My gaming pc is on a custom water loop, cpu and gpu. I don’t like leaving it on/asleep, when I’m done with it for the night. If it starts leaking while I’m there on the computer I’ll see or smell it. If it starts leaking while I’m asleep or at work, expensive components are fried.

I’ve been running a custom loop for 10 years at this point and have never once had a leak, bc I flow the loop without power to any components, and with paper towels under each fitting, for like 24 hours each time I change anything out. I’m still always paranoid that shit will just decide to leak on me one day though lol. Also I was having weird issues with wake from sleep and my kvm, to the point where I was having to reboot my pc when I’d sit down at it after work anyway, so why not just shut off and not deal with that frustration after work?

Either way it has nothing to do with power savings.
