Okay guys, I have a Nvidia GTX 770 ACX. I recently overclocked it and its not bad but kinda worried about the temp it can reach as high as 86 but it usually around 84 at full load on unigine heaven. I started to mess with the fan curve and put the fans at 100% starting at 70c this caused the temps to drop all the way down to 76c. Now my question is which would be better/safer? Having the fans on auto letting the gpu reach 84-86 or having my fans on 100% at 70c and letting the gpu reach 76c.

don't ever use auto fan setting with overclock and your card can handle 98 C but i wouldn't recommend reaching that because it will reduce the card life and excessive heat kill electronic , whats your room temp btw? and it should be fine between 70 S temp avoid high 80S
and make sure you got the airflow setup right

If the fan noise doesn't bug you I would just leave the fans up to 100% on the fan curve like you set it to. I have both my gtx770s overclocked and have the fan curve at 70c at 100% also :). they usually dont go above 70c. Good old headphones cant hear any fans.

On a side note: The only thing I have found that will raise that temp is the business hanger module in Star Citizen. It will go up to 75c but that's probably because the game is unoptimized and must have some major gpu over usage. all the other Hangers don't have that problem which is odd but thats Alpha.

not exactly the room temp but its very hot in here. So would the 100% fan speed at 70c+ cause any damage to the fans? and i dont know anything bout airflow really all i did was hide all my wire behind the case so it was out of site and didn't block any air other then that im not sure what to do.

ya unigine heaven and crysis 3 put the gpu temp at 76c i haven't checked others. No the sound doesn't bother me much can't honestly here it over the tv or even my speakers. just more worried about the wearing down of the fans more of the actual noise lol

airfllow is the how the case handle the air inside there should be fans getting air inside the case and fans that should take the heat from inside the case to outside , your case should have the front panel get the air inside and back panel fan and the up fan get the air outside , the fan on the side should be getting air inside the case , and that depending on the cooler you have for the cpu , , dose your case has intake holes at the bottom ?

yes the front fans suck air in the top and back blow air out i have no side fan and no there is no intake holes at the bottom.

I was messing with the fan curve again this time i got it to 78c with only fan at 87% is this better? the temp is around stock a little under and the fans aren't being pushed 100% (mind u this is with the gpu usage maxed heaven and crysis 3)

it's okay one thing that i notice , if there is no intake holes inside at the bottom then why did you install the power supply fan facing down? what type of power supply do you have?

the case is design to make the power supply fan work as intake to , within inside the case unless you have holes @ the bottom so with your setup the fan of your power supply doesn't suck any ! and by that we removed it's purpes , the way antec design it to maximize airflow , i would also get another 120 mm fan to mount on inside the case next to the hard there already room for that would help with keep air around gpu and psu taking heat from bottom of the case and the up fans taking the heat from cpu

well it was my first build but when i upgraded everything i noticed i had it installed wrong i just never fixed it cause i was scared it would fight my gpu for the air. and i really don't have much room that i can see my side panel is completely touching my cool master cpu fan i had to cut one of the plastic gribs that hold an aftermarket side fan off because it wouldn't let me close it without touching the cpu fan.

but i have been testing the fan curve a little this time i ran heaven twice and the gpu temp didn't even get past 77c and i had the fan curve set at 80% from 70-80c. is the the gpu fan at 80% or should it still be a little lower?
