So to get this right, factory sealed liquid coolers don’t need maintenance? Like no topping off the liquid? Do they ever leak? How long do they last? I guess when it comes down to replacing id have to buy a whole new one? I just dont want to do maintenance on one because ill forget about it and ill ruin my rig. I just want to put it in my rig and not have to worry. I will keep an eye on the temps because i have NZXT CAM and i can watch my temps there
