Zero Fan Mode GPU

[delshay]

Has anyone able to run or is running "zero fan mode" on they card. The reason Im asking is I've just modded an old card R9 Nano & in open bench test idle it reads 44C. Test is not completed as I need to see temperature when card is placed inside a closed case.

Zero fan mode you should be able to surf the web & watch Youtube videos. If you are running zero fan mode, what are your temperatures.

When doing nothing my GPU sits at around 40c, then when watching youtube it can spike to 49 / 50c.
My fans kick in when the GPU hits 60c

Same as above. Most modern cards run Zero RPM at idle. Pretty much anything with a reasonable for its TDP heatsink will run in the range of 35-40 at full idle (so fresh boot) and 40-50 on web browsing/videos. That’s in a case with decent airflow, obviously. On my card fans kick in at 62C and I don’t think I ever saw it go above 75-ish even in the heaviest scenario I’ve witnessed (starting level of Ys IX, weirdly enough, due to how much of a mess it is code-wise).

Thanks, that's useful information. I never knew modern cards run zero RPM by default. It's kind of disappointing because I don't expect modern card with large heatsink to hit anywhere near 60C. Watching videos here only pulls around 12W. Can you show post set-up where I can see voltages at each state? I want to take a closer look.

This first pic is from doing a restart and letting it sit idle for a few mins.

And this second pic is while watching youtube after 10 mins.

Temps will peack at 50 when loading up and looking through my steam account stuff.
Hope this helps.

Forgot to say the GPU is also overclocked.
+100 on the core and +1000 on the GPU Ram with power limit set to 110% and temp limit set to 90.
Looks like the GPU volts stay the same for me when idle and just watching youtube.

No I want to see AMD Adrenalin/Nvidia or Afterburner software advance clock/voltage settings for each state.

Ahh sorry, any tips on how to get all that to show up?

You do realize that every TPU GPU review comes with that information nowadays? No need for the forums on this one.
Like here, on the latest 7900GRE review, end of the page in the Clock States table. Those were there for… uh, many years now.
Not sure how that relates to Zero RPM though. That feature is strictly temperature based, voltage and clock state is irrelevant to it. The card can be in its full 3D state, but under light load (like an old game) and if it stays below whatever the thermal threshold of the model is it also won’t engage the fans.

Thanks, i'v not been keeping up with modern cards, so I'm completely out of touch. Besides this I'n running older card, So i'm going to change the title of thread (if I can) to older cards before zero RPM fan was introduced as standard.

@thread

It seems older cards can run zero RPM fan speed also before it became standard. I have just tested a Vega 56 Nano for the first time by jamming the fan until I find a software solution. Here's the result stock settings inside small confined PC case.

IDLE 34C

Surfing Web & watching YOUTUBE videos 44 - 46C This is where it stay's most of the time never exceeding/pulling more than 12W.

First photo is a LIVE as of right now from LCD 5'25 bay panel.

Second photo screenshot playing Portal::MEL Stories After 20 mins. ..Most of the time card is pulling 35 - 41W

Of course they can. It’s not some cutting edge feature, it’s just a function of thermals and cooling. You can also nowadays specify a Zero RPM mode via fan controls of the motherboard for your CPU. If the heatsink itself, be it on a GPU or CPU cooler, can effectively dissipate the heat produced by the chip in lower load/power state scenarios, then yes, the fan can stay off. That’s even the whole point of passive cooling. The beefier the heatsink, the higher the threshold for when you might need to activate the fan. In fact, theoretically, if you have a beefy (read - large) enough HS you might never need fans at all. That’s the whole point behind different enthusiast projects for building fully silent PCs, like a case that’s a giant heatsink by itself. The problem with this approach is, obviously, that with higher powered chips running at full load it just becomes impractical - sure, THEORETICALLY you can make a fully passive cooler for, say, the 4090. It just would be so large as to be unusable.
In short, you are correct in tour observations, but they are hardly something that’s non-obvious to anyone who is even remotely knowledgeable about the topic.
