Water cooling and super powerful water pump

[azev]

I got a question for our watercooling master here;

What is the ups and down of having super powerfull waterpump that can pump 250 gallons per hour on a watercooling system ?

Thx

Flow will not matter if the pressure curve is crap...... how much pressure will it push??
Which pump are you talking about?

Right not the best wc pumps are the ddc+/mcp655(the 18w version) with the alphacool plexy top, or other aftermarket top.

dont think pushing more water throught the sink will help cool...ive found that there is a happy medium between to slow and to fast that the water should flow....the slower the flow the better heat pick up the water has and the better heat release in the radiator...you need to find that happy medium and stick with it....more doesnt always mean better

First, 250gph is not "super powerfull," for a very brief period I used a spare 2000gph pump (it was designed to use 1 inch fittings) and it decreased my performance from the 720gph pump I was using. If you consider speed alone then faster is always better but in reality bigger pumps produce more heat and the cooling gains get smaller and smaller. Thus going from 1000gph to 2000gph will raise temps a 2c or more. A 250gph pump won't raise the watter anymore than 1c in temp. and should produce lower or at least equal temps on the CPU than a say 150gph pump.

Also, the big concern really isn't gph it's pressure (generally measured in terms of "head room" or "max height" or "gph at a given height"). I would say that a 250gph pump is a good idea if you plan to have a big radiator, cpu-block, vga-block and possibly a northbridge cooler.

If you get a super powerful pump, you'll be dumping too much heat into the loop. I believe www.procooling.com had some information on that kinda stuff. There's an iwazaki-60 or something like that. Should be overkill already.

D5/MCP655 is a good mid-high end pump. I wouldn't put it in a system with SLI and a Storm (like mine ) but I really had no choice ($$$) and didn't feel like doing a two loop system.
