nvidia 3d settings power management mode optimal vs adaptive

Most of the ~2-2.2 slot cards don't have enough heatsink to keep RTX 30 cards at a low temp on the desktop, which causes a continuous loop of heating to 60C followed by aggressive fan blowing until the card is back under 40C, rinse and repeat. For this reason the FE, MSI, and EVGA cards tend to be the best for quality of life as all 3 brands have fans that start at ~800rpm.

But on many of the AIB cards this ends up being a much higher RPM on average, so the difference between fanstop at 60C and the initial fan surge at 61C ends up being quite a disturbance. The reason this works for the FE card is because it's a relatively low RPM fan, so a minimum fan speed of 30% is only around 800rpm.

I'm not sure if its laziness, or due to fan hysteresis problems with custom fan curves in Turing cards (most Turing/Pascal AIB cards with PWM control you could tweak custom fan curves from 0-30% without issue), but it seems like this gen Ampere AIBs opted for very basic fan curve BIOSes without much customization (you can see in MSI Afterburner even top end cards have very high minimum fanspeed settings, and fanstop is disabled when custom fan curves are enabled). This generation it seems most of the RTX 30 AIB partner cards have opted to copy the Nvidia FE style of fanstop at 60C + a minimum fanspeed of around 30%, which is a step back from the much better BIOSes that Turing/Pascal AIB cards had, many of which could maintain fan-on always but at a extremely low rotation rate, and/or move where the fanstop position started. The fan curve software for Ampere is a lot clunkier than RDNA2 cards. No demanding games needs that setting to be active.Īs for the 60c thing, all RTX 3080s/3090s have fan stop and have no fan on until 60C. Prefer maximum performance is as Mchart states, for old games that are such a low load on the GPU that it ends up downclocking to 2D clocks, which then drags framerate down below 60. With 'normal' GPU have normal temps (~34 degree) but in games performance is much worse than on radeons.ĭo i really need to set custom profile for every game and change that setting every time i install new game? With 'prefer highest performance' GPU is ON PAIR WITH PREVIOUS RADEONS, but on desktop idle temps are 60 degree and require its fans to cool it down - on desktop while doing nothing! With nvidia there is one major settting in NV control panel that is totally ruining experience - power managment. Radeon Software had 2 issues, that could be fixed with some compromise, but performance and temperatures were pretty good.

What is going on now is beyond my imagination. I had 2 radeons 6800XT and everything was working fine except one detail - cards couldnt work in specific orientation with video outputs facing top - i got brand new case and really wanted this to work, thats my last build so its really 'must have' condition. I really wonder what nvidia broke with 3000 series.
