I got annoyed by my stupid card spinning the fans to obscene speeds despite not being over 70°C or something like that, and thought a custom fan profile will do the trick.
Heh, wrong.
For one, I don't know how 50% of 3200 rpm (100% according to the software) is 2000.
Two, the damn thing is still having a mind of its own. There seems to be a hardcoded temperature of 69-72°C (not sure exactly), which is the point where the card starts ramping the fan speed up no matter the settings, even if I set flat curve of low speed for testing purposes. It looks like a hardcoded temperature limit the card tries to keep at any cost, any settings.
I feel like there might/must be bugs somewhere because the moment I change whatever setting and click apply, the fans instantly stop, only to start slowly ramping up again.

Anyone has any experience or intel about this? I'm starting to lose it here.

It is also reacting to the junction temperature.

Try to keep the fanspeed under the 45%, like P1 26%, P2 32%, P3 37%, P4 40%, P5 45%.
P1 30C, P2 50C, P3 65C P4 72C P5 77C.

What's junction temperature?

I thought the points on the graph are temperature points at which the card switches to different fan speed. What seems to be happening is the card doing something by its own once temperature reaches specific value.

AMD cards have a bunch of temperature sensors across the entire GPU die. The junction temperature is the hottest temp detected by at least one of those sensors.

Basically it seems like no matter what I set, the fans will eventually go to the maximum speed defined on the curve. That's friggin useless.

I swear the Radeon software is just bugged.
There is no good reason why the card should do this on fully automatic/default settings.

Why the hell should it keep spinning up to 2000+ rpm even once the temperature stops at 71°C and not go below 1800 again (which takes like 5 mins rather than simply dropping relatively quickly)?

Can you make a pic from the fan curve?

You have to manually set your fan. You have it on auto.

I used to have the same card - it's currently in my brother's rig after I upgraded to a 5700 XT in Nov 2019. I don't recall any weird fan curve behavior, although I also wasn't using Adrenalin 2020 drivers. If I remember correctly, it used to max out at around 75ish degrees C, so it wouldn't surprise me that the fans are cranked when it's around 71.

It does have dual BIOS, so you could try flipping the BIOS switch to what I believe Sapphire calls their "Silent" BIOS. Might have a bit of a less aggressive fan curve. Could also try setting a fan curve in MSI Afterburner if the one you're setting in Radeon Software isn't sticking.

new AMD Cards only have their fan speed linked to the hot spot temperature. not the average.

No, it's on default.
You have to manually set your fan. You have it on auto.
Manual barely makes any difference at all, it basically ramps up to 100% no matter what, only now you can set the max.

What I'm saying is the default state cannot be working as intended. That's nuts.

The card's BIOS (both of them) have target temperature set at 75/76°C, so it doesn't even make any sense for the card to start ramping the fans up (significantly that is) starting around I'm not sure, 67 or so.

That looks like none of the cooling software is working as your card is not being controlled but running at full throttle for no reason. It has to be something to do with the OC settings. Even if you manually tune the fans it will not solve the problem. You may need to flash your BIOS. Maybe try updating the chipset drivers and it might reinstall the Graphics software properly. That is weird though

What cooling software? I am talking about the Radeon control panel. None of the cooling software? There are not multiple such programs.
The card is NOT running at fulll throttle just like that. I described the behaviour in full in multiple posts, read them again.
There are no OC settings whatsoever.
Dude I see you're trying to help, but it seems like you didn't read a single post here, and these random suggestions about flashing BIOS or updating irrelevant drivers are just nonsense.

I'd suggest you try lowering "Max Fan Speed" to 2000 and "target RPM" to 1800 in the card's BIOS with everything else default. That should solve the problem if you know that your card doesn't need more than 1800 or 2000 RPM, or is never much above 70°C GPU temp.

I think you're on a hiding to nothing here and it's gonna do what it wants regardless.

By the looks of it, a quiet card is important for you as it is for me.

