Re: rx 480 fan going to 100%

Hi

From what you descried I wonder there are 2 different type of this issue.

Type1: Only Fan speed screwed. In this case user still have the ability to set it back by software like wattman.

Type2: Driver crash. Although it seems Windows still working but no way to stop the Fan until reboot. Sometimes if one launched another GPU tweaking APP the display driver will just give a BSOD.

I alerted Fan's target speed from wattman to 2800RPM instead of default factory setting which is 2400 RPM. When type2 issue occurred it's speed is 3XXX RPM. Type2 is more like a display driver crash although you still can do operate on Windows but no way to stop the Fan speed.

I do not know what type will happen, it is randomly. but if I use DXVA enabled player(MPC-HC+LAV etc.)+game+msi afterburner in background then type2 happens more often from my experience.

I still have to say If I do not use DXVA, it seems works fine even I use msi afterburner whole day in background.

Re: rx 480 fan going to 100%

It has something to do with pixel shader when watching a video. When I watch a movie with sharpen image fan bugs out after some time, if I dont sharpen the image then I have no issues. I see a lot of people are also complaining about decoding not working properly so i assume it has something to with that.

Re: rx 480 fan going to 100%

  • Same issue with Gigabyte RX 480 G1 8GB.
  • Flashed F5 BIOS in safe mode/normal (normal mode first as i forgot about safe mode) Windows 10.
  • But no way to verify if my RX 480 is actually on F5 bios.
  • XTreme Engine from Gigabyte says it is F2 bios but i clearly flashed it (notice the Xtreme engine software is older than F5 release day be almost 1 week; maybe why?)
  • My Reddit post about the same issue, go support it!

Same issue

Certainly a driver problem. I spend 12h a day on linux and it never happen. Only on windows.

Re: rx 480 fan going to 100%

This happens when i watch the movies in mpc-hc player. I think that is afterburner related issue.. or not.

Re: rx 480 fan going to 100%

amdmattray_m​ please look into this problem and maybe that is the issue ? As most of us aren't having this issue but during idle or playing videos (with hardware acceleration)

Yes, i confirm its definitely sharpen shader. I also notice when i watch twitch streams gpu clocks drops to minimum
