Two pumps or what?

[triggaahappee]

What is the benefit of having two pumps on a Koolance RP-452X2 Rev 2.0, as opposed to one pump?

Two pumps or what?

I vote: what.



EDIT: dude, have you read the sticky before you posted this thread?

The pump is the most important component in your watercooling system. If it fails, the watercooling system will not work and you risk damaging your other components.

Dual loops, single loop to increase head pressure or single loop to have a backup pump if one was to fail.

It depends on how many components you're going to be cooling, and how restrictive the blocks are.

Maintaining a half-decent flow rate is very important in order to achieve good cooling, but the difference between a moderate flow rate and a very high flow-rate isn't too great. For example, check out this plot (note that 'lower is better' here). You can see that, as the flow rate drops below about 0.4Gpm, the cooling performance drops off dramatically - but, at flow rates above around 0.8Gpm you gain very little.

So, you will only really see a benefit from the second pump if your system is already highly restrictive, giving you a low flow rate. What components are you cooling? If it's just a CPU and single GPU, then I'd say stick with the single pump.
