Best OC settings for 2xRTX3060…?

I've been mining RVN since i first found out about it in December last year. I was mining on my pc with a single 1050ti getting about 10RVN/24hours. This quickly turned into a hobby and now I've built my very first dedicated rig with two (for now) 3060 cards. I've applied OC settings found here and they seem to work great, but since the rig is located in a cold room, the cards maintain a stable 51 and 54 degrees measured by the t-rex miner. I noticed that GPU-Z is giving a temp reading called "Hot spot"which usually hangs around 64-67 degrees. Current OC settings are 75% power limit, +150 core clock, +1000 memory clock and 70% fans. My questions exactly are which one of the temperature readings should I worry about, are the temps im getting good and are there any better OC settings that I can try for maximizing the hash rate of the cards…?
