Odd Palit 1080 Jetstream fan behaviour

Recently received my Palit GTX 1080 Jetstream, and I've just noticed today an odd fan behaviour quirk that I'm not sure is intentional or not.

The fans stay off when the card is idle. When the temperature begins to go up however, during the sort of "middle" temperatures (not tested exactly but around 50-60 area) the fans start doing an odd 'burst' kind of thing.

The fans will spin up for literally 1 second, then stop for 6-8 seconds. Then spin up for 1 second, then stop for 6-8 seconds etc.

This continues until the temperature gets up fairly high, at which point they start spinning continuously then.

This behaviour seems a bit odd to me, as my experience with other cards is just a gradual increase in continual speed once they start up. Not this strange 1 second burst thing.

Is this normal? Or is something up?
 
Yeah latest driver (well, just seen one has been released today, but been on the previous latest one since I installed the card the other day). It's also just started making a loud whining noise at high framerates too. It hasn't done this at all until today, coincidentally (or not so) at the same time this weird fan behaviour has begun.

It shouldn't do that bud and get in contact with Palit, as there might be a BIOS fix that will sort it.

On the contrary, this is actually entirely normal behaviour for Palit cards. Both the 980 and 980 Ti of theirs that I had did it. It's just the way they deal with lower fan speeds. Presumably their fans have a lower limit in terms of RPM, so when the curve drops low enough they 'pulse' as the OP is describing instead of spinning continuously. You can observe the behaviour both at the start and end of this video, as the card heats up and cools down:


Their new cards use the exact same heatsink and fans with a different shroud, so I'm not surprised that they behave the same way. It's perfectly normal and nothing to worry about though.

While definitely similar, at least in that video the spins are far far closer together, and actually look intended.

The fans on my card spinning for 1 second every good 8 seconds is doing absolutely nothing for cooling. Can't imagine they would purposefully implement it like this, it does nothing except make a loud noise every 8 seconds.

Also coming across articles such as this one which sounds almost exactly like what I'm experiencing.

Remember that the same cooler is dissipating a greater amount of heat with a 980 Ti than it is with a 1080. I'm not surprised that the pulses are further apart on the 1080, as the fan will be ramping up more slowly, because a more relaxed fan curve makes sense for a lower TDP. There's always the option of setting a custom fan curve and completely bypassing that phase of the fan operation, having them come on continuously at a set temperature (you'd have to fiddle with the slider manually and determine the exact percentage on the curve where this happens to know where to set it).

In any case, I certainly don't believe that it's a fault. It may be that you just don't like the behaviour or Palit's stock fan curve, so the option would be either the custom curve or just returning it and picking a different card. I remember replying to a thread not that long ago with somebody else talking about the same behaviour on the Palit 1070 getting on their nerves, so it won't be to everybody's taste. I think you'll find any replacement exhibits the exact same behaviour though.

As for the fan issue with the Founders Edition, that only affected cards using the Nvidia stock cooler (and has been fixed anyway), so you don't need to worry about that.

Thing is there doesn't seem to be any 'curve' as such at all, it's either off, pulsing every 8 seconds, or spinning at a consistent average speed.

It's more concerning me that the day I notice this is the exact time I notice this crazy whining noise, which definitely wasn't present before as I've been playing games at 120fps the past few days and literally not even heard anything from the card, and now it's a super loud buzz/whine all of a sudden.
 
From the video posted above that's the dust cleaning feature kicking in, ramps up high at first to clear the dust then settles. Looks pretty intentional that behaviour, I'm sure if it annoys you they may have a VBIOS to stop it if you contact them.

Whining will normally settle down with use, I find any card that has had whine settles and goes quiet once used over time, never had one that hasn't so far if it had it from the start, but have seen some that get worse and only a hot glue gun fixes the issue. Also extreme FPS will cause even a silent card to whine or the PSU.

Thats not my video above by the way. My seems to pulse more vigorously and and much further intervals.

Honestly right now I'm more worried about this super loud buzz/whine that has literally started happening tonight. It's really quite loud :/ sounds like slightly higher pitched hair trimmers..

But again, this is how they handle lower fan speed percentages on the curve. If you view the fan speed percentage in something like GPU-Z as the card is under load, you'll notice it slowly rising. On most (if not all) other cards, this would result in a gradual ramping up of the fan. Palit instead choose to have this weird pulsing behaviour, until a certain percentage is reached and the fan just comes on normally. Presumably this is done with the intent of it resulting in less overall noise (since the fan isn't on all the time), although I certainly agree that it does have the opposite effect and end up more noticable than if the fan just came on and stayed on. Indeed, the pulses seem to rev the fan to a much higher RPM than it actually reaches when it comes on fully.

Again, this can all be bypassed with a custom fan curve if you wish. It's just a matter of determining when the fan comes on fully, then having it jump straight to that at a temperature of your choosing (say, 60 degrees).

That sounds like coil whine to me. Certainly annoying, but an unrelated issue. If you do believe it to be the fans, the easiest way to check it would be to just turn the fans on manually with the card at idle via Afterburner (or the OC program of your choosing). If the buzz/whine is there then, you really do have a fan problem. If not, it's definitely coil whine, which sadly there's not much to be done about really. Most retailers don't consider it a fault, because it's in no way harmful (indeed it's fairly expected behaviour), but if it's really driving you nuts you might have a go at getting an exchange.

Make a video and post it, with case closed and with case open. You sure it's coming from the GPU not the PSU or motherboard ?


It is coil whine you describe if they sound high pitched and hair trimmer or crackly high pitched sound.

Can coil whine just come out of nowhere, from absolutely none to really loud and evident?

Not had to deal with it before.

Yes it can if it's a new card, wear it in a bit run something like valley or heaven benchmark in a loop, or rise of the tomb raider benchmark in a loop. Do that for a few hours to wear the components in and see how it goes from there, will take a good few hours of running in to see if it helps. OR just game on it for a while and that will do the same too.
 
Okay something is seriously up. Just fired up GTA V, which I've been running beautifully the past few days on it, and it's stuttering like CRAZY, framerate is jumping from anywhere between 150 and 40 odd. And while doing this the noise is going crazy.

Surely this is a sign something more serious is up with the card?

EDIT: Checked with another game I've been playing recently just fine on the card, Elite Dangerous. While not stuttering as bad as GTA, the framerate is definitely fluctuating a lot and overall FPS is a lot lower than it was even yesterday! Spent past few days getting FPS solid at 60 no matter what, now its way down in the 40s where before it was closer to 100.

:( all was going so well...

Use DDU http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Remove your drivers with DDU then reinstall the latest drivers and see if that helps.

Latest drivers here :- http://www.geforce.co.uk/drivers

Also remove any GPU overclocking program if you have one starting up with the system.. eg MSI afterburner, EVGA precision, etc

Just did this to try out the Nvidia drivers released today, didn't help. Also not running any overclocking stuff. :(
 
Watching all the videos on Youtube of coil whine, mine sounds nothing like them. Its a very distinct and strong buzz sound like hair clippers, not really high pitched or 'screaming' like the examples of coil whine seem to be.

Well stick a video up with a recording, you can just use a mobile phone or webcam to record it and upload it to youtube or a file hosting site, so we can download it and see the problem. Like I said before with case open and closed.

Remember to move the phones/webcams mic close enough to the card so to hear it better on the video.