If the following is possible for you, then I think you should get an MSI Gaming X Trio card of either AMD, or NVIDIA (my preference, see specs) variety. This range of cards has one of the quietest coolers on the market and even when the card is running maxed out, will make virtually no noise, see TPUs reviews of them. W1z is always really impressed with these coolers.

The problem is the fans ARE quiet, but only up to specific speed range. I mean every fan starts to get noisy at some point.
I don't think it's the cooling of the card that's a problem, rather an implementation of the fan control in the driver. I mean the BIOS has target temperature of 75°, and the card never ever comes even close to that.
Editing the BIOS is a last resort which I'd like to avoid unless I have absoltely no other choice (which seems to be the case indeed)
You're hitting a temp over-ride on something secondary, a junction temp on the GPU or VRAM
I don't know. I even installed Argus Monitor so I can control case FAN by GPU temperature, because you can only set the CPU and some random rather useless board sensors as sources. That kind of did something (even if it didn't seem to lower the GPU temps), because now I get a lot more really hot air being pulled out of the case. I don't think there's an overheating anywhere though, because the heatsink on the card seems to be really decent, covering the memory and VRMs (I believe) too.
I'm checking the behaviour again today and the FANs are already spinning at ~1200 rpm when the card is at just 59°. That's crazy! It stays at this speed until 69°, then start to raise again a little.
That's with BF4 running and on the server browser page.
For some obscure reason, when I load the test range, the temperature of the card stays the same, but the FANs spin up to 1700 rpm while the card drops to 64°.
This is some illogical shit and if I had the money for a different card (and there were any on the market, new or 2nd hand), I would probably replace it with something newer.


P.S. All the card sensors report the same temperature, so I think the heatsink indeed covers all of the important components.

I'm checking the behaviour again today and the FANs are already spinning at ~1200 rpm when the card is at just 59°. That's crazy! It stays at this speed until 69°, then start to raise again a little.
Is this a new card? I know for a fact the Nitro+ RX 580 has fan-stop. As aforementioned, I don't have that exact card anymore, but my Nitro+ 5700 XT also has fan stop, and I just checked that fans are indeed stopped when the card is idling (just sitting at desktop). This is using automatic fan control. Temps start at 50C (both GPU and junction temp) and slowly climb as the system heats up. Fans kick on initially at 59C (again, both GPU and junction) up to ~1500 RPM, which almost instantly kicks the temperature down 4-5 degrees. When it hits 50C again, the fans stop, and the cycle repeats. Temps approach and then hit 59C, fans kick on to cool the card back down, and stop again once the temp drops to 50. This is default vBIOS behavior, not the silent one.

Wouldn't surprise me if 59C is the point at which your fans kick on as well. If you're not happy with the large shift in fan speed, disable fan stop and set a lower fan speed on constantly. This'll result in a less drastic change when the fans do ramp up which will be less noticeable than fans off to fans relatively high.

but the FANs spin up to 1700 rpm while the card drops to 64°.
If the temp stays the same, and then the fans kick up a notch, it would make sense that the temperature drops due to the higher fan speed.

For one, I don't know how 50% of 3200 rpm (100% according to the software) is 2000.
Radeon Software denotes that the percentage is PWM, not percentage of max fan speed: "Fan Speed(PWM(%))"

Why the hell should it keep spinning up to 2000+ rpm even once the temperature stops at 71°C and not go below 1800 again (which takes like 5 mins rather than simply dropping relatively quickly)?
Maybe the point where 1800 RPM is the target is lower than what the temperature immediately drops to after the fans ramp up to 2000 RPM

I feel like there might/must be bugs somewhere because the moment I change whatever setting and click apply, the fans instantly stop, only to start slowly ramping up again.
Just checked myself. Card temp was 55C which under automatic control results in 0 RPM. Enabling manual fan control and applying the curve instantly cranks the fan up to the respective Fan PWM % denoted by the curve. I did just notice that swapping back from manual to automatic didn't automatically re-enable fan stop even though the slider gets hidden. Card temp was down around 39C and fans were still spinning at ~1400 RPM (speed denoted by the curve under manual control) until I opened the manual tab back up, re-enabled fan stop and applied the changes.
