Zero RPM is normally enabled on Radeon Software by default (unless you tweak gpu settings), however I've set it so that when I start playing a game the feature is disabled because I find my gpu fans to come on, reach it's Zero RPM temperature set point and than turn off and than on again and off again. Depending on the game of course, if it's a really demanding game than they usually stay on much longer.
My gpu is an Asus ROG Strix LC 6800 XT (aio) and I've replaced the 2 aio fans with 2 Noctua industrial 3000 rpm fans so they're nice and quiet. When I'm not gaming (Zero RPM enabled) the gpu runs at 53C/57 junction (aio pump always stays on, fans off), if I disable Zero RPM altogether it's 25C/30 junction.
I guess my question is, should I just disable Zero RPM altogether and just let the fans run all the time? At first I thought that Zero RPM may prolong the life of the fans by them not running when not needed but with it enabled the fans are usually cycling off and on when gaming quite frequently and imo fans take more abuse when they come off and on rather than just run. I do use my computer quite a bit so dust is a bit of a factor but I usually do maintenance regularly on my pc. What do other people do?

if your AIO fans also double as inlet/exhaust, I'd let them run all the time at their lowest speed.

I have the same issue both on polaris and navi2
if I set the desktop to 144hz, the polaris get hot to 55c and the navi over 60, so like you noticed the fans are spinning every 3/4 minutes to keep the card under a certain temperature, then stop, then the card gets hot again, and all of this is repeating for all the time
setting the desktop to 120hz solved the problem as the polaris goes down to sub 45c and the navi2 in sub 55c, this due to the lower clocks of the vrams
I prefer the solution of the fans not spinning all the time as I think that they will last a little more
ID: h0wtllkID: h0wuo8win non demanding games (or capped to X frames/sec) is the same thing
if you set 165hz in desktop and you haven't the fans spinning looks like your vrams are in energy saving mode, you can see this opening gpu-z and looking at the vmemory clocks
ot: you can set the words under the nickname in every subreddit, in the right menu, look for set flairs
ID: h0yl7ozAnd this is why I am going to miss my Vega 64. It's so efficient at idle at any monitor refresh rate. :/

I turned it off, when idling they are pretty quiet, can't hear them over case fans. My thoughts are it's probably better for longevity to keep them running than start stop.
ID: h0wregwYeah it's pretty quiet. I only have 4 fans running on my pc. I have a 240 aio for cpu mounted on the top with 2 fans in an exhaust configuration and the gpu aio in the front with 2 noctua fans as intake configuration. The gpu itself has a blower style fan that cools the vrm but that doesn't spin that fast and is pretty much inaudible.

just lower your fan curve to make the transition from off to on smoother
ID: h0wq6eeI second this.

I hate it and disabled it because it was annoying to periodically hear the fans spin up. It was as if my card had sleep apnea and would stop breathing for a time, then suddenly gasp for air, then repeat. I don't see the point of Zero RPM if all that it takes is a few minutes for the card to heat up enough that the fans have to kick in again. I'd much rather have the fans always running. A low RPM that produces a steady hum not much louder than the rest of my case is preferable to that hum going away, then coming back, then going away, then coming back.
-
Is there a way make this setting persistent through "crashes"? Mine resets all the time but the fan curve is the only custom setting I'm using. My PC reboots from time to time at idle; working through OC and PBO2 stability at low/idle workloads. Every single time I need to manually set my fan settings.
ID: h0xw86dI don't think so. A crash will generally revert back to the default settings and Zero RPM is enabled by default. Getting frequent crashes isn't good though.

I have zero rpm disabled and just keep the fans on the lowest speed in the Radeon software.(15 speed is around 650-700 RPM) I have a 6700XT and its sitting at 30c idle compared to like 40-45ish with zero RPM and I don't hear the fans at all.
-
I would rather let my fans run at 400-800 RPM all the time than keep the GPU warmer and reduce airflow in the case. That's what I do. 500 RPM all the time until 50c+ and you can't hear it at all.
-
imo the 0rpm on its own is stupid. You cannot hear a 120mm at 600rpm in a case. Especially not anything smaller. The noise floor of the room will be much higher 99% of the time.
Especially since its an aio running the fans even at low speeds would increase case airflow, which is generally useful for lesser components.
The gpus run hotter for no reason at all. It should be opt in, if they want to have that feature.

I disable zero rpm because when it’s enabled you basically have a 50-60C space heater inside your pc. For me I noticed that my x570 chipset was running 10c hotter when zero rpm is enabled. I also suspect it has a small impact on cpu temps. Edit: *in as in inside your pc...
ID: h0xhyi9The card produces the same amount of heat regardless of if the fans are on or not. The fans disperse the heat, they don't prevent it from existing.
ID: h0xlfr4The fans disperse the heat so that it can be exhausted out of your case thus reducing the heat inside your case. With zero rpm your gpu and heat sink will be allowed to get hotter and the heat won’t effectively be exhausted from the pc.

Fans still=less dust in the radiator.

@OP This isn't a problem unless your card has a bad fan curve. The only solution is to set a better fan curve. That said, AMD disables Zero RPM when making a custom fan curve, so you don't even have the option to get both, so Asus screwed your card with bad bios defaults. I had similar issues with gigabyte, but not powercolor. Seems like Asus is on the avoid list now too.
ID: h0ye9cuMaybe I didn't explain it correctly. When Zero RPM is enabled my fan doesn't go on and off when I'm not gaming. It stays off. It's when I'm gaming that the fan will come on to cool the card and than shut off when it's satisfied than on again when the temp rises again. Even with a 2.7ghz this card will maintain 50C no problem.
If I'm playing a demanding game like RDR2 or Flight Simulator the fans stay on since the load is bigger than playing I don't know Dishonored 2 or something. It's not an issue that's effecting my performance or anything my post was mainly to gather some community opinions and find out if others keep this feature enabled or disabled. Personally I'm very happy with what Asus has put together here. The performance is fantastic, with my highest OC I've got 20358 graphics score on Time Spy so there isn't any concerning issues as far as what it delivers.

The only thing AMD really needs to implement is a slider for zero rpm cut off without having to bother with a fan curve. Literally just an option that lets say doesn't allow you to set it much higher than 65C for example, but allows you to drop it to 40C for example. Whatever you set the zerorpm slider at, that is the temperature the gpu needs to hit before the fans kick in... rather than flatout disabling it.
While i personally don't run into a problem majority of the time even with multiple 4k displays attached, the fans usually never ever ever startup until i kick a game on. I suspect due to my choice of cases and fan placement in the machines that i build for myself and customers allows for the gpu to remain under the threshhold.

I own an rx 570 and my brother owns an rx 470. Zero RPM causes them to crash when web browsing. All I can figure is the temperature gets too hot to fast.

3700x - RX580 Sapphire
I'd like to clarify that the fan cycling off and on happens when I'm gaming (not too demanding games) if I'm just using my computer, browsing the web/watching YouTube etc with Zero RPM enabled the fans never come on with Windows set to 165hz.
I'd also like to ask a question if you don't mind. How did you set "3700x - RX580 Sapphire" to show up next to your name? Sorry I'm new to Reddit.
