I have RX 580 Nitro which from yesterday got this problem. Usually it happens form 1100 to 1300RPM during gaming and when fan is slowing down. Is there any solution to this? I presumme if I send it to RMA I will just get the new fans not the GPU? Wher can I buy fans separately?
What program is best to set a custom fan curve (and maybe undervolt) - MSI afterburner or Wattman?? Do these two can work together?
Wattman would be the best choice, in my opinion, since it was engineered for AMD GPUs.
Check the GPU fans and make sure they are clean without any gunk or dust buildup. Also turn the fans with your finger (no power on). It should turn effortlessly and quietly. If you feel any resistance or hear any type of noise the fan's bearing may have gone or or going bad. Also check to make sure there are no obstructions that may be interfering with fan's function. like a small cable in the way of the fan's blades as an example.
One more thing to check is if the GPU card is solidly secured to the motherboard and Computer case. Possible if the GPU card is tilted slightly it may cause the fans to be slight bent causing noise when running.
Today I cleaned my case, took out the GPU out, there were some dust behind GPU fans (not much), cleaned all and I put it back in. My case is Define R5 and in default position holes on GPU and holes on case are not a aligned so I need to move a GPU a little so that screws can fit in holes. Seems after stress test that resonating noise on fans is 60% lower but need to test it more. I also in windows for the first time enter Wattman, it seems that it corrected a GPU fans curve, now it max is 1100RPM on 75C. This picture is from Aida64 stress test (all option). What is this GPU small usage spikes. Is this normal? On superposition (didn't take a picture) it seems to hold all time on 100% GPU usage.
So everything OK?
I tested now in Superposition on 1080p extreme (not benchmark, it was a game test, didn't move a mouse) around 40mn, again I got this small spikes in GPU load, is that normal?
Game loads vary a lot with Polaris due to large number of CU present. Do not be concerned.
Focus on keeping dust out of your rig.
Speed of the fans with a GPU is usually dependent on what the OEM uses for a fan and the size of the cooling fins an sink beneath it. My fans on my RX 580 while the get noticeably louder as they reach their 3000 rpm peak, I don't notice any extra resonation or vibration noise, simple the extra air of the fins.
If yours is doing that the fans could be going bad or defective. I would at least question Saphire support about it.
IMHO in general AMD does not set the fan cure aggressive enough for these cards. Many RX 580's begin to throttle in the mid 70's much lower than their supposed 90's max temp. I have to set mine to be running 100% at about 68 degrees to stay stable.
You don't want to undervolt an RX 580. This is popular with Vega and now some Navi users are reporting doing it. The architecture for Polaris is not the same and these cards are typically power starved not needing less. You typically want to set the power limit to it's max of 50 for stability.
If you have a card you have to undervolt or underclock to be stable then you are likely losing performance. This to me means it is defective and should be returned or RMA'd.
Air flow it extremely important with Polaris. They are toasters and run very hot. I don't have a glass sided case and my side has wholes and a mount for a 140 mm fan that blows right on my PCIe slots. This helps a lot. If you think that heat is a contributing factor you can take your side panel off and use a small desk fan to blow into the case and if you see things are better than you know you have a case cooling issue.
I will share the Wattman settings I use and have good luck with. My clock and memory speeds may or may not work for you.
Ok, just to be clear you know that Superpostition is benchamark tool which has Game mode where I can walk around and where gpu usage is always 100%? If yes than ok, by your answer I was thinking that you talk about general games.
I can still hear fans resonanting noise (it happens around 800rpm and 1100rpm), it still here but with less noise, to completely solve this I was thinking to buy only one replacement fan (with little luck I beliave that my gpu has one is faulty fan not two). On aliexpress I can find it cheapest, around 10$ but I suspicious are they original, in standard stores it is about 18€.
Thank you. I will contact Sapphire also to see what they have to say.
I think airflow shouldn't be a problem in my case, highest temp I seen on my RX 580 is 75C with 1300rpm. I was also thinking to activate fan in idle mode, to put it in lowest rpm. That good? With your advice I will probably give up on undervolting. Thank for the pictures but I can't see values on graphs, I will look more about it on forums and youtube videos.
Will there be any problems if I set settings in Wattman and than use Afterburner to measure temperatures and other things? Before I sold it to miners I had RX 480, right when she was released and during that time I occasionally got message that wattman settings were restored, that it crashed. But now drivers should probably be stable.
I see that your Sapphire RX580 has the Quick Disconnect feature which is you can replace the GPU Fan without removing the Shroud. I suggest you open a RMA Ticket with the Retailer you purchased the RX580 from since they are the ones that determines Warranty issues. They probably will send you new GPU Fans under Warranty if they believe they are defective free of charge under Warranty.
