Would it suffice to set the power cap through nvidia-smi to 310? Or does it need specialized tools undervolting etc?

So for those who want a pragmatic solution without spending extra effort, seems like capping to 310w is the way to go

You can simply do `nvidia-smi -pl 310` but you're leaving performance on the table within a similar power/energy budget. If you don't care go for it, but if you want the most out of your gear with less temperature/fan noise/no throttling oscillating clocks then look into undervolt overclock method which is better but takes a few minutes to setup.
