This is a short question and I don't want to start a new thread, especially since it pertains to my new card, for which I already piggy-backed on this thread.
Anyway, ever since the new 4090 card I've been needing to more diligently micromanage the card fans, for games that are not demanding, like Disco Elysium and the older rpgs.
My previous cards I've simply had to set the fans to start at around 50C, and then scale up according to a custom curve and almost all games seemed to work fine, with 30% fan speed (aprox 1000 rpm) for most games and 40% for heavy ones like CP2077. But the idea was that the games were demanding enought to never allow the card to go back down outside the range I set it to start cooling itself.
I tried the same with the 4090 but on less demanding games the cooling is just too good and it keeps forcing the fans to start and stop. I'm using msi afterburner and fiddle with the hysteresis, but no good since that's more to do with the curve. While in my case the curve never goes over 30 or 40%. I did find a good solution to the issue with setting the fan update interval to the max of 1 min, so when the card slowly builds to 55C the fans start at 30%, and quickly cools the card (under the 1min update interval) back to around 40C (the desktop idle temp) and then the fans stop again until it slowly builds back up to 55C.
This worked fine and I thought I fixed my issue, until I noticed that every now and then the fans no longer stop after the 1 min interval (even though the card has gone under 40C) and it kept cooling it without stopping, until I closed the game. On subsequent starts of the game msi afterburner seemed to work properly. But the first time after a boot it seems to constantly have this issue. I suspect the issue might be that the fan control software of afterburner is conflicting with the fan firmware on the card ... even though I told msi afterburner to always override.
Anyway, it's nothin too serious since its only for less demanding games, but it is annoying to have to keep an eye out for it.
Does nvidia not have some native custom fan controlling software for their cards. I seem to remember, last I searched, that they didn't?
