Noise Problem with Sapphire Nitro+ RX 580

[DrMacintosh]

Hello, so my system has always been loud. I thought that because my case is a modified PowerMac G5 (zero sound isolation), that my case fans were what were the loudest component in my system. Turns out that last night I was able to isolate what component was making all that noise when gaming. 

 

Turns out that my Sapphire Nitro+ RX 580s fans were spinning at over 2,300rpm despite the highest temp recorded by HWmonitor being only 58C. As you can expect, this makes the card EXTREMELY loud, I'm talking louder than a reference 480! Could HW monitor be wrong about the max temperature recorded? It was correct about the temps at idle and the RPMs reported matched the ones being reported by Wattman. What is even weirder is that when I was playing before I updated my drivers is that the card took like 5min to spin down its fans from the max down to like 805rpm. Even though the card was sitting around 47C. According to everything I've seen, the Zero RPM feature should mean that the fans are not spinning completely until like 55C. 

 

Could the stock fan curve have been totally borked? From what I can tell the fans should never be approaching their max RPM with the automatic fan curve on this card. Should I try switching to the other BIOS on this card? I can't find any documentation on which BIOS is which so I have no idea which one I'm using right now. 

 

Thanks.

What does MSI Afterburner report for both fan curve and temperature?

I'd have to reinstall that. I've removed it since I'm partial to letting the cards run stock.

Ok, so it looks like the max temp recorded by HWmonitor was wrong, I mostly play World of warships and the most intense portion of the game is the port screen. Sitting there I'm seeing the temps hover around 75-80C. At that temp I'm seeing up to ~2,200rpm as described. Still loud, but maybe not as loud as my brain at 1AM thought it was. 

 

The World of Warships port is known to basically be a power virus (lol), I might do some more testing to see if I can hit these temps in other games. But it's looking like the fan curve is working (mostly). On startup the fans will remain at 0rpm like they should, but I haven't gotten them to spin down to 0 again after having put the card under load.

Stock fan curves on pretty much all video cards are way to aggressive.

 

I would recommend creating a custom fan curve using MSI afterburner, that is what i have done on all my video cards.

 

Fan at 100% RPM doesn't move 2x more air, than at 50%!!!  It is more like 10-20% more. That is why i run my fans at max 65%, running them higher just doesn't give enough benefit to justify the massive noise increase.
