hey guys so i just installed asus smart doctor that came with my asus gtx 570 with dcuii, i noticed on GPU-z that my gpu fan speed never went over 15% even gaming. i was wondering if its safe to have the fan speed constantly set at 30% or higher.

More about : gpu fan speed

yes its safe to have the fan set at 80% or more, in my opinion msi afterburner is a better overclocking tool and it will work with your card

ok, thank you. i was just curious if you could have it over 15%. i figured that they would have the fan speed thermally controlled, not just always 15%

it should be, download afterburner and set the fan to auto that should set it to be thermally controlled, uninstall smart doctor first though

ok will do. does msi afterburner give the temps of the gpu? and if so are they pretty accurate? lol and this asus card is crazy loud after 50% fan speed

yeah the temps are pretty accurate and it gives pcb temp and gpu temp it is pretty awesome, i got mine on a custom fan curve, silent when idle, roaring while gaming (i use a headset so dont care)

yeah, i'm liking afterburner a lot better. do you know if 35-40 celcius is an ok idle temp for my card?

absolutely fine , load temps are fine up to 90 celcius for reference, although obviously lower is better

The Asus cards are very well cooled....the ones here don't get audible till well into the 70's C .... run OCCT GPU test to see if the fan is responding.

what is an OCCT test? is i t normal to hear a buzzing noise from my computer when gaming?

i believe thats a stress test such as furmark, or kombustor, its to heat the gpu up as much as possible and watch the fan speed and see if it increases, what kind of buzzing do you mean, fan buzz or something else

FYI, sometimes fan speed controls like that override (kill) the graphics card's auto-speed function.

If left to its own devices a gpu should ramp the speed to around 70% when it heats up. Listen to your gpu, if it doesn't spin up during a game, then your "performance" software has disabled it.

This has happened to me. I had to remove all the drivers and reinstall to get the gpu back to normal mode.

the buzzing is pretty high pitched. im pretty sure its not a fan. and everything in my computer is no older than a month

Get your ear close to your PSU when you hear the buzzing sound, could possibly be a PSU gone bad

ok, i just did. its not my psu. the mobo i bought has pcie 3.0 slot and a three 2.0 slots. should i take my card from the 3.0 slot. or does that even make a difference?

It wouldnt make a difference really as they are backward compatible.

temps not going above 85/90 degrees if it does set a more aggressive fan curve

well if been playing just cause 2, with everything completely maxed out for like an hour, i sometimes get a little weird color flicker, but according to msi afterburner my temps never go over 60 celcius and my fan is usually set to 50-70%. i dont get any lag on the game. but i can still hear the buzzing. it for sure from the gpu, and it sounds like an electrical buzzing noise. but my temps never get high or anything, theres never any lag on just cause, and both lights on the gpu are green. so idk what to do.

the colour flicker could mean your memory overclock is to high, try lowering the memory back to stock, and sorry i have no idea about the buzzing,
