Insufficient fan power settings on EVGA 560 ti?

[mmaestro]

Hey all. I've been a tad concerned about the stock fan settings for the EVGA 560 ti I have in my system. Under load (furmark), temperatures climb pretty quickly up to 90C and hover around there, but the fan rarely goes over 50% power even at these high temperatures. I had a fiddle with fan settings, and if I crank the fan up to 100% power the temperature's some 20C lower, so the problem doesn't seem to be case airflow. I set a fan profile using EVGA's precision software, and for the most part the fan rarely gets over 75% and 68C in real world use (Civ V, before it was hitting 88C in the same game), but it's noisy at that level. I know the GPU will withstand temperatures of up to 99C, so should I just switch back to the stock profile and stop worrying about it, or is it better to try and keep those temps a little bit lower?

Using an NZXT Guardian case with 1x front 120mm fan moving (by the other fans NZXT sells) 40CFM, 1x side 120mm, 1x rear 120mm and 1x XFX 140mm fan moving 60CFM. I'd been thinking of switching out the front and side fans for Antec Tricools moving 79CFM, would that likely help?

Thanks.

.....I know the GPU will withstand temperatures of up to 99C,....

Are you sure about that? 90c sounds like dangerzone.... 99c honestly sounds like too much. I seriously doubt GPUs can run 99c for prolonged durations without suffering horribly for doing so.

I dont like seeing my card hit the 85c..... id close the application, if it got anywhere near 90c (ei. furmark or such).

Do you have another card occupying the slot next to the video card? Also, what's your ambient temperature?

Straight from the horse's mouth (max temp at the bottom)

No other cards in the case, ambient is anywhere from 22C to 25C, last night when I was playing with fan settings I was getting a reading inside the case of 23C, the same temperature as the room. Side fan is blowing straight onto the card.

That's weird. Did you do any overclocking?

 

[mmaestro]

It's the FPB card, so it's got an out of the box OC, but a small one. Like I said, what's weird to me is that it's clearly capable of getting the card cooler, it's just the fan doesn't increase in speed to actually do so.

Unless you bought the card to play Furmark, ignore it.

How does the card behave using it the way it was intended?

Oh, it seems to run fine except for a couple of instances where textures got all messed up that it hasn't repeated. I was (and am) just concerned because the temps I'm seeing seem so much higher than everyone else's. While Furmark hits between 90-92 on stock settings, Civ V is only a couple of degrees lower, so if that'll cause some long term damage and is to be avoided, I'd like to know.
