    Asus Strix 1080TI fans ramping up and down, please advice

    Hi!

    Just installed my new Asus Strix 1080TI graphic card and are experiencing "problems" with the fans. At auto fan speed the fans ramp up and down from 0rpm to 900rpm every other second at a certain temp. I know the fans are standing still up to a certain temp and mine does aswell but this ramping up and down cant be normal or is it? If I set a user defined fan curve the fans are doing the same ramping up and down as long as I dont choose 30% fan speed or higher. Anything lower than that and the fans are doing the same up and down thing.

    I really like the card and dont want to change brands, Is there anything I can do about this other than setting a fan curve that starts at 30%? Is my card faulty?

    Hello Jaxione83
    That doesn't sound about right. Have you updated your drivers?
    Does the same issue occur when installed on a different computer?
    If the problem persist, please return your unit to your retailer and ask for a replacement if you can
    Or send it for repair. Our engineers will sort it out for you. Thank you

    Which software are you using to control your VGA fans?

    Hi!

    The stock fan curve does two things wrong.

    1. It is lacking fan hysteresis which means that fan speed goes up and down if the temp stays at the temp set in the fan curve. For example if the fans are set to start at 60 degrees and the fans start and gets the temp down to 59 the fans will start and stop and start and stop and so on because the temp is flucuating between 59 fan off and 60 fan on. Normally there is a few degrees of tolerance set in the fan curve to stop this annoying on and off thing.

    Are there any bios updates for the 1080ti strix that can fix this? I fixed the problem myself by installing MSI afterburner to set a custom fan curve and fan hysteresis.

    2. The fans does not work properly under 17%-18% setting the fan speed below this will make the fans do this stop and start thing. Have checked with other ppl owning this card and theirs do the same.

    So is this fixable by firmware?

    Got it to work ok with MSI Afterburner, see my reply in the previous post. Seems Asus has been sloppy in their default fan curve.

    Angry Same problem here

    Got my ASUS ROG STRIX GeForce GTX 1080 Ti 11GB OC a couple of weeks a go.
    As you all know it is an absolutely amazing card performance wise.

    However I have the same problems with fans ramping up and down. Form completely off to 900 RPM every other minute when the temp hits 56,6 C and then turn off again as soon at temp goes below 56,6 C due to no hysteresis in the fan curve.
    This is just bull**** and unacceptable for one of the most expensive and high end cards on the market.

    I have a, to the ear, a completely silent case in normal office work, yeah..I spent more then a few dollars on Noctua fans. So not only is ASUS GPU fan control an insult to customers. The fans them selves are noisy, small and with high RPM.
    The effectiveness of the fans can also be questioned as idle temp is 56,6 C and temp under load is in the high 70's C.

    So the solution was to send some additional 50$ on 2 x 120mm low profile Noctua fans.
    Got rid of the junk ASUS mounted on the card, 15 screws in total.
    Mounted my two Noctua with zip-ties and connected then with an Y-cable to the motherboard.

    Why connect to fans to the motherboard you might ask. Because the people at ASUS developing the software for their motherboards are actual professionals and since the GPU is visible in AI Suite 3 it is a good option.

    So now I control the fans with software not developed by some internals and have accrual good fans on my GPU.
    Idle temp is now at 40 C with constantly very slow spinning fans and again completely silent to the ear.
    Full load temp with Furmark for an hour+ is 69 C, and in games both 4K and Vive VR around 58 C, fans never rev up over 70%.

    Is it really what to expect to from ASUS that you need to ghetto-mod your 1000$ GPU just because they cheap out on the fans and salary for the developers?

    @Nemorath , I have the exact card and my idle temps, with fans NOT spinning is in the low 30's
    Most likely you setup the Power management mode to Performance, which will cause such high temperatures with no load. Set it to Adaptive. I had the same problem.

    Now, I do not deny that the fans are noisy and I was thinking of modding them also with some noctua fans and also that the lack of hysteresis in the fan curve is problematic to say the least.

    Same card too. I've read the fans were supposed to turn off at low temps, however the fans are always on for me at 35C idle. The only fans that turn off are my 2 case fans that i've connected to the card.

    How do you get 24C min? I never get below 32-35C even on stock!

    24 deg. Celsius was the temperature when the computer started. Here it is still winter, so ambient is a bit chilly.
    As you can see, average is 30 deg. Celsius.
    My Noctua case fans might help a bit also.

    For turning off fans have you installed GPU Tweak 2?
    If yes and fans still run all the time, I heard there are two official BIOS versions: one for silence and one for performance.
    Maybe you got the performance version which might spin the fans all the time. I say "might" because I am not sure. I have not changed my BIOS.

    Thanks for the info. I'm only running Afterburner as i want the OSD when gaming, and i hate XSPLIT. But i will download GPU Tweak 2 and see if there's a setting.

    My card is the "Gaming' 1080ti - i've read there's an OC version of the card, but i don't have OC branding anywhere so assumed it's the general version of the Ti.
