Zalman Reserator-2 Pumps?

[monoboogie]

I have a Zalamn Reserator v2 watercooling system hooked up to my overclocked Q6600 and to my 8800gt.

The reserator is known for its weak pump, and due to my placement, the tubing is quite long.

I was looking to add a booster water pump to aid in the flow.

Is it alright to add two pumps to a system? (I know its a newb question, but want to make sure its alright without ruining the pumps)

Also, if I add it right before the cpu block, can it be harmful beacuse the coolant wont have enought time to absorb the heat?

Thanks guys!

Yes, you can add a second pump. But be aware that pumps add heat (even if they're not submerged).
So, what ever cooling you gain from increased flow, may be lost to the additional heat that the second pump will add.

As for the water spending less time in the block (or anywhere else for that matter), flow rate has no effect on residence time. If you for example, double the flow rate, then each time around the loop the water spends half as much time in the block, but then it comes back through the block twice as often.

If it worked the way you're thinking (long residence time being good) then everyone would be using very small, slow pumps. We use our larger pumps because they increase turbulence inside the water block (and the radiator). It's the increased turbulence, not the increased flow that produces the increased cooling.
