Undervolting RTX 3090 help

[RedelZaVedno]

Hi all. I got used RTX 3090 FE and all went well until I noticed hot my room gets when using it, we're hitting +35C outside these days
I googled for 3090's efficiency curve graph and couldn't find any. All I could find is that miners used 1600Mhz 750mv as a mining sweetspot. Would that be the same for gaming?
Maybe some of you know what is the general consensus how much to undervolt/underclock to still get decent performance and bring heat/wattage down?

You have to play around with it. Start with the power limit and lower it to 90, 80, 70, 60% and then try undervolting. Monitor your GPU power usage, as the less power(Watts) it pulls the less heat it gives out.

Try 1800mhz/ 800mV undervolt, it will reduce power consumption by at least 70W quite keeping close to stock performance
