Question RTX 3080Ti Power Target, Temps and Performance

[cad1882]

Hello,

My Asus Rog Stix 3080 Ti OC was getting uncomfortably warm when playing Cyberpunk - over 70C with default fan profile and ~58-60C with fans cranked up to 100%).
I do know that these temps are well within spec, etc.

So I followed the advice I found on youtube and cranked the Power Target all the way down to 45%.
Much to my surprise, I'm STILL getting solid 60 fps everywhere with the same Ultra settings, yet the temps have dropped basically to idle values.
Can someone explain the physics of this process to me?
Why would a card draw more power and heat up WAY more than it absolutely needs to with the same exact settings and framerate?

Power draw wouldn't increase your temperature. You should be targeting all the way up to 350-400 watt power draw as you've paid for that kind of performance. There's no point in underpowering the card. The thing that increases temp is voltage. You should undervolt. Besides.modern cards post pascal are intended to get high temps as they are self overclocking.
