Thanks Skinnee

If I understand the graphs, we get: Graph2- between a 14 1/2 and 5 3/4 deg change in temp. based on fan speeds, while cooling 300 watts. This would seem acceptable. I'll need to look at Martinms testing and try and familiarize myself with the terminology and methodology so I can understand the parameters here. But from what I can gleen so far, I should be fine for my gpu's on the 220 without the addition of the 120.

You did mean just 1 4870x2 right?

yes

ok...just making sure. :up:

Q is constant throughout the loop, but v and A can vary. A decrease in area (like a nozzle) would mean an increase in v.

If there is a small hole to pass through, the liquid will go faster but the number that comes out of the equation will be exactly the same.

Gotchya!

Flowrate and Velocity are obviously two different things. Thanks for the clarification.
