I have same problem here. Sapphire Nitro+ RX480 8GB. When under load the graphic card fan will randomly spike to full speed even though the temperature is merely 70+. It is as though the fan is not ramping up fast enough compare to the temperature, and it kicks off a safety mechanism that full blast the fan to rapidly bring down the temperature. Sometimes it will stay full speed for 10 secs, some time couple minutes. After that it will come down by itself.
BTW, it does not happen for the first 1.5 months of my ownership. It only started doing this in the recent couple weeks.
Do you already upgrade the driver to 16.10.2 or 16.10.3?
Just try that first, it should be fixed with the new driver.
I am currently on 16.10.2 already.
The problem fixed itself since driver 16.10.2, at least for me.
I'm using msi afterburner for a while now and not a single jump to 100% fan speed.
I'm on 16.10.3, and it is still happening. The only way that seems to work as of now is to run Sapphire TRIXX, and set custom fan curve that is more aggressive than the Auto fan curve, in order to keep temperature around 80.
If you already did it then skip my post.
Try to report it again to AMD Issue Form .
In my case with Powercolor RX460, the new driver(starting from 16.10.2) really fixed the fan 100% issue for me.
I reported the issue to AMD too every driver release before 16.10.2.
Since AMD has the clue on this issue for some cards, it should have high chance to fix it for your card if you report it.
Unless it is a fault card.
Just my two cents.
Even TRIXX is not working. The fan starts to spin up to 100% at 75C. Going to log a issue.
DDU in safe mode then install 16.11.2
It doesnt sound like you have an issue, 75C is a lot, and it probably should go 100% on that temperature. Most people use custom fan curves becuz default curves are usually really bad.
People in this thread had their fan jump to 100% at 30C for no reason, and that has been fixed since few drivers ago.
Have you guys check if theres a Bios update for your GPU?
And if your GPU maker has a software to control the GPU, try installing and using it and check the fan control in their app to see if at least can make a temporary fix for that problem...
I have a Asus Strix RX480 and never had that problem. Also I have Asus Tweak II latest version installed and I can set manually the fan speed to the % I want, and it keeps on the same setting 4 ever...
In the 16.10.2 release note AMD said this:
Fan speed may sometimes remain elevated on select Radeon RX 400 series graphics products even when an application has been exited.
So it may be not all affected for all AMD RX400's card.
Also as far as I know, I own a Powercolor RX460 card and Powercolor never release any so called bug fix or new GPU BIOS for their AMD cards.
Only an exception is an unlocked BIOS to unlock PowerLimit for Powercolor RX480 red devil , but it still not a public release on their web, only in DevilClub.
This issue(which is dxva + GPU Fan monitor APP caused Fan 100% and lost control issue in my case) is a driver issue as far as I know for past 2 months.
Mine is a Asus Strix RX 480, and I updated the bios twice already. Its on 1.02, it seems then that Asus usually updates their bios more than others...
Anyway doesnt powercolor have a app like Asus Gpu Tweal II?? Maybe you can use it to temporarily fix the problem by using manual fan control
Thanks for the suggestion but my issue has been fixed with the new driver update.
Powercolor do not provide any build-in GPU APP so I use MSI Afterburner.
I've had this problem with THREE amd cards...
My first was 6990 which the fan controller eventually stopped working on completely destroying the card so this was probably a hardware failure and not software. (Ez RMA)
Second card was the 7970 which also did this from time to time. (on startup though and not randomly while using the PC)
Now I have a Fury X and this one is the worst thus far.
On the 6990 and 7970 this happened less than once a month. With the Fury X it happens atleast once a month sometimes more and it happens randomly.
It's obviously a driver bug. I can start something like MSI afterburner and bring the fan down. But as soon as I stop it and go back on the driver it's at 100% again.
It's not really a big problem for me personally but NOT KNOWING why it happens is driving me nuts.
