all settings/filters maximum), and the fan was running at its "default" speed of 56% .... I'm not saying puting it at 85% is the best way to go, but sure there must be nicer settings.
Good thinking about the replacement though !

Just play with the fan curve until u are happy with the temperature, That's what really matters is where your happy at.

You ought to move your curve to the left so your temp peaks at 78C. This will keep your GPU from throttling due to temps. No idea why you changed hysteresis to 10C.

My temperature limit is set to 85C.
I have the hysteresis set to 10C so the fans aren't constantly ramping up and down.

here is mine right now :  I'm thinking of having less "steps" though (and I know it can"t go above 85% but I couldn't remove the "dots" :)

You can remove them by clicking on them then hitting the 'Delete' key on your keyboard.

I got that. I was just suggesting you might consider changing that so under load you peak at 78C to prevent throttling. I realize noise my be a concern for some depending upon your case cooling. Gaming wise, my fans hardly increase past 60%.

He already wrote that he has set the temp target to 85C so it will not throttle due to temp until the card hits the 85C threshold. That's GPU Boost 2.0, Nvidia is letting us to set the temperature threshold anywhere up to 94C.

No, it doesn't actually work that way. The GPU's will still throttle around 80C. I ought to know, I've tested this repeatedly and BOTH of my TITANS will throttle a step ~80C regardless of what the temp target is set at. What the temp target attempts to do is keep your GPU from throttling as far as long as the power usage stays under limits. As far as I know every other TITAN does the same thing.

Actually, nope. 2 of my 3 Titans i got in my hands didn't throttle at 80C no matter what (of course i myself set the temp target anywhere from 85-90C just in case). The 3rd Titan got RMAd exactly because of this, throttlng at any temperature that is lower than the temp target is not normal unless i have missed something. Like i said, like you i have seen at least two of my Titans not doing that. Again, NOT every Titan does that, if you want a video i'll be more than glad to provide you one. Since you edited your post, i missed this: HeavyHemiWhat the temp target attempts to do is keep your GPU from throttling as far as long as the power usage stays under limits. Power target is a limiter and temp target is another limiter. Whichever hit the limit first will cause throttling (power or and temperature). You set the power limit to 106%. The card hit's maximum lets say 102%. You set the temp target to 90C. The card hits maximum 83C. No reason to throttle, none of the limits reached. So why throttle at all when the temp in this case has exceeded 80C? And what's the point of giving the user the ability to actually manually set more than 80C the temperature target? It's not GPU Boost 1.

Stock throttle point for a TITAN is set at 80C. Now, some might be 82C and some might be 78C but they are set to throttle at 80C.

Stock temperature target is 80C, it will throttle at 80C if it reaches 80C and you don't increase the target or take care of the temperature by setting the fan rpms. That's the normal operation for me, have/got two out of the 3 cards that operate/ed this way. Honestly i have been looking for data sheets or articles directly from Nvidia (not reviewers, Nvidia) with more details for months now. Can you provide any technical data sheets or anything directly from Nvidia that says that Titans should and will throttle no matter at a certain temperature no matter where the temp target has been set? Some might be 82C and some 78C? Specs should be firm, sorry but this doesn't make any sense to me. I have/had two different cards with even chaotic ASIC difference (#1 around 79%, #3 around 65%), none of them throttle due to temp not at 78C, 82C or even higher as long as i had set the temp target higher than that. Still, care to watch a video with my last Titan doing 84C and still no throttling? (temp target set to 94C)? That's Titan #3: http://youtu.be/iAfK4vIbL6w I have also tons of graphs showing my #1 Titan exceeding 80C without a prob (again temp target set at around 90C), sad i didn't had a video camera back then. Start from this thread http://forums.evga.com/tm.aspx?m=1906283 , you are interested only in the graphs that have max TDP less than 106% (otherwise it's power throttle). The maximum temp i hit with this card was 88C (temp target at 90-94C) and i never saw this card throttle due to temp. PS: @ LeMakisar , sorry for hijacking your thread man, we should just discuss all this in a new thread, maybe a moderator should cut these posts and put them in a new thread.
