Water cooling help

There are three pumps im looking at 400lph 600lph and 800lph

now im only going to be using it on the cpu for cooling im guessing 800lpm is overkill
so out off the 400 and 600 lpm what would i best off be getting plus i am going to upgrade my cooling for the 7870 gpu to a water cooling block

400lpm? Are you trying to cool your truck? Are you sure that's not lph (liters per hour)?

This is a pretty good reference if you have your mind set on water cooling.

Forgot to mention:
"Cooling" is by definition, the removal of Heat. To remove heat efficiently, you must have a good heat transfer from the heat source to the coolant and from the coolant to the air. Coolant that moves too fast is just as bad as too slow. Until you can determine a flow rate that works best for the components you select for your system, I would advise that you include a way to change the flow rate.

If they are adjustable and that rating is a "max" flow rate, always go bigger than you need right now, especially if you are planning an upgrade. I know next to nothing about water cooling pumps, but that is a good rule of thumb across the board. If you think the 400lph pump will be enough now, I'd say get the 600. You can always turn it down(if it is adjustable) but you can't turn one up more than the maximum rate.

That's true but you don't want the pump to cavitate because of lack of input coolant either. A bypass reservoir may be needed. Every change in a system components will make the system react differently. And that includes tubing and radiator surface area and even the coolant itself. All I'm saying is that if you are building your own system from scratch, you'll need to experiment with the components to achieve the ideal cooling system for your PC. Otherwise, your just slapping a bunch of parts together and hoping the best. Just keep in mind that coolant must have time to absorb heat as well as release it. And just plain old distilled water has one of the highest heat transfer properties. The more you add to it, such as boiling point enhancers, heat transfer goes down so flow must go down to achieve the same cooling efficiency.
