Hopefully my image posted correctly. If not I'll try again. I recently configured and ordred a watercooling kit from various vendors. I posted a thread about my concern that the MCP350 wouldn't have enough power to maintain adequate flow rates through the Black Ice III. This was based on my faulty assumption that it was a four pass radiator. I calculated the total head required for the loop to be 52". Factor in restriction of the loop, any pressure drops, and I fiqured I would be getting flow rates as if it were at 100" (though this was just a guess). At such a high head the flow rate would be very low.
Assuming that my picture posted correctly, follow my logic as I walk you through the loop. From the pump the water flows to the CPU water block 10" above the pump. From there gravity pulls it downward through the VGA blcok and to the inlet of the radiator (this part of the loop has no effect on the pump's head). From there (assuming that the Pro III is a four pass radiator which it isn't) the water would have to travel vertically 14" twice. This would add 28" to the required head. From the outlet of the radiator the water would have to travel vertically to the reservior 14". My reasoning is that the pump, without any considerations for flow restriction or pressure drops, would require at least 52" or 4.3' of head. Anyone think I'm correct in my reasoning? Anyone think I'm full of junk? Let me know, and thanks for looking. [IMG]
