• Radeon WattMan causes GPU fan to act erratically
    4 replies, posted
Hey everyone, I recently got an RX 480. I've had awesome experiences so far, and I've benchmarked it (although not strenuously) on the games I have installed on my PC. It's an awesome card all around, except for one problem. WattMan is somehow interfering with the fan, and I'm not sure how to fix it so I can use it normally. With Radeon Settings open, my GPU's fan idles out at 300 RPM. That's quiet, but absurdly low. When I try setting it any higher, it does -- but then drops to 0 RPM, and only wants to spin up when I adjust the settings to automatic. Sometimes it doesn't want to come back until a restart. With Radeon Settings open, sometimes my fan even hits 3000 RPM -- it's max -- for no reason. Then drops to 0. I've had this happen twice; once when coming back to my PC in the morning, the second time just out of nowhere. It's worth mentioning that having MSI Afterburner enforce a fan curve (whilst Radeon Settings is closed) seems to fix everything wrong, and the fan doesn't do anything weird. Is there some sort of way I could still use WattMan and not have to worry about the fan outright stopping on me without notice? Moreover, has anyone else with an RX series card had this issue? Thanks for any replies.

Your choices are to either ignore Wattman entirely or use it and hope it doesn't kill your card. Personally Afterburner gives you more control than Wattman as you can enforce a fan curve while Wattman can only enforce a fan scale which barely even applies at times. AMD's let the ball go with Wattman as of recently, the other option you have is to rollback the driver if you're on the latest versions, the problems were introduced with the Relive drivers. Oh and the last thing, make sure the "Chill" setting isn't forced on, Wattman really likes to do that for some daft reason.
That's a real shame. WattMan's UI seems pretty solid and comprehensive, didn't think it'd cause me problems like this. Afterburner works fine, but I don't really care for the overclocking options. Is there some sort of program that lets me set a fan curve without all the bells and whistles of Afterburner?
I mean to be honest there's no reason not to try and do a bit of overclocking. With afterburner it's quite a bit easier and safer than what you'd think of with CPU overclocking. A lot more of a benefit too.

I have to use it to set an aggressive as hell fan curve for my 290x otherwise it overheats when under full load, the original fan profile has long since been forgotten by the card and its got a dodgy fan which wont work correctly unless maxed under load and for me only Afterburner has allowed this, Wattman just murders it.
