what seems to be the problem? i figured if i have it setup tight and sealed (i plan to seal up the reservoir as well; i can then run it forever just like i would with a fan.
why clean it every week or evey other week? i think if you add one of those additives, then it should prevent any algae growth or build-up especially in a sealed system...
what definitely requires maintenance? if i must clean it every now and then, water cooling doesn't seem like a viable option for me....
If you seal it, you could probably fire and forget.
For me, silence was the goal. A little maintance is worth not hearing my computer.
Even with a sealed system I would still look in on it every so often. Look for signs of leaks, kinks, check to see if the pump is running fine.
